Document Type and Number:
WIPO Patent Application WO/2023/095418
Kind Code:
A1
Abstract:
Provided is a heat medium circulation device comprising a heat source-side circuit 20, an outdoor blower 26, a utilization-side circuit 30, and an electrical box 27, wherein: a combustible refrigerant is enclosed in the heat source-side circuit 20; a heat medium is enclosed in the utilization-side circuit 30; the combustible refrigerant and the heat medium flow to the intermediate heat exchanger 23; heat medium piping 31 has at least a gas discharge device 50 made of an air vent valve 51 and a pressure relief valve 52; the gas discharge device 50 is stored in a space C; the space C and the electrical box 27 are isolated from each other by at least one partition wall, thereby reducing the risk that the electrical box 27, which has a high risk as an ignition source, ignites, and further improving safety in an outdoor unit 11 formed from the heat source-side circuit 20 using the combustible refrigerant, the refrigerant/heat medium heat exchanger 23, and the air vent valve 51 or pressure relief valve 52, which is a part of the utilization-side circuit 30.
