Heat Pump Performance: air_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) |
|---|---|---|---|---|---|
| air_source_cooling | 65 | 1.2 | 5 | Air-source cooling at 65F ambient — shoulder season; condensing conditions very favorable; capacity fraction exceeds rated (slightly over-produces); COP significantly elevated | 4.22 |
| air_source_cooling | 75 | 1.08 | 4.3 | Air-source cooling at 75F ambient; below rated 95F outdoor condition; COP and capacity fraction improve as condenser delta-T falls | 4.42 |
| air_source_cooling | 85 | 1.1 | 3.8 | Cooling at lower ambient; capacity and efficiency both improve | 5.09 |
