家庭用エアコンの実使用時における成績係数に関する研究 : 独立戸建住宅13棟に設置されたエアコンの測定結果 STUDY ON THE PERFORMANCE OF HOUSEHOLD AIR-CONDITIONER IN THE PRACTICAL USE : Results of COP on a air-conditioner at 13 detached houses

This paper describes the characteristic of coefficient of performance (COP) of a household air-conditioner. We measured 13 air-conditioners installed in residences in Niigata by the simplified COP measurement technique. The results are as follows. (1) There are big difference between the actual COP and the catalog COP. Actual COP is higher than catalog COP for a cooling, and actual COP is lower than catalog COP for a heating period. (2) In this study, heating capacity of the air-conditioner is relatively smaller than cooling capacity. (3) Actual COP of heating period is smaller than actual COP of cooling period.
