ABSTRACT:
A method for controlling a temperature in a refrigeration system using a quality decay value expressing an expected decay rate in quality of the products being refrigerated, and which depends on the temperature of air present in the refrigeration system. The quality decay value is obtained using a mathematical model reflecting one or more physical and/or biological processes in the products. Prevents or reduces the quality degradation of the products in terms of shelf life, appearance or tastiness. Furthermore, a method for controlling the temperature in such a way that effects of scheduled events, such as temperature increase during defrosts, can be compensated prior to the event.
