Abstract

The conditions that the air-conditioner changes the operation mode into the defrost cycle were clarified. 2.Based on the typical change of COP in a defrost mode, the method to estimate the energy consumption including defrost cycles was shown. 3.It was clarified the theoretical definition of the coefficients which correct the theoretical heat extraction based on the refrigerating cycle to the practical condition. The method to calculate the coefficients were also shown. 4.The distribution factors of COP in practical condition were analyzed, and the accuracy of the estimating method of COP proposed in our study was verified.
