Water-to-Water Heat Pump
The heat pump has a reciprocating compressor that serves both the hot water and the chilled water loop.
Rated Cooling Capacity
|
Default: Autosize
|
|
Typical Range: 50 to 500 tons
|
|
Min Max: 0 < x < 999,999
|
|
Units: tons, W, kW, Btuh, Mbh
|
This field specifies the rated cooling capacity of the heat pump.
Rated Cooling Power Consumption
|
Default: 0.44 kW/ton
|
|
Typical Range: 0.4 to 0.5 kW/ton
|
|
Min Max: 0 to 999,999
|
|
Units: kW/ton, therms/ton-hr, Mbh/ton, kW/Mbh, kW/kW, COP, EER
|
This numeric input field is the heat pumps’ rated electric power consumption.
Sizing Factor
|
Default: 100%
|
|
Typical Range: 10 to 100%
|
|
Min Max: 0 to 999,999
|
|
Units: %
|
The sizing factor is used when the capacity is selected as auto sized. The autosizing calculations are performed as usual and the results are multiplied by the sizing factor.
