Abstract

Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Kühl- und/oder Gefriergerätes mit zwei oder mehr als zwei Kompartimenten (10,20,30), die jeweils über wenigstens eine durch ein Verschlusselement (14,24,34) verschließbare Öffnung verfügen, durch die die Kompartimente mit Kaltluft beaufschlagbar sind, wobei wenigstens ein Temperaturfühler (12,22,32) zur mittelbaren oder unmittelbaren Erfassung des jeweiligen Temperaturistwertes vorgesehen ist, wobei für mehrere oder alle dieser Kompartimente ein Temperaturwert (Schließwert) definiert ist, dass das Kompartiment mit der geringsten Differenz zwischen Temperaturistwert und Schließwert (Temperaturdifferenz) ermittelt wird und dass das Verschlusselement (14,24,34) dieses Kompartimentes geschlossen wird, bis diese Temperaturdifferenz gleich oder größer ist als die Temperaturdifferenz eines Kompartimentes mit einer größeren, vorzugsweise mit der nächstgrößeren Temperaturdifferenz. The present invention relates to a method of operating a refrigerator and / or freezer with two or more than two compartments (10,20,30), each of which has at least one by a closure element (14,24,34) lockable opening through are acted upon the compartments with cold air, at least one temperature sensor (12,22,32) is provided for direct or indirect detection of the respective actual temperature, wherein a temperature value for several or all of these compartments (closing value) is defined such that the compartment with the smallest difference between actual temperature and closing value (temperature difference) is determined and that the closure element (14,24,34) of the compartment is closed up to this temperature difference is equal to or greater than the temperature difference a compartment with a larger, preferably with the next larger temperature difference.
