    摘要: 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.

    摘要: The invention relates to a device for cooling a vehicle interior with a secondary circuit (26) for transferring the cold produced in an evaporator (24) of a primary refrigerating circuit (14) of a refrigerating unit (12) by means of a refrigerating medium to at least one heat transfer device (34) for cooling the air to be fed into the vehicle interior, the secondary circuit (26) having a main circuit (36) and an auxiliary circuit (40) containing the heat transfer device (34), which are coupled by a four-way valve (56), by means of which an adjustable proportion of the flow of refrigerating medium can be diverted from the main circuit (36) and fed into the auxiliary circuit (40). In order to provide an improved device for cooling, in particular one that can be produced at a more reasonable cost, it is proposed that an inner heat exchanger (80) should be provided in the auxiliary circuit (40), allowing heat exchange to take place between a feed (60) and a return (62). This makes it possible to dispense with the use of a circulation pump in the auxiliary circuit.
