MODULAR DESIGNED HIGH PERFORMANCE HEAT PUMP SYSTEM FOR A VEHICLE WITH LOW WASTE HEAT RADIATION

摘要

An air conditioning system for conditioning air of a passenger compartment of a motor vehicle. The air conditioning system operable in a cooling mode, a heat pump mode, and a reheating mode, the system includes an enclosure with a first flow channel and a second flow channel conducting air, and a refrigerant circulation system with a heat exchanger operable as an evaporator independent of the operating mode and a heat exchanger operable as a condenser independent of the operating mode. Both heat exchangers are located inside the enclosure. The refrigerant circulation system also includes a heat exchanger outside of the enclosure and inside the refrigerant path, an expansion element upstream from the evaporator in the flow direction of the refrigerant, and a bypass parallel to the refrigerant path to channel the refrigerant around the heat exchanger as needed.
