Abstract (en)
[origin: EP4151926A1] A refrigeration cycle apparatus (100) comprises a refrigerant circuit (C1) and a refrigerant storage circuit (C2). In the refrigerant circuit (C1), a compressor (1), an outdoor heat exchanger (2), an expansion valve (3), and an indoor heat exchanger (4) are connected together by a pipe (P). The pipe (P) has a first pipe portion (P1) and a second pipe portion (P2). The first pipe portion (P1) connects the outdoor heat exchanger (2) to the expansion valve (3). The second pipe portion (P2) connects the indoor heat exchanger (4) to the compressor (1). The refrigerant storage circuit (C2) has a storage container (12), an expander (13), and a valve device (11). The storage container (12) stores refrigerant. The expander (13) is located between the storage container (12) and the second pipe (P2). The valve device (11) is located between the first pipe (P1) and the expander (13). The valve device (11) is configured to open and close the refrigerant storage circuit (C2).
