Abstract
A device for air-conditioning the passenger compartment and for cooling the drive system of electric vehicles includes an air-guide duct connected on the inlet and outlet sides to the passenger compartment and having heat exchangers disposed one behind the other therein in the air-flow direction. One of the heat exchangers, which, together with a circulating pump and a cold store, is incorporated within a circuit of a cold-transporting medium. The circuit is run via the evaporator of a refrigeration unit. The other heat exchanger, together with a circulating pump and a heat store, is incorporated within a circuit of a heat-transporting medium. The circuit is run via the drive system of the electric vehicle for vehicle-cooling purposes. With the aim of reducing the weight of the device without altering the storage capacity of the cold and heat stores, these are formed by a single energy store, which, by at least one switchover valve, can be switched alternately into the cold-transporting-medium or heat-transporting-medium circuit. As the cold- and heat-transporting medium, the same liquid transmission medium is used.
