Abstract

PURPOSE:To enable to enhance the dehumidifying function of an air-conditioner at the time of its space-cooling cycle, by controlling the air-flow rate of an indoor fan to a minimum level not causing frosting of a heat exchanger by detecting the temperature of vaporization of the heat exchanger. CONSTITUTION:When the level of the temprature detected by a sensor 1 for detecting the temperature of vaporization of an indoor heat exchanger becomes lower than a preset temperature, a micro computor 3 increases the speed of rotation of an indoor fan motor by shortening the time set in a phase control angle output timer. On the other hand, when the detected temperature becomes higher than the preset temperature, the micro computer 3 decreases the speed of rotation of the indoor fan motor by prolonging the time set in the phase control angle output timer.
