Beschreibung
Zusammenfassung:	According to one embodiment, a refrigeration cycle apparatus includes a main flow channel of a refrigerant, a compressor, a condenser, an evaporator, a branch channel, an expansion valve, a supercooling heat exchanger, an injection flow channel, and a control unit. The control unit determines, based on whether the determination condition is satisfied or not, a determination condition for adjusting an opening degree of the expansion valve and adjusts the opening degree of the expansion valve according to a first target value for a discharge temperature of the refrigerant from the compressor, or a second target value for a superheat degree of the refrigerant flowing through the injection flow channel.
