This refrigeration cycle device (1) is provided with: a first circulation circuit (11) in which a first compressor (21), a first radiator (22), a first decompression device (24), and a first evaporator (25) are connected in the given order, and that circulates a refrigerant via a retention vessel (23) having a space retaining the refrigerant; and a bypass duct (12) that interconnects the bottom of the space of the retention vessel (23) and a portion between the first compressor (21) and the first evaporator (25) of the first circulation circuit (11). The retention vessel (23) is connected between the first evaporator (25) and the first radiator (22) at the side of the first circulation circuit (11) to which the first decompression device (24) is connected, and the refrigerant retained in the space of the retention vessel (23) is retained in the state of being mixed with an incompatible oil, and is cooled by a cooling means. |
