Allgemeine Beschreibung:General description:

Bei der beschriebenen Erfindung handelt es sich um ein besonders kostengünstige Form der Temperaturregelung die durch einen externen Sensor erfolgt..The invention described is a particularly cost-effective form of temperature control which is carried out by an external sensor.

Technische Beschreibung:Technical description:

Bei der Erfindung handelt es sich um einen außen am Kühlgerät angebrachten Temperatursensor, der die Umgebungstemperatur misst. Das Messergebnis wird einer Steuerungseinheit zugeführt, die den Energieverbrauch des Kühlgerätes vorhersagt. Diese Vorhersage kann erfolgen, da der Energieverbrauch bei Kühlgeräten vorwiegend durch die Stillstandsverluste bestimmt sind. Diese sind abhängig von der Umgebungstemperatur. Durch das Vorhersageergebnis wird die Energieabnahme für das Kälteaggregat voreingestellt. Abhängig vom verwendeten Kälteaggregat kann somit das Schaltprofil so gewählt werden, dass dieses nur bei einer bestimmten Leistung mit maximalem Wirkungsgrad betrieben wird. Dazu kann es sinnvoll sein sowohl die Leistung wie auch das Verhältnis von Laufzeit bzw. Pausenzeit zu variieren.The invention is a temperature sensor attached to the outside of the cooling device that measures the ambient temperature. The measurement result is fed to a control unit that predicts the energy consumption of the cooling device. This prediction can be made because the energy consumption of cooling devices is mainly determined by the downtime losses. These are dependent on the ambient temperature. The prediction result is used to preset the energy consumption for the cooling unit. Depending on the cooling unit used, the switching profile can be selected so that it only operates at a certain power with maximum efficiency. To do this, it can be useful to vary both the power and the ratio of running time to pause time.

Stand der Technik - Vorteile der Erfindung:State of the art - Advantages of the invention:

Bislang werden Kühlaggregate in Kühlgeräten zumeist durch Zweipunktregler gesteuert, die ihren Messwert von im Kühlschrank befindlichen Sensoren beziehen. Da zur Anbringung dieser Sensoren die Dämmschicht des Kühlgerätes durchbrochen werden muss, ist ein Anbringen dieser Senoren teuer. Zudem muss der Sensor durch Verkapseln vor der im Kühlgerät befindlichen Feuchtigkeit geschützt werden. Durch den innen liegenden Sensor ist eine Vorhersage des Energieverbrauchs nicht möglich.Up to now, cooling units in refrigerators have mostly been controlled by two-point controllers that get their measured values from sensors located in the refrigerator. Since the insulation layer of the refrigerator has to be penetrated to attach these sensors, installing these sensors is expensive. In addition, the sensor has to be protected from the moisture in the refrigerator by encapsulating it. Because the sensor is located inside, it is not possible to predict energy consumption.

Anwendung der Erfindung:Application of the invention:

Die Erfindung kann bei allen Kühlgeräten mit Temperaturregelung angewandt werden. Im besonderen sind Vorteile bei solchen Kühlgeräten gegeben, bei denen durch Variation der Aggregatsleistung bessere Wirkungsgrade erzielt werden können.The invention can be applied to all cooling devices with temperature control. It is particularly advantageous for cooling devices where better efficiencies can be achieved by varying the unit output.
