Abstract: A method for estimating and/or controlling a temperature of foodstuff stored in a refrigerated cavity of a refrigeration system is disclosed. A time constant for the temperature of the foodstuff is established, said time constant being determined based on a time interval between a relatively large change of opening degree of an expansion valve and until variance of the opening degree of the expansion valve decreases to a relatively low variance. The time constant is applied to a low pass filter, said low pass filter providing a relation between the temperature of the foodstuff and the air temperature, and the low pass filter is applied to the monitored air temperature, thereby obtaining an estimate for the temperature of the foodstuff stored in the refrigerated cavity.
