Abstract: The invention relates to a method for controlling a compressor of a refrigeration system, said compressor having a motor, wherein the temperature of the cooling point is controlled by means of switch-on and switch-off operation of the motor if the temperature in the compressor exceeds an upper temperature threshold and the temperature of the cooling point is controlled by means of continuously switched-on operation of the motor as soon as the motor has cooled down to a lower temperature threshold, wherein the control system converts a manipulated variable corresponding to the cooling demand of the cooling point into a switching signal for a valve, which switching signal causes clocked opening and closing of the valve, or a frequency converter controls the refrigerant flow through the compressor by controlling the voltage and the frequency of the motor, in that the frequency converter converts a manipulated variable corresponding to the cooling demand of a cooling point into a voltage and a frequency for the motor.
