These instructions are given as a guide to good practice in the installation, start-up, operation, and maintenance by the user, of Trane RTWD/RTUD chillers. They do not contain full service procedures necessary for the continued successful operation of this equipment. The services of a qualiﬁ ed technician should be employed through the medium of a maintenance contract with a reputable service company. Read this manual thoroughly before unit start-up.

Units are assembled, pressure tested, dehydrated, normally charged with refrigerant for RTWD or nitrogen for RTWD-G 51234ze)/RTUD and tested in accordance with factory standard before shipment.

Warnings and cautions

Warnings and Cautions appear at appropriate sections throughout this manual. Your personal safety and the proper operation of this machine require that you follow them carefully. The constructor assumes no liability for installations or servicing performed by unqualiﬁ ed personnel.

WARNING!: Indicates a potentially hazardous situation

which, if not avoided, could result in death or serious injury.

CAUTION!: Indicates a potentially hazardous situation

which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices or for equipment or property-damage-only accidents.

Safety recommendations

To avoid death, injury, equipment or property damage, the following recommendations should be observed during maintenance and service visits:

1. The maximum allowable pressures for system leak testing on low and high pressure side are given in the chapter “Installation”. Insure to do not exceed test pressure by using appropriate device.

2. Disconnect all power supplies before any servicing on the unit.

3. Service work on the refrigeration system and the electrical system should be carried out only by qualiﬁ ed and experienced personnel.

4. To avoid any risk, it is recommended to place the unit on an area with restricted access.

General information

Refrigerant

The refrigerant provided by the manufacturer meets all the requirements of our units. When using recycled or reprocessed refrigerant, it is advisable to ensure its quality is equivalent to that of a new refrigerant. For this, it is necessary to have a precise analysis made by a specialized laboratory. If this condition is not respected, the manufacturer warranty could be cancelled.

Consult the addendum to Manuals for units with refrigerant, for conformity to the Pressure Equipment Directive (PED) 97/23/EC and Machinery Directive 2006/42/EC and for speciﬁ c caution with R1234ze.

Maintenance contract

It is strongly recommended that you sign a maintenance contract with your local Service Agency. This contract provides regular maintenance of your installation by a specialist in our equipment. Regular maintenance ensures that any malfunction is detected and corrected in good time and minimizes the possibility that serious damage will occur. Finally, regular maintenance ensures the maximum operating life of your equipment. We would remind you that failure to respect these installation and maintenance instructions may result in immediate cancellation of the warranty.

Training

To assist you in obtaining the best use of it and maintaining it in perfect operating condition over a long period of time, the manufacturer has at your disposal a refrigeration and air conditioning service school. The principal aim of this is to give operators and technicians a better knowledge of the equipment they are using, or that is under their charge. Emphasis is particularly given to the importance of periodic checks on the unit operating parameters as well as on preventive maintenance, which reduces the cost of owning the unit by avoiding serious and costly breakdown.

Unit Description

The RTWD units are helical-rotary type, water-cooled, liquid chillers, designed for installation indoors. The units have 2 independent refrigerant circuits, with one compressor per circuit. The RTWD units are packaged with an evaporator and condenser.

Note: Each RTWD unit is a completely assembled, hermetic package that is factory-piped, wired, leaktested, dehydrated, charged and tested for proper control operations prior to shipment. The chilled water inlet and outlet openings are covered for shipment.

The RTWD series features Trane’s exclusive Adaptive Control logic with CH530 controls. It monitors the control variables that govern the operation of the chiller unit. Adaptive Control logic can correct these variables, when necessary, to optimize operational efﬁ ciencies, avoid chiller shutdown, and keep producing chilled water. Compressor loading/unloading is provided by:

- Slide valve solenoid activated on RTWD SE, HE and XE versions

- AFD (Adaptive Frequency drive) coordinated with slide valve operation on RTWD HSE

Each refrigerant circuit is provided with ﬁ lter, sight glass, electronic expansion valve, and charging valves on the RTWD.

The evaporator and condenser are manufactured in accordance with Pressure Equipment Directive standards. The evaporator is insulated according the option ordered. Both evaporator and condenser are equipped with water drain and vent connections.

The RTUD units are helical-rotary type compressor chillers. The RTUD unit consists of an evaporator, two helical rotary compressors (one per circuit), oil separators, oil coolers, liquid line service valves, sight glasses, electronic expansion valves and ﬁ lter. The discharge line leaving the oil separator and liquid line entering the ﬁ lters are capped and brazed. The unit ships with a nitrogen holding charge but without oil charge.

Unit Description

Installation overview and requirements.

Contractor responsibilities

A list of the contractor responsibilities typically associated with the RTWD installation process is provided in Table 8.

• Locate and maintain the loose parts. Loose parts are located in the control panel.

• Install the unit on a foundation with ﬂ at support surfaces, level within 5 mm and of sufﬁ cient strength to support concentrated loading. Place the manufacturer-supplied isolation pad assemblies under the unit.

• Install the unit per the instructions outlined in the “Mechanical Installation” section.

• Complete ail water piping and electrical connections.

Note: Field piping must be arranged and supported to avoid stress on the equipment. It is strongly recommended that the piping contractor provide at least 1m of clearance between the pre-installation piping and the planned location of the unit. This will allow for proper ﬁ t-up upon arrival of the unit at the installation site. Ail necessary piping adjustments can be made at that time.

• Where speciﬁ ed, supply and install valves in the water piping upstream and downstream of the evaporator and condenser water boxes, to isolate the shells for maintenance and to balance/trim the system.

• Install ﬂ ow switches or equivalent devices in both the chilled water and condenser water piping. Interlock each switch with the proper pump starter and Tracer CH530, to ensure that the unit can only operate when water ﬂ ow is established.

• Supply and install taps for thermometers and pressure gauges in the water piping, adjacent to the inlet and outlet connections of both the evaporator and the condenser.

• Supply and install drain valves on each water box.

• Supply and install vent cocks on each water box.

• Where speciﬁ ed, supply and install strainers ahead of ail pumps and automatic modulating valves.

• Supply and install refrigerant pressure relief piping from the pressure relief to the atmosphere.

• Start the unit under supervision of a qualiﬁ ed service technician.

• Where speciﬁ ed, supply and insulate the evaporator and any other portion of the unit, as required, to prevent sweating under normal operating conditions.

• For unit-mounted starters, cutouts are provided at the top of the panel for line-side wiring.

• Supply and install the wire terminal lugs to the starter.

• Supply and install ﬁ eld wiring to the line-side lugs of the starter

Unit Description

Unit Storage

If the chiller is to be stored for more than one month prior to installation, observe the following precautions:

• Do not remove the protective coverings from the electrical panel.

• Store the chiller in a dry, vibration-free, secure area.

• At least every three months, attach a gauge and manually check the pressure in the refrigerant circuit. If the refrigerant pressure is below the values in table 9 below, call a qualiﬁ ed service organization and the appropriate Trane sales ofﬁ ce.

NOTE: Pressure will be approximately 1.0 bar if shipped with the optional nitrogen charge.

• This chiller could have been performance tested before shipment. The water boxes drain plugs were withdrawn to avoid the stagnation of the water and possible freeze up under the tubes bundle. Rust colors can be present and are totally normal but they must be wiped off at the time of reception.

Sound Considerations

Refer to Engineering Bulletin for sound consideration applications. Locate the unit away from sound-sensitive areas. Install the isolation pads under the unit. Refer to “Unit Isolation.” Install rubber vibration isolators in all water piping. Use ﬂ exible electrical conduit for ﬁ nal connection to the Tracer UC800. Seal all wall penetrations.

NOTE: Consult an acoustical engineer for critical applications.

Foundation

Provide rigid, non-warping mounting pads or a concrete foundation of sufﬁ cient strength and mass to support the chiller operating weight (including completed piping and full operating charges of refrigerant, oil and water). Refer to General information for unit operating weights. Once in place, level the chiller within 6 mm over its length and width. The manufacturer is not responsible for equipment problems resulting from an improperly designed or constructed foundation.

Vibration Eliminators

Provide rubber boot type isolators for all water piping at the unit. Provide ﬂ exible conduit for electrical connections to the unit.

Isolate all pipe hangers and be sure they are not supported by main structure beams that could introduce vibration into occupied spaces. Make sure that the piping does not put additional stress on the unit.

NOTE: Do not use metal braided type eliminators on the water piping. Metal braided eliminators are not effective at the frequencies at which the unit will operate.

Clearances

Provide enough space around the unit to allow the installation and maintenance personnel unrestricted access to all service points. A minimum of 1 m is recommended for compressor service and to provide sufﬁ cient clearance for the opening of control panel doors. Refer to submittals (documents supplied in document package coming with unit) for minimum clearances required for condenser or evaporator tube service. In all cases, local codes will take precedence over these recommendations. If the room conﬁ guration requires a variance to the clearance dimensions, contact your sales representative.

NOTE: Required vertical clearance above the unit is at least 1 m. There should be no piping or conduit located over the compressor motor.

NOTE: Maximum clearances are given. Depending on the unit conﬁ guration, some units may require less clearance than others in the same category. Heat exchanger tube removal clearance is necessary for detubing and retubing.

Ventilation

The unit produces heat even though the compressor is cooled by the refrigerant. Make provisions to remove heat generated by unit operation from the equipment room. Ventilation must be adequate to maintain an ambient temperature lower than 40°C. Vent the pressure relief valves in accordance with all local and national codes. Refer to “Pressure Relief Valves”. Make provisions in the equipment room to keep the chiller from being exposed to ambient temperatures below 10°C.

Installation – Mechanical

Rigging

The chiller should be moved by lifting or by the base rail designed for forklifting. Refer to the unit model number for more details. Refer to submittal and lifting drawings provided with order/unit to get unit lifting weights and center of gravity dimensions. Refer to the rigging label attached to the unit for further details.

WARNING Lifting and Moving Instructions!

Do not use cables (chains or slings) except as shown. Lifting beam crossbars must be positioned so the lifting cables do not contact the sides of the unit. Each of the cables (chains or slings) used to lift the unit must be capable of supporting the entire weight of the unit. Test lift unit at minimal height to verify even level lift. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even level lift. The high center of gravity on this unit requires the use of an anti-rolling cable (chain or sling). To prevent unit from rolling, attach cable (chain or sling) with no tension and minimal slack around compressor suction pipe as shown. Other lifting arrangements could result in death, serious injury, or equipment damage.

Lifting Procedure

Attach chains or cables to lifting beam, as shown in lifting drawing provided with unit. Lifting beam crossbars MUST be positioned so lifting cables do not contact the sides of the unit. Attach the anti-rolling cable to the circuit 2 compressor suction pipe. Adjust as necessary for even level lift.

Unit Isolation and Leveling

Mounting

Construct an isolated concrete pad for the unit or provide concrete footings at each of the four unit mounting points. Mount the unit directly to the concrete pads or footings. Level the unit using the base rail as a reference. The unit must be level within 5 mm over the entire length and width. Use shims as necessary to level the unit.

Neoprene Isolator Installation (optional)

Install the optional neoprene isolators at each mounting location. Isolators are identiﬁ ed by part number and color.

1. Secure the isolators to the mounting surface, using the mounting slots in the isolator base plate. Do not fully tighten the isolator mounting bolts at this time.

2. Align the mounting holes in the base of the unit, with the threaded positioning pins on the top of the isolators.

3. Lower the unit on to the isolators and secure the isolator to the unit with a nut. Maximum isolator deﬂ ection should be approximately 6.4mm.

Level the unit carefully. Refer to “Leveling”.

Fully tighten the isolators mounting bolts.

NOTICE

Remove Shipping Spacers

For all RTWD 060-120 and all RTUD 060-120, remove and discard the two shipping spacers with four bolts, located underneath the oil separator, as shown in Figure 2 before starting unit. Failure to remove the spacers could result in excessive noise and vibration transmission into the building.

For RTUD 130-270 ton units, remove and discard the four sets of shipping spacers (each including two spacers and one bolt), located within the oil separator mounting brackets, as shown in Figure 3 before starting unit.

Failure to remove the spacers could result in excessive noise and vibration transmission into the building.

RLC-SVX14H-GB

Thoroughly ﬂ ush all water piping to the RTWD/RTUD unit before making the ﬁ nal piping connections to the unit. Components and layout will vary slightly, depending on the location of connections and the water source.

CAUTION Evaporator Damage!

The chilled water connections to the evaporator are to be grooved-pipe type connections. Do not attempt to weld these connections, as the heat generated from welding can cause microscopic and macroscopic fractures on the cast iron water boxes that can lead to premature failure of the water box. To prevent damage to chilled water components, do not allow evaporator pressure (maximum working pressure) to exceed 10 bar.

CAUTION Equipment Damage!

If using an acidic commercial ﬂ ushing solution, construct a temporary bypass around the unit to prevent damage to internal components of the evaporator.

CAUTION Proper Water Treatment!

The use of untreated or improperly treated water in a Chiller may result in scaling, erosion, corrosion, algae or slime. It is recommended that the services of a qualiﬁ ed water treatment specialist be engaged to determine what water treatment, if any, is required. Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water.

CAUTION Use Piping Strainers!

To prevent evaporator or condenser damage, pipe strainers must be installed in the water supplies to protect components from water born debris. Trane is not responsible for equipment-only-damage caused by water born debris.

Drainage

Locate the unit near a large capacity drain for water vessel drain-down during shutdown or repair. Condensers and evaporators are provided with drain connections. Refer to “Water Piping.” All local and national codes apply. A vent is provided on the top of the evaporator at the return end. Be sure to provide additional vents at high points in the piping to bleed air from the chilled water system. Install necessary pressure gauges to monitor the entering and leaving chilled water pressures. Provide shutoff valves in lines to the gauges to isolate them from the system when they are not in use. Use rubber vibration eliminators to prevent vibration transmission through the water lines. If desired, install thermometers in the lines to monitor entering and leaving water temperatures. Install a balancing valve in the leaving water line to control water ﬂ ow balance. Install shutoff valves on both the entering and leaving water lines so that the evaporator can be isolated for service. A pipe strainer must be installed in the entering water line to prevent water-borne debris from entering the evaporator.

Reversing Water Boxes

Water boxes on the evaporator and condenser can NOT be rotated or swapped end for end. Altering the water boxes will lead to poor efﬁ ciency, poor oil management and possible freeze-up of the evaporator.

Evaporator Piping Components

“Piping components” include all devices and controls used to provide proper water system operation and unit operating safety. These components and their general locations are given below.

Entering Chilled Water Piping - ﬁ eld installed

• Air vents (to bleed air from system)

• Water pressure gauges with shutoff valves

Evaporator Piping

Evaporator Drain Flow Proving Devices

The installer must provide ﬂ ow switches or differential pressure switches with pump inter-locks to prove system water ﬂ ow. To provide chiller protection, install and wire ﬂ ow switches in series with the water pump interlocks, for both chilled water and condenser water circuits (refer to the Installation - Electrical section). Speciﬁ c connections and schematic wiring diagrams are shipped with the unit.

Flow switches must prevent or stop compressor operation if either system water ﬂ ow drops off below the required minimum shown on the pressure drop curves. Follow the manufacturer’s recommendations for selection and installation procedures. General guidelines for ﬂ ow switch installation are outlined below.

CAUTION!

Evaporator Damage!

For all RTWD-RTUD units, chilled water pumps MUST be controlled by the Trane CH530 to avoid catastrophic damage to the evaporator due to freezing.

• Mount the switch upright on a horizontal portion of

water outlet pipe, with a minimum of 5 pipe diameters run on each side of the switch.

• Do not install close to elbows, oriﬁ ces or valves.

NOTE: The arrow on the switch must point in the direction of the water ﬂ ow.

• To prevent switch ﬂ uttering, remove all air from the

water system

NOTE: The CH530 provides a 6-second time delay on the ﬂ ow switch input before shutting down the unit on a loss-of-ﬂ ow diagnostic. Contact a qualiﬁ ed service organization if nuisance machine shutdowns persist.

• Adjust the switch to open when water ﬂ ow falls

below minimum. Refer to the General Data table for minimum ﬂ ow recommendations for speciﬁ c water pass arrangements. Flow switch contacts are closed on proof of water ﬂ ow.

Note: To prevent evaporator damage, do not use water ﬂ ow switch to cycle the system.

Condenser water inlet and outlet types, sizes and locations are given in the Unit Dimensions and Weights. Condenser pressure drops are shown in Figure 6.

Condenser Piping Components

Condenser piping components and layout vary, depending on the location of connections and the water source. Condenser piping components generally function identically to those in the evaporator piping system, as described in “Evaporator Piping”. In addition, cooling tower systems should include a manual or automatic bypass valve that can alter the water ﬂ ow rate, to maintain condensing pressure. Well water (or city water) condensing systems should include a pressure reducing valve and a water regulating valve. Pressure reducing valve should be installed to reduce water pressure entering the condenser. This is required only if the water pressure exceeds 10 bar. This is necessary to prevent damage to the disc and seat of the water regulating valve that can be caused by excessive pressure drop through the valve and also due to the design of the condenser. The condenser waterside is rated at 10 bar.

CAUTION Equipment Damage!

To prevent damage to the condenser or regulating valve, the condenser water pressure should not exceed 10 bar. The optional water regulating valve maintains condensing pressure and temperature by throttling water ﬂ ow leaving the condenser in response to compressor discharge pressure. Adjust the regulating valve for proper operation during unit start-up. Refer to RLC-PRB021-EN for further details regarding condenser water temperature control.

Note: Plugged tees are installed to provide access for chemical cleaning of the condenser tubes. Condenser piping must be in accordance with all applicable local and national codes.

Condenser Drains

The condenser shells can be drained by removing the drain plugs from the bottom of the condenser heads. Also, remove the vent plugs at the top of the condenser heads to facilitate complete drainage. When the unit is shipped, the drain plugs are removed from the condenser and placed in a plastic bag in the control panel, along with the evaporator drain plug. The condenser drains may be connected to suitable drains to permit drainage during unit servicing. If they are not, the drain plugs must be installed.

CAUTION! In case of low evaporator leaving water temperature applications, the non use of glycol on the condenser side may result in condenser tube freeze-up.

Water Regulating Valve

Water Treatment

Using untreated or improperly treated water in these units may result in inefﬁ cient operation and possible tube damage. Consult a qualiﬁ ed water treatment specialist to determine whether treatment is needed. The following disclamatory label is provided on each RTWD unit:

CAUTION Proper Water Treatment! The use of untreated or improperly treated water in a Chiller may result in scaling, erosion, corrosion, algae or slime. It is recommended that the services of a qualiﬁ ed water treatment specialist be engaged to determine what water treatment, if any, is required. Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water.

For leaving chilled water temperatures below 3.3°C, it is mandatory to operate the unit with the appropriate freeze inhibitor (glycol type and percentage) in both evaporator and condenser water loops.

Water Pressure Gauges

Install ﬁ eld-supplied pressure gauges (with manifolds, whenever practical) on the RTWD units. Locate pressure gauges or taps in a straight run of pipe; avoid placement near elbows, etc. Be sure to install the gauges at the same elevation. To read manifolded pressure gauges, open one valve and close the other (depending upon the reading desired). This eliminates errors resulting from differently calibrated gauges installed at unmatched elevations.

Water Pressure Relief Valves

Install a water pressure relief valve in the condenser and evaporator leaving chilled water piping. Water vessels with close coupled shutoff valves have a high potential for hydrostatic pressure buildup on a water temperature increase. Refer to applicable codes for relief valve installation guidelines.

CAUTION Prevent Shell Damage!

To prevent shell damage, install pressure relief valves in both the evaporator and condenser water systems.

Refrigerant Relief Valve Venting

To prevent injury due to inhalation of R134a or R1234ze gases, do not discharge refrigerant anywhere. If multiple chillers are installed, each unit must have separate venting for its relief valves. Consult local regulations for any special relief-line requirements.

All relief-valve venting is the responsibility of the installing contractor.

Note: After being opened once, relief valves tend to leak.

Condenser Pressure Relief Valve Venting

All RTWD units utilize a refrigerant-pressure relief valve for each circuit which must be vented to the outdoor atmosphere. The valves are located at the top of the condenser. Refer to local codes for relief valve vent line sizing requirements.

Note: Vent line length must not exceed code recommendations. If the line length will exceed code recommendations for the outlet size of the valve, install a vent line of the next larger pipe size.

RTUD units are not equipped with refrigerant pressure relief valve on the high pressure side. The safety valve calibration installed on refrigerant piping or on the condenser must not exceed 25 bar.

CAUTION Equipment Damage!

To prevent capacity reduction and relief valve damage, do not exceed vent piping code speciﬁ cations. RTWD relief valve discharge setpoints are 21 bar rel. Once the relief valve has opened, it will reclose when pressure is reduced to a safe level. Pipe each relief valve on the unit into a common vent line. Provide access valve located at the low point of the vent piping, to enable draining of any condensate that may accumulate in the piping.

WARNING Contains Refrigerant!

System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives. Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or serious injury or equipment damage. If multiple chillers are installed, each unit must have a separate venting for its relief valves. Consult local regulations for any special relief line requirements.

Note: Units can be ordered with “Dual Relief Valve” options. Model number digit 16 is a “2”. RTWD units this option will have 4 total relief valves.

RTUD Installation

The installation of a split system offers a good economic alternative to satisfy the chilled water demand for cooling a building, particularly in the case of new construction.

Releasing the Nitrogen Holding Charge

The nitrogen holding charge can be released into the atmosphere.

CAUTION! When releasing nitrogen holding charge, ventilate the room. Avoid breathing in the nitrogen.

System Conﬁ guration

The system can be conﬁ gured in any of the primary arrangements as shown in Figure 8 and 9. The conﬁ guration and its associated elevation, along with the total distance between the RTUD and the air-cooled condenser, plays a critical role in determining the liquid line and discharge line sizes. This will also affect the ﬁ eld refrigerant and oil charges. Consequently, there are physical limits which must not be violated if the system is to operate as designed. Please note the following restrictions:

1. The discharge line sizing is different for different leaving evaporator water temperatures.

2. The total distance between the RTUD and the aircooled condenser must not exceed 61 m actual or 91 m equivalent.

3. Liquid line risers must not exceed 4.5 m from the base of the air-cooled condenser.

4. Discharge line risers cannot exceed an elevation difference greater than 30 m (actual) without a minimum of 2% efﬁ ciency decrease.

5. Refer to Figure 9 for location of recommended traps.

6. Circuit #1 on the condenser must be connected to Circuit # 1 on the RTUD unit.

CAUTION

Equipment Damage!

If circuits are crossed, serious equipment damage may occur.

Equivalent Line Length

To determine the appropriate size for ﬁ eld installed liquid and discharge lines, it is ﬁ rst necessary to establish the equivalent length of pipe for each line, including the added ﬂ ow resistance of elbows, valves, etc. An initial approximation can be made by assuming that the equivalent length of pipe is 1.5 times the actual pipe length.

NOTE: Table 10 states the equivalent length, for various non-ferrous valves and ﬁ ttings. When calculating the equivalent length, do not include piping of the unit. Only ﬁ eld piping must be considered.

CAUTION! RTUD is only a component of a complete installation. It includes its own high pressure protection set at 23 bar. The party in charge of the supply of the condenser and of its refrigerant piping is responsible for implementing all required protections to comply with PED requirements for the design pressure of the condenser installed. Refer to the document PROD-SVX01_-XX delivered with this chiller to check all the mandatory conformity requirements of the Pressure Equipment and Machinery directives for this installation.

RLC-SVX14H-GB

Liquid Line Sizing

Trane recommends that the liquid line diameter be as small as possible, while maintaining acceptable pressure drop. This is necessary to minimize refrigerant charge. The total length between the components must not exceed 61 m (actual) or 91 m equivalent.

The liquid line risers must not exceed 4.5 m from the base of the air-cooled condenser. The liquid line does not have to be pitched. Line sizing must be done manually not to violate the 2.8°C subcooling requirement at the EXV.

Liquid lines are not typically insulated. However, if the lines run through an area of high ambient temperature (eg. boiler room), subcooling may drop below required levels. In these situations, insulate the liquid lines.

Use of a liquid line receiver is not recommended because it adds to the overall refrigerant volume of the circuit.

Note: In case of power failure to the expansion valve, the amount of liquid refrigerant contained in the refrigerant system must not exceed the holding capacity of the evaporator. See Table 11 for the maximum allowable charge in each circuit.

Discharge (Hot Gas) Line Sizing

The discharge lines should pitch downward, in the direction of the hot gas ﬂ ow, at the rate of 12.5 mm per each 3 meters of horizontal run.

Discharge line size is based on the velocity needed to obtain sufﬁ cient oil return.

Discharge lines are not typically insulated. If insulation is required, it should be approved for use at temperatures up to 110°C (max discharge temp).

Note: The discharge line should drop well below the compressor discharge outlet before beginning its vertical rise. This prevents possible refrigerant drainage back to the compressor and oil separator during the unit STOP cycle. Refer to Figure 8 and 9 for details.

Split system installation

Page 34

RLC-SVX14H-GB

Refrigerant Charge Determination

The approximate amount of the refrigerant charge required by the system must be determined by referring to Table 11 and must be veriﬁ ed by running the system and checking the liquid line sightglasses.

Note: The maximum charge can reduce the maximum length of the piping. Due to maximum allowable refrigerant charge not all units can have 61 m of piping.

To determine the approximate charge, ﬁ rst refer to Table 11 and establish the required charge without the ﬁ eld-installed piping. Then refer to Table 12, to determine the charge required for the ﬁ eld-installed piping. The approximate charge is therefore the sum of the values from Table 11 and Table 12.

Note: The amounts of refrigerant listed in Table 12 are based on 30 m of pipe. Actual requirements will be in direct proportion to the actual length of the piping.

Note: Table 12 assumes: Liquid Temperature = 41°C; Saturated Discharge Temperature = 52°C; Discharge Superheat = 16.7°C.

NOTICE REFRIGERANT CHARGING!

Equipment Damage

Add initial ﬁ eld refrigerant charge only through the service valve on the liquid line, not the service valves on the evaporator, and insure that water is ﬂ owing through the evaporator during the charging process. Failure to do the above could result in equipment damage.

RTUD Chilled Water Flow Control

CAUTION

Equipment Damage

ALL RTUD unit chilled water pumps MUST be controlled by the Trane CH530 to avoid catastrophic damage to the evaporator due to freezing.

Oil Charge Determination

The RTUD unit is factory charged with the amount of oil required by the system. No additional oil is required for ﬁ eld installed piping.

Outdoor Air Temperature Sensor Installation Requirements

The outdoor air temperature sensor is optional for the RTWD water cooled units, but is a required sensor for the RTUD compressor chiller units. The sensor is required as an important input to the condenser fan control algorithm as well as for the low outdoor air ambient lockout feature. The temperature sensor probe is shipped separately inside the control panel.

It is necessary for the chiller installer to locate and install the separate outdoor air sensor probe at the remote air cooled condenser at a location to sense the coil’s entering air temperature, while avoiding direct sunlight. It should be located at least 5.1 cm from the coil face and somewhere “in-between” the two refrigerant circuits. Where the condenser installation is such that the two refrigerant circuit’s condensers are physically separate from each other, or one circuit is more likely to see re-circulated warmer air, an attempt should be made to locate the probe to see an average temperature of the two separate condensers. Note: it is important that the probe provided not be substituted with another probe, as the probe and the electronics are “matched / calibrated” at the factory for accuracy.

A twisted pair sheathed cable shall be run and connected between the probe at the remote condenser and its LLID module in the chiller control panel. The sensor’s circuit is a class II power limited analog circuit and therefore the wire should not be run in close proximity to any power or line voltage wiring. The splices at the condenser end, should be made to be water tight. The wire run should be physically supported at equal intervals with consideration for safety and reliability/durability with wire ties or similar to meet local codes.

Fan Control for the Remote Air Cooled Condenser

The CH530 Controls for the RTUD compressor chiller provide as an option, the ﬂ exible and full control of 2-circuit remote air cooled condenser fans. In addition to the option for controlling between 2 to 8 ﬁ xed speed fans per circuit (or multiples thereof), a separate additional option includes the ability to control either two speed fans or variable speed fan/drive combinations in conjunction with other ﬁ xed speed fans, to provide low ambient outdoor air temperature capability. The controls will also provide an option for a simple per circuit interlock output (in lieu of actual fan control) to use in the scenario in which independent fan head pressure or differential pressure controls (by others) is applied. It is recommended however, that for the best overall unit performance, the integral fan control option is selected.

The controls support control of a remote, air cooled condenser fan deck, from 2 to 8 fans per circuit (1-8 fans for variable speed). It supports options to control the following types of standard ambient outdoor air temperature fan decks: 1) all fans ﬁ xed speed, and 2) all fans two speed. It will also support the following low ambient outdoor air temperature fan decks 1) one fan per circuit is Two-Speed, (remaining fans ﬁ xed speed), and 2) One fan per circuit is variable speed i.e. variable frequency drive (VFD), (remaining fans ﬁ xed speed). In the variable fan low ambient outdoor air option the VFD fan and ﬁ xed speed fans are sequenced accordingly to provide continuous control from 0-100% air ﬂ ow per circuit. Fan staging provides the correct combination of ﬁ xed speed fan relay, VFD relay (to enable operation of the VFD), and speed outputs to provide air ﬂ ow control commanded by the fan algorithm running inside the CH530 Main Processor. The fan deck arrangement is independently conﬁ gurable per circuit.

Since the condenser is provided separately from the RTUD compressor chiller, the RTUD electrical panel design does not provide for condensing unit’s control power requirements. The chiller’s control power transformer is not sized to provide the control power for the additional fan contactor loads. The CH530 controls, when properly optioned, will provide for pilot duty rated relays, low voltage binary inputs, and low voltage analog outputs to control the remote contactors and inverters provided by others. The CH530 fan control relays located in the chiller control panel, are intended to control the fan contactors that are located in the remote air cooled condenser panel. The Fan Control Relays are rated for up to 7.2 Amps resistive, 2.88 Amps pilot duty 1/3 HP, 7.2 FLA at 120 VAC, and up to 5 Amps general purpose at 240 VAC. All wiring for the ﬁ eld connections to the condenser, will have screw terminals for termination in the RTUD control panel with the exception of the outdoor air temperature sensor (addressed above). Refer to the wiring diagrams.

Separate fan control algorithms are used for ﬁ xed speed and variable speed systems. For the variable speed fan deck option, the fan control reverts to ﬁ xed speed control if an inverter drive fault is detected through a binary input interface with the drive. An informational diagnostic is also provided to indicate the issue.

For more fan control information, reference “Controls Interface” chapter sections.

RTUD Condenser Elevation Setting

Condenser elevation setting is a require input during startup of an RTUD chiller, and is accessible in TechView, on the Unit View Screen. Go to the Unit View/ Chiller Tab, select Condenser Elevation setting and enter condenser elevation in appropriate units. Reference Figure 10. The shipped default of this setting is 0 and it represents the distance of the bottom of the condenser, relative to the top of the evaporator. Use a positive value for the condenser above the evaporator and a negative value for the condenser below the evaporator. An estimate to within +/- 91 cm is required.

Condenser elevation setting allows proper EXV operation. Failure to properly set the elevation can result in low pressure cutout trips, or low differential pressure trips during startup or large load transients, as well as poor EXV liquid level control during operation.

Electrical Parts

When reviewing this manual keep in mind.

• All ﬁ eld-installed wiring must be in accordance with local regulations, CE directives and guidelines. Be sure to satisfy proper equipment grounding requirements according CE

• The following standardized values - Maximum Amps Short Circuit Amps - Starting Amps are displayed on unit nameplate.

• All ﬁ eld-installed wiring must be checked for proper terminations, and for possible shorts or grounds.

Note: always refer to wiring diagrams shipped with chiller or unit submittal for speciﬁ c electrical schematic and connection information.

WARNING! Hazardous Voltage with Capacitor!

Disconnect all electric power, including remote disconnects and discharge all motor start/run and AFD (Adaptive Frequency TM Drive) capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized.

RTWD HSE version

• Time before to work on the electrical panel of the unit: once the AFD is off (conﬁ rmed by the extinction of the display), it is mandatory to wait one minute before working on the electrical panel.

• However, for any intervention in the AFD, the indicated time on the label of the AFD must be respected. Before installing the chiller with HSE version, the user must evaluate the potential electromagnetic problems in the surrounding area. The following should be considered:

a) the presence above , below and adjacent to the unit of for example: welding equipment or other power cables, control cables or signaling and telephone cables;

b) receivers and transmitters, radio and television;

c) computer and other control equipment;

d) the critical safety equipment, eg protection of industrial equipment;

e) the health of neighboring persons, for example, use of pacemakers or appliances against deafness;

f) the immunity of other equipment in the environment. The user must ensure that the other materials used in the environment are compatible. This may require additional protection measures;

If electromagnetic disturbances are detected, it shall be the responsibility of the user to resolve the situation. In any case, the electromagnetic interferences have to be reduced until they are no longer troublesome.

• For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharges capacitors. Verify with an appropriate voltmeter that all capacitors have discharged

• DC bus capacitors retain hazardous voltages after input power has been disconnected. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. After disconnecting input power, wait twenty (20) minutes for units which are equipped with variable frequency drive (0V DC) before touching any internal components.

Failure to follow these instructions could result death or serious injury.

For additional information regarding the safe discharge of capacitors, see “Adaptive Frequency™ Drive (AFD3) Capacitor Discharge” and BAS-SVX19B-E4.

Hazardous Voltage – Pressurized Burning Fluid!

Before removing compressor terminal box cover for servicing, or servicing power side of control panel, CLOSE COMPRESSOR DISCHARGE SERVICE VALVE and disconnect all electric power including remote disconnects. Discharge all motor start/run capacitors. Follow lockout/tagout procedures to ensure the power cannot be inadvertently energized. Verify with an appropriate voltmeter that all capacitors have discharged.

The compressor contains hot, pressurized refrigerant. Motor terminals act as a seal against this refrigerant. Care should be taken when servicing NOT to damage or loosen motor terminals.

Do not operate compressor without terminal box cover in place.

Failure to follow all electrical safety precautions could result in death or seriously injure.

General Electrical Recommendations

Page 38

RLC-SVX14H-GB

CAUTION! To avoid corrosion, overheating or general damage, at terminal connections, unit is designed for copper mono-conductors only. In case of multiconductor cable, an intermediate connection box must be added. For cable with alternative material, bi-material connecting devices are mandatory. Cable routing inside control panel should be made case by case by installer.

Do not allow conduit to interfere with other components, structural members or equipment. Control voltage (115V) wiring in conduit must be separate from conduit carrying low voltage (<30V) wiring. To prevent control malfunctions, do not run low voltage wiring (<30V) in conduit with conductors carrying more than 30V.

WARNING!

The Warning Label is displayed on the equipment and shown on wiring diagrams and schematics. Strict adherence to these warnings must be observed. Failure to do so may result in personal injury or death.

CAUTION! Units including RTWD HSE units must not be linked to the neutral wiring of the installation. Units are compatible with the following neutral operating conditions:

Control Power Supply

The unit is equipped with a control power transformer; it is not necessary to provide additional control power voltage to the unit. All units are factory-connected for appropriate labeled voltages.

Interconnecting Wiring

Chilled Water Flow (Pump) Interlock

The Model RTWD Series R® chiller requires a ﬁ eldsupplied control voltage contact input through a ﬂ ow proving switch 5S5 and an auxiliary contact 5K9 AUX. Connect the proving switch and auxiliary contact to 1A15 J3-1 and 1X4-1. Refer to the ﬁ eld wiring for details.

The auxiliary contact can be starter contactor auxiliary. or any signal which indicates the pump is running. A ﬂ ow switch is still required and cannot be omitted.

Chilled Water Pump Control

An evaporator water pump output relay closes when the chiller is given a signal to go into the Auto mode of operation from any source. The contact is opened to turn off the pump in the event of most machine level diagnostics to prevent the build up of pump heat.

CAUTION Evaporator Damage!

The RTWD units do NOT require evaporator pump control. All systems with a remote condenser REQUIRE chilled water pumps must be controlled by the Trane CH530 to avoid catastrophic damage to the evaporator due to freezing. The relay output from 1A14 is required to operate the Evaporator Water Pump (EWP) contactor. Contacts should be compatible with 115/240 VAC control circuit. The EWP relay operates in different modes depending on CH530 or Tracer commands, if available, or service pumpdown (See maintenance section). Normally, the EWP relay follows the AUTO mode of the chiller. Whenever the chiller has no diagnostics and is in the AUTO mode, regardless of where the auto command is coming from, the normally open relay is energized. When the chiller exits the AUTO mode, the relay is timed open for an adjustable (using TechView) 0 to 30 minutes. The non-AUTO modes in which the pump is stopped, include Reset (88), Stop (00), External Stop (100), Remote Display Stop (600), Stopped by Tracer (300), Low Ambient Run Inhibit (200), and Ice Building complete (101).Regardless of whether the chiller is allowed to control the pump on a full-time basis, if the MP calls for a pump to start and water does not ﬂ ow, the evaporator may be damaged catastrophically. It is the responsibility of the installing contractor and/or the customer to ensure that a pump will start when called upon by the chiller controls.

Table 20 - Pump Relay Operation

Chiller mode Relay operation Auto Instant close Ice building Instant close Tracer override Close Stop Timed open Ice complete Instant open Diagnostics Instant open

Note: Exceptions are listed below.

When going from Stop to Auto, the EWP relay is energized immediately. If evaporator water ﬂ ow is not established in 4 minutes and 15 sec., the CH530 de-energizes the EWP relay and generates a nonlatching diagnostic. If ﬂ ow returns (e.g. someone else is controlling the pump), the diagnostic is cleared, the EWP is re-energized, and normal control resumed.

If evaporator water ﬂ ow is lost once it had been established, the EWP relay remains energized and a non-latching diagnostic is generated. If ﬂ ow returns, the diagnostic is cleared and the chiller returns to normal operation.

In general, when there is either a non-latching or latching diagnostic, the EWP relay is turned off as though there was a zero time delay. Exceptions (see above table) whereby the relay continues to be energized occur with:

A Low Chilled Water Temp. diagnostic (non-latching) (unless also accompanied by an Evap Leaving Water Temperature Sensor Diagnostic)

A starter contactor interrupt failure diagnostic, in which a compressor continues to draw current even after commanded to have shutdown

A Loss of Evaporator Water Flow diagnostic (nonlatching) and the unit is in the AUTO mode, after initially having proven evaporator water ﬂ ow.

Alarm and Status Relay Outputs (Programmable Relays)

A programmable relay concept provides for enunciation of certain events or states of the chiller, selected from a list of likely needs, while only using four physical output relays, as shown in the ﬁ eld wiring diagram. The four relays are provided (generally with a Quad Relay Output LLID) as part of the Alarm Relay Output Option. The relay’s contacts are isolated Form C (SPDT), suitable for use with 120 VAC circuits drawing up to 2.8 amps inductive, 7.2 amps resistive, or 1/3 HP and for 240 VAC circuits drawing up to 0.5 amp resistive.

The list of events/states that can be assigned to the programmable relays can be found in Table 20. The relay will be energized when the event/state occurs.

Relay Assignments Using TechView

CH530 Service Tool (TechView) is used to install the Alarm and Status Relay Option package and assign any of the above list of events or status to each of the four relays provided with the option. The relays to be programmed are referred to by the relay’s terminal numbers on the LLID board 1A13.

The default assignments for the four available relays of the RTWD Alarm and Status Package Option are:

Table 22 - Default assignments

Relay 1 Terminals J2 -12,11,10: Alarm

Relay 2 Terminals J2 - 9,8,7: Chiller Running

Relay 3 Terminals J2-6,5,4:

Maximum Capacity (software 18.0 or later)

Relay 4 Terminals J2-3,2,1: Chiller Limit

If any of the Alarm/Status relays are used, provide electrical power, 110 VAC with fused disconnect to the panel and wire through the appropriate relays (terminals on 1A13. Provide wiring (switched hot, neutral, and ground connections) to the remote annunciation devices. Do not use power from the chiller’s control panel transformer to power these remote devices. Refer to the ﬁ eld diagrams which are shipped with the unit.

Low Voltage Wiring

WARNING Ground Wire!

All ﬁ eld-installed wiring must be completed by qualiﬁ ed personnel. All ﬁ eld-installed wiring must comply with local codes and regulations. Failure to follow this instruction could result in death or serious injuries.

The remote devices described below require low voltage wiring. All wiring to and from these remote input devices to the control panel must be made with shielded, twisted pair conductors. Be sure to ground the shielding only at the panel.

Note: To prevent control malfunctions, do not run low voltage wiring (<30 V) in conduit with conductors carrying more than 30 volts.

Emergency Stop

CH530 provides auxiliary control for a customer speciﬁ ed/installed latching trip out.

When this customer-furnished remote contact 5K24 is provided, the chiller will run normally when the contact is closed. When the contact opens, the unit will trip on a manually resettable diagnostic. This condition requires manual reset at the chiller switch on the front of the control panel.

Connect low voltage leads to terminal strip locations on 1A5, J2-3 and 4. Refer to the ﬁ eld diagrams that are shipped with the unit. Silver or gold-plated contacts are recommended. These customer-furnished contacts must be compatible with 24 VDC, 12 mA resistive load.

External Auto/Stop

If the unit requires the external Auto/Stop function, the installer must provide leads from the remote contacts 5K23 to the proper terminals on 1A5 J2-1 and 2. The chiller will run normally when the contacts are closed. When either contact opens, the compressor(s), if operating, will go to the RUN:UNLOAD operating mode and cycle off. Unit operation will be inhibited. Closure of the contacts will permit the unit to return to normal operation. Field-supplied contacts for all low voltage connections must be compatible with dry circuit 24 VDC for a 12 mA resistive load. Refer to the ﬁ eld diagrams that are shipped with the unit.

External Circuit Lockout – Circuit #1 and Circuit #2

CH530 provides auxiliary control of a customer speciﬁ ed or installed contact closure, for individual operation of either Circuit #1 or #2. If the contact is closed, the refrigerant circuit will not operate 5K21 and 5K22. Upon contact opening, the refrigerant circuit will run normally. This feature is used to restrict total chiller operation, e.g. during emergency generator operations. Connections to 1A10 are shown in the ﬁ eld diagrams that are shipped with the unit. These customer-supplied contact closures must be compatible with 24 VDC, 12 mA resistive load. Silver or gold plated contacts are recommended.

Installation – Electrical

Page 64

RLC-SVX14H-GB

Ice Building Option

CH530 provides auxiliary control for a customer speciﬁ ed/installed contact closure for ice building if so conﬁ gured and enabled. This output is known as the Ice Building Status Relay. The normally open contact will be closed when ice building is in progress and open when ice building has been normally terminated either through Ice Termination setpoint being reached or removal of the Ice Building command. This output is for use with the ice storage system equipment or controls (provided by others) to signal the system changes required as the chiller mode changes from “ice building” to “ice complete”. When contact 5K20 is provided, the chiller will run normally when the contact is open. CH530 will accept either an isolated contact closure (External Ice Building command) or a Remote Communicated input (Tracer) to initiate and command the Ice Building mode. CH530 also provides a “Front Panel Ice Termination Setpoint”, settable through TechView, and adjustable from -6.7 to -0.5°C in at least 1°C increments. When in the Ice Building mode, and the evaporator entering water temperature drops below the ice termination setpoint, the chiller terminates the Ice Building mode and changes to the Ice Building Complete Mode.

CAUTION

Evaporator Damage!

Freeze inhibitor must be adequate for the leaving water temperature. Failure to do so may result in damage to system components.

Techview must also be used to enable or disable Ice Machine Control. This setting does not prevent the Tracer from commanding Ice Building mode.

Upon contact closure, the CH530 will initiate an ice building mode, in which the unit runs fully loaded at all times. Ice building shall be terminated either by opening the contact or based on the entering evaporator water temperature. CH530 will not permit the ice building mode to be reentered until the unit has been switched out of ice building mode (open 5K20 contacts) and then switched back into ice building mode (close 5K20 contacts.)

In ice building, all limits (freeze avoidance, evaporator, condenser, current) will be ignored. All safeties will be enforced. If, while in ice building mode, the unit gets down to the freeze stat setting (water or refrigerant), the unit will shut down on a manually resettable diagnostic, just as in normal operation. Connect leads from 5K20 to the proper terminals of 1A10. Refer to the ﬁ eld diagrams which are shipped with the unit. Silver or gold-plated contacts are recommended. These customer furnished contacts must be compatible with 24 VDC, 12 mA resistive load.

External Chilled Water Setpoint (ECWS) Option

The CH530 provides inputs that accept either 4-20 mA or 2-10 VDC signals to set the external chilled water setpoint (ECWS). This is not a reset function. The input deﬁ nes the setpoint. This input is primarily used with generic BAS (building automation systems). The chilled water setpoint set via the DynaView or through digital communication with Tracer (Comm3). The arbitration of the various chilled water setpoint sources is described in the ﬂ ow charts at the end of the section.

The chilled water setpoint may be changed from a remote location by sending either a 2-10 VDC or 4-20 mA signal to the 1A7, J2-1 and 2. The 2-10 VDC and 4-20 mA each correspond to a -12 to 18°C external chilled water setpoint.

Installation – Electrical

The following equations apply:

Voltage signal Current signal

As generated from external source VDC = 0.1455* (ECWS)+0.5454 mA = 0.2909 (ECWS)+1.0909 As processed by CH530 ECWS = 6.875*(VDC)-3.75 ECWS= 3.4375(mA)-3.75

Page 65

RLC-SVX14H-GB

If the ECWS input develops an open or short, the LLID will report either a very high or very low value back to the main processor. This will generate an informational diagnostic and the unit will default to using the Front Panel (DynaView) Chilled Water Setpoint. TechView Service Tool is used to set the input signal type from the factory default of 2-10 VDC to that of 4-20 mA. TechView is also used to install or remove the External Chilled Water Setpoint option as well as a means to enable and disable ECWS.

External Current Limit Setpoint (ECLS) Option

Similar to the above, the CH530 also provides for an optional External Current Limit Setpoint that will accept either a 2-10 VDC (default) or a 4-20 mA signal. The Current Limit Setting can also be set via the DynaView or through digital communication with Tracer (Comm

3). The arbitration of the various sources of current limit is described in the ﬂ ow charts at the end of this section. The External Current Limit Setpoint may be changed from a remote location by hooking up the analog input signal to the 1A7, J2-4 and 5. Refer to the following paragraph on Analog Input Signal Wiring Details. The following equations apply for ECLS:

Voltage signal Current signal

As generated from external source

VDC + 0.133* (%)-6.0 mA = 0.266*(%)-12.0

As processed by CH530

%=7.5*(VDC)+ 45.0 %=3.75*(mA)+ 45.0

If the ECLS input develops an open or short, the LLID will report either a very high or very low value back to the man processor. This will generate an informational diagnostic and the unit will default to using the Front Panel (DynaView) Current Limit Setpoint. The TechView Service Tool must be used to set the input signal type from the factory default of 2-10 VDC to that of 4-20 mA current. TechView must be also be used to install or remove the External Current Limit Setpoint Option for ﬁ eld installation, or can be used to enable or disable the feature (if installed).

ECLS and ECWS Analog Input Signal Wiring Details:

Both the ECWS and ECLS can be connected and setup as either a 2-10 VDC (factory default), 4-20 mA, or resistance input (also a form of 4-2OmA) as indicated below. Depending on the type to be used, the TechView Service Tool must be used to conﬁ gure the LLID and the MP for the proper input type that is being used. This is accomplished by a setting change on the Custom Tab of the Conﬁ guration View within TechView.

The J2-3 and J2-6 terminal is chassis grounded and terminal J2-1 and J2-4 can be used to source 12 VDC. The ECLS uses terminals J2-2 and J2-3. ECWS uses terminals J2-5 and J2-6. Both inputs are only compatible with high-side current sources.

Chilled Water Reset (CWR)

CH530 resets the chilled water temperature set point based on either return water temperature, or outdoor air temperature. Return Reset is standard, Outdoor Reset is optional.

The following shall be selectable:

• One of three Reset Types: None, Return Water Temperature Reset, Outdoor Air Temperature Reset, or Constant Return Water Temperature Reset.

• Reset Ratio Set Points.

• For outdoor air temperature reset there shall be both positive and negative reset ratio’s.

• Start Reset Set Points.

• Maximum Reset Set Points.

The equations for each type of reset are as follows:

Return

and CWS’ > or = CWS

and CWS’ - CWS < or = Maximum Reset

Outdoor

CWS’ = CWS + RATIO * (START RESET - TOD)

and CWS’ > or = CWS

and CWS’ - CWS < or = Maximum Reset

where

CWS’ is the new chilled water set point or the “reset CWS”

CWS is the active chilled water set point before any reset has occurred, e.g. normally Front

Panel, Tracer, or ECWS

RESET RATIO is a user adjustable gain

START RESET is a user adjustable reference

TOD is the outdoor temperature

TWE is entering evap. water temperature

TWL is leaving evap. water temperature

MAXIMUM RESET is a user adjustable limit providing the maximum amount of reset. For all types of reset, CWS’ - CWS < or = Maximum Reset.

In addition to Return and Outdoor Reset, the MP provides a menu item for the operator to select a Constant Return Reset. Constant Return Reset will reset the leaving water temperature set point so as to provide a constant entering water temperature. The Constant Return Reset equation is the same as the Return Reset equation except on selection of Constant Return Reset, the MP will automatically set Ratio, Start Reset, and Maximum

Reset to the following:

RATIO = 100%

START RESET = Design Delta Temp.

MAXIMUM RESET = Design Delta Temp.

The equation for Constant Return is then as follows:

CWS’ = CWS + 100% (Design Delta Temp. - (TWE - TWL))

and CWS’ > or = CWS

and CWS’ - CWS < or = Maximum Reset

When any type of CWR is enabled, the MP will step the Active CWS toward the desired CWS (based on the above equations and setup parameters) at a rate of 1 degree C every 5 minutes until the Active CWS equals the desired CWS’. This applies when the chiller is running.

When the chiller is not running the CWS is reset immediately (within one minute) for Return Reset and at a rate of 1 degree C every 5 minutes for Outdoor Reset. The chiller will start at the Differential to Start value above a fully reset CWS or CWS’ for both Return and Outdoor Reset.

External Analog Output

As an option, CH530 provides a 2-10 VDC analog output to indicate condenser pressure. The conﬁ guration item provides for the installation of the necessary hardware and software as well as deﬁ nes which of two possible ways the output is conﬁ gured. The selections for the conﬁ guration item are as follows:

1) Analog voltage output is a function of percent HPC condenser pressure - Percent HPC Condenser Pressure Indication

The transfer function is 2 to 10 Vdc corresponding to 0 Psia (or kPa abs) and the Software High Pressure Cutout (HPC) setting in Psia (or kPa abs). The Percent HPC Condenser Pressure indication output is based on the Condenser Refrigerant Pressure transducers.

Note: For the RTWD and RTUD chillers, the High Pressure Cutout Setting is replaced by the Software High Pressure Cutout setting, (The Software HPC is a conﬁ guration setting and is deﬁ ned as an absolute pressure (its inherent units is Kpa (abs)). For multiple circuit chillers, such as RTWD, the condenser pressure used in the calculation will be the lowest condenser pressure of all of the running circuits. Condenser pressure transducers that are invalid (i.e. noncommunicative or out of range) will be excluded. Note: If both transducers are invalid, then output shall 1.0 VDC (per the table below), but if only one is invalid, the opposite transducers value shall be used for the analog output.

For this feature:

Percent HPC = ((Lowest Condenser Pressure of all running circuits (abs) / Software HPC conﬁ guration setting in absolute units*100.

The following equations are applied:

2) Analog voltage output is a function of refrigerant differential pressure with the endpoints customer deﬁ ned in the Refrigerant Pressure Analog Output settings - Refrigerant Differential Pressure Indication

The transfer function is 2 to 10 Vdc corresponding from the “Differential Pressure Output Minimum Pressure” setting to the “Differential Pressure Output Maximum Pressure” setting. Both settings are conﬁ guration settings in the service tool. Since the calculations relate to pressure differences, they can be made in either gauge or absolute as long as they are consistent. For multiple circuit chillers, such as RTWD, the refrigerant differential pressure used in the calculation will be the lowest differential pressure of all of the running circuits. If a given circuit’s Condenser or Evaporator pressure transducers that are invalid (i.e. non-communicative or out of range) that circuit’s DP will be excluded. Note: If both circuits have at least one pressure transducer invalid, then output shall 1.0 VDC (per the table below), but if only one circuit has an invalid pressure transducer, the opposite circuit’s DP value shall be used for the analog output.

For this feature:

Refrigerant Differential Pressure = Lowest of (condenser refrigerant pressure ckt x - evaporator refrigerant pressure ckt x)

The “Differential Pressure Output Minimum and Maximum Pressure” conﬁ guration settings are not a negative number and the Refrigerant Differential Pressure used in the calc shall be clamped to be never less than zero.

The following equations are applied:

Refrigeration (Cooling) Cycle

Overview

The refrigeration cycle of the Series R chiller is conceptually similar to that of other Trane chiller products. It makes use of a shell-and-tube evaporator design with refrigerant evaporating on the shell side and water ﬂ owing inside tubes having enhanced surfaces.

The compressor is a twin-rotor helical rotary type. It uses a suction gas-cooled motor that operates at lower motor temperatures under continuous full and part load operating conditions. An oil management system provides an almost oil-free refrigerant to the shells to maximize heat transfer performance, while providing lubrication and rotor sealing to the compressor. The lubrication system ensures long compressor life and contributes to quiet operation.

For RTWD units, condensing is accomplished in a shelland-tube heat exchanger where refrigerant is condensed on the shell side and water ﬂ ows internally in the tubes.

For RTUD units, condensing is accomplished in a remote air-cooled condenser unit. The refrigerant ﬂ ows through the tubes in the condenser. Air ﬂ ows over the coils in the condenser, removing the heat and condensing the refrigerant.

A unit-mounted starter (Wye delta on SE, HE, PE Versions or AFD on HSE versions) and control panel is provided on every chiller. Microprocessor-based unit control modules (Tracer CH530) provide for accurate chilled water control as well as monitoring, protection and adaptive limit functions. The “adaptive” nature of the controls intelligently prevents the chiller from operating outside of its limits, or compensates for unusual operating conditions, while keeping the chiller running rather than simply tripping due to a safety concern. When problems do occur, diagnostic messages assist the operator in troubleshooting.

Cycle Description

The refrigeration cycle for the RTWD/RTUD chiller can be described using the pressure-enthalpy diagram shown in Figure 15. Key State Points are indicated on the ﬁ gure and are referenced in the discussion following.

Figure 15 - Pressure/Enthalpy Curve

L= Liquid G = Gas P = Pressure E = Enthalpy

Page 74

RLC-SVX14H-GB

Evaporation of refrigerant occurs in the evaporator. A metered amount of refrigerant liquid enters a distribution system in the evaporator shell and is then distributed to the tubes in the evaporator tube bundle. The refrigerant vaporizes as it cools the water ﬂ owing through the evaporator tubes. Refrigerant vapor leaves the evaporator as saturated vapor (State Pt. 1).

The refrigerant vapor generated in the evaporator ﬂ ows to the suction end of the compressor where it enters the motor compartment of the suction-gas-cooled motor.

The refrigerant ﬂ ows across the motor, providing the necessary cooling, then enters the compression chamber. Refrigerant is compressed in the compressor to discharge pressure conditions. Simultaneously, lubricant is injected into the compressor for two purposes: (1) to lubricate the rolling element bearings, and (2) to seal the very small clearances between the compressor’s twin rotors. Immediately following the compression process the lubricant and refrigerant are effectively divided using an oil separator. The oil-free refrigerant vapor enters the condenser at State Pt. 2. The lubrication and oil management issues are discussed in more detail in the compressor description and oil management sections that follow.

For RTWD units, a discharge bafﬂ e within the condenser shell distributes the compressed refrigerant vapor evenly across the condenser tube bundle. Cooling tower water, circulating through the condenser tubes, absorbs heat from this refrigerant and condenses it.

For RTUD units, airﬂ ows across the condenser coils, absorbing heat from the refrigerant and condensing it.

As the refrigerant leaves the bottom of the condenser (State Pt. 3), it enters an integral subcooler where it is subcooled before traveling to the electronic expansion valve (State Pt. 4). The pressure drop created by the expansion process vaporizes a portion of the liquid refrigerant. The resulting mixture of liquid and gaseous refrigerant then enters the Evaporator Distribution system (State Pt. 5). The ﬂ ash gas from the expansion process is internally routed to compressor suction, and while the liquid refrigerant is distributed over the tube bundle in the evaporator.

The RTWD/RTUD chiller maximizes the evaporator heat transfer performance while minimizing refrigerant charge requirements. This is accomplished by metering the liquid refrigerant ﬂ ow to the evaporator’s distribution system using the electronic expansion valve. A relatively low liquid level is maintained in the evaporator shell, which contains a bit of surplus refrigerant liquid and accumulated lubricant. A liquid level measurement device monitors this level and provides feedback information to the CH530 unit controller, which commands the electronic expansion valve to reposition when necessary. If the level rises, the expansion valve is closed slightly, and if the level is dropping, the valve is opened slightly such that a steady level is maintained.

Oil System Operation (RTWD/RTUD)

Overview

Oil that collects in the bottom of the oil separator is at condensing pressure during compressor operation; therefore, oil is constantly moving to lower pressure areas.

As the oil leaves the separator, it passes through the oil cooler. It then goes through the service valve and ﬁ lter. At this point it travels through the master oil valve. Then it provides oil injection and bearing lubrication.

If the compressor stops for any reason, the master oil valve closes, isolating the oil charge in the separator and oil cooler during off periods. The master oil valve is a pressure activated valve. Discharge pressure off the rotors, that is developed when the compressor is on, causes the valve to open.

RLC-SVX14H-GB

Compressor Motor

A two-pole, hermetic, induction motor (3600 rpm at 60 hz, 3000 rpm at 50hz) directly drives the compressor rotors. The motor is cooled by suction refrigerant gas from the evaporator, entering the end of the motor housing through the suction line.

Compressor Rotors

Each compressor has two rotors - “male” and “female” which provide compression.

See Figure 18. The male rotor is attached to, and driven by, the motor, and the female rotor is, in turn, driven by the male rotor. Separately housed bearing sets are provided at each end of both rotors.

The helical rotary compressor is a positive displacement device. The refrigerant from the evaporator is drawn into the suction opening at the end of the motor barrel, through a suction strainer screen, across the motor, and into the intake of the compressor rotor section. The gas is then compressed and discharged directly into the discharge line.

There is no physical contact between the rotors and compressor housing. The rotors contact each other at the point where the driving action between the male and female rotors occurs. Oil is injected along the top of the compressor rotor section, coating both rotors and the compressor housing interior. Although this oil does provide rotor lubrication, its primary purpose is to seal the clearance spaces between the rotors and compressor housing.

A positive seal between these internal parts enhances compressor efﬁ ciency by limiting leakage between the high pressure and low pressure cavities.

Oil Filter

Each compressor is equipped with a replaceable element oil ﬁ lter. The ﬁ lter removes any impurities that could foul the solenoid valve oriﬁ ces and compressor internal oil supply galleries. This also prevents excessive wear of compressor rotor and bearing surfaces.

Compressor Rotor Oil Supply

Oil ﬂ ows through this circuit directly from the master oil ﬁ lter, through the master oil valve to the top of the compressor rotor housing. There it is injected along the top of the rotors to seal clearance spaces between the rotors and the compressor housing and to lubricate the rotors.

Compressor Bearing Oil Supply

Oil is injected into the bearing housings located at each end of both the male and female rotors. Each bearing housing is vented to compressor suction, so that oil leaving the bearings returns through the compressor rotors to the oil separator.

Figure 18 - RTWD Compressor

A = Oil control valve (hidden) B = Female unloader piston C = Discharge check valve D = Female rotor E = Motor terminals F = Suction strainer G = Motor rotor H = Male unloader piston I = Male rotor J = Oil filter

Oil Separator

The oil separator consists of a vertical tube, joined at the top by the refrigerant discharge line from the compressor. This causes the refrigerant to swirl in the tube and throws the oil to the outside, where it collects on the walls and ﬂ ows to the bottom. The compressed refrigerant vapor, stripped of oil droplets, exits out the top of the oil separator and is discharged into the condenser.

Compressor Loading Sequence

The customer has the option to choose either ﬁ xed staging order or balanced start stop.If the CH530 is set with ﬁ xed staging order, compressor A on circuit 1 will start ﬁ rst on a command for cooling, unless a diagnostic has the ﬁ rst compressor locked out. If the ﬁ rst compressor cannot satisfy the demand, the CH530 will start the other compressor and then balance the load on both compressors by pulsing the load/unload solenoids or adjust motor frequency through AFD (Case of HSE version). If the CH530 is set with balanced start stop, the compressor starts vary depending on the compressor wear. The amount of wear on a compressor is calculated by: number of operating hours + starts multiplied by 10. The compressor with the least wear is cycled on ﬁ rst. Once the cooling load is met, the compressor with the most wear is cycled off ﬁ rst.

Slide Valve movement for HSE version

Slide valve operates in HSE versions coordinated with AFD. Tracer UC800 algorithm controls the compressor capacity with higher slide valve capacity and lower AFD frequency to get higher efﬁ ciency.

The loading/unloading schema below is a general ﬁ gure, it could be different in case of sudden modiﬁ cations of the operating data. Also it has not to be considered as a starting/stopping mode.

Unit Voltage Imbalance

Excessive voltage imbalance between the phases of a threephase system can cause motors to overheat and eventually fail. The maximum allowable imbalance is 2%. Voltage imbalance is determined using the following calculations:

% Imbalance =

[(Vx - V ave) x 100/V ave]

V ave = (V1 + V2 + V3)/3

Vx = phase with the greatest difference from V ave (without regard to the sign)

For example, if the three measured voltages are 401, 410, and 417 volts, the average would be:

(401+410+417)/3 = 410

The percentage of the imbalance is then:

[100(410-401)/410] = 2.2%

This exceeds the maximum allowable (2%) by 0.2%.

Unit Voltage Phasing

It is important that proper rotation of the compressors be established before the unit is started. Proper motor rotation requires conﬁ rmation of the electrical phase sequence of the power supply. The motor is internally connected for clockwise rotation with the incoming power supply phased A, B, C.

Basically, voltages generated in each phase of a polyphase alternator or circuit are called phase voltages. In a three-phase circuit, three sine wave voltages are generated, differing in phase by 120 electrical degrees. The order in which the three voltages of a three-phase system succeed one another is called phase sequence or phase rotation. This is determined by the direction of rotation of the alternator. When rotation is clockwise, phase sequence is usually called “ABC”, when counterclockwise, “CBA”.

This direction may be reversed outside the alternator by interchanging any two of the line wires. It is this possible interchange of wiring that makes a phase sequence indicator necessary if the operator is to quickly determine the phase rotation of the motor.

Proper compressor motor electrical phasing can be quickly determined and corrected before starting the unit. Use a quality instrument, such as the Associated Research Model 45 Phase Sequence Indicator.

1. Press the Stop key on the Clear Language Display.

2. Open the electrical disconnect or circuit protection switch that provides line power to the line power terminal block(s) in the starter panel (or to the unit mounted disconnect).

3. Connect the phase sequence indicator leads to the line power terminal block, as follows:

Phase Sea. Lead Terminal

Phase A L1

Phase B L2

Phase C L3

4. Turn power on by closing the unit supply power fused-disconnect switch.

5. Read the phase sequence on the indicator. The “ABC” LED on the face of the phase indicator will glow if phase is “ABC”.

6. If the “CBA” indicator glows instead, open the unit main power disconnect and switch two line leads on the line power terminal block(s) (or the unit mounted disconnect). Reclose the main power disconnect and recheck the phasing.

CAUTION Equipment Damage!

Do not interchange any load leads that are from the unit contactors or the motor terminals.

7. Reopen the unit disconnect and disconnect the phase indicator.

RTWD HSE version

• However, for any intervention in the AFD, the indicated time on the label of the AFD must be respected.

Water System Flow Rates

Establish a balanced chilled water ﬂ ow through the evaporator. The ﬂ ow rates should fall between the minimum and maximum values. Chilled water ﬂ ow rates below the minimum values will result in laminar ﬂ ow, which reduces heat transfer and causes either loss of EXV control or repeated nuisance, low temperature cutouts. Flow rates that are too high can cause tube erosion.

The ﬂ ow rates through the condenser must also be balanced. The ﬂ ow rates should fall between the minimum and maximum values.

Water System Pressure Drop

Measure water pressure drop through the evaporator and condenser at the ﬁ eld-installed pressure taps on the system water piping. Use the same gauge for each measurement. Do not include valves, strainers ﬁ ttings in the pressure drop readings.

Pressure drop readings should be approximately those shown in the Pressure Drop Charts starting with Figure 4.

CAUTION Equipment Damage!

Ensure that the oil separator and compressor heaters have been operating for a minimum of 24 hours before starting. Failure to do so may result in equipment damage.

Start-up

If the pre-start checkout, has been completed, the unit is ready to start.

1. Press the STOP key on the CH530.

2. As necessary, adjust the setpoint values in the CH530 menus using TechView.

3. Close the fused-disconnect switch for the chilled water pump. Energize the pump(s) to start water circulation.

4. Check the service valves on the discharge line, suction line, oil line and liquid line for each circuit. These valves must be open (backseated) before starting the compressors.

CAUTION Compressor Damage!

Catastrophic damage to the compressor will occur if the oil line shut off valve or the isolation valves are left closed on unit start-up.

5. Press the AUTO key. If the chiller control calls for cooling and all safety interlocks are closed, the unit will start. The compressor(s) will load and unload in response to the leaving chilled water temperature.

6. Verify that the chilled water pump runs for at least one minute after the chiller is commanded to stop (for normal chilled water systems).

Note: Once the system has been operating for approximately 30 minutes and has become stabilized, complete the remaining start-up procedures, as follows:

7. Check the evaporator refrigerant pressure and the condenser refrigerant pressure under Refrigerant Report on the CH530 TechView. The pressures are referenced to sea level (1.0135 bar abs).

8. Check the EXV sight glasses after sufﬁ cient time has elapsed to stabilize the chiller. The refrigerant ﬂ ow past the sight glasses should be clear. Bubbles in the refrigerant indicate either low refrigerant charge or excessive pressure drop in the liquid line or a stuck open expansion valve. A restriction in the line can sometimes be identiﬁ ed by a noticeable temperature differential between the two sides of the restriction. Frost will often form on the line at this point. Proper refrigerant charges are shown in the General Data tables.

Note: Important! A clear sight glass alone does not mean that the system is properly charged. Also check system subcooling, liquid level control and unit operating pressures.

9. Measure the system subcooling.

10. A shortage of refrigerant is indicated if operating pressures are low and subcooling is also low. If the operating pressures, sight glass, superheat and subcooling readings indicate a refrigerant shortage, gas-charge refrigerant into each circuit, as required. With the unit running, add refrigerant vapor by connecting the charging line to the suction service valve and charging through the backseat port until operating conditions become normal.

Seasonal Unit Start-Up Procedure

1. Close all valves and re-install the drain plugs in the evaporator and condenser heads.

2. Service the auxiliary equipment according to the start-up/maintenance instructions provided by the respective equipment manufacturers.

3. Vent and ﬁ ll the cooling tower, if used, as well as the condenser and piping. At this point, all air must be removed from the system (including each pass). Close the vents in the evaporator chilled water circuits.

4. Open all the valves in the evaporator chilled water circuits.

5. If the evaporator was previously drained, vent and ﬁ ll the evaporator and chilled water circuit. When all air is removed from the system (including each pass), install the vent plugs in the evaporator water boxes.

6. Verify condenser coils are clean.

CAUTION Equipment Damage!

Ensure that the oil separator and compressor heaters have been operating for a minimum of 24 hours before starting. Failure to do so may result in equipment damage.

CAUTION Compressor Damage!

Catastrophic damage to the compressor will occur if the oil line shut off valve or the isolation valves are left closed on unit start-up.

Overview

This section describes preventative maintenance procedures and intervals for the RTWD unit. Use a periodic maintenance program to ensure optimal performance and efﬁ ciency of the Series R units.

An important aspect of the chiller maintenance program is the regular completion of the “Series R Operating Log”; an example of this log is provided in this manual. When ﬁ lled out properly the completed logs can be reviewed to identify any developing trends in the chiller’s operating conditions.

For example, if the machine operator notices a gradual increase in condensing pressure during a month’s time, he can systematically check for and then correct, the possible cause(s) of this condition (e.g., fouled condenser tubes, non-condensables in the system).

CAUTION

Refrigerant!

If both suction and discharge pressures are low but sub-cooling is normal, a problem other than refrigerant shortage exists. Do not add refrigerant, as this may result in overcharging the circuit.

Use only refrigerants speciﬁ ed on the unit nameplate (R134a or R1234ze) and Trane OIL 048E on SE, HE, PE versions with R134a, OIL00317 on HSE version with 134a and OIL066E or OIL067E for R1234ze. Failure to do so may cause compressor damage and improper unit operation.

CAUTION

Equipment Damage!

Ensure that the oil separator and compressor heaters have been operating for a minimum of 24 hours before starting. Failure to do so may result in equipment damage.

Maintenance

WARNING Hazardous Voltage!

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

RTWD HSE version

• However, for any intervention in the AFD, the indicated time on the label of the AFD must be respected.

WARNING Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.

Weekly Maintenance and Checks

After the unit has operated for approximately 30 minutes and the system has stabilized, check the operating conditions and complete the procedures below:

• Log the chiller.

• Check evaporator and condenser pressures with gauges and compare to the reading on the CH530. Pressure readings should fall within the speciﬁ ed ranges listed under Operating Conditions.

Note: Optimum condenser pressure is dependent on condenser water temperature, and should equal the saturation pressure of the refrigerant at a temperature 1 to 3°C above that of leaving condenser water at full load.

Monthly Maintenance and Checks

• Review operating log.

• Clean all water strainers in both the chilled and condensing water piping systems.

• Measure the oil ﬁ lter pressure drop. Replace oil ﬁ lter if required. Refer to “Service Procedures”.

• Measure and log the subcooling and superheat.

• If operating conditions indicate a refrigerant shortage, leak check the unit and conﬁ rm using soap bubbles.

• Repair all leaks.

• Trim refrigerant charge until the unit operates in the conditions listed in the note below.

Note: Eurovent conditions are condenser water: 30/35°C and evaporator water: 12/7°C.

WARNING

Hazardous Voltage!

RTWD HSE version

• However, for any intervention in the AFD, the indicated time on the label of the AFD must be respected.

• Perform all weekly and monthly maintenance procedures.

• Check the refrigerant charge and oil level. Refer to “Maintenance Procedures”. Routine oil changing is not necessary on a hermetic system.

• Have a qualiﬁ ed laboratory perform an oil analysis to determine system moisture content and acid level.

Note: Due to the hygroscopic properties of the POE oil, all oil must be stored in metal containers. The oil will absorb water if stored in a plastic container.

• Check the pressure drop across the oil ﬁ lter. Refer to “Maintenance Procedures”.

• Contact a qualiﬁ ed service organization to leak check the chiller, to inspect safety controls, and inspect electrical components for deﬁ ciencies.

• Inspect all piping components for leakage and/or damage. Clean out any inline strainers.

• Clean and repaint any areas that show signs of corrosion.

• Test vent piping of all relief valves for presence of refrigerant to detect improperly sealed relief valves. Replace any leaking relief valve.

• Inspect the condenser tubes for fouling; clean if necessary. Refer to “Maintenance Procedures”.

• Check to make sure that the crank case heater is working.

Scheduling Other Maintenance

• Use a nondestructive tube test to inspect the condenser and evaporator tubes at 3- year intervals.

Note: It may be desirable to perform tube tests on these components at more frequent intervals, depending upon chiller application. This is especially true of critical process equipment.

• Depending on chiller duty, contact a qualiﬁ ed service organization to determine when to conduct a complete examination of the unit to determine the condition of the compressor and internal components.

Note: Do not swap R134a by R1234ze without intervention of Trane Service organization for advice on technical changes.

Service Procedures

Cleaning the Condenser (RTWD Only)

CAUTION Proper Water Treatment!

The use of untreated or improperly treated water in a RTWD may result in scaling, erosion, corrosion, algae or slime. It is recommended that the services of a qualiﬁ ed water treatment specialist be engaged to determine what water treatment, if any, is required. The Trane Company assumes no responsibility for equipment failures which result from untreated or improperly treated water, saline or brackish water. At 65°C condensing leaving water temperature and above, it is mandatory to have condensor equipped with CuNi tubes.

Condenser tube fouling is suspect when the “approach” temperature (i.e., the difference between the refrigerant condensing temperature and the leaving condenser water temperature) is higher than predicted.

Standard water applications will operate with less than a

5.5°C approach. If the approach exceeds 5.5°C cleaning the condenser tubes is recommended.

Note: Glycol in the water system may as much as double the standard approach.

If the annual condenser tube inspection indicates that the tubes are fouled, 2 cleaning methods can be used to rid the tubes of contaminants.The methods are:

Mechanical Cleaning Procedure

Mechanical tube cleaning method is used to remove sludge and loose material from smooth-bore condenser tubes.

 WARNING

Heavy Objects!

Each of the individual cables (chains or slings) used to lift the waterbox must be capable of supporting the entire weight of the waterbox. The cables (chains or slings) must be rated for overhead lifting applications with an acceptable working load limit. Failure to properly lift waterbox could result in death or serious injury.

 WARNING

Eyebolts!

The proper use and ratings for eyebolts can be found in ANSI/ASME standard B18.15. Maximum load rating for eyebolts are based on a straight vertical lift in a gradually increasing manner. Angular lifts will signiﬁ cantly lower maximum loads and should be avoided whenever possible. Loads should always be applied to eyebolts in the plane of the eye, not at some angle to this plane. Failure to properly lift waterbox could result in death or serious injury.

Review mechanical room limitations and determine the safest method or methods of rigging and lifting the waterboxes.

Chemical Cleaning Procedure

• Scale deposits are best removed by chemical means. Consult a qualiﬁ ed water treatment specialist (i.e., one that knows the local water supply chemical/mineral content) for a recommended cleaning solution suitable for the job. (A standard condenser water circuit is composed solely of copper, cast iron and steel.) Improper chemical cleaning can damage tube walls.

Table 31 - Connection devices

Unit Product

RTWD/RTUD - All units Safety Hoist Ring M12x1.75

• All of the materials used in the external circulation system, the quantity of the solution, the duration of the cleaning period, and any required safety precautions should be approved by the company furnishing the materials or performing the cleaning.

Note: Chemical tube cleaning should always be followed by mechanical tube cleaning with R134a, OIL00317 on HSE version with 134a and OIL066E or OIL067E for R1234ze.

Compressor Oil

CAUTION Equipment Damage!

To prevent oil sump heater burnout, open the unit main power disconnect switch before removing oil from the compressor.

Trane Polyolester Oil is the approved oil for the RTWD/ RTUD units. Polyolester oil is extremely hygroscopic meaning it readily attracts moisture. The oil can not be stored in plastic containers due to the hygroscopic properties. As with mineral oil, if water is in the system it will react with the oil to form acids. Use Table 32 to determine the acceptability of the oil.

Trane approved oil :

R134a : OIL048E and OIL023E on SE, HE, XE version OIL 00317 for HSE version with AFD.

R1234ze: OIL066E and OIL067E.

The proper charge amounts are given in general data tables.

Note: Use an oil transfer pump to change the oil regardless of chiller pressure.

Table 32 - POE Oil Properties

Description Acceptable levels Moisture content Less than 300 ppm Acid level Less that 0.5 TAN (mg KOH/g)

Oil Sump Level Check

Running the chiller at minimum load is the best for the quickest return of oil to the separator and sump. The machine still needs to sit for approximately 30 minutes before the level is taken. At minimum load, the discharge superheat should be highest. The more heat in the oil as it lays in the sump, the more refrigerant will boil off in the sump and leave more concentrated oil.

The oil level in the oil sump can be measured to give an indication of the system oil charge. Follow the procedures below to measure the level.

1. Run the unit fully unloaded for approximately 20 minutes.

2. Cycle the compressor off line.

CAUTION Oil Loss!

Never operate the compressor with the sightglass service valves opened. Severe oil loss will occur. Close the valves after checking the oil level. The sump is above the condenser and it is possible to drain the oil.

Figure 23 - Determining Oil Level in Sump

A = Oil separator service valve B = Oil sump service valve C = 10-24cm

3. Attach a 3/8” or 1/2” hose with a sightglass in the middle to the oil sump service valve (1/4” ﬂ are) and the oil separator service valve (1/4” ﬂ are).

Note: Using high pressure rated clear hose with appropriate ﬁ ttings can help speed up the process.

4. After the unit is off line for 30 minutes, move the sightglass along the side of the oil sump.

5. The level should be between 10-24 cm from the bottom of the oil sump. If the level appears to be above 24 cm, the oil sump is completely full. Most likely more oil resides in the rest of the system and some oil needs to be removed until the level falls between 10-24 cm in the oil sump.

Note: Nominal height of oil is 20 cm.

Service and Maintenance

Page 91

RLC-SVX14H-GB

6. If the level is below 10cm, there is not enough oil in the sump. This can occur from not enough oil in the system or more likely, oil migration to the evaporator. Oil migration can occur from a low refrigerant charge, gas pump malfunction, etc.

Note: If the oil is logged in the evaporator conﬁ rm the operation of the gas pump. If the gas pump is not functioning properly all oil will be logged in the evaporator.

7. After the level is determined, close the service valves and remove the hose/sightglass assembly.

Removing Compressor Oil

The oil in the compressor oil sump is under a constant positive pressure at ambient temperature. To remove oil, open the service valve located on the bottom of the oil sump and drain the oil into a suitable container using the procedure outlined below:

CAUTION POE Oil!

Due to the hygroscopic properties of the POE oil, all oil must be stored in metal containers. The oil will absorb water if stored in a plastic container.

Oil should not be removed until the refrigerant is isolated or removed.

1. Connect a line to the oil sump drain valve.

2. Open the valve and allow the desired amount of oil to

ﬂ ow into the container and close the charging valve.

3. Measure the exact amount of oil removed from

the unit.

Oil Charging Procedure

It is critical to ﬁ ll the oil lines feeding the compressor when charging a system with oil. The diagnostic “Loss of oil at the compressor stopped” will be generated if the oil lines are not full on start-up.

To properly charge the system with oil, follow the steps below:

1. Locate the 1/4” schrader valve on the end of the

compressor.

2. Loosely connect oil pump to schrader valve called out

in step 1.

3. Operate oil charging pump until oil appears at

the charging valve connection; then tighten the connection.

Note: To keep air from entering the oil, the charging valve connection must be air- tight.

4. Open the service valve and pump in the required

amount of oil.

Note: Adding oil at the oil charging port ensures that the oil ﬁ lter cavity and the oil lines back to the oil separator are ﬁ lled with oil. An internal oil valve prevents oil from entering the compressor rotors.

Replacing the Oil Filter

The ﬁ lter element should be changed if the oil ﬂ ow is sufﬁ ciently obstructed. Two things can happen: ﬁ rst, the chiller may shut down on a “Low Oil Flow” diagnostic, or secondly, the compressor may shut down on a “Loss of Oil at Compressor (Running) diagnostic.

If either of these diagnostics occurs, it is possible the oil ﬁ lter needs replacement. The oil ﬁ lter is not usually the cause of a Loss of oil at Compressor diagnostic.

Speciﬁ cally, the ﬁ lter must be changed if the pressure drop between the two service valves in the lubrication circuit exceeds the maximum level as given in Figure 24. This chart shows the relationship between the pressure drop measured in the lubrication circuit as compared with operating pressure differential of the chiller (as measured by pressures in the condenser and evaporator).

Normal pressure drops between the service valves of the lubrication circuit are shown by the lower curve. The upper curve represents the maximum allowable pressure drop and indicates when the oil ﬁ lter must be changed. Pressure drops that lie between the lower and upper curves are considered acceptable.

For a chiller equipped with an oil cooler, add 0.3 bar to the values shown in Figure 24. For example, if the system pressure differential was 5.5 bar, then the clean ﬁ lter pressure drop would be approximately 1 bar (up from 0.7 bar). For a chiller with an oil cooler and operating with a dirty oil ﬁ lter, the maximum allowable pressure drop would be 1.9 bar (up from 1.6 bar).

Under normal operating conditions the element should be replaced after the ﬁ rst year of operation and then as needed thereafter.

Service and Maintenance

Page 92

RLC-SVX14H-GB

Refrigerant Charge

If a low refrigerant charge is suspected, ﬁ rst determine the cause of lost refrigerant. Once the problem is repaired follow the procedures below for evacuating and charging the unit.

Evacuation and Dehydration

1. Disconnect ALL power before/during evacuation.

2. Connect the vacuum pump to the 5/8” ﬂ are connection on the bottom of the evaporator and/or condenser.

3. To remove all of the moisture from the system and to insure a leak free unit, pull the system down below 500 microns.

4. After the unit is evacuated, perform a standing rise test for at least an hour. The pressure should not rise more than 150 microns. If the pressures rises more than 150 microns, either a leak is present or moisture is still in the system.

Note: If oil is in the system, this test is more difﬁ cult. The oil is aromatic and will give off vapors that will raise the pressure of the system.

Refrigerant Charging

Once the system is deemed leak and moisture free, use the 5/8” ﬂ are connections at the bottom of the evaporator and condenser to add refrigerant charge. Refer to General Data Tables and Unit nameplate for refrigerant charge information.

Refrigerant and Oil Charge Management

Proper oil and refrigerant charge is essential for proper unit operation, unit performance, and environmental protection. Only trained and licensed service personnel should service the chiller.

Some symptoms of a refrigerant under-charged unit:

• Low subcooling

• Higher than normal discharge superheat

• Bubbles in EXV sight glass

• Low liquid level diagnostic

• Larger than normal evaporator approach temperatures (leaving water temperature - saturated evaporator temperature)

• Low evaporator refrigerant temperature limit

• Low refrigerant temperature cutout diagnostic

• Fully open expansion valve

• Possible whistling sound coming from liquid line (due to high vapor velocity)

• High condenser + subcooler pressure drop

Refrigerant Filter Replacement Procedure

A dirty ﬁ lter is indicated by a temperature gradient across the ﬁ lter, corresponding to a pressure drop. If the temperature downstream of the ﬁ lter is 2.2°C lower than the upstream temperature, the ﬁ lter should be replaced. A temperature drop can also indicate that the unit is undercharged. Ensure proper subcooling before taking temperature readings.

1. With the unit off, verify that the EXV is closed. Close liquid line isolation valve.

2. Attach hose to service port on liquid line ﬁ lter ﬂ ange.

3. Evacuate refrigerant from liquid line and store.

4. Remove hose.

5. Depress schrader valve to equalize pressure in liquid line with atmospheric pressure.

6. Remove bolts that retain ﬁ lter ﬂ ange.

7. Remove old ﬁ lter element.

8. Inspect replacement ﬁ lter element and lubricate o-ring with Trane OIL00048.

NOTE: Do not use mineral oil. It will contaminate the system.

9. Install new ﬁ lter element in ﬁ lter housing.

10. Inspect ﬂ ange gasket and replace if damaged.

11. Install ﬂ ange and torque bolts to 19-22 N;m.

12. Attach vacuum hose and evacuate liquid line.

13. Remove vacuum hose from liquid line and attach

charging hose.

14. Replace stored charge in liquid line.

15. Remove charging hose.

16. Open liquid line isolation valve.

Freeze Protection

For unit operation in a low temperature environment, adequate protection measures must be taken against freezing.

This timetable is applicable to units operating in normal conditions with an average of 4000 hours per year. If operating conditions are abnormally severe, an individual timetable must be made for that unit.

(1) Tube testing required if aggressive water conditions exist. Applies to condensers only on water cooled

units.

(2) Schedule as per previous analysis result or at least once a year.

(3) Year 1 to deﬁ ne equipment baseline. Subsequent year based on oil analysis results or schedule as per

vibration analysis.

(4) Recommended at 40 000 run hours or 100 000 equivalent operating hours whichever comes ﬁ rst.

Oil analysis

Trane Oil Analysis is a predictive tool used to detect minor issues before they become major problems. It also reduces failure detection time and allows planning for appropriate maintenance. Oil changes can be reduced by half resulting in lower operating costs and a lower impact on the environment.

Vibration analysis

Vibration analysis is required when oil analysis reveals the presence of wear indicating the start of possible bearing or motor failure. Trane oil analysis has the ability to identify the type of metallic particles in the oil which, when combined with the vibration analysis, will clearly point out the failing components.

Vibration analysis should be performed on a regular basis to build a vibration trend of the equipment and avoid unplanned downtime and costs.

Compressor R’newal

To ensure a long lifetime for Trane compressors, system oil and vibration are regularly analyzed. These tests build a detailed picture of the condition of internal system components. Over time, they also help build a `wear trend’ of the equipment. This informs our service experts whether your compressor is due for minor maintenance or a complete overhaul.
