Heat Pump Performance: air_source_heating_coldclimate
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_heating_coldclimate | -13 | 0.5 | 1.5 | Minimum rated operating temp for many NEEP-listed cold-climate ASHP | 5.86 |
| air_source_heating_coldclimate | -5 | 0.57 | 1.9 | Cold-climate ASHP at -5F; Mitsubishi MXZ Hyper Heat / Zuba-Central maintains operation; COP 1.8-2.1 at this temperature; capacity fraction 55-60% relative to 47F rated output | 5.28 |
| air_source_heating_coldclimate | 5 | 0.65 | 2.2 | Cold-climate ASHP maintains functionality at extreme low temps | 5.2 |
