  • the refrigerant cooled by the outdoor heat exchanger 43 is decompressed by the decompression device 44, and then flows into the refrigerant flow path of the plate heat exchanger 2 and exchanges heat with the water in the water flow path of the plate heat exchanger 2.
  • the water cooled by exchanging heat with the refrigerant in the refrigerant circuit 70 in the plate heat exchanger 2 circulates in the heating / cooling water circuit 80, is supplied to, for example, the fan coil unit 60, and is used for cooling.
  • a heat pump device having high heat exchange efficiency can be configured.
