A refrigeration cycle apparatus includes a first temperature sensor 61 which detects a temperature of a refrigerant discharged from a compressor 21, and a control device 4. When an outlet temperature of a bypass passage 3 is a saturation temperature and a temperature detected by the first temperature sensor 61 is higher than a predetermined target temperature, the main expansion valve 24 is controlled in its opening degree-closing direction, and the temperature detected by the first temperature sensor 61 is lower than the predetermined target temperature, the main expansion valve 24 is controlled in its opening degree-opening direction. According to this, a discharge temperature can always be an appropriate temperature, and it is possible to obtain high operation efficiency and sufficient heating ability. |
