Description

  

      Verbund-Kompressions-Kältemaschine.       Die Erfindung     betrifft    eine Verbund  Kompressions-Kältemaschine und hat die  Vermeidung des Übelstandes zum Zweck,  dass der bei der Entspannung vom Konden  sator- auf den     Verdampferdr        uck    in Dampf  form übergehende Teil des Kältemediums,  trotzdem derselbe im Verdampfer keine Kälte  zu erzeugen vermag, mit durch den Ver  dampfer hindurchgetrieben und     rückkompri-          iniert    werden muss.

   Die Erfindung besteht  darin, dass Mittel vorgesehen sind, mit Hilfe  weicher der im Drosselorgan der Maschine  in     Dampfform    übergehende Teil des Kälte  mediums, anstatt wie bisher in den Ver  dampfer, in den Kompressor unter Umgehung  von dessen.     Niederdruckstufe    geleitet wird.  Die Mittel können aus einem dem Ver  dampfer vorgeschalteten     Dampfabscheidebe-          hälter,    mit an den Kompressor angeschlosse  nem Dampfraum, sowie aus einem den Flüs  sigkeitsaustritt aus dem Behälter derart  regelnden Organ bestehen, dass die Austritts  öffnung, zwecks Absperrung des Dampfraumes  vom Verdampfer stets mit     flüssigem    Kälte  medium überflutet ist.

   Das Regelorgan kann    dabei aus einem mit einem Schwimmer ver  bundenen Ventil bestehen.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes -ist auf der Zeichnung darge  stellt.  



       a    ist der Niederdruck-, b der Hochdruck  zylinder,     r,    der Kondensator,     d    das Drossel  organ und e der Verdampfer einer Verbund  Kompressions-Kältemaschine, in welcher das  Kältemedium in Richtung der eingezeichneten  Pfeile zirkuliert.

   Zwischen dem Drosselorgan  und dem Verdampfer ist ein     Dampfabscheide-          behälter    f angeordnet, dessen     Dampfraum     durch die Leitung     g    mit der Saugseite des  Hochdruckzylinders verbunden ist und dessen  in den Verdampfer mündende Öffnung durch  ein mit einem Schwimmer i     verbundenes     Ventil k so beeinflusst wird, dass die Öffnung  stets mit einer -den Dampfraum vom Ver  dampfer absperrenden Flüssigkeitsschicht über  flutet wird.

   Dadurch wird bewirkt, dass sich  das vom Kondensator gelieferte Kältemedium  zunächst nur bis auf den im Aufnehmer des  Kompressors herrschenden Zwischendruck ent  spannt, wobei der sich bildende Dampf, ohne      in den Verdampfer zu     gelangen,    von selbst  in den Hochdruckzylinder überströmt, während  der     noch    flüssige Teil unter weiterer Ent  spannung in den Verdampfer abfliesst. Bei  der weiteren Entspannung auf den     Ver-          dampferdruck    bildet sich so wenig Dampf,  dass dessen schädliche     Wirkung    vernachlässigt  werden kann.

   Da es zwecklos und mit Ver  lusten verbunden wäre, wenn man den auf       Zwischendruclz    entspannten Dampf weiter  entspannen wollte, um ihn darauf im Nieder  druckzylinder wieder auf den     Zwischendruck     zu     komprimieren,    so wird mit der Maschine  nach der vorliegenden Erfindung gegenüber  den     bekannten    Maschinen, bei     welchen    dieser  Dampf bis auf     Verdampferdruck        entspannt     wird, eine erhebliche Verbesserung des Wir  kungsgrades erreicht.



      Compression refrigeration machine. The invention relates to a composite compression refrigeration machine and has the purpose of avoiding the inconvenience that the part of the refrigeration medium which passes into vapor form when the pressure is released from the condenser to the evaporator pressure is not able to generate any cold in the evaporator the evaporator must be driven through and recompressed.

   The invention consists in that means are provided with the help of which part of the refrigeration medium passing in the throttle element of the machine in the form of vapor, instead of in the evaporator as before, in the compressor bypassing it. Low pressure stage is passed. The means can consist of a vapor separator container upstream of the evaporator, with a vapor space connected to the compressor, as well as an organ that regulates the liquid outlet from the container in such a way that the outlet opening is always liquid with cold in order to shut off the vapor space from the evaporator medium is flooded.

   The control element can consist of a valve connected to a float.



  An embodiment of the subject of the invention -ist on the drawing provides Darge.



       a is the low pressure cylinder, b the high pressure cylinder, r the condenser, d the throttle organ and e the evaporator of a composite compression refrigeration machine in which the refrigerant circulates in the direction of the arrows.

   Between the throttle element and the evaporator there is a vapor separation container f, the vapor space of which is connected to the suction side of the high-pressure cylinder via the line g and the opening of which opens into the evaporator is influenced by a valve k connected to a float i in such a way that the opening is always flooded with a liquid layer blocking the vapor space from the Ver evaporator.

   This has the effect that the cooling medium supplied by the condenser initially only expands up to the intermediate pressure prevailing in the compressor's transducer, whereby the vapor that forms, without reaching the evaporator, overflows into the high-pressure cylinder by itself, while the still liquid part flows into the evaporator with further relaxation. With the further expansion to the evaporator pressure, so little vapor is formed that its harmful effect can be neglected.

   Since it would be pointless and associated with losses if one wanted to further relax the steam relaxed on Zwischenendruclz in order to compress it again to the intermediate pressure in the low pressure cylinder, the machine according to the present invention is compared to the known machines in which this vapor is relaxed up to the evaporator pressure, a significant improvement in efficiency is achieved.
