Abstract (en)

[Object] It is an object of the present invention to provide a heat medium circulation device capable of placing a gas-liquid separating section and a pressure relief valve in a limited space.[Solving means] A heat medium circulation device of the present invention including: a refrigerant circuit 10 to which a compressor 11, a use-side heat exchanger 12, an expansion device 13 and a heat source-side heat exchanger 14 are connected, and through which refrigerant circulates; a heat medium circuit 20 which circulates heat medium cooled or heated by the refrigerant discharged out from the compressor 11 in the use-side heat exchanger 12 through a use-side terminal 1; a gas-liquid separating section 30 for separating gas in the heat medium circuit 20 from the heat medium; and a pressure relief valve 40 for releasing the heat medium circuit 20 into atmosphere when pressure in the heat medium circuit 20 becomes equal to or higher than predetermined pressure; wherein the pressure relief valve 40 is connected to the gas-liquid separating section 30.
