A refrigeration cycle apparatus includes: an electric compressor that compresses and discharges refrigerant; a heating heat exchanger that heats a fluid by high pressure refrigerant discharged from the electric compressor as a heat source; a decompressor that decompresses the refrigerant flowing from the heating heat exchanger; an evaporator that evaporates the refrigerant decompressed by the decompressor; and a rotational speed controller that controls a rotational speed of the electric compressor. The rotational speed controller is configured to reduce an upper limit value of the rotational speed of the electric compressor in accordance with an increase in a pressure ratio of a high-pressure side refrigerant pressure of refrigerant within a range from a discharge port of the compressor to an inlet side of the decompressor to a low-pressure side refrigerant pressure of refrigerant within a range from an outlet side of the decompressor to a suction port of the compressor.
