Vorrichtungen zum Kühlen mittels flüssiger Luft, bei denen die Dämpfe der flüssigen Luft in Rohrschlangen durch den zu kühlenden Raum hindurchgeschickt werden, sind bekannt. Bei diesen Kühlvorrichtungen wird jedoch die Verdampfung der flüssigen Luft lediglich durch die der nächsten Umgebung entnommene Wärme veranlaßt. Da nun jede gewöhnliche atmosphärische Luft Feuchtigkeit besitzt, die sich in Form von Reif an den kalten mit der Außenluft in Berührung stehenden Flächen niederschlägt, so entsteht sehr bald eine hinderliche Isolation durch den Reif. Im Gegensatz hierzu und um diesenDevices for cooling by means of liquid air, in which the vapors of the liquid Air are sent in coils through the room to be cooled known. In these cooling devices, however, the evaporation of the liquid air caused only by the heat taken from the immediate vicinity. Since now each Ordinary atmospheric air possesses moisture, which takes the form of frost precipitates the cold surfaces in contact with the outside air, this is how very soon an obstructive isolation through the hoop. In contrast to and around this
Übelstand zu beseitigen, soll gemäß vorliegender Erfindung die genügende bzw. erhöhte Wärmezufuhr dadurch bewerkstelligt werden, daß die aus flüssiger Luft entstandene verdampfte Luft, nachdem sie Kühlung verbreitet und sich wieder erwärmt hat, nochmals in die flüssige Luft zurückgeführt wird. Hierdurch wird erreicht, daß eine genau regelbare Verdampfung möglich ist. Der Umstand, daß die in die flüssige Luft zurückgeführte gasförmige Luft keine Fremdkörper, insbesondere keinen Wasserdampf, besitzt, bringt es mit sich, daß ein Vereisen bzw. Eingefrieren der Rohre ausgeschlossen und die Verdampfung der flüssigen Luft infolge von Reifansatz nicht beeinträchtigt bzw. verlangsamt wird.According to the present invention, the deficiency should be sufficient or increased Heat supply can be achieved in that the resulting from liquid air evaporated Air, after it has spread cooling and warmed up again, is again returned to the liquid air. This means that precisely controllable evaporation is possible. The fact that it is returned to the liquid air gaseous air has no foreign bodies, in particular no water vapor, it means that freezing or Freezing of the pipes and the evaporation of liquid air as a result is not impaired or slowed down by the setting of frost.
Auf der Zeichnung ist ein Kühlschrank, der diesen Gedanken verwirklicht, im Querschnitt dargestellt, h ist der Behälter für flüssige Luft, f ein Regelventil, / das Einfüllrohr für die flüssige Luft, d und e sind Kühlkammern, x, o, a, b und η sind Rohrleitungen. In the drawing, a refrigerator that realizes this idea is shown in cross section, h is the container for liquid air, f a control valve, / the filling pipe for the liquid air, d and e are cooling chambers, x, o, a, b and η are pipelines.
Nach Abnahme der Füllschraube i füllt man flüssige Lnft durch das Rohr I in den Behälter h, wodurch infolge der Kupferschlange s Wärme in die Flüssigkeit geführt wird. Diese verdampft und die kalten Dämpfe ziehen durch Röhr χ nach dem Flächenkühler d, woselbst sie von oben nach unten durch die einzelnen Wandungen herabstreichen und die Umgebung kühlen. Die Luft kann dann in erwärmtem Zustande durch das Regelventil f mit Hilfe des Griffes g direkt vom Rohr b nach dem Rohr 0 geleitet werden, um dann bei ρ auch in den zweiten Flächenkühler c einzutreten, damit sie beim Durchstreichen desselben ihre Kälte möglichst vollständig an die Umgebung abgeben kann.After removing the filling screw i , liquid air is poured into the container h through the pipe I , whereby heat is conducted into the liquid as a result of the copper coil s. This evaporates and the cold vapors pass through the tube χ to the surface cooler d, where they brush down through the individual walls from top to bottom and cool the environment. The heated air can then be passed through the control valve f with the help of the handle g directly from the pipe b to the pipe 0 in order to then also enter the second surface cooler c at ρ , so that when it is passed through it, its coldness is as completely as possible to the Environment.
Wünscht man nun in dem Kühlschrank die Temperatur zu regeln bzw. eine tiefere Temperatur herzustellen, so stellt man den Hahn f so ein, _ daß das Rohr b mit dem Rohr α durch einen vollen oder gedrosselten Durchgang verbunden ist. Ein Teil oder die ganze Menge der warmen Gase wird dann nochmals in den Flüssigkeitsbehälter h geleitet, wo sie sich abkühlen und gleichzeitig mehr flüssige Luft im Behälter h verdampfen.If one now wishes to regulate the temperature in the refrigerator or to produce a lower temperature, then the cock f is set so that the tube b is connected to the tube α by a full or throttled passage. Some or all of the warm gases are then passed back into the liquid container h , where they cool down and at the same time more liquid air evaporates in the container h.
