Abstract:
1. Air conditioning system for a motor vehicle, which air conditioning system is designed for an air conditioning operating mode and at least one of a heat pump operating mode and a reheat operating mode, said air conditioning system comprising: a refrigerant cycle with a compressor, a refrigerant cooler and a supply air/refrigerant heat exchanger, said supply air/refrigerant heat exchanger being disposed in a supply air channel and functioning as an evaporator in an air conditioning operating mode, a coolant cycle for cooling a heat generating vehicle component including a first coolant cooler for cooling an internal combustion engine of said motor vehicle, a refrigerant/coolant heat exchanger, coupling the refrigerant cycle and the coolant cycle so as to transfer heat, refrigerant flow control valves for controlling mode-dependent flow of the refrigerant so as to be guided in an air conditioning mode from the compressor over the refrigerant cooler to the supply air/refrigerant heat exchanger, and an internal combustion engine exhaust gas/coolant heat exchanger connected upstream in series to the refrigerant/coolant heat exchanger in the coolant cycle and connected downstream in series with the first coolant cooler of the internal combustion engine.
