Abstract
A heat pump cycle device includes: a compressor; a branch portion; a heating unit configured to heat a heating object using one refrigerant branched at the branch portion as a heat source; a decompression unit configured to decompress the refrigerant flowing out of the heating unit; a bypass passage through which an another refrigerant branched at the branch portion flows; a regulating unit; and a joining portion. When a length of a suction-side flow path from an outlet port of the joining portion to a suction port of the compressor is defined as a suction-side flow path length L, the suction-side flow path length Lis equal to or longer than a relaxation distance Lv. The relaxation distance Lv is a flow length that is necessary for the refrigerant mixed in the joining portion to be made in a homogeneous state.
