実使用時のルームエアコンデイショナのCOP 評価: ルームエアコンデイショナの冷暖房COP およびエネルギー消費量に関する研究　その3

摘要

本報ではまず、既報で提示したCOP推定法において課題でrnあった除霜時のCOP補正方法を検討した。次に、冷凍サイクルをrn基にした理論入能力を、実働入能力に修正するために必要な各係数rnの理論的定義と算出法を示し、理論入能力から求める実働COPのrn算出式を再定義した。%1. The conditions that the air-conditioner changes the operation mode into the defrost cycle were clarified.rn2. Based on the typical change of COP in a defrost mode, the method to estimate the energy consumption including defrost cycles was shown.rn3. 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.rn4. 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
