する空気調和機の制御装置。 Variable capacity compressor, outdoor heat exchanger, pressure reduction device,
A refrigerant circuit formed by sequentially connecting outdoor heat exchangers,
In an air conditioner equipped with a control unit that detects the indoor temperature and controls the operation of the compressor, and also detects the overload state of the compressor using a temperature sensor installed in the indoor heat exchanger and performs overload protection. The control unit is equipped with a timer that starts counting at the same time as the first overload protection is activated, and a counter that counts the number of overload protection operations that are repeated during the same timer operation, so that the overload protection is not repeated within a preset time. A control device for an air conditioner, characterized in that the maximum allowable frequency of a compressor is set in stages according to the number of times overload protection is activated.
