KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Vorrichtung zur Erzeugung von Kälte, bei der als Kälteträger Stoffe verwendet werden, wie z. B. Äthylchlorid, Methyläthyläther, Formaldehyd. Sie besteht darin, daß diese Kälteträger mittels eines Kreisel Verdichters verdichtet werden, welcher an sich ein- oder mehrstufig sein kann und so ausgebildet ist, daß er für den gasförmigen Teil des Kälteträgers aus einemThe invention relates to a device for generating cold, in which as a refrigerant Substances are used, such as B. ethyl chloride, methyl ethyl ether, formaldehyde. she consists in that these coolants are compressed by means of a centrifugal compressor, which can be one or more stages per se and is designed so that it is suitable for the gaseous part of the coolant from a
ίο großen und für den flüssigen Teil aus einem kleinen, zu dem ersteren parallel geschalteten Verdichter besteht, durch die jeder Teil des Kälteträgers auf den gewünschten Druck gebracht wird. Um den flüssigen Teil des Kälteträgers, der in der Regel sehr viel kleiner ist als der gasförmige Teil, auf den gewünschten Enddruck zu bringen, bedarf es wegen des viel höheren spezifischen Gewichtes nur eines kleinen Kreisels. Dieser wird dem für das gasförmige Kühlmittel erforderlichen großen Verdichter parallel geschaltet. Das hierfür erforderliche Kreiselrad wird zweckmäßigerweise in dem Gehäuse des Hauptverdichters untergebracht. Durch diese Unterteilung werden die nicht unbeträchtlichen Reibungsverluste vermieden, die notgedrungen entstehen mußten, wenn der flüssige Teil zusammen mit dem gasförmigen durch die für die Verdichtung des letzteren erforderlichen Kreiselräder geleitet wurde.ίο large and for the liquid part from one small compressor in parallel with the former, through which each part of the Coolant is brought to the desired pressure. To the liquid part of the secondary refrigerant, which is usually a lot is smaller than the gaseous part, it needs to be brought to the desired final pressure because of the much higher specific weight of only one small top. This will be the for the gaseous refrigerant required large compressor connected in parallel. That The impeller required for this is expediently in the housing of the main compressor housed. This subdivision avoids the not inconsiderable frictional losses that are inevitable had to arise when the liquid part together with the gaseous part through the for the compaction of the latter required gyro wheels was passed.
Die Zeichnung zeigt ein Ausführungsbeispiel an Hand einer mit Äthylchlorid arbeitenden Kältemaschine. Für die Verdichtung des gasförmigen Teiles des Kälteträgers sind zwei hintereinander geschaltete Kreiselräder α und b in das Gehäuse c eingebaut, dem der Kälteträger durch den Stutzen d zufließt. Der Saugraum ist durch eine Wand e in zwei Teile geschieden, so daß der gasförmige Teil des Kälteträgers nach rechts abgesaugt wird, der flüssige Teil desselben dem kleinen Kreiselrad f zufließt und von diesem allein auf den erwünschten Druck gebracht und durch den Stutzen g weitergeleitet wird. Der verdichtete Teil des gasförmigen Äthylchlorids verläßt das Gehäuse c durch den Stutzen h. Der Kreiselverdichter wird angetrieben durch den Elektromotor i. The drawing shows an exemplary embodiment using a refrigeration machine operating with ethyl chloride. For the compression of the gaseous part of the refrigerant, two centrifugal wheels α and b connected one behind the other are built into the housing c, to which the refrigerant flows through the nozzle d . The suction chamber is divided into two parts by a wall e , so that the gaseous part of the refrigerant is sucked off to the right, the liquid part of it flows to the small impeller f and is brought to the desired pressure by this alone and passed on through the nozzle g. The compressed part of the gaseous ethyl chloride leaves the housing c through the nozzle h. The centrifugal compressor is driven by the electric motor i.
