Abstract:
A controller in a refrigeration cycle apparatus performs a refrigerant recovery operation when switching an operation mode from a defrosting mode to a heating mode. During the refrigerant recovery operation, by rotating a fan of a blower while monitoring a pressure at a discharge side of the compressor, the controller is configured to perform feedback control to cause a high-pressure side pressure to be close to a high-pressure side target pressure value. During the refrigerant recovery operation, by controlling a driving frequency of the compressor while monitoring a pressure at a suction side of the compressor, the controller is configured to perform feedback control to cause a low-pressure side pressure to be close to a low-pressure side target pressure value.

Claim (Index 1):
A refrigeration cycle apparatus comprising:\n a first heat exchanger; a second heat exchanger having a capacity smaller than a capacity of the first heat exchanger; a compressor; a decompressor; a flow path switch configured to form a flow path in which refrigerant circulates in a first circulation direction in order of the first heat exchanger, the decompressor, the second heat exchanger, and the compressor, or in a second circulation direction reverse to the first circulation direction; a blower configured to blow air to the first heat exchanger; a refrigerant tank circuit having a refrigerant tank and connected to the flow path; and a controller configured to switch an operation mode including a heating mode and a defrosting mode, in the heating mode, the flow path switch being controlled to form the flow path in which the refrigerant circulates in the second circulation direction, in the defrosting mode, the flow path switch being controlled to form the flow path in which the refrigerant circulates in the first circulation direction and the refrigerant tank circuit being controlled to release the refrigerant from the refrigerant tank to the flow path, when the operation mode is switched from the defrosting mode to the heating mode, a refrigerant recovery operation being performed to recover the refrigerant to the refrigerant tank while circulating the refrigerant in the first circulation direction, and the blower being operated during the refrigerant recovery operation.
