Formula for heat absorbed
WebWhat is the formula of cop? COP (Coefficient of Performance) COP is defined as the relationship between the power (kW) that is drawn out of the heat pump as cooling or heat, and the power (kW) that is supplied to the compressor. For example: A given heat pump used for air cooling has a COP = 2. What is the meaning of BTU HR?
