Abstract:
1. A method for controlling a cooling device for vehicles, wherein said cooling device includes a refrigerant compressor, a condenser arranged downstream of the refrigerant compressor in a flow direction of the refrigerant, a first evaporator arranged downstream of the condenser for cooling the air to be supplied to a passenger compartment, a second evaporator arranged parallel to the first evaporator for cooling an electric accumulator, and a control unit configured to control the refrigerant compressor as a function of at least one of a cooling demand for the passenger compartment and a cooling demand for the electric accumulator on the basis of the higher cooling demand, comprising the acts of: determining which of a cooling demand of the electric accumulator and a cooling demand of the passenger compartment is greater; if the cooling demand of the electric accumulator is not greater than the cooling demand of the passenger compartment, controlling a closed loop control of the refrigerant compressor with the control unit based on the cooling demand of the passenger compartment; if the cooling demand of the electric accumulator is greater than the cooling demand of the passenger compartment, determining whether the cooling demand of the passenger compartment is zero; if the cooling demand of the passenger compartment is zero, controlling the refrigerant compressor with the control unit to a predefined refrigerant compressor rotational speed; and if the cooling demand of the passenger compartment is not zero, controlling a the refrigerant compressor with the control unit to the predefined rotational speed.
