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.
