Title
(EN) A MODEL PREDICTION CONTROLLED REFRIGERATION SYSTEM
(FR) SYSTEME DE REFRIGERATION COMMANDE PAR PREDICTION DE MODELE
Abstract
(EN)
The invention provides a refrigeration system with a compressing unit, and a method of controlling a refrigeration system. To facilitate a better control, the capacity of the compressing unit is controlled based on a predicted future cooling demand rather than an actually determined cooling demand. The invention further provides a system wherein a cost value for changing the cooling capacity of the system is taken into consideration.
(FR)
L'invention concerne un système de réfrigération équipé d'une unité de compression et un procédé de commande dudit système de réfrigération. Afin d'améliorer la fonction de commande du système, la capacité de l'unité de compression est réglée en fonction d'une demande de refroidissement future prévue plutôt que d'une demande de refroidissement réellement déterminée. L'invention concerne également un système dans lequel le coût du changement de la capacité de refroidissement du système est pris en compte.
