Heat Pump COP

Ideal efficiency of a heat pump running in heating mode.

Formula

COP = \frac{T_h}{T_h - T_c}

Variables

COPHeating COP

T_hHot side (K)

T_cCold side (K)

Example

T_h=293, T_c=273: COP = 293/20 = 14.65

Did You Know?

Heat pumps can deliver more than one unit of heat per unit of electricity, unlike a resistive heater capped at COP 1.

Sensible Heat Load

Heat needed to change air or water temperature without a phase change.

Latent Heat Load

Heat absorbed or released when moisture condenses or evaporates — the hidden load air conditioners fight.

Coefficient of Performance (Cooling)

Cooling delivered per unit of work input — higher is more efficient.

Energy Efficiency Ratio (EER)

Cooling capacity in BTU/h per watt of power — a common AC rating.

Refrigeration Tons

Cooling capacity in tons, where one ton removes 12,000 BTU/h.

Airflow (Sensible)

Air volume flow needed to carry a sensible heat load (imperial units).
