Abstract:
A refrigeration cycle device (101) that circulates a refrigerant between a compressor (1), an indoor heat exchanger (3), an outdoor heat exchanger (6), a heat reservoir (5), a first expansion valve (4a), and a second expansion valve (4b). The refrigeration cycle device (101) comprises a bypass path (11) and a first opening/closing valve (41) provided to the bypass path (11). The bypass path (11) branches from a first portion (31, 32) of a first refrigerant piping (21), the first portion (31, 32) connecting the indoor heat exchanger (3) and the first expansion valve (4a), and reaches a fourth refrigerant piping (24) that connects an inlet of the compressor (1) and a four-way valve (2). The first opening/closing valve (41) is set to an open state during a defrosting operation.
