Coefficient of performance of a refrigerator
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. Web• Comparison of Coefficient of Performance (COP) 2. The coefficient of performance of a vapour compression refrigeration system operating on R- with SSTO and inclusion of SiO 290 has been improved by 15.9% by including a stepped short tube orifice. This performance coefficient is greater than the performance coefficient
