Abstract

A cooling system with a heat pump function for a motor vehicle is described, includes a base system with a refrigerant compressor. A directly or indirectly working external heat exchanger which is arranged downstream of the refrigerant compressor. A directly or indirectly working first evaporator as part of an air conditioning device for the interior air conditioning of the motor vehicle, arranged down-stream of the external heat exchanger and preceded by a first expansion element. At least one second evaporator as part of a cooling device of an electric drive or storage unit, which evaporator is arranged fluidically parallel to the first evaporator, and which is preceded by a second expansion element. At least one low-pressure side collector arranged downstream of the first and second evaporators, or at least one high-pressure side collector arranged downstream of the external heat exchanger and upstream of the first and second evaporators.
