A refrigeration cycle device configured so as to be equipped with: a refrigeration circuit having a compressor, an indoor heat exchanger, a throttle device, and an outdoor heat exchanger, which are connected by refrigerant piping; an outside air temperature sensor used for detecting the outside air temperature; and a control device that executes a defrosting operation on the basis of the detection result from the outside air temperature sensor. The control device is equipped at least with a combined defrosting mode, wherein a hot gas defrosting operation is executed by supplying hot gas to the outdoor heat exchanger, said hot gas being discharged from the compressor without passing through the indoor heat exchanger, after which a reverse defrosting operation is performed to supply refrigerant that has passed through the indoor heat exchanger from the compressor to the outdoor heat exchanger. When the detection result from the outside air temperature sensor satisfies a preset condition, the combined defrosting mode is executed. |
