Coefficient of performance of a refrigerator
WebCoefficient of Performance: This coefficient of performance (COP) calculator calculates the ratio of heating or cooling provided to work required. The most basic formula to COP is Q/W, where Q is the heat … WebWhat is the coefficient of performance? Solution The coefficient of performance or COP of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required. Higher COPs equate to lower operating costs. Suggest Corrections 6 Similar questions Q. What is the coefficient of performance? Q.
