PROBLEM TO BE SOLVED: To provide a heat distribution device for a vehicle, especially for a hybrid vehicle.SOLUTION: A heat distribution device 1 includes engine cooling circuit 3, 3' and a refrigerant circuit 2 for a combined operation of a refrigeration system mode and a refrigeration heat pump mode, and for a reheating mode, including an evaporator 4, a compressor 5, a heat exchanger 6 to supply heat from a refrigerant to air being conditioned for a passenger compartment, and a heat exchanger 9 to transfer heat between a refrigerant of the refrigerant circuit 2 and the engine cooling circuits 3, 3'. The heat exchanger 9 is arranged and structured so as to operate as an evaporator for heat transfer from the coolant to the refrigerant being evaporated, and as a condenser for heat transfer from the condensing refrigerant to the coolant. On the other hand, the engine cooling circuits 3 and 3' have a first motor 14 and a second motor 17, the first motor 14 is an internal combustion engine, and the second motor 17 is an electric motor. |
