A method for controlling a compression refrigeration system comprising: - a refrigerant, - an evaporator, - a compressor, - a condenser, - a throttle valve and - a control unit a) for detecting a high pressure and a low pressure of the refrigerant in the compression refrigeration system, b) for detecting a speed of the compressor, c) for providing speed range classes of the compressor, each speed range class defining, for a speed range of the compressor, which counteracting measures from a list of possible measures are permissible for complying with the permissible working range of components of the compression refrigeration system, in particular the compressor, and d) for controlling at least one actuator of the compression refrigeration system, in particular at least the throttle valve and/or the compressor, based on the detected high pressure and the detected low pressure, in particular with the aid of a control signal assigned to the respective actuator; wherein the method includes the following steps: - determining, for the current speed of the compressor, a maximum permissible high pressure (HDmax), a minimum permissible high pressure (HDmin), a maximum permissible low pressure (NDmax) and a minimum permissible low pressure (NDmin), - determining differences between the current high pressure and the minimum and maximum permissible high pressures, as well as differences between the current low pressure and the maximum and minimum permissible low pressures, - determining the current speed range class for complying with the permissible counteracting measures, - determining, for each permissible counteracting measure, a change factor of the control signal of the actuator associated with the counteracting measure in dependence of at least one of the determined differences, - controlling the compression refrigeration system based on the determined change factors of the actuators. - a refrigerant, - an evaporator, - a compressor, - a condenser, - a throttle valve and - a control unit a) for detecting a high pressure and a low pressure of the refrigerant in the compression refrigeration system, b) for detecting a speed of the compressor, c) for providing speed range classes of the compressor, each speed range class defining, for a speed range of the compressor, which counteracting measures from a list of possible measures are permissible for complying with the permissible working range of components of the compression refrigeration system, in particular the compressor, and d) for controlling at least one actuator of the compression refrigeration system, in particular at least the throttle valve and/or the compressor, based on the detected high pressure and the detected low pressure, in particular with the aid of a control signal assigned to the respective actuator; a) for detecting a high pressure and a low pressure of the refrigerant in the compression refrigeration system, b) for detecting a speed of the compressor, c) for providing speed range classes of the compressor, each speed range class defining, for a speed range of the compressor, which counteracting measures from a list of possible measures are permissible for complying with the permissible working range of components of the compression refrigeration system, in particular the compressor, and d) for controlling at least one actuator of the compression refrigeration system, in particular at least the throttle valve and/or the compressor, based on the detected high pressure and the detected low pressure, in particular with the aid of a control signal assigned to the respective actuator; - determining, for the current speed of the compressor, a maximum permissible high pressure (HDmax), a minimum permissible high pressure (HDmin), a maximum permissible low pressure (NDmax) and a minimum permissible low pressure (NDmin), - determining differences between the current high pressure and the minimum and maximum permissible high pressures, as well as differences between the current low pressure and the maximum and minimum permissible low pressures, - determining the current speed range class for complying with the permissible counteracting measures, - determining, for each permissible counteracting measure, a change factor of the control signal of the actuator associated with the counteracting measure in dependence of at least one of the determined differences, - controlling the compression refrigeration system based on the determined change factors of the actuators.
