Abstract

Die Erfindung betrifft ein Kühl- und/oder Gefriergerät mit einem Kühlkreislauf, der wenigstens einen Verdampfer und wenigstens einen Kompressor umfaßt, mit einem im Bereich des Verdampfers angeordneten Verdampfer-Temperaturfühler sowie mit einer Steuereinheit, die mit dem Verdampfer-Temperaturfühler sowie mit dem Kompressor in Verbindung steht und die derart ausgeführt ist, dass sie den Kompressor einschaltet, wenn die mittels des Verdampfer-Temperaturfühlers gemessene Temperatur einen oberen Grenzwert (Einschaltwert) übersteigt, mit einem Umgebungstemperaturfühler der die Umgebungstemperatur des Kühl- und/oder Gefriergerätes erfaßt, wobei eine Einheit zur Änderung des Einschaltwertes vorgesehen ist, die mit dem Umgebungstemperaturfühler in Verbindung steht und die derart ausgeführt ist, dass bei höheren Umgebungstemperaturen ein geringerer Einschaltwert eingestellt oder ausgewählt wird als bei demgegenüber geringeren Umgebungstemperaturen.The invention relates to a refrigerator and / or freezer with a cooling circuit comprising at least one evaporator and at least one compressor, with an evaporator temperature sensor arranged in the region of the evaporator and with a control unit connected to the evaporator temperature sensor and the compressor in Connected and which is designed such that it turns on the compressor when the temperature measured by the evaporator temperature sensor exceeds an upper limit (switch-on), with an ambient temperature sensor which detects the ambient temperature of the refrigerator and / or freezer, wherein a unit for Is provided change of the switch-on, which is in communication with the ambient temperature sensor and which is designed such that at higher ambient temperatures, a lower switch-on value is set or selected as compared to lower ambient temperatures.
