Why Evaporative Condensers?
Low Energy CostsThe primary reason for specifying evaporative condenser units is the significantly reduced energyconsumption. This is equally true for chillers, condensing units or packaged rooftop units-anyrefrigeration system that rejects heat to the atmosphere. Evaporative condensers have been amainstay in the food processing and many other industries for years. The reason is low system energycosts.
The Evaporative Condensing EffectEvaporative condensers gain their efficiency advantage from some simple principles:
1. Like any pump, a refrigeration compressor's energy requirement is proportional to the head(pressure difference) it has to work against. Most chillers used for air conditioning, regardless oftheir condensing medium, generate 42°F to 45°F chilled water, and so they have about the samecompressor suction condition.
2. Evaporative condensers, similar to cooling towers, reject heat to the atmosphere by evaporatingwater that is sprayed over the condenser coil. The condensing pressure is limited by the wet bulbtemperature. Air-cooled condensers are limited by the ambient dry bulb temperature which istypically 20 to 30 degrees F. higher than the wet bulb temperature.
3. Evaporative condensers are actually more effective than a cooling tower/water-cooled condensercombination since there is no intermediate heat exchanger loss.
4. Evaporative condensers provide the lowest condensing pressure (and hence the most efficientoperation) of any device that rejects heat into the ambient air.
The Effect on Chiller EfficiencyThe ASHRAE Efficiency Standard 90.1-1999 does not set efficiency standards for evaporatively-cooled chillers. The McQuay EGR evaporative condenser chillers average EERs of 14 at full load,equivalent to 0.85 kW/ton. ASHRAE 90.1 requires a minimum of 9.6 EER for air-cooled chillers.Most manufacturers are at 9.6 to 9.9 EER or about 1.25 kW/ton. These efficiencies are at ASHRAEstandard conditions of 95°F dry bulb and 75°F wet bulb temperatures.
This amounts to energy savings of 0.4 kW/ton in favor of the evaporative condenser. Expressedanother way, a one-third reduction in energy cost compared to air-cooled units. This percent savingholds true for part load operation as well.
Dry Climates?Many people have the mistaken idea that evaporative condensers are only for arid, low wet bulbclimates. The efficiencies noted in the previous paragraph are at normal climate conditions, i.e.,ASHRAE standard temperatures. Evaporative condensers should be considered in all climates, evenwhere humidity can be high.
But it is true that the energy savings are more pronounced in dry climates. Consider Las Vegas,U.S.A. with design conditions of 108°F dry bulb and 66°F wet bulb temperature. Air-cooled chillerswill be operating at about 1.5 kW/ton, while the evaporative condensers are using only 0.7 kW/ton.That's less than one-half the electric consumption and cost!
Evaporative condensers do use water, about 2.4 gph/ton, including evaporation, drift and bleedmakeup. This must be considered since dry climates can have water availability problems. Air-cooled chillers use no water but consume a great deal more energy.
McQuay offers water treatment and water quality sensing options to reduce water consumption.

Benefits of McQuay EGR/ECR Units
Of all evaporative-cooled units that are available in themarket place, what makes the EGR/ECR the greatest value?
The Reciprocating Compressor AdvantageReciprocating compressors are an excellent choice for systems utilizing R-22 refrigerant with decadesof reliable service. General service technicians can easily service and maintain these compressors. Inthe unlikely event that a replacement compressor is needed, they are readily available locally.Although McQuay offers products using all types of compressors including screw, centrifugal andscroll compressors, reciprocating compressors were selected for EGR.ECR because of overallperformance, efficiency, serviceability, reliability and durability.
Efficiency and Lower Operating CostsReciprocating compressors used with the lower condensing pressures of evaporative cooling are veryefficient. It is extremely important that both full load and part load performance be evaluated beforeselecting a unit.
Full load EER values for EGR units range up to 14.4 at ARI standard conditions of 75 degrees wetbulb and 44°F chilled water temperature. Excellent full load performance is critical when electricaldemand charges are a major portion of the utility costs.
In many locations, part load performance is most important and EGR excels again. The IPLV fortwo-compressors models up to 120 nominal tons range up to 19.9 EER. The IPLV for the four-compressor models of 130 to 240 nominal tons range up to 20.0 EER. A major factor in selectingreciprocating compressors was the ability to use two compressors where other manufacturers use asingle screw compressor or four reciprocating compressors in capacity ranges where typically twoscrew compressors are used. Great part load performance is achieved by turning compressors “OFF”instead of the inefficient operation of larger compressors running unloaded.
Because justification for the higher initial cost of evaporative condenser units is required, it was adesign requirement to maximize full load and part load efficiency. Consequently, McQuay selectedlarge components for optimum heat transfer and multiple reciprocating compressors for each package.
Copper Condenser TubesMcQuay designers refuse to use galvanized steel tubes with their traditional corrosion problems andshortened tube life. Instead, McQuay’s EGR/ECR units use copper tubes as the standard and onlyoffering. Additionally, copper tubes offer superior heat transfer that increases the overall unitefficiency. The additional first cost of copper tubes provides extended unit life and additional unitefficiency.
Stainless Steel CabinetsAgain, McQuay designers refuse to use inferior materials such as galvanized steel for unit cabinets.Being essentially a water-cooled machine requiring chemical treatment for the water in the condensersection, it is extremely important to use materials that will resist the corrosive properties of thechemical treatment. Although costly, stainless steel is an extremely durable material and is a superiormaterial for corrosive environments. Stainless steel panels are used throughout the unit and not justin the condenser section. It is wise to accept nothing less.
Product Manual EGR/ECR 7
Structural Steel FrameContinuing the durable construction theme, the EGR/ECR base and load bearing members arestructural steel. Other units in the market place use sheet metal components with less durability.McQuay units are designed for decades of structural integrity.
Controls FlexibilityThrough the “Open Protocol” format of the MicroTech family of McQuay controls, owners havemaximum flexibility to select the control subcontractor of their choice with few restrictions. McQuayhas agreements with 34 different control partners to make interfaces into building automatic systemsas simple as possible.
Application FlexibilityA wide variety of unit sizes, configurations and options are available to meet your exact requirements.Unit configurations include package chillers, chillers with a remote evaporator that can be placedinside the building for additional freeze protection and condensing units that can be used with avariety of low sides.
Service vestibules are available for easier servicing and monitoring. Hydronic packages can beinstalled inside factory enclosures. Hydronic components include chilled water pumps, expansiontanks, air separators and other piping accessories.
A variety of chemical treatment systems for both solid and liquid chemicals or ozone treatmentsystems are factory installed. To purify the water in the evaporative condenser, solids filtrationsystems are available.
Specify your EGR chiller or ECR condensing unit in the configuration that works best for you.

Unit Description
ConstructionThe McQuay EGR/ECR units have been designed from the beginning as integrated, dedicatedevaporative condenser units. They are factory assembled and mounted on a heavy-duty structuralsteel channel base. This base distributes the unit weight for roof loading. Flexible installation ispossible by virtue of the unit’s small footprint and low sound level.
Evaporative Condenser CabinetTo reduce corrosion potential associated with evaporative condensers, the sump and all metalcomponents exposed to water are constructed of heavy gauge type 304 stainless steel as standard. Astainless steel air inlet screen is provided to prevent air-borne debris from entering the air inlet.
CompressorsThe EGR/ECR product line uses Copeland Discus semi-hermetic compressors. These ruggedcompressors are designed for R-22.
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 threemotor windings, providing inherent thermal overload protection for all run and start conditions.
The compressor housing is constructed from closed grained, high nickel content, alloy cast-iron withno bolted joint between the motor and compressor. The housing includes a cast-iron cylinder head andstator cover, with a crankcase oil sight glass. A suction strainer, which is built into the compressor inthe gas stream between the suction service valve and the motor, filters out foreign and abrasiveparticles. An internal relief valve relieves discharge pressure to the suction side for protection at highcompression ratios as required by ANSI/ASHRAE 15 Safety Code.
Main bearings are solid, cast bronze, insert type with oversized bearing areas that result 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 force-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 magnetic particles that enter the crankcase. The oilsupply filters through a large area oil strainer. A crankcase heater minimizes oil dilution by refrigerantat startup.
Evaporative Condenser CoilsCondenser coils are fabricated of heavy-gaugeType L copper tubes arranged in a staggeredrow pattern. Coils are supported by high-density polyethylene tube sheets to protectagainst galvanic corrosion and abrasion due toexpansion and contraction. An integralsubcooling coil provides subcooling at theexpansion valve to help eliminate the possibilityof liquid line flashing. The coils are arrangedfor easy removal through the side of the unit.

Condenser Fan and MotorAirfoil propeller fans are directly driven by three-phase, totally enclosed, 1.15 SF, corrosion-resistantepoxy finish, stainless-steel shaft, double-sealed, life-time lubricated, ball-bearing type, moisture-resistant winding, class-F insulation wash-down duty motors with inherent overload protection.
The fan(s) for each circuit are equipped with variable speed drive for discharge pressure control. Thefan pitch is adjusted at the factory for the air density at the job site and no further adjustments arerequired. This pre-adjustment eliminates the need for altitude capacity reduction.
Recirculating PumpThe recirculating pump is a direct-drive, variable speed, bronze type with mechanical seal. Inletstrainers mounted in the sump are included. The spray header is PVC with water discharge openingssized to prevent clogging. Discharge is made into a type 304 stainless steel discharge plate.
Spray EliminatorType 304 stainless steel spray eliminators are provided to prevent water carryover.
Evaporator (EGR-AS and AM models only)The evaporator is direct expansion, shell-and-tube type with water flowing in the baffled shell-sideand refrigerant flowing through the tubes. Two independent refrigerant circuits within the evaporatorserve the unit's dual refrigerant circuits.
The evaporator has a carbon steel shell and seamless high efficiency copper tubes roller expandedinto a carbon steel tube sheet.
Refrigerant heads are carbon steel with multi-pass baffles to provide 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.
The evaporator is wrapped with an electric resistance heater cable and insulated with 3/4" (19mm)thick vinyl nitrate polymer sheet insulation, protecting against water freeze-up at ambient airtemperatures to -20°F (-29°C). An ambient air thermostat controls the heater cable.
The fitted and glued in place insulation has a K factor of 0.28 at 75°F (24°C).
The refrigerant (tube) side maximum working pressure is 225 psig (1551 kPa). The water sideworking pressure is 175 psig (1207 kPa). Each evaporator is designed, constructed, inspected, andstamped according to the requirements of the ASME Boiler and Pressure Vessel Code. Doublethickness insulation is available as an option.
On Model EGR-AM units, the evaporator is shipped separately for field mounting and piping to theoutdoor unit. The refrigerant specialties are furnished by McQuay and require field installation byothers. The refrigerant piping schematic shown in Figure 1 indicates the piping connection points forfield piping furnished and installed by the contractor. Schematic is for one of two circuits.

MicroTech ControlThis is an exclusive microprocessor controller common throughout McQuay equipment. Theinterface is a 12-key keypad and 4-line, 40-character backlit liquid crystal display. The MicroTechcontinuously performs self-diagnostic checks on all system temperatures, pressures, and equipmentprotection devices. It will automatically shut down a circuit or the entire unit upon fault conditions.The cause, time, and date of the occurrence is recorded and can be displayed. The seven previousincidents are kept in memory for service reference.
If a fault occurs, the controller takes preventive measures in an effort to keep the unit operating;staging down capacity, activating a pre-alarm signal, and automatically switching to the alarm menuon the display.
Pre-alarms are self-clearing when the fault condition is no longer present.
Critical shutdown alarms such as high condenser pressure (with mechanical backup), freezeprotection, water circulating pump failure, oil pressure (with mechanical backup), and low evaporatorpressure are manual reset and must be cleared at the keypad to resume operation.
Choose the Open Protocol option to interface with virtually any building management system andperform remote monitoring and control by hard wiring or modem. A nominal site license fee isrequired for a building automation system (BAS) interface.
A single chiller can connect directly to the BAS. Two or more units will require an Open ProtocolPanel (OPM) for connection.
Thirty feet of sensor cable is included, rolled up in the control panel on remote evaporator models.

Optional Water Treatment (All Units)OverviewThere are numerous strategies to mitigate the effect of the evaporating water in evaporative condenserunits. McQuay offers all the normally accepted methods as optional equipment. The purpose of thesesystems is to:
• Control organic contamination• Reduce condenser fouling and corrosion• Reduce cleaning frequency and water usageThe following types of water treatment systems are available:
1) Water Treatment Systems that control the quality of the water:
a) Dry chemical systems that meter two dry chemicals into the recirculating water
b) Wet chemical systems that meter two wet chemicals into the recirculating water
c) Ozone treatment systems that generate ozone from air by corona discharge. Ozone is astrong oxidant that kills bacteria.
2) Solids Removal System that removes accumulated particulate matter by a non-mechanicalcentrifugal solids separator. The removed solids are then handled in either of two ways:
a) Bag type collector that collects solids in a bag for periodic removal
b) Automatic purge valve that purges all solids when needed
3) Bleed-off is the systematic draining of a small quantity of the recirculated water (and subsequentautomatic makeup) to reduce the dissolved solids. Bleed-off is sometimes the only method usedto control water quality. It can be done in two ways:
a) Manual - A manually adjusted valve located in the pump discharge drains a fixed amount ofwater from the system. This method can easily remove too much or too little water.
b) Automatic - An automatic valve controlled by a conductivity controller sensing the wateralkalinity drains the proper amount of water to maintain water quality. Recommended forunits without any of the Water Treatment Systems listed above. Automatic bleed-off isincluded in all of the three Water Treatment Systems listed above.
Optional Dry or Wet Chemical Water Treatment SystemsChemical Treatment System – Factory-installed, highquality, chemical injection equipment, matched to McQuayEGR/ECR evaporative condenser units is available. Thesystem controls the microbiology, scale, and corrosion in therecirculated water. Chemical supply and service contracts areprovided by others.
Features and Benefits:Factory-mounting reduces field labor, risk and spacerequirements.
Consultation, analysis, chemicals, and service are providedby others.
Dry Chemical Injection System
Product Manual EGR/ECR
Product Manual EGR/ECR 13
Chemical Treatment
This is a traditional, proven treatment that is available in either dry or liquid form, consisting of two(either dry or liquid) chemical feeding systems, chemical/side stream mixing system, timer control toshock-feed the biocide, and corrosion inhibitor and bleed-off controlled by a conductivity meter.
Dry: Dry chemical feed system mixes water with two solid chemicals. Solid chemicals are suppliedby others in easy-to-handle containers that are designed to minimize chemical exposure to operators.
Liquid: Traditional liquid feed, factory-installed chemical unit is available depending on preference.Unique design reduces chemical exposure to operators.
Optional Ozone Water TreatmentThe Chemical Free Water TreatmentSystem - Environmentally friendly ozonewater treatment, custom-designed for theMcQuay EGR/ECR evaporative condenserunits is available. The ozone system isdesigned to control microbiology, scale,and corrosion in the condenser water. Itincludes a conductivity controller and asolenoid bleed-off valve to maintainproper water chemistry. ozone generatingsystem, and ozone/side stream mixingsystem. All equipment is factory mounted.The ozone water treatment system iscapable of producing adequate ozonequantities from an oxygen gas feed at a15% ozone concentration. The ozone system treats full condenser water circulating flow at the sitedesign wet-bulb temperature. The ozone generator dialectic produces ozone via a corona dischargeand concentrated oxygen feed. A pressure swing adsorption type oxygen concentrator that is suppliedwith compressed air produces concentrated oxygen. Automatic control of ozone production throughORP monitoring is included. The ozone treatment system is factory mounted and wired.
Features and Benefits:• Factory-mounted, assembled, and tested --- reduces field labor, risk and space requirements.
• No chemicals needed --- no storage costs, no specially trained personnel, and no specialequipment.
• Single-source supply --- only one point of contact.
14 Product Manual EGR/ECR
Optional Side Stream Solids Filtration System:• Strainer to rid water of large solids before they enter
the pump
• Pump (sized for 10-20% of total flow rate)
• Centrifugal Solids Separator (Filters 98% of all solidsfrom 5 to 70 microns in size with no moving parts)
• Solids Collection Vessel---two systems available. Firstis a bag-type collection system that collects solids at apredetermined size and then transmits a signal when itis ready to be manually changed. The second systemis an automatic purge valve that purges all solidsmechanically when needed. No labor is necessary forthe second option.
• Controls---for Pump and Chemical InjectionEquipment
How the Solid Separator System Works:
• 20% of total flow rate is taken from the sump side of thewater collection basin.
• This stream is fed through a strainer that removes large particles before entering the pump.
• The pump then forces the water through the centrifugal separator where most solids greater than5 microns in size are removed.
• The solids removed by the separator are forced into the solids collection vessel where they willcollect in a bag to be removed or where they will be purged automatically.
• “Basin sweep” nozzles are strategically positioned in the basin so that the newly filtered waterforces solids toward the sump side of the basin.
Optional Automatic Bleed-OffBleed-off can be accomplished automatically by use of an optional factory-installed conductivitycontroller that operates a bleed valve in the recirculating pump discharge. The controller measuresthe amount of undissolved solids in the water and operates the bleed valve to control the solids withina predetermined value. This is a stand-alone system, but it's also included with any of the watertreatment systems.
This automatic bleed control is far more efficient than attempting to regulate a manual bleed-offquantity. Bleeding off too much water incurs excessive water costs and too little will result in solidsdisposition leading to inefficient coil operation and corrosion.
Option for Low Ambient OperationStandard Ambient Air Operation to 40°°°°F; the unit will operate down to 40°F using the standardvariable speed fans and recirculating pump to control discharge pressure. Other than the built-inevaporator heater on EGR models there is no protection provided against freeze-up and the unit mustbe winterized.
Optional Low Ambient Air Operation Below 40°°°°F; at 40°F the condenser water-circulating pumpis turned off at which point the condenser operates as an air-cooled unit. When the condenser pumpswitches off, the head pressure will increase and the fan speed will automatically increase to maintainadequate head pressure.
Electric heat cables on the recirculating water piping and pump, plus a sump immersion heater will beenergized.
Centrifugal Solids Separator
Product Manual EGR/ECR 15
When the sump temperature drops to 34°F, the sump and circulating water piping will dumpcontained water to a drain or optional field-installed indoor sump (tank provided by others). Whenthe dump signal is given, the water piping heaters, sump immersion heaters and the recirclating pumpwill be de-energized and the unit's field installed makeup water solenoid valve will close. A contact isavailable to operate this remote shut-off valve.
On EGR-AS units the evaporator vessel has a built-in heater that will energize at approximately 40°Fto protect the evaporator water from freezing. NOTE: Outdoor chilled water piping must also beprotected from freezing by field-installed heaters.
In the event of a power failure, the sump, circulating pipe and pump water will dump to a drain orindoor sump (tank).
If the unit will not be operational during periods of freezing temperatures, it must be winterized bycompletely draining all the recirculating water system.
Optional Service Vestibule (All Units)A 4-foot wide service vestibule located in front of the control panels is available as a factory-installedoption. The vestibule provides a weather-protected, illuminated space from which to check andservice the controls.
Optional Chilled Water Pump Room (EGR-AS only)McQuay offers factory-installed chilled water pumps for model EGR evaporative condensing chillers.Pumps, controls, expansion tank and hydronic accessories are mounted on an extension of the chillerbase that is enclosed in a factory-built, climate-controlled and lighted equipment space.Interconnecting piping between the chilled water pump in the pump room, and the evaporator underthe unit proper is shipped with the unit for field installation.
Components are selected specifically for job conditions.
Nominal additional lengths are 8’, 12’ and 16’.

Determine the evaporator pressure drop. Using Figure 4 on page 38, enter at 151.2 (flow rate forwater) and follow up to the EGR 065AS line intersect. Read horizontally to obtain an evaporatorpressure drop of 13.0 feet. Correct the pressure drop for 40% glycol solution = 1.263 X 13.0 feet =16.4 feet of water.
Remote Evaporator, Model AMSince the EGR-AM units always include a specific remote shell-and-tube evaporator, the capacity ofEGR units with remote evaporators is based on leaving chilled water temperature and ambient air wetbulb temperature from the Rating Tables corrected for line loss as follows.
Ratings are found in Table 4 through Table 11. The tables are based on a 10°F temperature dropthrough the evaporator and a fouling factor of 0.0001 ft2 x hr °F/Btu. Adjustment factors forapplications having other than a 10°F drop or 0.0001 fouling can be found in Table 3. There is nocorrection necessary for altitude since the adjustable pitch fans are factory adjusted to provide thecorrect airflow for the job location.
The minimum leaving chilled water temperature setpoint without glycol is 40°F. For glycolselections, see Table 1 for ethylene glycol or Table 2 for propylene glycol adjustment factors. Forapplications outside the catalog ratings, contact your local McQuay sales representative.
The length and configuration of the interconnecting refrigerant piping will affect the system capacity.The capacity derate for refrigerant piping loss is between two and four percent dependent on themagnitude of the suction line pressure drop. The power input and evaporator pressure drop willremain the same as with AS packaged units.
Refer to the Refrigeration Volume of the ASHRAE Handbook for refrigerant piping design and sizingguidelines. Also refer to the Refrigerant Piping discussion beginning on page 67 of this catalog.

Performance Adjustment FactorsEthylene and Propylene Glycol FactorsEGR units can operate with a leaving chilled fluid temperature range of 20°F (-6.7°C) to 60°F(15.6°C). A glycol solution is required when leaving chilled fluid temperature is below 40°F (5.5°C).The use of glycol will reduce the performance of the unit depending on concentration.
Altitude Correction FactorsHigher altitudes typically require unit capacity derating; however EGR units are equipped withadjustable pitch condenser fans, which are factory-set to increase airflow at high altitude. Thereforethere is no capacity/power correction necessary.
Evaporator Temperature Drop FactorsPerformance tables are based on a 10°F (5.5°C) temperature range through the evaporator.Adjustment factors for applications with temperature ranges from 6°F to 16°F (3.3°C to 8.9°C) are inTable 3. Temperature ranges outside this 6 to 16 degrees F (3.3 to 8.9 degrees C) range can affect thecontrol system's capability to maintain acceptable control and are not recommended.
The maximum water temperature that can be circulated through the evaporator in a non-operatingmode is 100°F (37.8°C). Maximum entering temperature during operation is 90°F (32.2°C).

Fouling factorThe performance data in Table 4 through Table 7 is based on water with a fouling factor of
)/0176.0(/0001.022
kWCmorBTUFxhrxft °×° per ARI 550/590-98. As foulingincreases, performance decreases. See Table 3. for performance at other than 0.0001 (0.0176) foulingfactor.
Foreign matter in the chilled water system will adversely affect the heat transfer capability of theevaporator and could increase the pressure drop and reduce the water flow. To provide optimum unitoperation, maintain proper water treatment.

Notes:1. ARI capacity is at 44°F leaving chilled water 2.4 gpm/ton, 0.0001 f.f. and 75°F wet bulb temperature.2. ARI 550/590 standard does not clearly define the part load performance points. Part load EER is
determined by operating both the pump and full-speed fan until the minimum recommended condensingpressure is reached. At that point, the water pump is stopped and fan speed only is used to maintain theminimum condensing pressure.
3. The wet bulb temperature has linear reduction between 0 load at 50°WB and 75°WB at full load asdescribed in ARI 550/590.

Selection Procedure, ECR Condensing Units
The ECR units are field connected to a direct expansion low side and their selection is based on asaturated suction temperature balanced with the low side equipment and ambient air wet bulbtemperature. The length and configuration of the interconnecting refrigerant piping will determinethe refrigerant pressure drop and hence affect the system capacity.
The rating tables are based on saturated suction temperature at the compressor suction connection andthe design ambient wet bulb temperature.
The selection procedure can start with either the evaporator or condensing unit. If the evaporator isselected first with a given evaporating temperature, the suction line pressure drop (in equivalentdegrees) is subtracted from the evaporating temperature to give the saturated suction temperature. Ifstarting with the condensing unit, the pressure drop is added to the suction temperature to determinethe evaporating temperature on which the evaporator selection is based. If the suction line loss isunknown, a two-degree pressure drop (equal to 3 psi) can be assumed.
Refer to the Refrigeration Volume of the ASHRAE Handbook for refrigerant piping design and sizingguidelines.
Performance Adjustment FactorsAltitude Correction FactorsHigher altitudes typically require unit capacity derating; however ECR units are equipped withadjustable pitch condenser fans, which are factory-adjusted to maintain airflow at altitudes above sealevel. Therefore there is no capacity/power correction necessary.
Notes for Performance Data on Following Pages1) "F&P kW" is the condenser fan and unit circulating pump power input.
2) "PWR kWi" is the compressor power input.
3) "EER" is the unit capacity in Btu/Hr divided by the sum of the compressor power and the F&Ppower expressed in Watts.
4) The unit fans are adjusted for the job site altitude and no adjustment of performance is required.

Note: Per ARI Standard 370
Sound levels are as important as unit cost and efficiency, and must be addressed before to the start ofany development program. Efforts by McQuay design engineers to design chillers that are sensitiveto the sound requirements of the market have paid off.
Background InformationSound is a vibration in an elastic medium and is essentially a pressure and particle displacementphenomena. A vibrating body produces compression waves and as the waves are emitted from thevibrating body, molecules are ultimately compressed. These values are transmitted through gas,liquid, solid - anything which is elastic or viscous.
The sound data provided in this section is presented with both sound pressure and sound powerlevels. Sound power is the total sound energy radiated by a source per unit of time integrated over thesurface through which the sound is radiated. Sound power is a calculated quantity and cannot bemeasured directly like sound pressure. Sound power is not dependent on the surroundingenvironment or distance from the source, as is sound pressure.
40 Product Manual EGR/ECR
Sound pressure varies with the distance from the source and is dependent on its surroundings. Forexample, a brick wall located 10 feet from a unit will affect the sound pressure measurementsdifferently than a brick wall at 20 feet. Sound pressure is measured in decibels (dB), which is adimensionless ratio (on a logarithmic scale) between measured sound pressure and a reference soundpressure level.
Sound Pressure Levels - Full LoadAll sound pressure tables give the overall "A" weighted sound pressure levels which are consideredtypical of what may be measured in a free field with a hand held sound meter, in the absence of anynearby reflective surfaces. The sound pressure levels are measured at 30 feet (10 meters) from theside of the unit at 100% unit load and ARI conditions. 95°F (35°C) ambient air temperature and54/44°F (12/7°C) evaporator water temperatures for air-cooled units.
Sound Power LevelsAcoustical consultants may require sound power octave band data to perform a detailed acousticalanalysis. The tables that follow present sound power levels per ARI Standard 370, “Sound Rating ofLarge Outdoor Refrigerating and Air Conditioning Equipment”. These standards were developed toestablish uniform methods of determining the sound power radiated by large outdoor and indoorequipment. The aforementioned methods are based on providing sound power levels by octave bandand the overall ‘A’ weighted value. Measurements are taken over a prescribed area around the unitand the data is mathematically calculated to give the sound power, dB.
Sound Reduction due to Distance from the UnitThe distance between a source of sound and the location of the sound measurement plays animportant role in minimizing sound problems. The equation below can be used to calculate the soundpressure level at any distance if the sound power is known.
Sound pressure can be calculated at any distance from the unit if the sound power is known.
Lp=Lw-(20 log r) + (10 log Q) - .5
Lp = sound pressure Lw = sound power
r = distance from unit in feet Q = directionality factor
The directionality factor is a dimensionless number that compensates for the type of sound radiationfrom the source. Figure 5 shows the typical Q values of different reflecting surfaces.
For a unit sitting on a flat roof with no other reflective surfaces or attenuation due to grass, snow, etc.,between source and receiver: Q=2.
With Q=2, the equation simplifies to:
Lp = Lw - (20)(log r) + 2.5
Figure 5, "Q" Values
Sound Pressure Levels - Low Ambient OperationUnit operation at a lower ambient temperature than 95°F will also result in lower sound pressurelevels. The sound pressure level will decrease 1 dBA for ambient temperatures between 85°F to 94°F(29.4°C to 34.4°C), 2 dBA for ambient temperatures between 75°F to 84°F (23.9°C to 28.9°C), and 3dBA for ambient temperatures between 65°F to 74°F (18.3°C to 23.3°C).
Uniform Spherical RadiationQ=1 no reflecting surface
Uniform Hemispherical RadiationQ=2 single reflecting surface
Uniform Radiation over ¼ of sphereQ=4 two reflecting surfaces

All Electrical Data notes are on page 46
46 Product Manual EGR/ECR
Notes for “Single-Point or Multi-Point” Power Electrical Data:1. Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA plus
100% of RLA of all other loads in the circuit including the control transformer.2. The control transformer is furnished. A separate 115v power supply can be used if desired.3. If a separate 115V power supply is used for the control circuit, then the wire sizing amps is 10
amps for all unit sizes.4. Recommended power lead wire sizes for three conductors per conduit are based on 100%
conductor ampacity in accordance with NEC. Nominal voltage drop has not been included. It isrecommended that power leads be kept short. All terminal block connections must be made withcopper (type THW) wire.
5. “Recommended Fuse Sizes or HACR breaker size” is selected at approximately 150% to 175%of the largest compressor RLA, plus 100% of all other loads in the circuit.
6. “Maximum Fuse or HACR breaker size” is selected based on 225% of the largest compressorRLA, plus 100% of all other loads in the circuit.
7. The recommended power lead wire sizes are based on an ambient temperature of 86°F (30°C).Ampacity correction factors must be applied for other ambient temperatures. Refer to theNational Electrical Code Handbook.
8. Must be electrically grounded according to national and local electrical codes.9. Minimum Circuit Ampacity (MCA) values shown are for each of two circuits, which are equal.
Voltage Limitations:Within ± 10 percent of unit nameplate rating. Phase imbalance less than 3%.
Notes for “Pump, Compressor and Condenser Fan Amp Draw”:1. Compressor RLA values are for wiring sizing purposes only and can be higher than nominal
operating current draw at rated capacity.2. Compressor LRA for reduced inrush start are for the first winding of part-winding start only.
Notes for “Field Wiring Data”:1. The standard EGR 060 to 120 units and the EGR 130 to 240 units with optional single-point
power require a single disconnect to supply electrical power to the unit. Power supply musteither be fused or use an HACR type circuit breaker.
2. Models EGR 130 to 240 have two power terminal blocks as standard, one for each system in theunit. These units require two disconnects. Each power terminal block supplies both compressor,pump and fan motor power for each system. The control transformer is furnished and connectedto system #1 and #2 through a selector switch.
3. All field wiring to unit power block or optional non-fused disconnect switch must be copper.4. All field wire size values given in table apply to 75°C rated wire per NEC.

Application Data
Unit PlacementEGR/ECR units are for outdoor applications andcan be mounted either on a roof or at ground level.For roof-mounted applications, install the unit on asteel channel or I-beam frame to support the unitabove the roof. For ground level applications,install the unit on a substantial base that will notsettle. A one-piece concrete slab with footingsextended below the frost line is recommended. Besure the foundation is level within 1/4" (7mm) overits length and width. The foundation must bestrong enough to support the operating weightslisted in the Physical Data Tables.
ClearancesDo not block the flow of air to and from thecondenser coil. Restricting airflow or allowing airrecirculation will result in a decrease in unitperformance and efficiency because dischargepressures are increased. There must be noobstruction above the unit that would deflectdischarge air downward where it could berecirculated back to the inlet of the condenser coil.
Install the unit with enough side clearance for airentrance to the coil and for servicing. Provideservice access to the evaporator, compressors,electrical control panel and piping components.
Do not allow debris to accumulate near the unitwhere it could be drawn into the condenser. Keepcondenser coils and fan discharge free of snow orother obstructions to permit adequate airflow forproper unit operation.
Sound IsolationThe low sound levels for the EGR/ECR units aresufficient for most applications. However, therewill be applications where sound levels are anissue. Avoid locations beneath windows orbetween structures where normal-operating soundscan be objectionable. Reduce structurallytransmitted sound by isolating water lines,electrical conduit and the unit itself. Use wallsleeves and rubber isolated piping hangers toreduce transmission of water or pump noise intooccupied spaces. Use flexible electrical conduit toisolate sound through electrical conduit. Springisolators under the unit are effective in reducingthe low amplitude sound generated byreciprocating compressors and for unit isolation insound-sensitive areas.
The recommended minimum side clearance between two units is 10 feet (3048mm). Distance less than 10 feet (3048mm) can result in air recirculation.
The unit must not be installed in a pit or enclosure that is deeperor taller than the height of the unit unless extra space is provided(consult factory). The minimum clearance on each side of the unit is8 feet (2438mm) when installed in a pit.
The minimum clearance to a side wall or building taller than theunit height is 6 feet (1828mm) provided no solid wall above 6 feet(1830mm) tall is closer than 8 feet (2438mm) to the oppositeside of the unit (consult factory for special situations).

Typical Chilled Water PipingFlush the system water piping thoroughly before making connections to the unit evaporator. Debris inthe system can negatively affect performance. Install a strainer of 40 mesh in the return water linebefore the inlet to the chiller. Design the water piping so the chilled water circulating pump dischargesinto the evaporator inlet.
Connect the return water line (pump discharge) to the evaporator inlet connection. Connect thesupply water line to the evaporator outlet connection.
Install and calibrate 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.Locate air vents at the high points in the system to purge air out of the system. A vent connection ontop of the evaporator vessel allows air to be purged out of the evaporator. Purge air from the watersystem before unit start-up to provide adequate flow through the evaporator.
Install pressure gauges in the inlet and outlet water lines to the evaporator. Measure pressure dropthrough the evaporator and compare to flow as shown in Figure 4. Vibration eliminators arerecommended in both the supply and return water lines.
Insulate chilled water piping to reduce heat loss and prevent condensation. Chillers not running in thewinter should have their water systems thoroughly drained to protect against freezing. If the chilleroperates year round, or if the system is not drained for the winter, protect the chilled water pipingexposed to outdoor temperature against freezing. Wrap the lines with a heater cable and add properamount of glycol to the system to further protect the system.
Chilled Water PipingThe thermostat sensor is factory-mounted in the leaving water thermowell on model AS units. Thesensor cable for model AM remote-mounted evaporators must be field mounted in the leaving waterthermowell and the sensor cable field-spliced to the control panel.
Figure 12, Typical Chilled Water Piping
Temperature and Water Flow LimitationsEGR units are designed to operate in ambient air temperatures from 40°F (4.4°C) to 122°F (50°C)with a maximum wet bulb temperature of 82°F (27.8°C). An optional low ambient control allowsoperation down to 0°F (-18°C). The minimum ambient temperature is based on still conditions wherethe wind is not greater than five mph. When possible, position the unit on the downwind side of thebuilding or where the unit will be least affected by wind. For low ambient operation or standbycondition below 40°F, the low ambient temperature option (a sump heater and freeze protection heattapes on the pump and water piping) is required.
66 Product Manual EGR/ECR
Evaporator flow rates below the minimum values can result in laminar flow causing freeze-upproblems, scaling and poor control. Flow rates above the maximum values will result in unacceptablepressure drops and can cause excessive nozzle and tube erosion, potentially leading to failure.
Low Fluid Temperature ApplicationsCompressor unloading is acceptable for applications with 35°F or higher leaving fluid temperatures(LFT). For applications where the leaving fluid temperature (LFT) is less than 35°F, only full-loadcompressor operation is allowed. Motor cooling can become a problem due to reduced refrigerantflow. If compressor part-load operation is required below 35°F LFT, contact the local McQuay salesoffice for additional requirements.
Ice Storage ApplicationsMicroTech controls are suitable for ice storage applications where leaving fluid temperatures arebelow 32°F. The MicroTech has logic to change setpoints from the low ice-making mode to highernormal comfort cooling setpoints. It is important that the MicroTech controller receive a signal toconvert from ice mode to normal operating mode. MicroTech includes the logic to keep compressorsfully loaded when operating in the ice mode. The double insulation thickness option isrecommended to prevent sweating.
Two Pipe SystemsWhen the same supply and return lines are used for both heating and cooling water, severallimitations should be observed. The maximum allowable temperature to the evaporator should notexceed 100°F in a non-operating mode. The maximum allowable temperature for system changeoverfrom heating to cooling is 90°F entering the evaporator. System controls provided by others shouldprevent chiller operation until the loop temperature drops to 90 degrees and prevent water above100°F from entering the evaporator under any circumstances.
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 piping loopis a critical consideration. Good engineering practice is to have a minimum water volume of fourtimes the flow rate (GPM) for comfort cooling applications. For process applications where the loadcan change quickly, contact the local McQuay sales office for recommendations. A water storagetank (provided by others) can be required to increase the system water volume in some systems.
Evaporator Freeze ProtectionNon-operational: To protect against evaporator freeze-up in low ambient temperatures, insulationand an electric heater cable are furnished with the unit. This protects the evaporator down to -20°F (-29°C) ambient. Although the evaporator is equipped with freeze protection, it does not protect waterpiping external to the unit or the evaporator if there is a power failure or heater cable burnout.Consider the following recommendations for additional protection.
1. If the unit will not be operated during the winter, drain evaporator and chilled water piping andflush with glycol. Drain and vent connections are provided on the evaporator to ease draining.
2. Add a glycol solution to the chilled water system to provide freeze protection. The freeze pointshould be approximately fifteen degrees below minimum design ambient temperature.
3. Continuous circulation of water through the evaporator and piping.4. Insulation and heat tracing the chilled water piping.The evaporator heater cable is wired to the 115-volt circuit in the control box. This power should besupplied from a separate source, but it can be supplied from the control circuit. Operation of theheater cable is automatic through the ambient sensing thermostat that energizes the evaporator heatercable for protection against freeze-up. Unless the evaporator is drained in the winter, the disconnectto the evaporator heater must not be open.
Operational: If the unit is expected to operate in freezing temperatures, it should be equipped withthe Low Ambient Temperature option explained in detail on page 14.
Product Manual EGR/ECR 67
Extended ShutdownThis unit is equipped with a recycling pumpdown control system. This permits the compressors torun and re-pumpdown following a 2 hour “off” cycle if the refrigerant evaporator pressure is highenough to close the low pressure cutout (57 to 60 psig). If the unit is expected to be off for anextended period of time, completely de-energize the unit except for piping and chiller vessel heat tapeand drain all water from the condenser recirculating system.
Refrigerant PipingIntroduction (remote evaporator option)Proper refrigerant piping between the unit and a remote evaporator can represent the differencebetween a reliable, trouble free system and months or years of inefficient, problematic performance.The following section is based on ASHRAE information.
System concerns related to piping are:
1. Refrigerant pressure drop
2. Solid liquid feed to the expansion valve(s)
3. Continuous oil return
Of the three listed, the most important and least understood is number 3, “Continuous oil return”.The failure of oil to return at or close to the rate of displacement from the compressor can result in oiltrapping and ultimate compressor failure.
On the other hand, the instantaneous return of a large volume of compressor oil, as a slug, can beequally damaging to a compressor.
Also, more oil is displaced at start-up of a compressor than occurs during a normal running period.Thus, if a compressor experiences excessive starts because of recycling pumpdown control, the largerquantity of oil pumped out is trapped in the condenser with the refrigerant charge, and can not returnregardless of the adequacy of the piping system.
A similar problem to a lesser extent occurs when the equipment is oversized for the available load.
Extreme care should be exercised to provide that both piping and controls are suitable for theapplication such that displaced oil is returned to the compressor moderately. Note, too, that oilloss to the system can be due to a hang-up in the evaporator, as well as in the piping.
SUCTION LINESMcQuay recommends the use of ASHRAE for guidelines in sizing and routing piping. See thecurrent ASHRAE Handbook Refrigeration Edition for tables and guidelines.
Suction line gas velocities can range between 900 and 4000 feet per minute. Consideration should begiven to the possibility of objectionable noise in or adjacent to occupied space. Where this is aconcern, gas velocities on the low side are recommended.
Routing must also take into account the requirement established in the latest ANSI/ASHRAE 15.
Caution: Excessive pressure drop is undesirable because:
• It reduces available compressor capacity.• It increases power consumed from the net tons realized.• It can affect the performance of both the evaporator and the expansion valve previously
selected for the application.
Note: The line loss calculated, expressed in temperature, or PSID pressure drop will be used toestablish the temperature required at the evaporator to produce the required cooling, as well as thesuction pressure that the compressor must operate to deliver the required capacity.
68 Product Manual EGR/ECR
Having selected the suction line size, based upon total equivalent length and maximum tons, verifythat the line size selected will maintain entrainment of the lubricating oil up any vertical risers at theminimum tons for the circuit.
Note: If the line size selected will not maintain satisfactory oil return in a suction riser, the followingoptions are available:
The vertical length can be sized smaller to accommodate the lower circuit tons at reduced load.
Minimum compressor capacity can be increased by eliminating the lowest step of compressorcapacity.
Hot gas bypass can be introduced at the distributor to the evaporator, increasing the volume of gasavailable in the suction line to entrain the oil.
An oil separator can be installed in the discharge line.
With reciprocating compressor units only, and only as a last resort, double suction risers can beutilized. Since a double suction riser works by providing an oil trap to assure the return of some oil,with refrigerant, up the smaller diameter line,
a) the trap must be as small as possibleb) there must not be multiple traps, and whenever double risers are used in a suction line, a
suction accumulator with a controlled oil return should be installed in the line ahead of thecompressor.
In horizontal refrigerant gas lines, oil return to compressors is provided by sizing lines at a velocityabove the minimum recommended and pitching the lines in the direction of refrigerant flow.
SIZING A DOUBLE RISERAt maximum circuit tons, the line size should be selected from the table based upon the recommendedmaximum line loss.
With the minimum tons known, a smaller line size should be selected from ASHRAE Chapter 2,tables capable of entraining oil at the reduced tons. The smaller sized line should be the one installedto be always active.
The net internal area of this smaller sized line should be deducted from the area of the size selected.The remainder represents the area of the other riser. Select a line size with an area equal, or close, tothe calculated net area. The combination of these two risers will provide the required performance atfull circuit tons. The line selected for the minimum load should always be active; and both linesshould enter the overhead horizontal line in a manner to prevent spillage of oil back down the otherriser.
LONG VERTICAL RISER INSTALLATIONWhere job conditions require refrigerant gas lifts of more than 25 feet, McQuay recommends theinstallation of a short trap halfway up the riser or at not more than 20 feet intervals. These traps arerequired to capture and hold small quantities of oil during off cycles.
Liquid LinesLiquid lines are generally sized for 1 to 2 degrees F line losses or their equivalent in pressure drop.Actual selection can vary based upon the pressure drop from solenoid valves, refrigerant driers,valves, piping lifts or risers, and the amount of condenser sub-cooling expected.
The principal concern in sizing and routing liquid lines is assurance (1) that liquid is present in theline at start-up of the compressor, and (2) that liquid, not vapor, is available at the inlet to theexpansion valve during system operation.
Liquid can not be available in a liquid line at start-up if:
1. The solenoid valve is located adjacent to the condenser or condensing unit; remote from theexpansion valve.
Product Manual EGR/ECR 69
2. An excessive length of liquid line is located in a heated ambient and the application permitsmigration of the refrigerant to a cold air-cooled condenser.
3. Liquid refrigerant is permitted to gravitate from the liquid line to the condenser because of therelative location of components.
4. Liquid line solenoid valves should be located adjacent to the expansion valve with possibly onlya sight glass interposing the two.
In the event that (2) or (3) above exist, the application should include a check valve at the condenserend of the liquid line. The check valve should be a low-pressure drop valve. The check valve shouldinclude a pressure relief device, relieving from the line side to the condenser side of the circuit. Therelief can be sized for a pressure differential from 80 to 180 psi (but not more than 180 psi) andshould be auto-resetting as the pressure is relieved.
NOTE
The liquid line should not include a check valve unless the line also includes an automatic resettingpressure relief device. If the relief device being used is relieving from the line to the condenser side of
the check valve, the maximum desirable pressure differential with R-22 refrigerant is 180 psi.
If liquid lines are short, they can be of smaller diameter than the size indicated in the ASHRAERefrigerant Handbook, Chapter 2. As indicated above, the designer must size the liquid line toprovide that pure liquid will reach the inlet of the expansion valve. If the condenser is sized toproduce 10ºF of subcooling, and each degree represents 3.05 psi with R-22, the liquid line and itsrefrigerant specialties can have pressure losses totaling 10 x 3.05 psi and still satisfy the objective ofdelivering pure liquid to the expansion valve.
In calculating the pressure losses, or gains, note that each foot of rise in a liquid line results in anapproximate 0.5 psi loss. Thus a 10-foot rise represents 5 poundxs per square inch loss in refrigerantpressure, or the equivalent of 1.6ºF subcooling with R-22. Total line losses will include values forline friction, equivalents for valves and elbows, and pressure losses from manufacturers’ catalogs fordriers, solenoids, sight glasses, etc.
In estimating condenser subcooling, note that saturated condensing pressure should be read, orestimated, at the same point in the system where the liquid refrigerant temperature is obtained. Thatcondensing pressure is not the discharge pressure read at the compressor outlet. Because it is less, thenet value of subcooling will be lower than might otherwise be assumed.
Where rises in liquid lines result in a 0.5 PSI loss per foot of lift, a drop in the liquid line results in arise in the refrigerant pressure. A substantial drop in the liquid line can provide the existence of pureliquid at the valve. If it is a substantial increase because of a large drop, the expansion valve selectionmust be re-checked to confirm that the valve to be used is not radically oversized.
