A method of controlling a refrigeration system comprising a refrigerant, an evaporator, a compressor, a condenser, and an electronically adjustable throttle device, comprising the steps of: performing superheating control of the refrigerant at the evaporator outlet via a controller by controlling the opening degree of the electronically adjustable throttle device, activation of a special function control via a special function controller when the refrigeration system is in specific operating states, characterised in that the special function control of the special function controller intervenes in the superheating control of the refrigerant at the evaporator outlet via the controller, wherein an adaptation unit serves for controlling the adaptation of the controller, parametrisation of the controller for superheating the refrigerant at the evaporator outlet is optimally matched to the current operating point of the refrigerant circuit controlled system, a characteristic curve for adapting the controller dynamics is stored in the adaptation unit, influencing the controller parameters in a first determination unit in dependence of the set value of refrigerant superheating at the evaporator outlet, optimal matching of the controller to the current operating point of the refrigerant circuit is performed by matching the parametrisation of the controller for superheating of the refrigerant at the evaporator outlet, enabling the controller dynamics adaptation special function is controlled via a detection unit, and terminating the special function control when the refrigeration system returns to normal operation in which superheating control of the refrigerant at the evaporator outlet is performed via the controller. performing superheating control of the refrigerant at the evaporator outlet via a controller by controlling the opening degree of the electronically adjustable throttle device, activation of a special function control via a special function controller when the refrigeration system is in specific operating states, characterised in that the special function control of the special function controller intervenes in the superheating control of the refrigerant at the evaporator outlet via the controller, wherein an adaptation unit serves for controlling the adaptation of the controller, parametrisation of the controller for superheating the refrigerant at the evaporator outlet is optimally matched to the current operating point of the refrigerant circuit controlled system, a characteristic curve for adapting the controller dynamics is stored in the adaptation unit, influencing the controller parameters in a first determination unit in dependence of the set value of refrigerant superheating at the evaporator outlet, optimal matching of the controller to the current operating point of the refrigerant circuit is performed by matching the parametrisation of the controller for superheating of the refrigerant at the evaporator outlet, enabling the controller dynamics adaptation special function is controlled via a detection unit, and terminating the special function control when the refrigeration system returns to normal operation in which superheating control of the refrigerant at the evaporator outlet is performed via the controller.
