Abstract

In an air-conditioning system for a motor vehicle having an integrated heat pump for cooling and heating, in which refrigerant is circulated and which allows heat exchange with the incoming air for the interior compartment of the motor vehicle, the heat transfer is effected either directly, by means of a refrigerant/air heat exchanger through which the air for the interior compartment is conducted, or by means of a secondary refrigerant circuit, which includes two expansion devices and three heat exchangers provided in the refrigerant circuit of the system.
