A refrigeration cycle device (100) is provided with: a refrigeration cycle circuit which has a compressor (1), a four-way valve (12), a heat source-side heat exchanger (14), a heat source-side pressure reduction mechanism (13), an indoor-side pressure reduction mechanism (7), and an indoor-side heat exchanger (9), and which, during cooling operation, connects the compressor (1), the four-way valve (12), the heat source-side heat exchanger (14), the heat source-side pressure reduction mechanism (13), the indoor-side pressure reduction mechanism (7), and the indoor-side heat exchanger (9) so that a refrigerant sequentially flow therethrough; and a hot water refrigerant circuit which is branched from between the compressor (1) and the four-way valve (12), has arranged sequentially therein a hot-water-side heat exchanger and a hot-water-side pressure reduction mechanism (6), and is connected between the heat source-side pressure reduction mechanism (13) and the indoor-side pressure reduction mechanism (7). When the refrigerant state value of the low-pressure side of the refrigerant cycle circuit and/or the discharge side of the compressor (1) is a refrigerant recovery start state value, refrigerant recovery operation is started, the refrigerant recovery operation recovering a refrigerant retained within the hot water refrigerant circuit into the refrigeration cycle circuit. |
