Abstract
A device for heat distribution in a hybrid motor vehicle includes an engine cooling circuit and a refrigerant circuit for a combined operation in a refrigeration heat pump mode and a reheating mode. The refrigerant circuit includes an evaporator, a compressor, a heat exchanger to supply heat from the refrigerant to air being conditioned for a passenger compartment, and a heat exchanger to transfer heat between a refrigerant of the refrigerant circuit and coolant of the engine cooling circuit. The heat exchanger operates as an evaporator for the heat transfer from the coolant to the evaporating refrigerant, and alternatively operates as a condenser for the heat transfer from the condensing refrigerant to the coolant.
