Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Abtauen des Reifansatzes an Verdampfern von Kühlmö­ beln, bei dem das Abtauen automatisch in Abtauintervallen erfolgt, deren Beginn und deren Dauer jeweils im voraus festgelegt werden. The invention relates to a method and a device for defrosting the ripening on evaporators from refrigerated cabinets with defrosting automatically at defrosting intervals takes place, the beginning and duration of each in advance be determined.

Um das Abtauen des Reifansatzes sicher und energie­ sparend zu gestalten, wird vorgeschlagen, von den vorgege­ benen Abtauintervallen nur so viele freizugeben, wie dem Abtaubedarf entsprechen. Dabei ist es von Vorteil, wenn die Anzahl und Aufeinanderfolge der freigegebenen Abtauinter­ valle in Abhängigkeit von der Schmelzzeit und diese in Abhängigkeit von dem Verlauf der Temperatur des Ver­ dampfers bestimmt werden. To defrost the frost base safely and energy To save, it is proposed by the preceding only release as many defrost intervals as that Defrost requirement. It is advantageous if the Number and sequence of the approved defrosters valle depending on the melting time and this in Depending on the course of the temperature of the ver be determined.
