特徴とする空気調和機。[Claims for Utility Model Registration] A refrigeration cycle is formed by sequentially connecting a compressor, a condenser, an expansion valve, and an evaporator, and when the refrigerant temperature discharged from the compressor reaches a set value, the expansion valve is opened. In an air conditioner equipped with a control unit that temporarily increases temperature, a detection means for detecting the temperature of the suction refrigerant is provided on the suction side of the evaporator, and the opening degree of the expansion valve is adjusted based on the temperature of the suction refrigerant. An air conditioner characterized in that it is controlled.
