PROBLEM TO BE SOLVED: To acquire a heat pump cycle device which can more surely discharge a refrigerant leaked into a water circuit to the outdoors.SOLUTION: A heat pump cycle device includes: an outdoor unit having a refrigerant circuit which is configured by connecting a compressor for compressing a combustible refrigerant, an air heat exchanger for performing heat exchange between air and the refrigerant, a water heat exchanger for performing heat exchange between the refrigerant and water, and a throttle device for performing a pressure adjustment of the refrigerant flowing in the water heat exchanger via piping; and an indoor unit having a part of a water circuit for circulating circulation water for exchanging heat with the refrigerant and for conveying heat in the water heat exchanger. In the heat pump cycle device, outdoor unit has a pressure releasing valve for adjusting a water pressure in the water circuit on a wake flow side of the water heat exchanger in a flow direction of the water circuit.SELECTED DRAWING: Figure 1 |
