Abstract
Description
Die vorliegende Erfindung betrifft einen Kühlschrank mit mehreren Kühlfächern und ein Verfahren zum Abtauen eines solchen Kühlschranks.The The present invention relates to a refrigerator with a plurality of refrigerators and a method for defrosting such a refrigerator.
Allgemeiner Stand der Technikgeneral State of the art
Ein typischer Kühlschrank hat zwei separate Fächer, die auf verschiedenen Temperaturen gehalten werden, wenigstens einen Kompressor zum Zuführen von Kältemittel und einen oder mehrere Verdampfer, über die die warme Luft aus den Fächern mittels eines Gebläses zirkuliert. Das Gebläse zieht die wärmere Luft aus den Fächern und zirkuliert sie über die Verdampferoberflächen und bläst kältere Luft in die Fächer. Das Zirkulieren warmer Luft über den Verdampfern führt zum Aufbau einer Reifschicht auf dem Verdampfer und senkt die Effizienz des Kühlschranks. Darum wird der Reif periodisch während eines Abtauzyklus' abgeschmolzen.One typical fridge has two separate compartments, which are kept at different temperatures, at least one Compressor for feeding of refrigerant and one or more evaporators, over which the warm air comes from the subjects by means of a blower circulated. The fan pulls the warmer Air from the subjects and circulate it over the evaporator surfaces and blows colder air into the subjects. Circulating warm air over the Evaporates leads To build a frost layer on the evaporator and lowers the efficiency of the refrigerator. Therefore, the hoarfrost periodically during a defrost cycle 'melted.
Während des Abtauzyklus' hört der Kompressor auf zu arbeiten, und es wird eine Wärmequelle aktiviert. Eine häufig benutzte Wärmequelle ist eine Widerstandsheizvorrichtung. Die Verwendung von Widerstandsheizvorrichtungen erhöht den Energieverbrauch. Des Weiteren ist die Effizienz des Abtauens mit Widerstandsheizvorrichtungen im Allgemeinen sehr gering, ungefähr 30%, das heißt, der größte Teil der Energie wird für das Beheizen des Schrankes verbraucht anstatt zum Abschmelzen des Reifs.During the Defrost cycle 'hears the compressor to work, and a heat source is activated. A frequently used one heat source is a resistance heater. The use of resistance heaters elevated the energy consumption. Furthermore, the efficiency of defrosting with resistance heaters generally very low, about 30%, this means, the biggest part the energy is going for the heating of the cabinet consumes instead of melting the hoop.
Im US-Patent Nr. 5,406,805 werden zwei separate Verdampfer für jedes der Fächer verwendet. Das Abtauen des Frischhaltefach-Verdampfers erreicht man durch Zirkulieren der Luft aus dem Frischhaltefach durch den Verdampfer mittels eines Gebläses, wenn der Kompressor abgeschaltet ist. Der Warmluft-Abtauprozess ist nur dann effektiv, wenn der Kompressor abgeschaltet ist. Weil der Kompressor während der Abtau-Periode abgeschaltet ist, kann die Temperatur im Frischhaltefach und insbesondere im Gefrierfach aufgrund der längeren Abtaudauer im Vergleich zum Abtauen mit Widerstandsheizvorrichtungen über die zulässigen Grenzwerte hinaus ansteigen. Um also ein effizientes Abtauen zu gewährleisten, wird auch eine Widerstandsheizvorrichtung verwendet, was die Vorteile des Luft-Abtauens mindert und auch die Kosten erhöht.in the U.S. Patent No. 5,406,805 will be two separate evaporators for each the subjects used. The defrosting of the fresh compartment evaporator achieved by circulating the air from the fresh compartment through the Evaporator by means of a blower, when the compressor is off. The warm air defrost process is effective only when the compressor is off. Because the compressor during the defrost period is turned off, the temperature in the fresh food compartment and especially in the freezer due to the longer defrost time in comparison to defrost with resistance heaters beyond the allowable limits. Thus, to ensure efficient defrosting, a resistance heater also becomes used, which reduces the benefits of air defrosting and also the Costs increased.
