Abstract (en)
[origin: EP3951284A1] In a refrigeration cycle apparatus (100) according to the present disclosure, the circulation direction of refrigerant is switched between a first circulation direction and a second circulation direction opposite to the first circulation direction. The refrigeration cycle apparatus (100) includes a compressor (1), a first heat exchanger (4), a second heat exchanger (8), a third heat exchanger (6), a fourth heat exchanger (7), a first expansion valve (5A), and a second expansion valve (5B). The first circulation direction is a circulation direction in order of the compressor (1), the first heat exchanger (4), the first expansion valve (5A), the third heat exchanger (6), the fourth heat exchanger (7), the second expansion valve (5B), and the second heat exchanger (8). When a circulation direction of the refrigerant is the first circulation direction, the refrigerant from the third heat exchanger (6) exchanges heat with the refrigerant from the second heat exchanger (8) in the fourth heat exchanger (7). When a circulation direction of the refrigerant is the second circulation direction, the refrigerant from the fourth heat exchanger (7) exchanges heat with the refrigerant from the first heat exchanger (4) in the third heat exchanger (6).
