Abstract

An air conditioning system for a motor vehicle. The air conditioning system includes a refrigerant circuit divided into a high-pressure region and a low-pressure region, first and second internal heat exchangers arranged in the high-pressure and low-pressure regions, an external heat exchanger arranged in the refrigerant circuit, a condenser arranged in the high-pressure region, and an evaporator that, in a first operating mode, thermally couples the low-pressure region to the air conditioning air and, in a second operating mode, is arranged outside the refrigerant circuit.
