Abstract: In a method for controlling the operation of a compressor, the compressor is switched off by a controller in order to prevent thermal damage if an estimated temperature value calculated by the controller exceeds an upper threshold value. The controller calculates a cooling function as a state variable utilizing the estimated temperature value, the cooling function representing the chronological course of the cooling of the compressor. The controller determines the cooling function based on at least one first and one second estimated temperature value which are associated with points of the compressor that are at spatial distances to each other. The calculation of the cooling function is based on a temperature difference between the first and second estimated temperature values.
