Note: The below default values are based on the “< 5 Ton Std Eff PTHP Comp, Cond, Evap” library member.
Cooling Mode
Speed <X> Ref. Rated Clg Capacity
|
Default: 38 Tons
|
|
Typical Range: 0 < X < 100,000,000,000,000
|
|
Min Max: N/A
|
|
Units: Btuh; kW; MBh; tons; W
|
This field defines the total, full load gross cooling capacity of the air-to-air cooling coil unit at rated conditions for speed <X> operation. Capacity should not account for supply air fan heat.
Speed <X> Ref. Rated Airflow
|
Default: 12,000 cfm
|
|
Typical Range: N/A
|
|
Min Max: 0.01 < X < 100,000,000,000,000
|
|
Units: ACH; cfm; L/s; m3/hr; m3/s
|
This field defines the airflow rate across the cooling coil at rated conditions for Speed <X> operation. The value entered here should be directly from the Reference Unit data, corresponding to the given cooling capacity and efficiency at the speed.
Speed <X> Ref. Rated Sensible Heat Ratio
|
Default: 0.7
|
|
Typical Range: N/A
|
|
Min Max: 0 < X < 1
|
|
Units: N/A
|
This field defines sensible heat transfer ratio (SHR = gross sensible cooling capacity divided by gross total cooling capacity) of the cooling coil unit at rated conditions for speed <X> operation. This value should be obtained from the Reference Unit data.
Speed <X> Ref. Rated Energy Rate
|
Default: 3.77 COP
|
|
Typical Range: N/A
|
|
Min Max: 0.11 < X < 1,000,000,000
|
|
Units: COP; EER; kW/kW; kW/MBh; kW/ton; MBh/ton; therms/(ton-hr)
|
This field defines the efficiency of the cooling coil unit at rated conditions for speed <X> operation. The input power includes power for the compressor(s), condenser fan and accessories, but does not include the supply air fan. The gross Reference Rated Energy Rate should not account for the supply air fan.
Heating Mode
Speed <X> Ref. Rated Heating Capacity
|
Default: 38 tons
|
|
Typical Range: N/A
|
|
Min Max: 0 < X < 100,000,000,000,000
|
|
Units: N/A
|
This field defines the total, full load gross heating capacity of the air-to-air heating coil unit at rated conditions for speed <X> operation. The gross heating capacity should not account for the effects of supply air fan heat.
Speed <X> Ref. Rated Airflow
|
Default: 12,000 cfm
|
|
Typical Range: N/A
|
|
Min Max: 0.01 < X < 100,000,000,000,000
|
|
Units: ACH; cfm; L/s; m3/hr; m3/s
|
This field defines the airflow rate across the heating coil at rated conditions for speed <X> operation. The value entered here should be directly from the Reference Unit data, corresponding to the given heating capacity and efficiency at the speed.
Speed <X> Ref. Rated Energy Rate
|
Default: 3.77 COP
|
|
Typical Range: N/A
|
|
Min Max: 0.11 < X < 1,000,000,000
|
|
Units: Units: COP; EER; kW/kW; kW/MBh; kW/ton; MBh/ton; therms/(ton-hr)
|
This field defines the efficiency of the heating coil unit at rated conditions for speed <X> operation. The input power includes power for the compressor(s), condenser fan and accessories, but does not include the supply air fan. The gross Reference Rated Energy Rate should not account for the supply air fan.
