Abstract
A cooling device for a motor vehicle has a secondary circuit for transferring cold generated in an evaporator of a primary cooling circuit of a cooling unit, by means of a coolant, to at least one cold accumulator and/or to at least one heat exchanger for cooling the air fed to a vehicle interior. The secondary circuit has a control and distribution unit that feeds a first fraction of coolant flow, the level of which can be adjusted, to the cold accumulator, and a second fraction of coolant flow, the level of which can also be adjusted, to the heat exchanger. The cooling device allows optimum use of the cold accumulator during standard air-conditioning or in the peak load range, improves passenger comfort in the vehicle, and prevents frosting of the heat exchanger.
