  KältemittelfürKältemaschinen. 



   Es wurde bereits vorgeschlagen, als Kältemittel für Kältemaschinen Methylehlorid oder Mischungen dieses Chlorides mit Äthyl-oder Methylalkohol zu verwenden, um die Eisbildung in den Maschinen zu verhindern. Es hat sich nun gezeigt, dass bei Wahl eines bestimmten Mischungsverhältnisses von Methyl-

 alkohol (CH3 0 H). 



   Diese Mischung hat nicht wie Methylchlorid die Neigung, bei verhältnismässig niedrigen Tempe-   ratures,     wie-20 bis-24  C Krystalle   oder eine Art Schlamm zu bilden, wodurch der Durchgang durch die Öffnung des Ausdehnungsventiles erschwert wird. 



   Die angebene Mischung ist auch leicht fliiehtig. Nach der gegenwärtigen Kenntnis siedet sie bei   normalem   Druck bei   etwa -26 bi -270 C.   



   Ihre Verdampfungswärme ist grösser als die der bekannten Kältemittel. Bei ihrer Anwendung bleibt ferner das Schmiermittel in der Flüssigkeit suspendiert und wird in den Verdichter unter praktischer Beibehaltung seiner vollen   Schmierfähigkeit eingeführt.   



   Ein weiterer Vorteil besteht darin, dass sie sich nach vorgenommenen Versuchen bei 15 bis   16 0 ('   schon unter einem Druck von etwa 3 Atm. verflüssigt.

 alcohol (CH3 0 H).



   Unlike methyl chloride, this mixture does not have the tendency to form crystals or a kind of sludge at relatively low temperatures, such as -20 to -24 C, which makes passage through the opening of the expansion valve difficult.



   The specified mixture is also easily volatile. According to current knowledge, it boils at about -26 to -270 C.



   Their heat of vaporization is greater than that of the known refrigerants. Also, when used, the lubricant remains suspended in the liquid and is introduced into the compressor while practically maintaining its full lubricity.



   Another advantage is that, according to tests, it liquefies at 15 to 16 0 ('under a pressure of around 3 atm.
