Abstract (en)
A heat medium circulation device 100 of the present disclosure including: a refrigerant circuit 110 which is formed by annularly connecting a compressor 111, a use-side heat exchanger 112, an expanding device 113 and a heat source-side heat exchanger 114 to one another; and a mechanical chamber 130 in which a portion of at least the refrigerant circuit 110 and a control device 120 are accommodated, in which flammable refrigerant is used as working fluid, wherein the heat medium circulation device 100 further includes an open/close mechanism 140 which opens such that an interior of the mechanical chamber 130 is vented into the outdoor atmosphere when the flammable refrigerant leaks into the mechanical chamber 130. Therefore, it is possible to lower the ignition risk when the flammable refrigerant leaks while securing energy saving performance and noise barrier performance.
