  Verfahren zum Beschicken von Kältemaschinen, die mit einer Mischung von Schwefel- dioxyd und Kohlendioxyd arbeiten. 



   Die Erfindung betrifft e'n Verfahren zum Beschicken von   Kältemaschinen,   die mit einem, aus   Schwefeldioxyd und Kohlendioxyd bestehenden Kältemittel arbe@ten. Während   bei Anwendung von Kohlendioxyd allein e'n hoher Druck erforderlich ist, da e'n solcher von 75   Atm. notwend'g   ist, um das Kohlendioxyd zu verflüssigen, besitzt Schwefeldioxyd den Nachteil, die Metallteile der Anlage durch Oxydation anzugreifen. 
 EMI1.1 
 sie lange Zeit in gutem Zustande erhalten bleiben, und in der Anlage nur einen geringen Druck aufrecht zu erhalten. 
 EMI1.2 
 die ganze Anlage hindurchgeschickt wird. Dadurch wird auch alle Feuchtigkeit aus der Anlage entfernt, die auf diese Weise in reinem Zustand erhalten wird.

   Die Metallteile werden auch besser gereinigt, als dies der Fall wäre, wenn die oben genannte Mischung gleich eingefüllt würde. Die Kohlensäure bespült zunächst sämtliche Metallteile und der in der Anlage infolge des   verhältnismäss'g   hohen Gewichtes verbleibende Rest dieses Gases dient dann weiter dazu, die Oxydationswirkung des Sehwefeldioxydes zu verringern. Die Anlage wird mit Kohlendioxyd unter   einem Druck von ungefähr 22   Atm. geladen, damit dieses Gas auch wirklich in alle Teile gelangt und so   eine gründliche Reinigung   erzielt wird. worauf das Kohlendioxyd abgelassen und die Ladung und Entleerung mehrmals wiederholt wird. Dabei wird die Leitung gleichzeitig gründlich getrocknet. Schwefeldioxyd wird erst vor Betriebsbeginn   eingeführt.   



   Die Anlage kann auch nach dem Spülen mit Kohlendioxyd bei atmosphärischem Druck gefüllt bleiben, worauf das Schwefeldioxyd unter Druck eingeführt wird. Dadurch wird die   Möglichkeit   des Rostens noch weiterhin vermindert.

  Process for charging refrigeration machines that work with a mixture of sulfur dioxide and carbon dioxide.



   The invention relates to a method for charging refrigerating machines that work with a refrigerant consisting of sulfur dioxide and carbon dioxide. Whereas when using carbon dioxide alone a high pressure is required, since a pressure of 75 atm. is necessary to liquefy the carbon dioxide, sulfur dioxide has the disadvantage of attacking the metal parts of the system by oxidation.
 EMI1.1
 they remain in good condition for a long time and only maintain a low pressure in the system.
 EMI1.2
 the whole system is sent through. This also removes all moisture from the system, which is thus kept in a pure state.

   The metal parts are also cleaned better than would be the case if the above mixture were poured in straight away. The carbonic acid first flushes all metal parts and the remainder of this gas remaining in the system due to the relatively high weight then serves to reduce the oxidizing effect of the sulfur dioxide. The plant runs on carbon dioxide at a pressure of approximately 22 atm. loaded so that this gas really gets into all parts and thus a thorough cleaning is achieved. whereupon the carbon dioxide is released and the loading and unloading are repeated several times. The line is thoroughly dried at the same time. Sulfur dioxide is only introduced before the start of operations.



   The system can remain filled at atmospheric pressure even after flushing with carbon dioxide, whereupon the sulfur dioxide is introduced under pressure. This further reduces the possibility of rusting.
