Abstract

To provide an air conditioner including a refrigerant circuit formed by connecting a compressor (3), a condenser, a restriction device, and an evaporator to each other. When the amount of refrigerant circulating through the refrigerant circuit is large, the air conditioner performs suction superheat degree control which operates the restriction device on the basis of the suction temperature of the refrigerant sucked by the compressor (3). When the amount of refrigerants circulating through the refrigerant circuit is small, the air conditioner performs suction superheat degree control until the refrigeration cycle is stabilized. After the refrigeration cycle is stabilized, the air conditioner performs discharge superheat degree control which operates the restriction device on the basis of the discharge temperature of the refrigerant discharged from compressor (3). Thereby, the air conditioner can perform efficient air conditioning operation irrespective of the amount of refrigerant circulating through the refrigerant circuit.
