A device and method is provided for automatically defrosting a refrigeration system. The present invention includes a microprocessor (102) which initiates a defrost cycle during a time of day which is most efficient for the refrigerator (50) and the utility company. Moreover, the defrost cycle is initiated during a time of day which has the least impact on food stored within the refrigerator (50). The microprocessor (102) is programmed and enabled so as to analyze the power consumption of the refrigerator during a 24-hour period, and from this analysis, the microprocessor (102) is able to determine the time of day and period(s) of time which will be most efficient for the initiation of a defrost cycle.

L'invention concerne un dispositif et un procédé pour dégivrer automatiquement un système de réfrigération. L'invention comprend un microprocesseur (102) qui démarre un cycle de dégivrage à un moment de la journée qui est le plus efficace pour le réfrigérateur (50) et la société d'électricité. De plus, le cycle de dégivrage est démarré à un moment de la journée qui a le moins de conséquence pour la nourriture stockée dans le réfrigérateur (50). Le microprocesseur (102) est programmé et validé de manière à analyser la consommation de courant du réfrigérateur sur une période de 24 heures, et à partir de cette analyse, le microprocesseur (102) peut déterminer le moment de la journée et la(les) périodes les plus efficaces pour démarrer un cycle de dégivrage.
