Abstract

L'invention concerne un système de réfrigération comprenant une enceinte pour machine à glaçons dans un compartiment pour denrées fraîches. Ce système comprend une voie de réfrigération et une voie pour machine à glaçons. La voie pour machine à glaçons comprend un détendeur électronique destiné à réguler la quantité de réfrigérant entrant dans l'évaporateur pour machine à glaçons et un régulateur de pression de l'évaporateur. La régulation du système de réfrigération comprend les étapes consistant à détecter une première température de réfrigérant à la sortie de l'évaporateur de la machine à glaçons et à surveiller une première commande du détendeur électrique jusqu'à ce que la température atteigne une température cible. Le procédé de commande peut, en outre, consister à comparer la courbe de température vers au moins un réglage minimum, cible ou maximum pour réguler la commande. Par conséquent, une seconde commande du détendeur électronique peut être régulée de manière répétée par évaluation de la première température du réfrigérant et de la courbe.
