Abstract

A cooling device and to a method for controlling a cooling device for vehicles is provided, the cooling device including a refrigerant compressor, a condenser downstream of the refrigerant compressor in the flow direction of the refrigerant, a first evaporator downstream of the condenser for cooling air to be supplied to the passenger compartment, a second evaporator arranged parallel to the first evaporator for cooling an electric accumulator, and a control unit which is configured to control the refrigerant compressor as a function of the cooling demands for the passenger compartment and/or the electric accumulator on the basis of the higher cooling demand requirement. The cooling device may further include electric valves between the condenser and the first and second evaporators to control a cooling capacity of the first and/or second evaporator to meet the cooling demands of the passenger compartment and/or the electric accumulator.
