Abstract

Aus Kälte- und Klimaanlagen müssen gelegentlich die tiefsiedenden Kältemittel abgezogen werden, beispielsweise um Reparaturarbeiten durchzuführen. Das Kältemittel wird hierzu unter Druck in Auffangbehälter abgelassen. Dabei verbleibt eine kleine Kältemittelmenge in der Anlage die durch Druckentlastung und Spülen der Leitung entfernt wird. Hierdurch geht Kältemittel verloren, zudem wird die Umwelt belastet. Um das Kältemittel verlustfrei auffangen zu können, wird der Auffangbehälter (1) durch ein cryogenes Kühlmittel so stark abgekühlt, daß das Kältemittel unter Ausbildung eines Unterdruckes im Auffangbehälter kondensiert.
