Title: HEAT PUMP DEVICE
Abstract:
A pressure-regulating valve is disposed in this heat pump device having: a refrigerant circuit in which a compressor, a heat source heat exchanger, an expansion mechanism, and an intermediate heat exchanger are sequentially connected via piping and through which a refrigerant is circulated; and a fluid circuit in which an intermediate heat exchanger, a load heat exchanger, and a check valve are sequentially connected via piping and through which a fluid is circulated. The pressure-regulating valve is connected to piping for connecting between an outlet of the intermediate heat exchanger and an inlet of the load heat exchanger in the fluid circuit. The pressure-regulating valve is configured to shut off the flow channel for the fluid in the case when fluid pressure increases as a result of refrigerant leakage into the fluid.
