PROBLEM TO BE SOLVED: To increase refrigerating capacity by remarkably lowering pressure loss in a compressor suction line without abolishing a refrigerant auxiliary evaporator and a bypass circuit in a GHP having the refrigerant auxiliary evaporator for engine waste heat recovery in the compressor suction line of a refrigerant circuit. SOLUTION: Ports of an accumulator 27 as equipment forming the refrigerant circuit 20 of the GHP includes an outflow port allowing gas refrigerant to flow to a compressor 21, an inflow port allowing the refrigerant passed through the refrigerant auxiliary evaporator 28 for waste heat recovery to flow therein, and an inflow port allowing the refrigerant flowing through a bypass tube 29 bypassing the refrigerant auxiliary evaporator 28 to flow therein. By this, a pressure loss at the downstream end of the bypass tube 29 can be reduced by allowing the refrigerant bypassing the refrigerant auxiliary evaporator 28 to flow directly in the accumulator 27 without merging with the other pipes.
