Description

Absolut luftdicht abgeschlossene Kühlräume resp. Geräte, für Industrie und Haushalt wer­ den mittels einer Vakuumpumpe luftleer gepumt, bis ein Unterdruck von ca. 2 bar erreicht ist. Je größer der Druckunterschied zwischen der Außen- und Innenathmosphäre ist, um so dichter und fester schließt die Tür, die nicht verriegelt werden muß.
Im Türgriff befindet sich der Schalter, zum Ein- und Ausschalten der Vakuumpumpe und der Knopf, zum Öffnen eines Ventiles, das die Luft in den Kühl­ schrank einströmen läßt, wenn derselbe geöffnet werden soll.
Durch die Erzeugung eines Vakuums, in Kühlanlagen, wird die Luftfeuchtigkeit reduziert, bzw. ganz aufgehoben. In einem Vakuumkühlgerät können verderbliche Lebensmittel sehr viel länger aufbewahrt werden, als in Kühlgeräten mit der nor­ malen Luftfeuchtigkeit, die in den Geräten erheblich zunehmen kann, entsprechend den darin gelagerten Waren.
Der Kondenswasser-Abfluß, der in jedem Kühlgerät vorhanden sein muß, entfällt, weil sich in Vakuum-Kühlanlagen kein Kondenswasser bildet.

Claims (1)

  1. Der Patentanspruch bezieht sich auf die Einrichtung von Kühlräumen- und Geräten bei Verwendung eines Vakuums, um Kühlgut darin länger frischhalten zu können.
