Abstract

A refrigeration cycle apparatus includes: a compressor; a condenser; an expansion valve; an evaporator; and a control device. The compressor compresses refrigerant. The condenser condenses the refrigerant output from the compressor. The expansion valve decompresses the refrigerant output from the condenser. The evaporator evaporates the refrigerant output from the expansion valve for output to the compressor. In the case of stopping the compressor, the control device executes control for increasing a degree of superheat of the refrigerant output from the evaporator to the compressor, and then stops the compressor.
