Abstract

A refrigeration cycle device includes a compressor to compress refrigerant, a suction-side detector to detect a pressure of the refrigerant to be suctioned into the compressor, a discharge-side detector to detect a pressure of the refrigerant discharged from the compressor, and controlling circuitry that controls the compressor. When the ratio of a second pressure value detected by the discharge-side detector to a first pressure value detected by the suction-side detector is not between a predetermined upper limit and a predetermined lower limit, the controlling circuitry controls the compressor such that the ratio falls between the predetermined upper limit and the predetermined lower limit.
