Features and Benefits

EfficiencyWHR-EW Water-Cooled and WHR-EA Air-Cooled, (depending on remote condenser selection) meetASHRAE 90-1 efficiency levels - the world’s standard for chiller efficiency.

The “E” vintage WHR-EA reciprocating chillers offer some of the highest operating efficienciesavailable today through the use of highly efficient components and efficiency oriented packaging.

Operating economy at reduced load is increased by operating each refrigerant circuit partiallyunloaded, rather than one circuit off and the other circuit fully loaded. At unloaded conditions eachcompressor will operate at lower compression ratios with substantial power savings.

Optional steps of capacity reduction are accomplished by the most efficient method of cylinderunloading in the industry today.

To McQuay, operating economy means more than just energy efficiency. The WHR chillers reduceoperating costs not only through energy efficiency, but by offering high unit reliability, easyserviceability, full factory testing and the backing of a factory trained sales, service and partsorganization.

FlexibilityThe WHR chillers come in 25 sizes between 17 and 210 nominal tons (60 and 710 kW). The smallcapacity increments provide a selection that will closely match the required job capacity.

The WHR water chillers come completely factory assembled, piped, wired, and shipped in one piece;ready for water piping and wiring connections. The EA remote condenser models are ready for fieldpiping to the remote condenser. Single main supply power terminal block can be supplied by one fieldinstalled main supply power disconnect switch.

Many optional features can been added to fit your needs. A unit mounted non-fused disconnectswitch eliminates the need for a field installed disconnect. Phase failure/reversal protection, highreturn water unloading, and acoustical sound enclosures around compressor are all optional featuresthat can be factory installed.

ReliabilityThe McQuay WHR chillers use the most advanced and efficient reciprocating compressors in theindustry, the Copeland DISCUS valve compressors. These heavy-duty, industrial quality, semi-hermetic compressors are designed for R 22 or R-134a.

All WHR chillers are factory run tested to assure unit functionality. All safety and operating controlsare checked and calibrated. Chillers for remote condensers are connected to slave condensers fortesting purposes. This extensive testing assures trouble-free start-ups.

To protect the unit from abnormal operating conditions, a complete set of safety controls for eachcircuit is used. Safety controls include compressor crankcase heater(s), freeze protectionpressurestats (manual reset), oil switches (manual rest), high pressure safety switches (manual reset),and compressor motor overload protectors. Standard operating controls include time delay relays for20-second sequence starting of compressors, manual pumpdown switches, low pressure controls,compressor lead-lag switches (WHR-040EW-210EW) and chilled water temperature controller. Allcontrols and wiring are completely factory labeled for ease of service.


ServiceabilitySemi-hermetic, 1750 rpm induction type motors are employed. The motors are refrigerant gas cooled.A finned motor housing helps dissipate motor heat. Solid-state modules in the motor terminal boxrespond to temperature sensors imbedded in all three motor windings to provide inherent thermaloverload protection for all run and start conditions.

Serviceable compressors offer reducedmaintenance costs because if problemsdevelop with components such as oilpumps, unloaders, and pistons, theycan be serviced in the field withoutreplacing the compressor. Both suctionand discharge service valves areprovided to allow isolation of thecompressor from the refrigerant circuit.

All multiple compressor units utilizetwo independent refrigerant circuits.Dual refrigerant circuits permitshutdown and routine maintenance andservice of one circuit while the secondcircuit maintains system operationwhere two or more compressors aresupplied.

RefrigerantsModels WHR 017 through WHR 210 utilize R-22 as the standard refrigerant. Models WHR 040through WHR 210 can be furnished with R-134a refrigerant.

Full factory testingExtensive quality control checks and individual performance tests assure that the units will meet therequirements of the application and start-up and perform reliably. EA remote condenser models areshipped with a holding charge of refrigerant, EW water-cooled units are shipped with a completeoperating charge.

Each unit is pressure tested, evacuated and charged with refrigerant for test purposes. Extensivequality control checks and individual unit performance tests, at full load, ensure that each control isproperly adjusted and operates correctly. EA remote condenser models are connected to factory slavecondensers for testing. Each unit is then rechecked for refrigerant leakage.

Code ApprovalsAll WHRhb units are constructed and/or rated with the latest ANSI/ASHRAE 15 Safety Code,National Electrical Code and ASME Boiler and Pressure Vessel Code. All models are ETL approved orcETL listed.


Design Advantages

Unit ArrangementsThe McQuay water chillers are completely factory assembled, piped, wired and shipped in one piece,ready for field connection of refrigerant (EA models) and water piping. Each unit consists of motorcompressors, insulated DX cooler and centralized electrical control panel containing all necessarysafety and operating controls, and compressor starting controls. Arrangement “EW” units comecomplete with water-cooled condensers with integral subcooler circuits. Arrangement “EA” units areprovided without condensers to allow for remote installation of air-cooled or evaporative condensingequipment.

Compressors WHR chillers use Copeland DISCUS semi-hermetic compressors. These compressors are designedfor R 22 and R-134a.

Semi-hermetic, 1750 rpm induction type motors are used. The motors are refrigerant gas cooled. Solid-state modules in the motor terminal box respond to temperature sensors imbedded in all three motorwindings, providing inherent thermal overload protection for all run and start conditions.

The compressor housing is constructed from close grained, high nickel content, alloy cast-iron withno bolted joint between the motor and compressor. The housing includes a cast-iron cylinder headand stator cover, and a crankcase oil sightglass. A suction strainer built into the compressor in the gasstream between the suction service valve and the motor, filters out foreign and abrasive particles. Aninternal relief valve relieves discharge pressure to the suction side for safety protection at highcompression ratios as required by ANSI/ASHRAE 15 Safety Code.

Main bearings are solid cast bronze insert type with oversized bearing area resulting in ultra-lowbearing loading.

The crankshaft is die-forged, high strength iron alloy with integral counterweights, statically anddynamically balanced for smooth operation.

Connecting rods are lightweight aluminum with integral bearing surfaces on the crankshaft and pistonends. Pistons are close grain cast iron with oil and compression rings. Piston pins are full floatingtype for long life.

Compressors have a forced-feed lubrication system with positive oil displacement, a reversible oilpump, and an operating oil charge. The pump feeds oil through rifle-drilled passages in the crankshaftto all bearing surfaces. Magnetic plugs trap particles that enter the crankcase. The oil supply filtersthrough a large area oil strainer. During start-up, a crankcase heater minimizes oil being diluted byrefrigerant.

Factory Installed Liquid Line Components Each refrigerant circuit has a filter-drier, liquid line sightglass/moisture indicator, solenoid valve,manual liquid line shutoff valve and thermal expansion valve.

Short Circuit Protection (WHR 017 through 030, WHR 095 through 210)

Each compressor is individually protected against short circuit and locked rotor conditions by factoryinstalled circuit breakers. Separate fusing protects the control circuit. WHR-040 through 090 can havecircuit breakers factory installed as an option.


Part Load Efficiencies Part load efficiencies and Integrated Part Load Values (IPLV) for EW units are calculated according tothe requirements of the latest ARI Standard 550/590-98 and meet or exceed ASHRAE EfficiencyStandard 90.1. Since most air conditioning systems operate at less than design full load a majority ofthe time, IPLV is an excellent method for comparing chillers' efficiencies.

Noise All McQuay WHR chillers are equipped with hot gas discharge line mufflers in each refrigerant circuitto reduce the overall sound levels. An optional insulated acoustical compressor enclosure to furtherreduce sound levels is also available for most units. Sound level ratings are contained in the SoundRating section of this manual.

Unit Base Designed for easy handling, the units are mounted on a compact, rugged formed steel base. Isolatormounting holes are provided.

Electrical Control Center Shipped with all operating and safety controls and motor starting equipment factory wired,operationally tested, and ready for operation. All controls are centrally located in a hinged controlcenter with keylocked doors.

Part-winding starters are standard on 208/230 volt applications and available as a special on 460/575volts. Across-the-line starters are standard on 380/460/575 volts.

A five-minute, solid-state lockout timer is provided to delay compressor restart after safety cutout orpower interruption, or under irregular cooling load demands. A lead lag switch is standard on all units(WHR 040 – WHR 210) not incorporating the single circuit hot gas bypass option.

Evaporator The evaporator is a direct expansion, shell-and-tube type with water flowing in the baffled shell sideand refrigerant flowing through the tubes.

The evaporator is constructed with a carbon steel shell and seamless high efficiency copper tubes,roller expanded into heavy carbon steel tube sheets. Water baffles are polypropylene to resistcorrosion.

Refrigerant heads are carbon steel with multi-pass baffles to ensure oil return and are removable topermit access to the tubes from either end. For water removal, 3/8" (10mm) vent and drain plugs areprovided on the top and bottom of the shell. Two 1/2” (12.7mm) couplings on each water nozzle allowfor easy field installation of sensor equipment.

The evaporator is wrapped with 3/4” (19.1mm) thick vinyl nitrate polymer sheet insulation. Theinsulation has a K factor of 0.28 at 75°F (24°C). The insulation is fitted and cemented in place, thenpainted with a resilient vinyl base paint to resist cracking.

The tube side maximum working pressure is 225 psig (1552kPa). The waterside working pressure is 175psig (1206kPa). All evaporators are designed, constructed, inspected and stamped according to therequirements of the ASME Boiler and Pressure Vessel Code.


Water-Cooled Condensers All water-cooled condensers are cleanable shell and tube type with water in the tubes and refrigerantin the shell. Each condenser is capable of holding the circuit pumpdown capacity. Independentcondensers serve the dual refrigerant circuits.

Each condenser is constructed with a carbon steel shell and seamless integrally finned high efficiencycopper tubes roller expanded into steel tubesheets. Water heads have vent and drain connectionsand are removable. Also included is a liquid shutoff valve, purge valve, 450 psi (3104 kPa) relief valveper ANSI/ASHRAE Pressure Vessel Code, Section VIII.

Optional MicroTech Chiller ControllerWHR-040 – 210 Only

The MicroTech reciprocating chiller controller surpasses all other microprocessor-based chillercontrol systems available today. This powerful, user-friendly control system provides the flexibilityand performance needed for a stand-alone unit as well as multiple units tied into a network system.

MicroTech’s state-of-the-art design will not only permit your chiller to run more efficiently, but willalso simplify troubleshooting if a system failure occurs. Every MicroTech controller is programmedand tested prior to shipment to ensure a trouble-free start-up.

Condenser fan control (Model EA)Control of condenser fans is available through the MicroTech controller. The control stepscondenser fans or groups of fans based on discharge pressure. Field wiring is required betweenthe chiller and the remote condenser.


Operator-friendlyThe 12-key, touch-sensitive, membrane keypad and 32-character display makes the MicroTechsystem especially user-friendly. Inch-pound or SI units are optionally available.

The MicroTech menu structure is separated into three distinct categories, which provide theoperator or service technician with a full description of current unit status, control parameters, andalarms. Security protection prevents unauthorized changing of the setpoints and controlparameters.

MicroTech continuously performs self-diagnostic checks, monitoring all system temperatures,pressures and safeties, and will automatically shutdown a compressor, a refrigerant circuit of theentire unit should a fault occur. The cause of the shutdown will be retained in memory and can beeasily displayed in plain English or metric units for operator review. The MicroTech chillercontroller can also retain and display the time the fault occurred and the operating conditions thatwere present at the time of the fault, which is an extremely useful feature for troubleshooting. Inaddition to displaying alarm diagnostics, the MicroTech chiller controller also provides the operatorwith a warning of pre-alarm conditions.

Ice storageThe MicroTech control easily changes the leaving fluid setpoint via a remote signal to thecontroller. The feature enables selection of chilled water or ice storage mode.

Enhanced chiller operating efficienciesThe MicroTech chiller controller offers many features to improve the operating efficiency of thereciprocating chiller. In addition to monitoring water temperature and air temperatures, refrigeranttemperatures and pressures, and unit amperage, MicroTech also offers the following energy savingfeatures:

Programmable setpoints

The MicroTech chiller controller offers precise digital settings of the leaving chilled watertemperature setpoint and all other control parameters. This is extremely important in the setting ofsafeties such as low leaving water temperature cutout, high pressure cutout, suction pressurecutout, and freeze protection.

Compressor soft loading

Soft loading limits the number of cooling stages to prevent unnecessary electrical demand andpossible overshoot of the leaving chilled water temperature setpoint.

Demand limit control

Based on a 4-20mA DC signal, the controller will determine the maximum number of stages permittedto operate, preventing additional demand charges during high usage periods.


Automatic circuit lead-lag

With the keypad, the operator can manually select either refrigerant circuit for the lead position orthe controller will automatically select the lead circuit based on the circuit with the fewest operatinghours.

Time clock, daily and holiday start/stop control

The operator can program daily start/stop schedules including weekends and up to fourteenseparate holidays without the need of an external time clock or EMS interface. If desired, anexternal time clock can be used instead of the internal schedule.

Chilled water pump control

There is no need for an external time clock or EMS interface to control the pump start/stopoperation. The MicroTech chiller controller can accomplish this through a digital output. If analarm shuts down the chiller, the chilled water pump will remain on, providing any remaining coolingto the loads.

Optional Network Master PanelThe MicroTech Network Master Panel (NMP) allows multiple reciprocating chiller controllers to beincorporated into a building-wide network with other MicroTech units and auxiliary controllers. Inconjunction with a personal computer, it provides the building operator with the capability toperform advanced equipment control and monitoring from a central or remote location. Thefollowing features are provided by the optional NMP:

• Remote unit monitoring• Advanced scheduling features• Advanced alarm management features• Global operator override• Global unit shutdown input• Demand metering• Historical electrical data logging

Optional Remote Monitoring and Sequence PanelOne to three reciprocating chiller controllers can be incorporated into a network with the MicroTechremote monitoring and sequencing (RMS) panel. The optional RMS panel provides the followingfeatures:

• Remote chiller monitoring (up to 3)• Automatic or manual chiller sequencing• Automatic or manual lead-lag designation• Common chiller scheduling• Optimal start control• Chilled water reset by outdoor air temperature or external 4-20 mA signal• Chiller run time totalization by month, current year, and prior year• Cooling degree-day totalization by month, current year, and prior year

The RMS panel is equipped with a keypad/display that is identical to the chiller controller’skeypad/display. With a special keystroke combination, the RMS keypad/display can be interfacedwith any chiller controller. It then operates identical to the chiller-mounted keypad/display. Thusthe operator has full access to all networked chillers from a single remote location. Panel-mountedLED’s clearly indicate which controller the RMS panel keypad/display is currently interfaced with.


Monitor softwareWhen properly equipped with MicroTech Monitor software, a direct or remote connected PC can beused for monitoring unit operation, changing setpoints, scheduling, trend logging, downloadingcontroller software, and diagnostics. For MicroTech network systems, the PC gives the operatoraccess to all unit and auxiliary controllers in the network. Specific controller or global data can bedisplayed as desired. All keypad status information and control capability is available at the PC in afull-screen format. Many additional unit control parameters, which are not available at the unitcontroller’s keypad, are also available. Monitor software provides the following features:

• High resolution, unit-specific graphic representations• One-touch function keys• Multiple unit display screen• Automatic screen refresher• Help text• Dial-up communications• Alarm monitoring and management• Scheduling• Trend logging• Downloading capability• Multi-level password protection• Controller Diagnostics

Open ProtocolMicroTech Open Protocol Master panel provides an interface between MicroTech unit controllersand virtually all building automation systems (BAS). A protocol is a set of rules governing dataexchange between microprocessors, thereby permitting communications between unlike controllers.As a result, building designers, owners and operators can obtain the advantages of McQuayequipment, and the control versatility MicroTech has to offer. A low cost site license covering anyand all McQuay product is required.

MicroTech BACdrop GatewayThe McQuay BACdrop Gateway panel allows any BACnet based building automation system(BAS) to communicate with MicroTech controllers. The panel translates between the standardBACnet protocol (ANSI/ASHRAE 135-1995) and the MicroTech protocol. No modifications to theMicroTech hardware or software are necessary. Since BACnet is a standard, public protocol nolicense agreement is necessary.


Selection Procedure

EW Water-Cooled, R-221. Ratings are based and certified in accordance with ARI Standard 550/590-98.2. Ratings in Table 5 through Table 10 may be interpolated for any chiller water temperature

between 40°F and 50°F (4.4°C and 10.0°C) but cannot be extrapolated.3. Chilled water quantities - Ratings are based on a 10 degree F (5.6 degree C) chilled water range

(2.4 gpm/ton) and can be used for a delta-T range of 6 to 16 degrees F (3.3 to 8.8 degrees C) byadjustments from Table 3.

4. Figure 2 through Figure 4 give the evaporator water pressure drop data. Water flow ratesshould be maintained within these limits, which are based on minimum and maximum flow.

5. Ratings are based on 0.0001 fouling factor for the evaporator. For other fouling factors,multiply ratings by evaporator factors from Table 3. For applications using a glycol solution,see Table 1 and Table 2.

6. Ratings are based on condenser flow of 3 gpm/ton (10 degree F, 5.6 degree C delta-T) and0.00025 fouling factor. Corrections for other conditions are in the following ApplicationSection.

5. From Figure 2 for the WHR-070EW, evaporator pressure drop at 165 GPM is 6.2 feet

6. From Figure 3, the condenser pressure drop at 210.6 GPM is 12.5 feet water.

EW Water-Cooled, R-134aUse the same selection procedures as with R-22 except multiply the values in the R-22 PerformanceTables as follows: Capacity x 0.68, Power x 0.65, EER x 1.05.

EA Remote Condenser, R-22

Selection MethodThe performance of the WHR chillers is listed by LWT (leaving chilled water temperature) and byCondensing Temperature . Tons, Power, and THR (Total Heat Rejection) are given. This data canthen be used to select any condenser from its own capacity data. For a McQuay AC/AQ air-cooledcondenser, use product manual PM ACAQ.

1. Ratings may be interpolated for any chiller water temperature between 42°F and 50°F butcannot be extrapolated (contact factory for ratings outside this range).

2. Chilled water quantities - Ratings are based on a 10 degree F chilled water range and areapplicable from a minimum of 6 degrees F to a maximum of 16 degrees F differential betweenentering and leaving chilled water temperatures.

3. Ratings are based on .00025 fouling factor for both condenser and evaporator. For otherfouling factors, multiply ratings by cooler factors from Table 3 and Table 4. For applicationsusing a glycol solution, see Table 1 and Table 2.

Selection ProcedureNormally the required chiller capacity in tons, the entering and leaving chilled water temperatureand flow and the design outdoor air temperature are known. Determine any unknown quantityusing the formula:

Tons = gpm x delta T / 24

Capacity data is in Table 12 and Table 13 for IP units and Table 14 and Table 15 for SI units. Ratingare based on:

• Leaving chilled water temperatures from 42°F to 50°F (6°C to 10°C) with a 10 degree delta-T.Selections can be interpolated between these leaving temperatures but not extrapolated.


Correction factors for delta-Ts other than 10 degrees are in Table 3 and Table 4. Exceeding theDelta-T range of 6 to 16 degrees will cause problems controlling unit unloading.

• Condensing temperatures (CT) from 105°F to 125°F (40°C to 55°C).

• Total Heat Rejection (THR) is given and used to select the condenser, whether it be a dry air-cooled condenser or an evaporative condenser.

Several different size condensers can usually be matched to any given WHR-EA unit depending onthe condensing temperature that typically ranges from 20 to 30 degrees F above the design outdoortemperature. Increasing condensing temperatures will reduce the chiller capacity, increase its powerconsumption and result in a smaller condenser being required.

Normally a WHR-EA is selected to meet or exceed the required cooling capacity at somecondensing temperature and a condenser then selected with sufficient capacity to handle the heatrejection with the selected temperature difference (TD, difference between design outdoor dry bulbtemperature and condensing temperature).

A more accurate solution can be achieved by plotting the capacity of the chiller and the condenseras a function of the TD and observing the curves intersection that is the system balance point. Anexample is shown in the following "Selection Example" section.

Sample SelectionsGiven: Required capacity of 100 tons cooling 240 gpm of water from 54°F to 44°F with 95°F designdry bulb temperature. Evaporator fouling factor of .00025.

a) WHR 110EA at 110°F CT; 102.5 tons, 107.3 kW, 1596.5 THR, 1.05 kW/ton

b) WHR 115EA at 115°F CT; 101.0 tons, 112.8 kW, 1597.3 THR, 1.12 kW/ton

c) WHR 120EA at 125°F CT; 103.4 tons, 135.1 kW, 1701.5 THR, 1.30 kW/ton

Note that the condensing temperature has significant influence on the chiller efficiency.Progressing from a) to c) above will require smaller condensers, offset by larger, moreexpensive chillers and lessening efficiency.

2) A condenser can be selected with the above information. For this example, a McQuay ModelACAQ air-cooled condenser will be selected using selection procedures and data contained inProduct Manual PM ACAQ. A model ACD (double row of fans, standard fan speed) will beused.

a) For the WHR 110EA at a TD of 15 degrees F (110°F - 95°F) no selection appears possiblebased on the simple selection method. However, it is close and the graphical method maygive a solution.

b) For the WHR 115EA at a TD of 20 degrees, a Model 175A will do the service.

c) For the WHR 120 EA at a TD of 30 degrees, a Model 115A will do the service.

Selection c) will prove to be considerably lower in first cost but carries a 16 percent efficiencypenalty.


3) Graphical solution to Case a) is shown below.

d) The THR for the WHR110EA is plotted using twopoints; TD=10 degrees(105°F-95°F) and TD=25degrees (120°F-95°F).

e) The THR for the ACD 210Ais plotted using its capacityat TD+15 degrees andTD=18 degrees.

f) The curves intersect atTD=16.5 degrees or 111.5°Fcondensing temperature.

g) Extrapolating the WHRcapacity at 111.5°F gives101.5 tons which will meetthe job requirements. It willbe the highest cost butmost efficient unit.

EA Remote Condenser, R-134aUse the same selection procedures as with R-22 except multiply the values in the R-22 PerformanceTables as follows: Capacity x 0.68, Power x 0.65, EER x 1.05.

Selection Adjustment Factors

Ethylene and Propylene Glycol FactorsWHR units are designed to operate with a leaving chilled fluid temperature from 21°F (-6.1°C) to60°F (16°C). Leaving chilled fluid temperatures below 40°F (4.6°C) result in suction temperatures ator below the freezing point of water and a glycol solution is required. The use of glycol in theevaporator will reduce the performance of the unit. The reduction in performance depends uponthe glycol concentration. This should be taken into consideration during initial system design.

McQuay encourages a minimum concentration of 25% be provided on all glycol applications.Glycol concentrations below 25% are too diluted for long-term corrosion protection of ferrousmetals and corrosion inhibitors may need to be recalculated. Glycol in the condenser will have anegligible effect on performance because glycol at higher temperatures will perform withcharacteristics similar to water.

Evaporator and Condenser Delta-T FactorsPerformance tables are based on a 10°F (5°C) temperature difference through the evaporator andcondenser. A temperature difference other than 10°F (5°C) will result in unit performance beingdifferent from what is shown. Adjustment factors for applications having temperature dropsbetween 6°F and 16°F (3.3°C to 8.9°C) can be found in Table 3 and Table 4.

Fouling FactorPerformance tables are based on water with a fouling factor of 0.0001 ft2 x hr x °F/BTU (0.0176 m2 x°C/kW) in the evaporator and 0.00025 ft2 x hr x °F/BTU (0.044 m2 x °C/kW) in water-cooledcondensers according to ARI 550/590-98. As fouling is increased, performance decreases. SeeTable 3 and Table 4 for performance with other fouling factors.

To ensure optimum unit operation, proper water treatment must be maintained. Scaling and dirt in asystem will vary significantly depending on local water conditions. Water treatment should bebased on characteristics of the area’s water. Improper or untreated water may lead to scale build up,erosion and corrosion in both the condenser and evaporator. McQuay will not acceptresponsibility for poorly or improperly treated water.

NOTES:1. Compressor RLA values are for wire sizing purposes only and do not reflect normal operating current draw.2. Compressor LRA values for part winding start are for the first winding.3. Unit wire sizing amps are equal to 125% of the largest compressor-motor RLA plus 100% of RLA of all other loads in the circuit

including control transformer. Wire size amps for separate 115V control circuit power is 11 amps.4. Single point power supply requires a single fused disconnect to supply electrical power to the unit.5. Supplemental overloads are used in conjunction with standard inherent overload protection. The supplemental overloads:

• Reduce wire sizing amps• Add additional protection• Lower compressor amperage

6. Part Winding Start is a special option on 460 and 575 volt units.

NOTES:1. Unit wire sizing amps are equal to 125% of the largest compressor-motor RLA plus 100% of RLA of all other loads in the circuit including

control transformer. Wire size amps for separate 115V control circuit power is 11 amps.2. Single point power supply requires a single fused disconnect to supply electrical power to the unit.3. Multiple point power supply requires three independent power circuits with separate fused disconnects. (Two compressor circuits, one

control circuit.)4. Supplemental overloads are used in conjunction with standard inherent overload protection. The supplemental overloads:

Application Data

Location and Space RequirementsThe units are designed for indoor application and must be located in a space where the temperatureis 40°F (4.4°C) or above. Provide clearance of 2 to 3 ft. (609 to 914 mm) on each side and ends forpiping and to help when servicing unit.

Provide clearance at either end of the unit to permit cleaning of condenser tubes or for removal oftubes from condenser or cooler (see dimensional data). If a door or window is provided at one endof the unit, the tubes may be replaced through the opening provided.

FoundationMount the unit on a level concrete foundation. Floors must be strong enough to support the unitweight. If necessary, use structural supports to transfer the weight of the unit to the nearest beams.

Vibration IsolationVibration mounts are recommended for upper floor installations or where compressor noises mightbe objectionable (next to occupied spaces such as offices, meeting rooms, etc.).

Vibration eliminators may be used for water piping connected to the unit to avoid transmission ofwater or pump noise into occupied spaces.

System water volume considerations:All chillers need adequate time to recognize a load change, respond to the change and stabilizewithout short cycling the compressor. The water volume in the system and the size of the pipingloop is a critical consideration. Good engineering practice is to have a minimum water volume ofseven times the flow rate (GPM) for comfort cooling applications. For process applications wherethe load can change quickly, contact the factory for recommendations. A water storage tank(provided by others) may be required to increase the system water volume in some systems.

Typical Chilled Water PipingFlush the system water piping thoroughly before making connections to the unit evaporator. Installa 40 mesh strainer in the return water line before the inlet to the chiller. Design the water piping sothe chilled water circulating pump discharges into the evaporator inlet.

Connect chilled water return water line to evaporator inlet connection. And the supply water line toevaporator outlet connection.

Install a flow switch in the horizontal piping of the supply (evaporator outlet) water line.

Provide drain connections at low points in the system to permit complete drainage of the system.Air vents should be located at the high points in the system to purge air out of the system. A ventconnection on top of the evaporator vessel allows air to be purged. Purge air from the water systembefore unit start-up to ensure adequate flow through the evaporator.

Install pressure gauges in the inlet and outlet water lines to the evaporator. Measure pressure dropthrough the evaporator to calculate proper flow. Vibration eliminators are recommended in both thesupply and return water lines.

Chilled water piping should be insulated to reduce heat loss and prevent condensation. Chillers notrunning in the winter should have their water systems thoroughly drained to protect againstfreezing. If the chiller operates year round, or if the system is not drained for the winter, protect theoutdoor chilled water piping against freezing. Wrap the lines with a heater cable and add properamount of glycol to the system to further protect the system.


Figure 14, Typical chilled water piping

Condenser Water (EW Units)Be certain the condenser water enters the bottom connection of the condenser. The condenserwater will exit the condenser from the top connection. Head pressure control must be provided ifthe entering condenser water can fall below 60°F. Fan cycling and modulating discharge damperson the cooling towers or a three-way bypass valve around the tower is often used. Consult thetower manufacturer for information on specific applications.

If city or well water is used for condensing, a two-way pressure actuated water regulating valveshould be installed in the outlet piping of each condenser. The condenser purge valve provides aconvenient pressure tap for the regulating valve. The valve can modulate in response to headpressure. When the compressor shuts down, this valve closes, preventing water from beingsiphoned out of the condenser.

Low Temperature ApplicationsCompressor unloading is acceptable for applications with 35°F or higher leaving fluid temperatures(LFT). For applications where the LFT is less than 35°F, only full load compressor operation isallowable. Due to reduced refrigerant flow, motor cooling can become a problem. If compressorpart load operation is required below 35°F LFT, contact the factory for additional requirements. It isacceptable to use UNT or MicroTech controls for applications with 35°F LFT or lower provided thatonly one LFT setpoint is needed.

Ice Storage ApplicationsIce storage applications must use Microtech controls. The Microtech has logic to changesetpoints from the low ice making mode to higher normal comfort cooling setpoints. It is importantthat the Microtech controller receive a signal to convert from ice mode to normal operating mode.Microtech includes the logic to keep compressors fully loaded when operating in the ice mode.The double insulation thickness option is recommend to prevent sweating.

Two Pipe SystemsWhen the same two pipes are used for both heating and cooling water, several limitations should beobserved. The maximum allowable temperature that the evaporator should experience in a non-operating mode is 100 degrees Fahrenheit. For unit operation and system changeover from heatingto cooling, the maximum allowable temperature entering the evaporator is 90 degrees Fahrenheit.System controls provided by others should prevent chiller operation until the loop temperaturedrops to 90 degrees. When the loop water temperature ranges between 75 and 90 degrees enteringthe evaporator, the high return water staging thermostat should be used to prevent compressoroverloading.


Series or Parallel OperationConsider system pressure drop when designing the water piping. Parallel piped systems have halfof the total system flow going through the evaporator of each chiller, reducing the individual unitand total system pressure drop.

Series piped evaporators require that the total system water flows through both evaporators. Notonly is the pressure drop through each evaporator increased but the pressure drops must be addedtogether to obtain the total evaporator pressure drop. Series piped evaporators normally requirelarger circulating pumps for the chilled water system.

Electrical ConnectionEvery WHR chiller requires field installation of the main supply power plus flow switch and pumpstarter relay. A control circuit transformer installed at the factory eliminates the need for fieldinstallation of a separate 115V supply to the control circuit. A separate 115V field connection to thecontrol circuit can be substituted. A system time clock and remote on-off switch can also be fieldinstalled.

See Figure 5, Field Wiring Diagram, on page 44 for field electrical hookups. The diagram shownrepresent all WHR units; however, individual terminal numbers may vary between unit sizes. Eachunit is provided with its specific wiring diagram in the control panel. All wiring must be doneaccording to local and national codes.

Main Power Supply Disconnect SwitchEvery WHR unit uses a single factory installed main power supply terminal block as standard. Themain power supply terminal block will accept single or parallel power supply wiring.

A field installed non-fused disconnect switch with an optional thru-the-door handle (required tomeet NEC Code for disconnects) is available as an option on WHR 040 and above with single pointpower supply. The disconnect switch is properly sized for the model and voltage supplied.

A field supplied and installed remote disconnect switch can also be used.

Control CircuitA control power transformer is standard equipment on WHR units. Terminals are provided in theunit control center (terminals 1 and NB, typical field wiring diagram) for field connection to a remotecontrol circuit to a 115V power supply if desired.

Terminals are also provided for field connection of the chilled water flow switch, unit time clock,ambient thermostat and/or remote on/off switch.

Compressor Time LockoutA fixed 5-minute solid-state lockout time delays compressor restart after safety cutout or powerinterruption, or under irregular cooling load demands.

Interlock WiringThe condenser water pump should be interlocked to cycle with the compressor(s). This willprevent the refrigerant pressure from being overly depressed during the off cycle and allows theenergy savings of pump shutdown. Interlock terminals are provided in the unit control panel.


Design Limitations1. Maximum allowable condenser water pressure is 225 psig (1550 kPa).

2. Maximum allowable evaporator water pressure is 175 psig (1206 kPa).

3. Maximum design saturated discharge temperature (SDT) is 140°F (60°C). SDT=Condensingtemperature + discharge line loss.

4. Maximum allowable water temperature to evaporator in a non-operating cycling is 100°F(37.8°C). Maximum entering water temperature for operating cycle is 90°F (32.2°C) (duringsystem changeover from heating to cooling cycle). An optional return water unloadingthermostat is required for return temperatures greater than 75°F (23.4°C).

5. Minimum design leaving water temperature from the evaporator without freeze protection is42°F (6°C).

6. Contact your McQuay representative for operation with tower condenser water entering thechiller below 70°F (21.1°C).

7. Compressor unloading is not allowed with leaving chilled fluid temperatures 35°F or less.

8. The optional Microtech control is required for ice storage applications.

9. The maximum altitude for air-cooled condensers is 6,000 feet.

10. Consult factory for ambient operation below 0°F (-17.8°C).

Remote Condenser Refrigerant Piping

GeneralCareful design of refrigerant piping is necessary for proper system operation. The refrigerantpiping should be designed to accomplish the following:

1. Assure proper refrigerant feed to the evaporator.

2. Provide practical and economical refrigerant line sizes without excess pressure drop.

3. Maintain uniform oil return to the compressor under all load conditions.

4. Refer to the latest version of the ASHRAE Handbook for recommended piping practice.

Limit the length of refrigerant piping by locating the condenser as close to the chiller as possible.Avoid all unnecessary changes in direction or elevation. On dual circuit units, the condensers mustbe selected with separate condenser sections so that the circuits are not combined and precautionstaken to avoid cross-connecting the circuits.

Liquid LineWhere there is a vertical lift from the condenser to the chiller, adequate subcooling must beprovided to prevent liquid flashing before the expansion valve. A shutoff valve should be installedin the liquid line to allow isolation of the remote condenser.

Discharge lineThe discharge line should be trapped at the compressor and looped at the condenser (inverted trap)to prevent liquid refrigerant from draining back onto the compressor heads. Pressure drop shouldbe held at a minimum.


Optional Features

Hot Gas BypassFactory mounted hot gas bypass permits unit operation down to 10% of full load capacity andincludes a hot gas bypass valve, solenoid valve and manual shutoff valve. Hot gas bypass isprovided both refrigerant circuits.

Vibration IsolatorsSpring or rubber-in-shear vibration isolators are available as a kit for field installation to reducevibration transmission through the unit base.

Water Flow SwitchA field installed water flow safety switch in the chilled water piping prevents evaporator freeze-upunder low or no flow conditions. Terminals are provided in the unit control center for field hookupof the water flow safety switch.

Disconnect Switch (WHR 040 through 210)A field installed non-fused disconnect switch with thru-the-door- handle is available as an optionwith single point power supply (requires modifications to the control panel door. The disconnectswitch is properly sized for model and voltage required. The optional thru-the-door handle kit isrequired if the disconnect switch is to meet disconnecting provisions of the NEC when a separateexternal disconnect is not used.


Through-the-Door Handle KitsKits are available for 225, 250, 400, 600, 800 and 1200 amps. To select the proper kit, refer themaximum fuse data in the catalog for the desired chiller and voltage. Select the kit size that is equalto the maximum fuse size. If an exact match is not listed, it is acceptable to use the closest size kitthat exceeds the maximum fuse size.

Circuit BreakersFactory installed circuit breakers are available as an option of unit sizes WHR 040 through 090 withsingle point power supply. Circuit breakers are standard on unit sizes WHR 017 through 030 andWHR 095 through 210 with single point power. This option provides unit installed compressorshort circuit protection.

Alarm BellA field installed 24 volt alarm bell signals safety trip of the freeze protection pressurestat, highpressure cutout, oil failure cutout, or motor overload. The bell is factory mounted on the unitcontrol center. A time clock is also available with a spring carryover. During normal operation, thespring is wound to operate the clock for up to ten hours should the power be lost to the unit.
