Abstract

See full text

In a refrigeration cycle apparatus, a switching mechanism includes a first channel and performs switching among a first, second and third connection states. In the first connection state, the refrigeration cycle apparatus repeatedly performs a first cycle in which refrigerant flows through a compressor, a first heat exchanger, a second heat exchanger, and the compressor in that order. In the second connection state, the refrigeration cycle apparatus repeatedly performs a second cycle in which refrigerant flows through the compressor, the second heat exchanger, the first heat exchanger, and the compressor in that order. In the third connection state, a passage between the compressor and the first heat exchanger and a passage between the compressor and the second heat exchanger are closed, and the first channel in the refrigeration cycle apparatus provides interconnection between the first heat exchanger and the second heat exchanger.
