A refrigeration cycle apparatus includes a first temperature sensor 61 which detects discharge temperature Td of refrigerant discharged from a compressor 21, a second temperature sensor 62 which detects evaporator outlet temperature Teo of refrigerant flowing out from an evaporator 25 in a refrigerant circuit 2, and a control apparatus 4. The control apparatus 4 adjusts an amount of refrigerant flowing through a bypass expansion valve 31 based on the discharge temperature Td and based on superheat degree SHe at the output of the evaporator 25 calculated from the evaporator outlet temperature Teo. According to this, optimal refrigerant flow rate distribution can always be secured, and it is possible to obtain high operation efficiency and sufficient heating ability. |
