ABSTRACT:
In a control apparatus of an air-conditioner in which a temperature difference between the room temperature and the set temperature is set into an input 1, a time-dependent change in the room temperature is set to an input 2, fuzzy arithmetic operations are executed in accordance with control rules by using membership functions of a membership function section 1, a switching amount of an operating frequency of a compressor 2 of an output is controlled on the basis of the results of the fuzzy arithmetic operations, and the operating frequency is switched at every predetermined interval (t seconds) thereby executing a room temperature control, during the operation, a room temperature (Tr) is always detected by a room temperature detecting section 4 and a change amount (Tr2-Tr1) of the room temperature is calculated in a room temperature change amount calculating section 5 each time of the detection, and when the calculated change amount exceeds a predetermined value, it is determined that the room temperature suddenly fluctuated, so that the fuzzy arithmetic operations are immediately executed and the operating frequency of the compressor 2 is switched.
