Abstract: Provided are branch part (103) that distributes a refrigerant having flowed out of condenser (104) into main circuit (130) communicating with evaporator (108) and bypass circuit (140) that bypasses evaporator (108), confluence part (112) that merges the refrigerant from main circuit (130) and the refrigerant from bypass circuit (140), first throttle (106) that decompresses and expands the refrigerant between condenser (104) and evaporator (108), first inter-refrigerant heat exchanger (114) that exchanges heat between the refrigerant between condenser (104) and first throttle (106), and the refrigerant between confluence part (112) and suction into compressor (102), second throttle (110) that is disposed in bypass circuit (140), and decompresses and expands the refrigerant distributed at branch part (103), and second inter-refrigerant heat exchanger (111) that is disposed in bypass circuit (140) and exchanges heat between the refrigerant decompressed and expanded by second throttle (110) and the refrigerant having flowed out of the condensation-side outlet of first inter-refrigerant heat exchanger (114).
