Applications – Unit Selection

Achievingoptimalperformancewithwatersourceheatpump systems requires both accurate system design and proper equipment selection. Use a building load program to determinetheheatingandcoolingloadsofeachzonepriorto making equipment selections. With this information, the McQuay SelectTools™ software selection program for Water Source Heat Pumps can be used to provide fast, ac-curateandcompleteselectionsofallMcQuaywatersourceheatpumpproducts.SelectToolssoftwareisavailablebycontactingyourlocalMcQuayRepresentative.

Boiler / Tower Application Manual Selections:

Thefollowingexampleillustratesatypicalselectionfora zone in a boiler/tower system for a commercial building.

Abuildingloadprogramdeterminesthatthiszoneneeds10,430 BTUH of total cooling, 6,950 BTUH of sensible coolingand9,150BTUHoftotalheating.Thewatertem-peratures for the boiler/tower system are 90ºF for cooling and 70ºF for heating. The return air temperature is 80ºF dry bulb with 67ºF wet bulb for cooling and 70ºF for heating.

Zone Requirements: TotalCoolingLoad = 10,430BTUHSensible Cooling Load = 6,950 BTUH TotalHeatingLoad = 9,150BTUHAir Flow Required = 275 CFM Return Air Cooling = 80ºFDB/ 67ºFWB Return Air - Heating = 70ºFDB

SinceaMcQuayModelMHC009producesapproxi-

mately 10,000 BTUH of cooling, it is not sufficient for this zone and a model MHC 012 should be considered. Model MHC is chosen because it is specifically designed for a boiler/tower application. Typical water flow rates for boiler/tower applications are 2.0 to 2.5 GPM per ton and in thisexamplenoantifreezeisused.

Selection:Model.............................MHC 012 (Boiler / Tower model)

TotalCoolingCapacity@90EWT = 11,511BTUHSensible cooling capacity @ 90 EWT = 7,660 BTUH Total Heating Capacity @ 70 EWT = 14,160 BTUH CFM = 275Water Flow required to meet capacity = 8 GPM Water Pressure drop = 2.5 (FT. H2O)

FinalSelection....................................................MHC 012

Geothermal Applications:The following example illustrates the same zone in a

geothermalapplication.The load requirements for the zone are the same as the

above example – 10,430 BTUH of total cooling and 6,950 BTUH of sensible cooling and 9,150 BTUH of heating.Geothermal loop software programs are available to helpdetermine the size of the loop field based on:

Desiredenteringwatertemperaturesforthesystem. Specific acreage available for the loop which produces

specific min./max loop temps for the unit selection.

Enteringwatertemperaturesforgeothermalsystemscanbeashighas90ºto100ºFandaslowas30ºFbasedonthegeographical location of the building. Water flow rates are typically 2.5 to 3 GPM per ton and the use of antifreeze is required in most northern applications.

Zone Requirements: TotalCoolingLoad = 10,430BTUHSensible Cooling Load = 6,950 BTUH TotalHeatingLoad = 9,150BTUHAir Flow Required = 275 CFM Return Air Cooling = 80 DB / 67 WB Return Air - Heating = 70 DB

The Model MHW 012 is first considered but may not meettheheatingloadbecauseofthereducedenteringwatertemperatures (35ºF) and an antifreeze solution of 21 % propylene(seepage34).

Selection: Model..................................MHC 012 (Geothermal model)

Totalcoolingcapacity@100EWT =10,555BTUHx .980=10,344Sensible cooling capacity @ 100 EWT = 7,257 BTUH x .980 = 7,112 Total heating capacity @ 35 EWT = 9,430 BTUH x .975 = 9,240 Btuh CFM = 284Water Flow required to meet capacity = 2.4 GPM Water Pressure drop = 2.5 x 1.5 = 3.75 (FT. H2O)

FinalSelection....................................................MHC 012Note: In applications where the zone may be a corner office or have excessive glass area, the heating load could be greater than the heating output capacity of the MHC 012 model (say 7,800 BTUH). The choices are to upsize the unit to the next model available (015).

Additional Information for Initial Start-Up Only

Standard Range Units:Unitsaredesignedtostartinanambientof50ºF(10ºC),

with entering air at 50ºF (10ºC), with entering water at 70ºF (21ºC), with both air and water at the flow rates used in the ISO 13256-1 rating test, for initial start-up in winter.

Note: This is not a normal or continuous operating condition. It is assumed that such a start-up is for the purpose of bringing the building space up to occupancy temperature.
