Abstract (en)
A refrigeration cycle apparatus (1) includes: a compressor (13) in a first refrigerant path (F1) between a first heat exchanger (11) and a second heat exchanger (12); a first flow rate adjustment device (14) in a second refrigerant path (F2) between the first heat exchanger (10) and the second heat exchanger (12); a refrigerant storage device (16) provided in a third refrigerant path (F3) between the first heat exchanger (11) and the second heat exchanger (12), connected in parallel with a part of the second refrigerant path (F2), and configured to store refrigerant flowing from the second refrigerant path (F2); a second flow rate adjustment device (18) provided in the third refrigerant path (F3), and configured to adjust a flow rate of refrigerant between the refrigerant storage device (16) and the second refrigerant path (F2); and a controller (100) configured to control the second flow rate adjustment device (18) to block flow of refrigerant from the second refrigerant path (F2) into the refrigerant storage device (16) when cooling operation is started.
