る制御手段を具備したことを特徴とする空気調和機。An air conditioner comprising a heat pump type refrigeration cycle in which a compressor, a condenser, an electric expansion valve, an evaporator, etc. are connected in sequence, and the degree of opening of the electric expansion valve is controlled according to the degree of superheating of the refrigerant in the evaporator. In the machine, during defrosting operation, the opening degree of the electric expansion valve is set to a larger opening degree than the opening degree corresponding to the degree of superheating of the refrigerant, and after the defrosting operation is completed, the opening degree of the electric expansion valve is set to a degree larger than the opening degree corresponding to the degree of superheating of the refrigerant. An air conditioner characterized by comprising a control means for setting the opening degree to the opening degree before the start of defrosting operation for a certain period of time.
