Heat Pump Performance: water_source_cooling
Heat pump COP and capacity fraction data as a function of outdoor temperature (air-source) or entering water temperature (ground/water-source) — covers air-source heating/cooling, cold-climate ASHP, ground-source, and water-source heat pumps
| heat pump type | outdoor temp F | capacity fraction (dimensionless) | cop (dimensionless) | notes | power input kW (kW) |
|---|---|---|---|---|---|
| water_source_cooling | 60 | 1.06 | 6.2 | WSHP cooling; EWT 60F; low loop temperature — heating-dominated system; excellent cooling efficiency; heat rejected to loop supports heating elsewhere in building | 3.01 |
| water_source_cooling | 65 | 1.03 | 5.7 | WSHP cooling; EWT 65F; typical shoulder season loop temperature; good COP — better than air-cooled at 95F ambient by large margin | 3.18 |
| water_source_cooling | 70 | 1.01 | 5.4 | WSHP cooling; EWT 70F; mid-range loop temperature; system approaches balance point — simultaneous heating and cooling loads | 3.29 |
