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. From time to time, the low-boiling ones have to come from refrigeration and air conditioning systems Refrigerants are withdrawn, for example by To carry out repair work. The refrigerant is under Relieved pressure in the collecting container. One remains small amount of refrigerant in the system due to pressure relief and Rinsing the line is removed. This goes Refrigerant is lost and the environment is also polluted. To do that The ability to collect refrigerant without loss Collection container (1) cooled down so much by a cryogenic coolant that that the refrigerant with the formation of a negative pressure condensed in the collecting container.
