COEFFICIENT OF PERFORMANCE OF ROOM AIR CONDITIONER WITH VARIABLE CAPACITY COMPRESSOR

Abstract

In this paper, we evaluated the COP of room air-conditioners with variable capacity compressor. The evaluation method and process to lead functions of electricity consumption and cooling / heating output were shown. Coefficients to lead approximate functions of input and output were shown as well.
Next, we compared the COP calculated by functions mentioned above and the COP measured in another test institution. As a result, it was confirmed that evaluation COP was identical with measurement COP. It developed that annual electricity consumption of variable-capacity air-conditioners was less than that of popular air-conditioners, because the COP at partial load was high.
