Classification: CPC F  Y | IPC F

Claim 0:
1. A refrigeration cycle apparatus comprising:
a compressor;
an indoor heat exchanger;
an outdoor heat exchanger including a first outdoor heat exchanger and a second outdoor heat exchanger;
a bypass flow passage configured to cause a discharge side of the compressor to communicate with the first outdoor heat exchanger or the second outdoor heat exchanger;
a flow control valve provided at the bypass flow passage; and
a controller configured to perform a heating operation and a simultaneous heating and defrosting operation, the heating operation being an operation in which the first outdoor heat exchanger and the second outdoor heat exchanger are each caused to operate as an evaporator and the indoor heat exchanger is caused to operate as a condenser, the simultaneous heating and defrosting operation being an operation in which part of refrigerant discharged from the compressor is supplied to one of the first outdoor heat exchanger and the second outdoor heat exchanger through the bypass flow passage, the other of the first outdoor heat exchanger and the second outdoor heat exchanger is caused to operate as an evaporator, and the indoor heat exchanger is caused to operate as a condenser,
wherein the controller is configured to change, when the simultaneous heating and defrosting operation is performed, an upper limit frequency of the compressor to a value higher than the upper limit frequency of the compressor in the heating operation,
wherein the upper limit frequency of the compressor is an upper limit value of an operation frequency range of the compressor.
