Enter the heat output of the condenser and the power supplied by the compressor into the calculator to determine the COP.

## COP Formula

The following formula is used to calculate the coefficient of performance of a heat pump.

COP = | Q | / W

- Where COP is the coefficeint of performance
- Q is the heat output from the condenser (kWh)
- W is the power or work supplied by the compressor (kWh)

## COP Definition

**What is COP? **

COP stands for coefficient of performance. This is a term used to describe the ratio of useful heat output or removal by a heat pump and the work or power supplied by the compressor to the heat pump.

## Example Problem

**How is COP calculated? **

COP is calculated by dividing the absolute value of the total heat output or removal of a heat pump by the work or power supplied to the pump.

How to calculate COP?

**First, determine work or power supplied by the compressor to the heat pump.**For this example, the compressor is supplying 20 kWh.

**Next, determine the useful output or removal of heat by the pump.**In this case, the heat pump removes 30 kWh of heat.

**Finally, calculate COP.**Using the formula above, the COP is calculated to be:

COP = | Q | / W

COP = 30 / 20

COP = 1.5
