  • Method for operating a coolant circuit for a vehicle air-conditioning system
    Patent number: 11104204
    Abstract: A method for operating a cooling circuit. It is provided that a) the actuation signal ST of the coolant compressor is provided so as to increase over time from a minimum value (STmin) in order to generate a start-up phase of the coolant compressor, b) a control signal maximum value (STmax) and a control signal threshold (STSW) are provided, where STSW<STmax, c) the actuation signal (ST) is limited to the control signal maximum value (STmax) if the actuation signal (ST) reaches the control signal threshold (STSW) and the measured high and/or low-pressure value (PHD, PND) satisfies a condition.
