Cooling Only Heat Pump SHC
Notes:
1. SHC - Simultaneous Heating and Cooling Heat Pump
2. Unit tonnage and efficiency at AHRI rating conditions: 44°F leaving chilled water temperature, 95°F entering condenser air temprature, flow rate is
2.4 GPM per ton through the evaporator with a .0001 fouling factor.
3. Module operational weight includes water, compressor oil, and refrigerant charge. Multiply times the number of modules for a
total system operational weight.
4. Unit shipping weight includes refrigerant charge, compressor oil and packaging; based on transportation.
5. Main header water/fluid connections are ASME, 6" scheduled 40 pipe with grooved couplings, 300 psig manimum working pressure.
