Abstract:
In a refrigeration cycle apparatus, a controller is configured to, when a defrost mode is started, control a first pressure reducing device is controlled to adjust a flow rate of refrigerant to bring a degree of superheat of the refrigerant at a suction side of a compressor close to a target value, control a flow path switching device to form a first flow path through which the refrigerant released from the compressor flows to a first heat exchanger; perform a refrigerant release operation of opening one of a second pressure reducing device and a valve and closing the other of the second pressure reducing device and the valve, and perform a refrigerant collection operation of opening the second pressure reducing device and the valve, with the flow path switching device retained to form the first flow path, after the refrigerant release operation.

Claim (Index 1):
A refrigeration cycle apparatus comprising:\n a compressor; a first heat exchanger; a second heat exchanger connected in series with the first heat exchanger and having a capacity smaller than the first heat exchanger; a first pressure reducing device connected between the first heat exchanger and the second heat exchanger; a flow path switching device configured to\n form a first flow path through which refrigerant released from the compressor flows to the first heat exchanger in a cooling mode and a defrost mode, and \n form a second flow path through which the refrigerant released from the compressor flows to the second heat exchanger in a heating mode; \n a refrigerant tank circuit\n branching from between the first heat exchanger and the first pressure reducing device and joining between the first pressure reducing device and the second heat exchanger, \n being in parallel with the first pressure reducing device, and \n including, in series, a second pressure reducing device, a refrigerant tank, and a valve, the valve opening and closing a flow path between the refrigerant tank and the second heat exchanger; and \n a controller configured to control the flow path switching device, the second pressure reducing device, and the valve, when the defrost mode is started, the first pressure reducing device being configured to adjust a flow rate of the refrigerant to bring a degree of superheat of the refrigerant at a suction side of the compressor close to a target value, the controller being configured to\n control the flow path switching device to form the first flow path, \n perform a refrigerant release operation of opening one of the second pressure reducing device and the valve and closing an other of the second pressure reducing device and the valve, and \n perform a refrigerant collection operation of opening the second pressure reducing device and the valve, with the flow path switching device retained to form the first flow path after the refrigerant release operation.
