Beschreibung
Zusammenfassung:	A method for controlling the defrost of an evaporator in a refrigeration appliance provided with a temperature sensor used for detecting temperature inside a cell of the appliance comprises measuring the evaporator temperature, applying an algorithm which, on the basis of the temperature inside the cell and the temperature of the evaporator, simulates the thermodynamic behavior of the cell, and detecting a change in any of the parameters of the above algorithm which is indicative of a need to defrost.
