Description

Kleinabsorptionskältemaschine. Zweck der Erfindung ist, eine Absorptionskältemaschine von beschränkten Ausmaßen für Kleinbetriebe, wie Konditoreien, Metzgereien u. dgl., zu schaffen. Die Erfindung besteht im wesentlichen darin, daß ein Vorkondensator, der Kondensator, der Temperaturwechsler uns der Absorber in ring- oder schraubenförmigen Rohrgängen oder in gleichbedeutender Anordnung um den ganzen Kocher und nicht nur, wie für Vor- und Hauptkondensator bekannt, um den Kocherdom gelegt werden. Hierdurch wird eine noch weitergehende Veränderung der Bauhöhe erzielt.Small absorption chiller. The purpose of the invention is an absorption chiller of limited dimensions for small businesses such as pastry shops, butchers and the like, to accomplish. The invention consists essentially in the fact that a precondenser, the condenser, the temperature changer and the absorber in ring or helical form Pipe runs or in an equivalent arrangement around the entire cooker and not only, as known for the preliminary and main condenser, to be placed around the digester dome. Through this an even further change in the overall height is achieved.

Ein Ausführungsbeispiel der Erfindung ist in cler Zeichnung dargestellt. In dieser bedeuten : 1 den Kocher, 2 den Vorkondensator, 3 den Kondensator, .1 den Verdampfer, 5 den Absorber, V den Temperaturwechsler, 7 die Ammoniakpumpe. 8 die Saugeleitung, 9 die Einspritzleitung, to den Regulierhahn, 11 Manometer, 12 Thermometer, 13 Rückschlagventil, 14. Sicherheitsventil, 15 Ammoniakabsperrhahn, 16 Kühlwasserhahn, 17 Heizkörper, 18 Ammoniakfüllstutzen, 19 Flüssigkeitsanzeiger.An embodiment of the invention is shown in the drawing. In this: 1 the digester, 2 the precondenser, 3 the condenser, 1 den Evaporator, 5 the absorber, V the temperature changer, 7 the ammonia pump. 8 the Suction line, 9 the injection line, to the regulating valve, 11 manometer, 12 thermometer, 13 check valve, 14. safety valve, 15 ammonia shut-off valve, 16 cooling water valve, 17 radiators, 18 ammonia filler necks, 19 liquid indicators.

Der besseren Übersichtlichkeit wegen sind die Rohrleitungen, soweit sie verschiedene Medien führen, gestrichelt, strichpunktiert crler ausgezogen. Die Kühlwasserleitungen sind gestrichelt, die Lösungsleitungen strichpunktiert und die Ammoniakleitungen ausgezogen. Die Kühlwasserschlangen liegen konachsial innerhalb der Rohre des Absorbers, des Kondensators und des Vorkondensators und ebenso ein Teil der Saugeleitung der Pumpe konzentrisch in dem Rohr des Temperaturwechslers.For the sake of clarity, the pipelines are so far they lead different media, dashed, dash-dotted crler undressed. the Cooling water lines are dashed, the solution lines are dash-dotted and the Ammonia lines pulled out. The cooling water coils lie conaxially within the tubes of the absorber, the condenser and the pre-condenser and also a Part of the suction line of the pump concentric in the tube of the temperature changer.

Die Wirkungsweise der Anlage ist folgende: Das mit Ammoniak gesättigte Wasser, Salmiakgeist, wird durch das Rohr a in den Kocher gedrückt. Der Kocher wird in seinem unteren Teil geheizt (Heizkörper 17), wobei durch die Erwärmung ,die Ammoniakdämpfe aus dem Salmiakgeist ausgetrieben werden, so daß sich am Boden des Kochers eine an Ammoniak arme Lösung ansammelt. Die Ammoniakdämpfe, mit etwas Wasserdämpfen vermischt, steigen im Kocher auf. und gelangen durch den Absperrhahn 15 in den halbbogenförmig um den Kocher geführten Vorkondensator 2. Durch diesen Vorkondensator 2 wird Kühlwasser geleitet (Leitung b), so daß die den Ammoniakdämpfen noch beigemischten Wasserdämpfe in dem Vorkondensator kondensieren und durch eine Rohrleitung c in den Kocher 1 zurückfallen. Die Ammoniakdämpfe fließen aus .dem Vorkondensator 2 durch das Rohr d in den Kondensator 3, wo sie unter dem Einfluß des Drukkes, unter dem sie stehen, und der Kühlschlange e kondensieren. Aus dem Kondensator gelangt das flüssige Ammoniak durch den Regulierhahn to und die Leitung 9 in den Verdämpfer ¢, verdampft hier und fließt nun in Dampfform durch die Leitung 8 und ein Rückschlagventil 13 zum Absorber 5, wo es durch das im Absorber befindliche Wasser bzw. die an Ammoniak, arme Lösung absorbiert wird. Aus dem Absorber 5 saugt die Ammoniakpumpe 7 die nunmehr an Ammoniak reiche Lösung, den Salmiakgeist, durch die Leitung f an und drückt sie durch das Rohr g in -den Temperaturwechsler 6. Von hier aus gelangt sie dann durch das Rohr a wieder in den Kocher. Andererseits wird die am Boden des Kochers angesammelte arme Lösung durch das Rohr k und durch eine in der Rohrschlange des Temperaturwechslers geführte zweite Rohrschlange und durch das Rohr h in den Absorber und von diesem, wie erwähnt, durch das Rohr f in die Ammoniakpumpe geleitet. Hierbei folgt in ari sich bekannter Weise ein Temperaturausgleich zwischen der aus dem Kocher gesaugten armen Lösung und der in den Kocher gedrückten reichen Lösung.The system works as follows: The ammonia-saturated water, known as ammonia, is pressed through the pipe a into the cooker. The lower part of the cooker is heated (heating element 17), the ammonia vapors being driven out of the ammonia spirit by the heating, so that a solution poor in ammonia collects at the bottom of the cooker. The ammonia vapors, mixed with some water vapors, rise in the stove. and pass through the shut-off valve 15 into the pre-condenser 2, which is led in a semi-arc around the cooker . The ammonia vapors flow from the precondenser 2 through the pipe d into the condenser 3, where they condense under the influence of the pressure they are under and the cooling coil e. From the condenser, the liquid ammonia passes through the regulating valve to and the line 9 into the evaporator [, evaporates here and now flows in vapor form through the line 8 and a check valve 13 to the absorber 5, where it passes through the water in the absorber or the in ammonia, poor solution is absorbed. From the absorber 5, the ammonia pump 7 sucks the ammonia-rich solution, the ammonia, through the line f and pushes it through the pipe g into the temperature changer 6. From here it then passes through the pipe a back into the cooker . On the other hand, the poor solution accumulated at the bottom of the digester is passed through the pipe k and through a second pipe coil guided in the pipe coil of the temperature changer and through the pipe h into the absorber and from this, as mentioned, through the pipe f into the ammonia pump. Here, in a manner known per se, there is a temperature equalization between the poor solution sucked out of the digester and the rich solution pushed into the digester.

" Es sei noch darauf hingewiesen, daß der Vorkondensator a in solcher Höhenlage zum Kocher angeordnet ist, daß das von den Ammoniakdämpfen mitgerissene, im Vorkon:densator kondensierte Wasser von selbst, d. h. ohne besondere Vorrichtungen, durch die Leitung c zum Kocher zurückfließt."It should be noted that the precondenser a in such At an altitude of the stove that the ammonia vapors entrained water condensed in the precondenser by itself, d. H. without special devices, flows back through line c to the digester.
