What is the formula for Refrigeration COP Calculator (COP=Qc/W)?

Core formula: COP = Qc / W. The tool returns results instantly using this formula and the selected parameters.

Refrigeration COP Calculator (COP=Qc/W)

Compute the refrigeration coefficient of performance COP = Qc/W: given cooling capacity and work input, output the COP and heat rejected to the hot side.

Key points

Refrigeration COP Calculator (COP=Qc/W): Compute the refrigeration coefficient of performance COP = Qc/W: given cooling capacity and work input, output the COP and heat rejected to the hot side. Formula: COP = Qc / W. Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Refrigeration COP = Qc/W = cooling capacity / work input, usually greater than 1; larger values save more energy. Household air conditioners have COP ≈ 2.5–4 (EER/SEER); the theoretical limit of vapor-compression refrigeration is the Carnot COP.

Inputs

COP = Qc / W

Calculation model (updates with parameters)

Refrigeration COP	2	COP = Qc / W
Heat rejection Qh	3 kWW	Qh = Qc + W (rejected to the hot side)
Cooling capacity (watts)	2 kWW
Input power (watts)	1 kWW

Engineering notes

Refrigeration COP = Qc/W = cooling capacity / work input, usually greater than 1; larger values save more energy.
Household air conditioners have COP ≈ 2.5–4 (EER/SEER); the theoretical limit of vapor-compression refrigeration is the Carnot COP.
Heat rejection Qh = Qc + W: the condenser must remove the cooling capacity plus the compressor work.
