Abstract

A climate control system for conditioning air of a motor vehicle passenger compartment and a method for operating same includes a climate control unit with a housing with a first flow channel and a second flow channel for conducting air, a refrigerant circulation and first and second coolant circulation. Refrigerant circulation is implemented with refrigerant-air heat exchanger operable as evaporator independently of operating mode Refrigerant-air heat exchanger is disposed within housing of the climate control unit. First refrigerant-coolant heat exchanger operates as condenser/gas cooler independently of operating mode. Second refrigerant-coolant heat exchanger operates as evaporator independently of the operating mode are disposed outside of housing of climate control unit. First coolant circulation comprises second refrigerant-coolant heat exchanger and heat exchangers for conditioning components of power train and a battery heat exchanger. Second coolant circulation is implemented with first refrigerant-coolant heat exchanger and with heating heat exchanger disposed within the housing of the climate control unit.
