Abstract: An air-conditioning system is provided for an automobile comprising an interior air-conditioning module, which can be connected in a heat-transporting manner to at least two coolant-carrying cooling circuits of the automobile via valves (e.g., controllable or adjustable valves). A controller is also provided that is configured to control the valves in such a manner that those cooling circuits having the higher coolant temperature can be connected in a heat-transporting manner to the interior air-conditioning module. A method is also provided for operating an air-conditioning system.

Abstract: A charge air cooling device is provided for a combustion engine with a first heat exchanger configured to transmit thermal energy of a charge airflow to a coolant and with a second heat exchanger by which thermal energy of the coolant can be discharged into the surroundings. The first heat exchanger is designed as coaxial tube heat exchanger, which directly connects a compressor provided for the combustion air to the engine.
