PURPOSE:To reduce the frequency of fluctuation of the r.p.m. of an indoor fan and keep a pleasant temperature by a method wherein a time to arrive at a set temperature value determined by the magnitude of air-conditioning load is taken into consideration. CONSTITUTION:A phase control unit 13 is varied continuously within the output voltage range of 50-100V and the r.p.m. of the indoor fan 14 changes within the range of 800-1,800r.p.m. A control unit 15 operates the load 18 by receiving as inputs to the microcomputer the operation signal of operating unit 16 of the air conditioner and the temperature data of a room temperature sensor 17, provides a phase control unit 13 with a voltage setting signal and operates the indoor fan 14 at the same time. The control unit 15 detects a difference between the detecting temperature of the room temperature sensor 17 and the set temperature of a temperature setter 19 at the time of starting the fan 14 by a temperature difference detecting unit 20 and receives the data signal of a time detecting unit 21 which detects the time required for arriving at the set temperature, outputs a voltage setting signal for a plural zones corresponding to the arriving time whereby the control of r.p.m. of the indoor fan 14 based on the air-conditioning load may be performed. |
