Description

  

      Kältemaschine.       Gegenstand der Erfindung ist eine Kälte  maschine, welche unter sehr hohem Vakuum  arbeitet und bei der eine     Verdampfungs-          flüssigkeit    verwendet wird, die bei sehr tiefen  Temperaturen siedet.  



  Bei derartigen Anlagen können die bis  lang üblichen Schmiermittel, wie Glyzerin  und dergleichen nicht verwendet werden, da  sie weder den hohen Kältegraden standhalten,  noch unter der Einwirkung der Verdampf     ungs-          mittel        unzersetzt    bleiben. Es muss daher ein  besonderes Schmiermittel gewählt werden,  welches diese Übelstände nicht besitzt. Als  solches hat sich nach eingehenden Versuchen       Äthylenglykol    oder eine Mischung von       Äthylenglykol    mit Glyzerin bewährt, welche  Schmiermittel mit dem     Verdampfungsmittel     keine Verbindung eingehen, sich mit ihm  nicht mischen und bei der tiefen Kälte nicht  gefrieren.



      Chiller. The invention relates to a refrigeration machine which operates under a very high vacuum and in which an evaporation liquid is used that boils at very low temperatures.



  In systems of this type, the lubricants that have been customary for a long time, such as glycerine and the like, cannot be used since they neither withstand the high degrees of cold nor remain undecomposed under the action of the evaporation agents. A special lubricant must therefore be selected that does not have these drawbacks. As such, ethylene glycol or a mixture of ethylene glycol with glycerine has proven itself as such, which lubricants do not combine with the evaporation agent, do not mix with it and do not freeze in the deep cold.

Claims (1)

PATENTANSPRUCH: Kältemaschine, die mit sehr hohem Va kuum und mit bei sehr tiefen Temperaturen siedender Verdampfungsflüssigkeit arbeitet, dadurch gekennzeichnet, dass als gleichzeitiges Abdichtungs- und Schmiermittel Äthylen- glykol zur Verwendung kommt, welches sich mit dem Kältemittel nicht mischt, keine Verbindung mit ihm eingeht, von ihm nicht zersetzt wird und bei tiefen Temperaturen nicht gefriert. UNTERANSPRUCH: Kältemaschine, dadurch gekennzeichnet, dass als gleichzeitiges Abdichtungs- und Schmiermittel eine Mischung von Äthylen- glykol mit Glyzerin zur Verwendung kommt. PATENT CLAIM: Refrigeration machine that works with a very high vacuum and with evaporation liquid boiling at very low temperatures, characterized in that ethylene glycol is used as a sealant and lubricant at the same time, which does not mix with the refrigerant and does not form any connection with it , is not decomposed by it and does not freeze at low temperatures. SUBSTANTIAL CLAIM: Refrigeration machine, characterized in that a mixture of ethylene glycol with glycerine is used as a simultaneous sealant and lubricant.
