General Description

Daikin McQuay Pathfinder™ air-cooled chillers are complete, self-contained chillers that include the latest in engineered components arranged to provide a compact and efficient unit. Each unit is completely assembled, factory wired, evacuated, charged, tested and comes complete and ready for installation. Each of two circuits consists of an air-cooled condenser section with an integral subcooler section, a semi-hermetic, single-screw compressor with starter, a multi-circuit, shelland-tube, direct expansion evaporator, an economizer and complete refrigerant piping. Each compressor has an independent refrigeration circuit. Liquid line components included are a manual liquid line shutoff valve, charging port, filter-drier, sight-glass/moisture indicator, and electronic expansion valve. A combination discharge check and shutoff valve is included and a compressor suction shutoff valve is optional. Other features include compressor heaters, evaporator heaters for freeze protection, automatic, one-time pumpdown of each refrigerant circuit upon circuit shutdown, and an advanced fully integrated microprocessor control system.

Introduction

A high ambient option is required for operation in ambient temperatures above 100F (37.8C) and up to 125F (51.7C) and when the VFD low ambient option is selected.

Information on the operation of the unit MicroTech controller is in the OM 998 manual.

Inspection

When the equipment is received, carefully check all items against the bill of lading to verify for a complete shipment. Check all units for damage upon arrival. All shipping damage must be reported to the carrier and a claim must be filed with the carrier. Check the unit’s serial plate before unloading the unit to be sure that it agrees with the power supply available. Physical damage to a unit after shipment is not McQuay International’s responsibility.

Note: Unit shipping and operating weights are shown in the Physical Data Tables beginning on page 15.

Installation and Startup

Installation and maintenance are to be performed only by qualified personnel who are familiar with local codes and

regulations, and experienced with this type of equipment.

WARNING

Sharp edges and coil surfaces are a potential injury hazard. Avoid contact with them.

Start-up by McQuay Factory Service is included on all Pathfinder units sold for installation within the U.S. and Canada and must be performed by them to initiate the standard Limited Product Warranty. Start-up by any party other than McQuay Factory Service or a McQuay Authorized Service Representative will void the Limited Product Warranty. Twoweek prior notification of start-up is required. The contractor should obtain a copy of the Start-up Scheduled Request Form from the sales representative or from the nearest McQuay

Factory Service office.

WARNING

Escaping refrigerant can displace air and cause suffocation. Immediately evacuate and ventilate the equipment area. If the unit is damaged, follow Environmental Protection Agency (EPA) requirements. Do not expose sparks, arcing equipment, open flame or other ignition source to the refrigerant.

For pad-mounted units, it is recommended that the unit be raised a few inches with suitable supports such as neoprene waffle vibration pads, located at least under the mounting locations. This will allow water to drain from under the unit and facilitate cleaning under it.

Figure 2: Required Lifting Method

Handling

DANGER

Improper lifting or moving of a unit can result in property damage, severe personal injury or death. Follow rigging and moving instructions carefully.

Avoid rough handling shock due to impact or dropping the unit. Do not push or pull the unit. Never allow any part of the unit to fall during unloading or moving, as this can result in serious damage.

To lift the unit, lifting tabs with 3" (76 mm) diameter holes are provided on the base of the unit. All lifting holes must be used when lifting the unit. Spreader bars and cables should be arranged to prevent damage to the condenser coils or unit cabinet (see Figure 2).

Location

Locate the unit carefully to provide proper airflow to the condenser. (SeeFigure 4, page 5 for required clearances.)Using less clearance than shown in Figure 4can cause discharge air recirculation to the condenser and could have a significant detrimental effect on unit performance.

Due to the shape of the condenser coils on the Pathfinder chillers, it is recommended that the unit be oriented so that prevailing winds blow parallel to the unit length, thus minimizing the wind effect on condensing pressure and performance. If low ambient temperature operation is expected, optional louvers should be installed if the unit has no protection against prevailing winds.

1. Unit with 8 lifting points illustrated above; the number of

condenser sections, fans, and lifting points can vary from this diagram.see lifting/mounting drawings beginning on page page 43 to identfy the number of lifting points for a specific unit.

2. All rigging points must be used. See weights at lifting

points beginning on page 39 for each specific size unit.

3. Crosswise and lengthwise spreader bars must be used to

avoid damage to unit.

Service Access

Compressors, filter-driers, and manual liquid line shutoff valves are accessible on each side or end of the unit. The evaporator heater is located on the barrel.

The control panels are located on the end of the chiller. The left-hand control box contains the unit and circuit microprocessors as well as transformers, fuses and terminal. The right-hand panel contains a circuit breaker. A minimum of four feet of clearance is required in front of the panels.

Restricted Air Flow

The clearances required for design operation of Pathfinder aircooled chillers are described in the previous section. Occasionally, these clearances cannot be maintained due to site restrictions such as units being too close together or a fence or wall restricting airflow, or both. Pathfinder chillers have several features that may help mitigate the penalties attributable to restricted airflow.

"The condenser section is "W" shaped, as shown below. This allows inlet air for these coils to come in from both sides and the bottom. All the coils in one "V" section serve one compressor. Each compressor has its own independent refrigerant circuit.

"The MicroTech III control is proactive in response to "offdesign conditions". In the case of single or compounded influences restricting airflow to the unit, the microprocessor will act to keep the unit running (at reduced capacity), rather than allowing a shut-off on high discharge pressure.

Case 1: Building or Wall on One Side of One Unit

The existence of a screening wall or the wall of a building in close proximity to an air-cooled chiller is common in both rooftop and ground level applications. Hot air recirculation on the coils adjoining the wall will increase compressor discharge pressure, decreasing capacity and increasing power consumption.

When close to a wall, it is desirable to place chillers on the north or east side of them. It is also desirable to have prevailing winds blowing parallel to the unit's long axis. The worst case is to have wind blowing hot discharge air into the wall.

Case 2: Two Units Side By Side

Two or more units sited side by side are common. If spaced closer than 12 feet (3.7 meters) it is necessary to adjust the performance of each unit; circuits adjoining each other are affected. If one of the two units also has a wall adjoining it, see Case 1. Add the two adjustment factors together and apply to the unit located between the wall and the other unit.

Mounting units end to end will not necessitate adjusting performance.

Do not use pit or solid wall surrounds where the ambient air temperature exceeds 105F (40C).

Figure 8: Two Units Side by Side - Adjustment Factors

Case 3: Three or More Units Side By Side

When three or more units are side by side, the outside chillers (1 and 3 in this case) are influenced by the middle unit only on their inside circuits. Their adjustment factors will be the same as Case 2. All inside units (only number 2 in this case) are influenced on both sides and must be adjusted by the factors shown below.

Case 4: Open Screening Walls

Decorative screening walls are often used to help conceal a unit either on grade or on a rooftop. Design these walls such that the combination of their open area and distance from the unit do not require performance adjustment. It is assumed that the wall height is equal to or less than the unit height when mounted on its base support. This is usually satisfactory for concealment. If the wall height is greater than the unit height, see Case 5, Pit Installation.

The distance from the sides of the unit to the side walls must be sufficient for service, such as opening control panel doors.

If each side wall is a different distance from the unit, the distances can be averaged providing either wall is not less than 8 feet (2.4 meters) from the unit. For example, do not average 4 feet and 20 feet to equal 12 feet (1 meter and 5 meters to equal 3 meters).

Figure 10: Open Screening Walls - Adjustment Factors

Case 5, Pit/Solid Wall Installation

Pit installations can cause operating problems. Use care if they are to be used on an installation. Recirculation and restriction can both occur. A solid wall surrounding a unit is substantially the same as a pit and the data presented here should be used.

Steel grating is sometimes used to cover a pit to prevent accidental falls or trips into the pit. The grating material and installation design must be strong enough to prevent such accidents, yet provide abundant open area or serious recirculation problems will occur. Have any pit installation reviewed by the McQuay sales representative prior to installation to make sure it has sufficient air-flow characteristics. The installation design engineer must approve the work to avoid an unreasonable risk of accident.

Installation and Startup

Chilled Water

It is recommended that the chilled water pumps' starters be wired to, and controlled by, the chiller's microprocessor. The controller will energize the pump whenever at least one circuit on the chiller is enabled to run, whether there is a call for cooling or not. The control will also start the pump when freezing temperatures are approached. Wiring connection points are shown in Figure 62, page 78.

Water Piping

Due to the variety of piping practices, follow the recommendations of local authorities. They can supply the installer with the proper building and safety codes required for a proper installation.

Design the piping with a minimum number of bends and changes in elevation to keep system cost down and performance up. It should contain:

1 Vibration eliminators to reduce vibration and noise

transmission to the building.

2 Shutoff valves to isolate the unit from the piping system

during unit servicing.

3 Manual or automatic air-vent valves at the high points of

the system and drains at the low parts in the system. The evaporator should not be the highest point in the piping system.

4 Some means of maintaining adequate system water

pressure (i.e., expansion tank or regulating valve).

5 Water temperature and pressure indicators located at the

evaporator inlet and outlet to aid in unit servicing. Any connections should be made prior to filling the system with water.

6 A strainer to remove foreign matter from the water

before it enters the pump. Place the strainer far enough upstream to prevent cavitation at the pump inlet (consult pump manufacturer for recommendations). The use of a strainer will prolong pump life and help maintain high system performance levels. Note: A 20-mesh strainer must also be placed in the supply water line just prior to the inlet of the evaporator. This will aid in preventing foreign material from entering the evaporator and causing damage or decreasing its performance. Care must also be exercised if welding pipe or flanges to the evaporator connections to prevent any weld slag from entering the vessel.

7 Any water piping to the unit must be protected to prevent

freeze-up if below freezing temperatures are expected.

8 If the unit is used as a replacement chiller on a

previously existing piping system, flush the system thoroughly prior to unit installation. Perform regular chilled water analysis and chemical water treatment immediately at equipment start-up.

9 In the event glycol is added to the water system as a late

addition for freeze protection, recognize that the refrigerant suction pressure will be lower, cooling performance less, and water side pressure drop greater. If the percentage of glycol is large, or if propylene is employed in lieu of ethylene glycol, the added pressure drop and loss of performance could be substantial.

10 For ice making or low temperature glycol operation, a

different freezestat pressure value is usually required. The freezestat setting can be manually changed through the MicroTech III controller.

Make a preliminary leak check prior to insulating the water piping and filling the system.

Include a vapor barrier with the piping insulation to prevent moisture condensation and possible damage to the building structure. It is important to have the vapor barrier on the outside of the insulation to prevent condensation within the insulation on the cold surface of the pipe.

Optional Inlet Strainer

An inlet water strainer kit is available as a shipped-loose option, sized per Tab le 2 and with the pressure drop shown in

Figure 12. The kit is field installed and consists of:

• Y-type 40% open area strainer with 304 stainless steel perforated basket, Victaulic pipe connections and strainer cap

• Extension pipe with two Schrader fittings that can be used for a pressure gauge and thermal dispersion flow switch. The pipe provides sufficient clearance from the evaporator for strainer basket removal.

• ½-inch blowdown valve

• Two Victaulic clamps

Figure 12: Strainer Pressure Drop

Installing Optional Inlet Strainer

The extension pipe is located adjacent to the evaporator with the strainer then mounted to it. The strainer must be mounted per manufacturer's instruction with the arrows in the direction of flow; inlet and outlet are noted along with the arrows.

Use one Victaulic clamp to mount the extension pipe to the evaporator and the second to mount the strainer to the pipe. The clamps to mount the field piping to the strainer are field supplied. The piping and strainer must be supported to prevent any stress on the evaporator nozzle.

The extension pipe has two Schrader fittings that can be used as desired, frequently for mounting the optional McQuay thermal dispersion flow switch and a water pressure gauge. The ball valve can be installed in the strainer basket cover as a blow-down valve.

System Water Volume

All chilled water systems need adequate time to recognize a load change, respond to that load change and stabilize, without undesirable short cycling of the compressors or loss of control. In air conditioning systems, the potential for short cycling usually exists when the building load falls below the minimum chiller plant capacity or on close-coupled systems with very small water volumes.

Some of the things the designer should consider when looking at water volume are the minimum cooling load, the minimum chiller plant capacity during the low load period and the desired cycle time for the compressors.

Assuming that there are no sudden load changes and that the chiller plant has reasonable turndown, a rule of thumb of "gallons of water volume equal to two to three times the chilled water gpm flow rate" is often used.

A properly designed storage tank should be added if the system components do not provide sufficient water volume.

Variable Speed Pumping

Variable water flow involves reducing the water flow through the evaporator as the load decreases. McQuay chillers are designed for this duty, provided that the rate of change in water flow is slow, and the minimum and maximum flow rates for the vessel are not exceeded.

The recommended maximum change in water flow is 10 percent of the change per minute. For example, if the maximum (design) flow is 200 gpm and the flow is reduced to a minimum of 140 gpm, the change in flow is 60 gpm, so the maximum change per minute would be 10% of 60, or 6 gpm per minute. It would take ten minutes to change the flow through the entire range.

The water flow through the vessel must remain between the minimum and maximum values listed on page 19. If flow drops below the minimum allowable, large reductions in heat transfer can occur. If the flow exceeds the maximum rate, excessive pressure drop and tube erosion can occur.

Evaporator Freeze Protection

Pathfinder chillers are equipped with thermostatically controlled evaporator heaters that help protect against freezeup down to -20°F (-28°C). For additional protection, at least one of the followingprocedures should be used during periods of sub-freezing temperatures:

1 Adding of a concentration of a glycol anti-freeze with a

freeze point 10°F. below the lowest expected temperature. This will result in decreased capacity and increased pressure drop.

Note: Do not use automotive grade antifreezes as they contain

inhibitors harmful to chilled water systems. Use only glycols specifically designated for use in building cooling systems.

Draining the water from outdoor equipment and piping and blowing the chiller tubes dry from the chiller. Do not energize the chiller heater when water is drained from the vessel.

3 Providing operation of the chilled water pump,

circulating water through the chilled water system and through the evaporator

Note: The heaters come from the factory connected to the

control power circuit. The control power can be rewired in the field to a separate 115V supply (do not wire directly to the heater). See the field wiring diagram on page 78. If this is done, it should power the entire control circuit. Mark the disconnect switch clearly to avoid accidental deactivation of the heater during freezing temperatures. Exposed chilled water piping also requires protection. If the evaporator is drained for winter freeze protection, the

Flow Switch

A flow switch must be included in the chilled water system to prove that there is adequate water flow before the unit can start. It also serves to shut down the unit in the event that water flow is interrupted in order to guard against evaporator freezeup.

A factory-mounted, solid state, thermal dispersion flow switch is available as an option. A field-installed version is also available as a kit (Accessory part number 332688401).

A paddle-type flow switch for field mounting and wiring is also available as a kit (Accessory part number 017503300). It is adaptable to pipe sizes from 1" (25mm) to 8" (203mm).

Certain minimum flow rates are required to close the switch and are listed in Table 4. Installation should be as shown in

Figure 13.

Electrical connections in the unit control center should be made at terminals 60 and 67 from switch terminals Y and R. The normally open contacts of the flow switch should be wired between these two terminals. Flow switch contact quality must be suitable for 24 VAC, low current (16ma). Flow switch wire must be in separate conduit from any high voltage conductors (115 VAC and higher) and have an insulation rating of 600 volts.

All packaged units are designed for use with R-134a and are shipped with a full operating charge. The operating charge for each unit is shown in the Physical Data Tables beginning on

page 15.

Glycol Solutions

When using glycol anti-freeze solutions, the chiller's capacity, glycol solution flow rate, and pressure drop through the evaporator can be calculated using the following formulas and tables.

Note: The procedure below does not specify the type of glycol. Use the derate factors found in Table 5 or Table 6 forcorrections when using glycol.

1 Capacity - Cooling capacity is reduced from that with

plain water. To find the reduced value, multiply the chiller’s water system tonnage by the capacity correction factor to find the chiller’s capacity when using glycol.

2 Flow - To determine flow (or Delta-T) knowing Delta-T

(or flow) and capacity:

3 Pressure drop - To determine pressure drop through the

evaporator when using glycol, enter the water pressure drop curve at the water flow rate. Multiply the water pressure drop found there by the "PD" factor to obtain corrected glycol pressure drop.

4 Power - To determine glycol system kW, multiply the

water system kW by the factor designated "Power".

Note: Do not use automotive grade antifreeze. Industrial grade glycols

must be used. Automotive antifreeze contains inhibitors that will cause plating on the copper tubes within the chiller evaporator. The type and handling of glycol used must be consistent with local codes.

Performance Adjustment Factors

Ethylene and Propylene Glycol Factors

AWS chiller units are designed to operate with leaving chilled fluid temperatures of 20.0°F to 60.0°F (-6.7°C to 15.6°C). Consult the local McQuay sales office for performance outside these temperatures. Leaving chilled fluid temperatures below 40°F (4.4°C) result in evaporating temperatures at or below the freezing point of water and a glycol solution is required. MicroTech III control inhibits compressor unloading at leaving fluid temperatures below 30°F (-1°C). McQuay also recommends optional double insulation, and the system designer should determine its necessity. The use of glycol will reduce the performance of the unit depending on its concentration. Take this into consideration during initial system design. On glycol applications, the supplier typically recommends that a minimum of 25% solution by weight be used for protection against corrosion, or additional inhibitors will be

required.

Isolator Locations and Kit Numbers

Transfer the unit as indicated under Handling on page 4. In all cases, set the unit in place and level with a spirit level. When spring-type isolators are required, install springs running under the main unit supports.

The unit should be set initially on shims or blocks at the listed spring free height. When all piping, wiring, flushing, charging, etc., is completed, the springs are adjusted upward to loosen the blocks or shims that are then removed.

A rubber anti-skid pad should be used under isolators if holddown bolts are not used.

Installation of spring isolators requires flexible piping connections and at least three feet of flexible electrical conduit to avoid straining the piping and transmitting vibration and noise.
