An air conditioning system for a motor vehicle and method for operating an air conditioning system of a motor vehicle

The invention relates to an air-conditioning system (2; 102) for a motor vehicle, having an interior air conditioning module (38; 138) leading to at least two coolant cooling circuits (4, 6; 104, 106) of the motor vehicle via controllable or controllable valves (32, 52; 132, 152) is heat transporting connectable, wherein a regulation or control (64; 164) is provided which is adapted to control the controllable or controllable valves (32, 52; control 132, 152) such that one the cooling circuits (4, 6; 104, 106) with the higher temperature refrigerant to the indoor air conditioning module (38; 138) is heat transporting connectable. The invention further relates to a method for operating an air conditioning system (2; 102)
