Abstract
A refrigeration cycle apparatus includes: a refrigerant circuit in which a compressor, a condenser, an expansion device, and an evaporator are connected by pipes, and refrigerant circulates; a high-pressure sensor that detects a pressure of the refrigerant on a discharge side of the compressor; a first temperature sensor that detects a temperature of the refrigerant on an outlet side of the condenser; and a controller that determines that the high-pressure sensor is abnormal, when the compressor is in operation and the temperature detected by the first temperature sensor is higher than a saturated liquid temperature or a saturated gas temperature that is calculated from the pressure detected by the high-pressure sensor.
