Abstract
A refrigeration cycle apparatus includes a refrigeration cycle circuit that has a compressor, a condenser, an expansion device, and an evaporator that are connected through a pipe, the refrigeration cycle circuit being configured to allow refrigerant to circulate in the refrigeration cycle circuit, and a controller configured to determine whether the refrigerant leaks or whether the expansion device malfunctions on the basis of a degree of subcooling at an outlet of the condenser and a degree of superheat at an outlet of the evaporator or a degree of superheat at a suction port of the compressor.
