In this study we investigated ways to reduce the amount of electric power consumed by residential air conditioners during the cycle-heating dehumidification operation. The indoor heat exchanger of an air conditioner is divided into a condensing part and an evaporating part. Cooled and dehumidified indoor air is heated by the heat released from the condensing part. To improve the dehumidification performance and reduce electric power consumption, we found the point at which the compressor worked with the Iowest input power. We did this by evaluating the relations between the coefficient of dehumidification performance (dehumidification performance/total input power) and the rotational speed of compressor. We found that the rotational speed required to obtain a high coefficient of dehumidification performance point is lower when the opening rate of the dehumidification vane is smaller.
