Application Considerations

Certain application constraints should be considered when sizing, selecting and installingTrane CGAM chillers. Unit and system reliability is often dependent upon proper and complete compliance with these considerations.Wheretheapplicationvariesfromthe guidelines presented, it should be reviewed with your localTrane account manager.

Note: The terms water and solution are used interchangeably in the following paragraphs.

Unit Sizing

Unit capacities are listed in the Performance Data section. Intentionally over-sizing a unit to assure adequate capacity is not recommended. Erratic system operation and excessive compressor cycling are often a direct result ofan oversized chiller. In addition, an oversized unit is usually more expensive to purchase, install, and operate. If over sizing is desired consider using two smaller units.

WaterTreatment

The use of untreated or improperly treated water in chillers may result in scaling, erosion,

corrosion, and algae or slime buildup.This will adversely affect heat transfer between the water and system components. Proper water treatment must be determined locally and depends on the type of system and local water characteristics.

Neither salt nor brackish water is recommend for use inTrane air-cooled CGAM chillers. Use of either will lead toa shortenedlife.Trane encourages the employment of a qualifiedwater treatment specialist, familiar with local water conditions, to assist in the establishment of a proper water treatment program.

Foreign matter in the chilled water system can also increase pressure drop and, consequently, reduce water flow. For this reason it is important to thoroughly flush all water piping to the unit before making the final piping connections to the unit.

The capacities give in the Performance Data section of this catalog are based on water with a

fouling factor of 0.0001°F·ft²·h/Btu (in accordance withAHRI550/590).For capacities at other fouling factors, see Performance Selection Software.

Effect of Altitude on Capacity

Chiller capacities given in the Performance Data section are based upon application at sea level. At elevations substantially above sea level, the decreased air density will decrease condenser capacity and, therefore, unit capacity and efficiency.

Ambient Limitations

Trane chillers are designed for year-round operation over a range of ambient temperatures.The air-

cooled model CGAM chiller will operate in ambient temperatures of 32°F to 125°F (0°C to 52°C) for high ambient or 0°F to 125°F (-18°C to 52°C) for wide ambient. Operation down to 0°F requires the use of variable speed fans to modulate and maintain system differential pressure.

The minimum ambient temperatures are based on still conditions (winds not exceeding five mph).

Greater wind velocities will result in a drop in head pressure, therefore increasing the minimum starting and operating ambient temperature.TheAdaptive Control™ microprocessor will attempt to keep the chiller on-line when high or low ambient conditions exist, making every effort to avoid nuisance trip-outs and provide the maximum allowable tonnage.

Water Flow Limits

The minimum water flow rates are given in the General Data section of this catalog. Evaporator

flow rates below the tabulated values will result in laminar flow causing freeze-up problems, scaling, stratification and poor control.The maximum evaporator water flow rate is also given. Flow rates exceeding those listed may result in very high pressure drop across the evaporator.

Flow Rates Out of Range

Many process cooling jobs require flow rates that cannot be met with the minimum and maximum published values within the CGAM evaporator. A simple piping change can alleviate this problem. For example: a plastic injection molding process requires 80 gpm (5.0 l/s) of 50°F (10°C) water and returns that water at 60°F (15.6°C).The selected chiller can operate at these temperatures, but has a minimum flow rate of 106 gpm (6.6 l/s).The system layout in Figure 1 can satisfy the process.

57°F (14°C) 112 gpm (7 l/s)

Flow Proving

Trane provides a factory-installed water flow switch monitored by CH530 which protects the chiller

from operating in loss of flow conditions.

Variable Flow in the Evaporator

An attractive chilled water system option may be a Variable Primary Flow (VPF) system. VPF systems present building owners with several cost-saving benefits when compared with Primary/ Secondary chilled water systems.The most obvious cost savings results from eliminating the constant volume chiller pump(s), which in turn eliminates the related expenses of the associated piping connections (material, labor), and electrical service and switch gear. In addition to the installed cost advantage building owners often cite pump related energy savings as the reasons that prompted them to select a VPF system.

The CGAM has the capability to handle variable evaporator flow without losing leaving water

temperature control.The microprocessor and capacity control algorithms are designed to take a 10 percent change in water flow rate per minute while maintaining a ±2°F (1.1°C) leaving water temperature control accuracy.The chiller tolerates up to 30 percent per minute waterflow variation as long as the flow is equal or above the minimum flow rate requirement.

With the help of a software analysis tool such as System Analyzer™, DOE-2 orTRACE™, you can

determine whether the anticipated energy savings justify the use of variable primary flow in a particular application. Existing constant flow chilled water systems may be relatively easily converted to VPF and benefit greatly from the inherent efficiency advantages.

Application Considerations

WaterTemperature

Leaving Water Temperature Limits

Trane CGAM chillers have three distinct leaving water categories:

• standard, with a leaving solution range of 42 to 65°F (5.5 to 18°C)

• low temperature process cooling, with leaving solution range of 10 to 65°F (-12 to 18°C)

• ice-making, with leaving solution range of 20 to 65°F (-7 to 18°C)

Since leaving solution temperature below 42°F (5.5°C) results in suction temperature at or below the freezing point of water, a glycol solution is required for all low temperature and ice-making machines. Ice making control includes dual setpoint controls and safeties for ice making and standard cooling capabilities. Consult your localTrane account manager for applications or selections involving low temperature or ice making machines.

The maximum water temperature that can be circulated through the CGAM evaporator when the

unit is not operating is 125°F (51.7°C). Evaporator damage may result above this temperature.

Leaving Water Temperature Out of Range

Similar to the flow rate limitations above, many process cooling jobs require temperature ranges that are outside the allowable minimum and maximum operating values for the chiller. Figure 2 below shows a simple example of a mixed water piping arrangement change that can permit reliable chiller operation while meeting such cooling conditions. For example, a laboratory load requires 238 gpm (5 l/s) of water entering the process at 86°F (30°C) and returning at 95°F (35°C).

The chiller’s maximum leaving chilled water temperature of 65°F (15.6°C) prevents direct supply to

the load. In the example shown, both the chiller and process flow rates are equal, however, this is not necessary. For example, if the chiller had a higher flow rate, there would simply be more water bypassing and mixing with warm water returning to the chiller.

Supply WaterTemperature Drop

The cataloged performance datafor theTraneCGAM chiller is based ona chilled water temperature

drop of 10°F (6°C) for I-P data and 9°F (5°C) for SI data. Full load chilled water temperature drops from 6 to 18°F (3.3 to 10°C) may be used as long as minimum and maximum water temperature and minimum and maximum flow rates are not violated.Temperature drops outside this range at full load conditions are beyond the optimum range for control and may adversely affect the

microcomputer’s ability to maintain an acceptable supply water temperature range. Furthermore, full load temperature drops of less than 6°F (3.3°C) may result in inadequate refrigerant superheat which is critical to long term efficient and reliable operation. Sufficient superheat is always a primary concern in any refrigerant system and is especially important in a packaged chiller where the evaporator is closely coupled to the compressor.

Typical Water Piping

All building water piping must be flushed prior to making final connections to the chiller.To reduce

heat loss and prevent condensation,insulation should be applied.Expansion tanks are alsousually required so that chilled water volume changes can be accommodated.

Avoidance of Short Water Loops

Adequate chilled water system water volume is an important system design parameter because it

provides for stable chilled water temperature control and helps limit unacceptable short cycling of chiller compressors.

The chiller’s temperature control sensor is located in the supply (outlet) water connection or pipe. This location allows the building to act as a buffer to slow the rate of change of the system water

temperature. If there is nota sufficient volume of water in the systemto provide an adequatebuffer, temperature control can suffer, resulting in erratic system operation and excessive compressor cycling.

Typically, a two-minute water loop circulation time is sufficient to prevent short water loop issues. Therefore, as a guideline, ensure the volume of water in the chilled water loop equals or exceeds

two times the evaporator flow rate. For systems with a rapidly changing load profile the amount of volume should be increased.

If the installed system volume does not meet the above recommendations, the following items should be given careful consideration to increase the volume of water in thesystem and,therefore, reduce the rate of change of the return water temperature.

• A volume buffer tank located in the return water piping.

• Larger system supply and return header piping (which also reduces system pressure drop and pump energy use).

Application Considerations

Minimum water volume for a process application

If a chiller is attached to an on/off load such as a process load, it may be difficult for the controller to respond quickly enough to the very rapid change in return solution temperature if the system has only the minimum water volume recommended. Such systems may cause chiller low temperature safety trips or in the extreme case evaporator freezing. In this case, it may be necessary to add or increase the size of the mixing tank in the return line.

Multiple Unit Operation

Whenever two or more units are used on one chilled water loop,Trane recommends that their

operation be coordinated with a higher level system controller for best system efficiency and reliability.The TraneTracer system has advanced chilled plant control capabilities designed to provide such operation.

Ice Storage Operation

An ice storage system uses the chiller to make ice at night when utilities generate electricity more

efficiently and charge less for electricity with lower demand and energy charges.The stored ice reduces or even replaces mechanical cooling during the day when utility rates are at their highest.

This reduced need for cooling results in significant utility cost savings and source energy savings.

CG-PRC017H-EN 9

Application Considerations

Another advantage of an ice storage system is its ability to eliminate chiller over sizing. A “rightsized” chiller plant with ice storage operates more efficiently with smaller support equipment

while lowering the connected load and reducing operating costs. Best of all this system still provides a capacity safety factor and redundancy by building it into the ice storage capacity for practically no cost compared to over sized systems.

TheTrane air-cooled chiller is uniquely suited to low temperature applications like ice storage

because of the ambient relief experienced at night. Chiller ice making efficiencies are typically similar to or even better than standard cooling daytime efficiencies as a result of night-time drybulb ambient relief.

Standard smart control strategies for ice storage systems are another advantage of the CGAM chiller.The dual mode control functionality are integrated right into the chiller.TraneTracer building management systems can measure demand and receive pricing signals from the utility and decide when to use the stored cooling and when to use the chiller.

Partial Heat Recovery Operation

Partial heat recovery is designed to salvage a portion of the heat that is normally rejected to the atmosphere through the air-cooled condenser coil and put it to beneficial use.With the addition of a heat recovery cycle, heat removed from the building cooling load can be transferred to a preheat application. Keep in mind that the heat recovery cycle is only possible if a cooling load exists to act as a heat source.

To provide a heat recovery cycle, a supplemental heat exchanger is mounted in series to the air-

cooled condenser.The supplemental heat exchanger is piped into a preheat circuit. During the heat recovery cycle, the unit operates just as it does in the cooling-only mode except that a portion of the cooling load heat is rejected to the water heating circuit rather than to the air through the aircooled condenser. Water circulated through the heat recovery heat exchanger by the pumps absorbs cooling load heat from the compressed refrigerant gas discharged by the compressors.

The heated water is then used to satisfy heating requirements.

Partial heat recovery can be used in applications where hot water is needed for use in kitchens, lavatories, etc. It is comparatively smaller in size and its heating capacity is not controlled.The partial heat recovery heat exchanger cannot operate alone without a load on the chiller.

The partial heat recovery heat exchanger can get up to 157°F (69.4°C) leaving temperature. For

more information see the Performance Selection Program.

Unit Placement

SettingThe Unit

A base or foundation is not required if the selected unit location is level and strong enough to

support the unit’s operating weight (see “Weights” section of this catalog).

For a detailed discussion of base and foundation construction, refer to the sound engineering bulletin or the unit IOM. Manuals are available through the localTrane office.

HVAC equipment must be located to minimize sound and vibration transmission to the occupied spaces of the building structure it serves. If the equipment must be located in close proximity to a building, it should be placed next to an unoccupied space such as a storage room, mechanical room, etc. It is not recommended to locate the equipment near occupied, sound sensitive areas of the building or near windows. Locating the equipment away from structures will also prevent sound reflection, which can increase sound levels at property lines or other sensitive points.

10 CG-PRC017H-EN

Isolation and Sound Emission

Structurally transmitted sound can be reduced by elastomeric vibration eliminators. Elastomeric isolators are generally effective in reducing vibratory noise generated by compressors, and therefore, are recommended for sound sensitive installations. An acoustical engineer should always be consulted on critical applications.

Flexible electrical conduit

Concrete base

For maximum isolation effect, water lines and electrical conduit should also be isolated.Wall sleeves and rubber isolated piping hangers can be used to reduce the sound transmitted through water piping.To reduce the sound transmitted through electrical conduit, use flexible electrical conduit.

Local codes on sound emissions should always be considered. Since the environment in which a sound source is located affects sound pressure, unitplacement must be carefullyevaluated. Sound power levels for chillers are available on request.

Adequate clearance for evaporator and compressor servicing should be provided. Recommended

minimum space envelopes for servicing are located in the dimensional data section and can serve as a guideline for providing adequate clearance.The minimum space envelopes also allow for control panel door swing and routine maintenance requirements. Local code requirements may take precedence.

CG-PRC017H-EN 11

Application Considerations

Unit Location

General

Unobstructed flow of condenser air is essential to maintain chiller capacity and operating efficiency. When determining unit placement, careful consideration must be given to assure a sufficient flow of air across the condenser heat transfer surface.Two detrimental conditions are possible and must be avoided: warm air recirculation and coil starvation. Air recirculation occurs when discharge air from the condenser fans is recycled back to the condenser coil inlet. Coil starvation occurs when free airflow to the condenser is restricted.

Condenser coils and fan discharge must be kept free of snow or other obstructions to permit adequate airflow for satisfactory unit operation. Debris, trash, supplies, etc., should not be allowed to accumulate in the vicinity of the air-cooled chiller. Supply air movement may draw debris into the condenser coil, blocking spaces between coil fins and causing coil starvation.

Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity because of the higher head pressures associated with them.The air-cooled CGAM chiller offers an advantage over competitive equipment in these situations. Operation is minimally affected in many restricted air flow situations due to its advanced Adaptive Control™ microprocessor which has the ability to understand the operating environment of the chiller and adapt to it by first optimizing its performance and then staying on line through abnormal conditions. For example, high ambient temperatures combined with a restricted air flow situation will generally not cause the air-cooled model CGAMchiller to shut down. Otherchillers would typically shutdown on ahigh pressure nuisance cut-out in these conditions.

Cross winds, those perpendicular to the condenser, tend to aid efficient operation in warmer ambient conditions. However, they tend to be detrimental to operation in lower ambients due to the accompanying loss of adequate head pressure. Special consideration should be given to low ambient units. As a result, it is advisable to protect air-cooled chillers from continuous direct winds exceeding 10 mph (4.5 m/s) in low ambient conditions.

The recommended lateral clearances are depicted in the close spacing engineering bulletin

available from your local office.

Provide Sufficient Unit-to-Unit Clearance

Units should be separated from each other by sufficient distance to prevent warm air recirculation or coil starvation. Doubling the recommended single unit air-cooled chiller clearances will generally prove to be adequate.

Walled Enclosure Installations

When the unit is placed in an enclosure or small depression, the top of the surrounding walls

should be no higher than the top of the fans.The chiller should be completely open above the fan deck.There should be no roof or structure covering the top of the chiller. Ducting individual fans is not recommended.

Adaptive Controls

Adaptive Controls directly sense the control variables that govern the operation of the chiller:

evaporator pressure and condenser pressure.When any one of these variables approaches a limit condition when damage may occur to the unit or shutdown on a safety, Adaptive Controls takes corrective action to avoid shutdown and keep the chiller operating.This happens through combined actions of compressor and/or fan staging. Whenever possible, the chiller is allowed to continue making chilled water. This keeps cooling capacity available until the problem can be solved. Overall, the safety controls help keep the building or process running and out of trouble.

CG-PRC017H-EN 31

Controls

Stand-Alone Controls

Single chillers installed in applications without a building management system is simple to install and control: only a remote auto/stop for scheduling is required for unit operation. Signals from the chilled-water pump contactor auxiliary, or a flow switch, are wired to the chilled-water flow interlock. Signals froma timeclock or some other remote device arewired tothe external auto/stop input.

• Auto/Stop - A job-site provided contact closure turns the unit on and off.

• External Interlock - A job-site provided contact opening wired tothis input turns the unit off and requires a manual reset of the unit microcomputer.This closure is typically triggered by a jobsite provided system such as a fire alarm.

Time of Day Scheduling

Time of day scheduling allows the customer to perform simple chiller scheduling without the need

for a building automation system.

This feature allows the user to set ten events in a seven day time period. For each event the user

can specify an activation time and the days of the week the event is active.Any available setpoints can be specified for each event, such as the leaving chilled water temperature (standard) and the demand limit setpoint (optional if ordered).

Required features:

• Time of day scheduling (selectable option with chiller)

Additional options that if ordered may be incorporated into the scheduling:

• External chilled water setpoint, external demand limit setpoint

• Ice-making initiation

Hardwire Points

Microcomputer controls allow simple interface with other control systems, such as time clocks, building automation systems, and ice storage systems via hardwire points.This means you have the flexibility to meet job requirements while not having to learn a complicated control system.

Remote devices are wired from the control panel to provide auxiliary control to a building automation system. Inputs and outputs can be communicated via a typical 4–20 mA electrical signal, an equivalent 2–10 Vdc signal, or by utilizing contact closures.

This setup has the same features as a stand-alone water chiller, with the possibility of having

additional optional features:

• Ice making control

• External chilled water setpoint, external demand limit setpoint

• Chilled water temperature reset

• Programmable relays - available outputs are: alarm-latching, alarm-auto reset, general

alarm, warning, chiller limit mode, compressor running, andTracer control

Mechanical Specifications

General

Units are constructed of galvanized steel frame with galvanized steel panels and access doors. Component surfaces are finished with a powder-coated paint. Each unit ships with full operating charges of refrigerant and oil.

Compressor and Motor

The unit is equipped with two or more hermetic, direct-drive, 3600 rpm 60 Hz (3000 rpm 50 Hz)

suction gas-cooled scroll compressors.The simple design has only three major moving parts and a completely enclosed compression chamber which leads to increased efficiency. Overload protection is included.The compressor includes: centrifugal oil pump, oil level sight glass and oil charging valve. Each compressor will have compressor heaters installed and properly sized to minimize the amount of liquid refrigerant present in the oil sump during off cycles.

Unit-Mounted Starter

The control panel is designed per UL 1995.The starter is an across-the-line configuration, factory-

mounted and fully pre-wired to the compressor motor and control panel. A factory-installed, factory-wired 820 VA control power transformer provides all unit control power (120 Vac secondary) andTrane CH530 module power (24 Vac secondary). Power line connection type is standard with a terminal block.

Evaporator

Braze plate heat exchanger is made of stainless steel with copper as the braze material. It is designed to withstand a refrigerant side working pressure of 430 psig (29.6 bars) and a waterside working pressure of 150 psig (10.5 bars). Evaporator is tested at 1.1 times maximum allowable refrigerant side working pressure and 1.5 times maximum allowable water side working pressure. It has one water pass. Immersion heaters protect the evaporator to an ambient of -20°F (-29°C).

The evaporator is covered with factory-installed 0.75 inch (19.05 mm)Armaflex II or equal (k=0.28)

insulation. Foam insulation is used on the suction line. Water pipe extensions with insulation go from the evaporator to the edge of the unit.

Condenser

Air-cooled condenser coils have aluminum fins mechanically bonded to internally-finned copper

tubing.The condenser coil has an integral subcooling circuit.The maximum allowable working pressure of the condenser is 650 psig (44.8 bars). Condensers are factory proof and leak tested at 715 psig (49.3 bars).

Direct-drive vertical discharge condenser fans are balanced.Three-phase condenser fan motors with permanently lubricated ball bearings and external thermal overload protection are provided.

Units start and operate from 0°F to 125°F (-18°C to 52°C) for wide ambient. Wide ambient allows operation down to 0°F which is accomplishedby a variable speed fan on each circuit thatmodulates to maintain system differential pressure.

Refrigerant Circuit and Capacity Modulation

The 20-35 ton units have single refrigerant circuits.The 40-130 ton units have dual refrigerant circuits. Each refrigerant circuit hasTrane scroll compressors piped in parallel with a passive oil management system. A passive oil management system maintains proper oil levels within compressors and has no moving parts. Each refrigerant circuit includes filter drier, electronic expansion valve, and liquid line and discharge service valves.

CG-PRC017H-EN 59

Mechanical Specifications

Capacity modulation is achieved by turning compressors on and off. The 20-35 ton units have two capacity stages. The 40-120 ton units have four capacity stages.The 130 ton unit has six capacity stages.

Unit Controls (Trane CH530)

The microprocessor-based control panel is factory-installed and factory-tested.The control system

is powered by apre-wired controlpower transformer, and will turn onand off compressors to meet the load. Microprocessor-based chilled water reset based on return water is standard.

TheTrane CH530 microprocessor automatically acts to prevent unit shutdown due to abnormal

operating conditions associated with low evaporator refrigerant temperatureand high condensing temperature. If an abnormal operating condition continues and the protective limit is reached, the machine will shut down.

The panel includes machine protection for the following conditions:

• Low evaporator refrigerant temperature and pressure

• High condenser refrigerant pressure

• Critical sensor or detection circuit faults

• High compressor discharge temperature (with low temp evaporator)

• Lost communication between modules

• Electrical distribution faults: phase loss, phase reversal or over temperature protection

• External and local emergency stop

• Loss of evaporator water flow

When a fault is detected, the control system conducts more than 100 diagnostic checks and displays

results.The display will identify the fault, indicate date, time, and operating mode at time of occurrence, and provide type of reset required and a help message.

Clear Language Display Panel

Factory-mounted to the control panel door, the operator interface has an LCD touch-screen display for operator input and information output.This interface provides access to the following information: evaporator report, condenser report, compressor report,ASHRAE Guideline 3 report, operator settings, service settings, service tests, and diagnostics.All diagnosticsand messagesare displayed in “clear language.”

Data contained in available reports includes:

• Water and air temperatures

• Refrigerant pressures and temperatures

• Flow switch status

• EXV position

• Compressor starts and run-time

All necessary settings and setpoints are programmed into the microprocessor-based controller via

the operator interface.The controller is capable of receiving signals simultaneously from a variety of control sources, in any combination, and priority order of control sources can be programmed.

The control source with priority determines active setpoints via the signal it sends to the control

panel. Control sources may be:

• Local operator interface (standard)

• Hard-wired 4-20 mA or 2-10 Vdc signal from an external source (interface optional; control source not supplied)

• Time of day scheduling (optional capability available from local operator interface)

60 CG-PRC017H-EN

• LonTalk®LCI-C (interface optional; control source not supplied)

• BACNet®(interface optional; control source not supplied)

• TraneTracer Summit™ system (interface optional; control source not supplied)

Application Options

Ice-Making with Hardwired Interface

Unit controls are factory set to handle ice-making for thermal storage application. An additional temperature sensor, at the compressor discharge, enables full load operation of the chiller with entering evaporator fluid temperature between 20°F (-7°C) and 65°F (18°C) with glycol.

High Ambient

The unit starts and operates from 32°F to 125°F (0°C to 52°C).

Mechanical Specifications

Low-Temperature Processing

An additional temperature sensor, at the compressor discharge, enables leaving evaporator fluid

temperature between 10°F (-12.2°C) and 42°F (5.5°C) with glycol.

Partial Heat Recovery with Fan Control

A supplemental brazed plate heat exchanger is mounted in series to the condenser coil.

Connecting piping and inlet and outlet water sensors are included. CH530 controls display heat recovery inlet and outlet water temperatures and controls the fans.The heat rejection to the partial heat recovery heat exchanger is not controlled. Flow and temperature variations through the partial heat recovery heat exchanger will vary.The partial heat recovery heat exchanger is typically used to preheat water before it enters a boiler or other water heating process.

Dual
