Description
Absorptionskältemaschine. Eine Absorptionskältemaschine besteht im ,vesentlichen aus einem Gefäß, dem Kochapparat, in dem eine Lösung von beispielsweise Ammoniak in Wasser erhitzt wird. Der entstandene Ammonialzdampf wird zu einem Kondensator, wo er verflüssigt wird, und dann im flüssigen Zustande zu einer Entspannungsvorrichtung, beispielsweise einem Reduzierventil, und schließlich zu einem anderen Gefäß, dem Refrigerator, geleitet. In diesem verdampft das flüssige Ammoniak unter Aufnahme der Wärme der Umgebung. Der entstandene kalte Ammoniakdampf wird nun in ein drittes Gefäß, das Absorptionsgefäß, hineingeleitet, in dem er wieder in Wasser gelöst wird, wobei das Absorptionsgefaß entsprechend gekühlt wird. Nach einem einige Zeit dauernden Betrieb erhält man also im Kochapparat eine arme Lösung unter einem höheren Druck und im Absorptionsgefäß eine reichere Lösung unter einem niedrigeren Druck. Damit der Vorgang ununterbrochen bleibt, ist eine Anordnung zurCberführung der ausgetriebenen Dämpfe, die in dem Wasser des Absorptionsgefäßes gelöst sind, in clas Kochgefäß erforderlich.Absorption chiller. An absorption chiller consists of the , essentially from a vessel, the cooking apparatus, in which a solution of, for example Ammonia is heated in water. The resulting ammonia vapor becomes a condenser, where it is liquefied, and then in the liquid state to an expansion device, for example a reducing valve, and finally to another vessel, the Refrigerator, headed. In this it evaporates liquid ammonia while absorbing the warmth of the environment. The resulting cold ammonia vapor is now led into a third vessel, the absorption vessel, in which he again is dissolved in water, the absorption vessel being cooled accordingly. To So if you run it for some time, you get a poor solution in the cooking apparatus under a higher pressure and in the absorption vessel a richer solution under one lower pressure. So that the process remains uninterrupted, there is an arrangement for transferring the expelled vapors dissolved in the water in the absorption vessel, in clas cooking vessel required.
Gemäß der Erfindung erfolgt die Cberf Uhrung dieser gelösten Dämpfe in das Kochgefäß Jurch Zuhilfenahme des osmotischen Druckes. Wenn sich an beiden Seiten einer sogenannten semipermeablen Membran eine Lösung eines Stoffes in einem Lösungsmittel befindet und die Konzentration an der einen Seite größer ist als an der anderen, so wandert, wie bekannt, ein Teil des gelösten Stoffes durch die Membran, bis beispielsweise die Konzentration an beiden Seiten gleich ist oder ein Gleichgewicht in anderer Weise erreicht wird. Diejenige Kraft, welche diese Wirkung herbeiführt, ist der osmotische Druck, der sehr erhebliche Werte erreichen kann.According to the invention, these dissolved vapors are transferred into the cooking vessel by using osmotic pressure. If at both A so-called semipermeable membrane is a solution of a substance in one Solvent is located and the concentration is greater on one side than on the other, as is known, a part of the solute migrates through the membrane, until, for example, the concentration on both sides is the same or an equilibrium is achieved in a different way. The force that brings about this effect is the osmotic pressure, which can reach very considerable values.
Eine Ausführungsform einer Absorptionskältemaschine gemäß der Erfindung ist auf der Zeichnung schematisch veranschaulicht.An embodiment of an absorption refrigerator according to the invention is illustrated schematically on the drawing.
Das Kochgefäß i wird durch die Erhitzungsvorrichtung .2 erwärmt. Der entstandene Dampf wird in dem Kondensator 3 kondensiert und strömt dann durch das Reduzierorgan 4 in den Refrigerator 5. Der entstandene kalte Dampf wird in das Absorptionsgefäß 6 hineingeführt, das mit einer Kühlvorrichtung 7 versehen ist. Zwischen dem Absorptionsgefäß 7 und dem Kochgefäß i ist in geeigneter Weise eine semipermeable Membran 8 angeordnet. Die Meinbran, welche beispielsweise aus einem entsprechend geformten Körper aus unglasiertern Porzellan, da-. z. B. mit Paraffin behandelt ist, bestehen kann, läßt, nachdem die Konzentration im Absorptionsgefäß 6 einen gewissen Wert im Verhältnis zu der Konzentration im Kochgefäß i überschreitet, das Ammoniak durch, bis eine von dem Druck und der Temperatur an beiden Seiten der Membran bestimmte Gleichgewichtslage erreicht wird. Nachdem diese Gleichgewichtslage erreicht worden ist, kann also der Vorgang unbehindert fortgehen.The cooking vessel i is heated by the heating device .2. The resulting steam is condensed in the condenser 3 and then flows through the reducing element 4 into the refrigerator 5. The resulting cold steam is fed into the absorption vessel 6 , which is provided with a cooling device 7 . A semipermeable membrane 8 is arranged in a suitable manner between the absorption vessel 7 and the cooking vessel i. The Meinbran, which, for example, consists of a correspondingly shaped body made of unglazed porcelain. z. B. treated with paraffin, can exist, after the concentration in the absorption vessel 6 exceeds a certain value in relation to the concentration in the cooking vessel i, the ammonia through until an equilibrium position determined by the pressure and the temperature on both sides of the membrane is achieved. After this equilibrium position has been reached, the process can continue unhindered.
Die Membran kann auch aus einer geeigneten Flüssigkeit bestehen, die das Ammonial, nicht oder wenigsten-, in geringerem Maße als Wasser löst, welche Flüssigkeit zwischen zwei Membrauen aus geeignetem Material, z. B. Kautschtik-, eingelassen ist.The membrane can also consist of a suitable liquid which the ammonia, not or at least, to a lesser extent than water dissolves which Liquid between two membrane lobes made of a suitable material, e.g. B. Kautschtik-, is let in.
Wenn eine ungesättigte Lösung von beispielsweise Ammoniak in Wasser in einem Gefäß mit für Ammoniak durchlässigen, für Wasser aber undurchlässigen Wänden aufbewahrt wird und dieses Gefäß in einer Ammoniakatmosphäre aufbewahrt wird, durchdringt Ammoniak die Wände, bis ein von Temperatur und Druck abhängiges Gleichgewicht erreicht wird. Es ist also nicht notwendig, die Ammoniakdämpfe zuerst in Wasser zu lösen, bevor sie dem halb durchlässigen Organ zugeführt werden. Die Ammoniakdämpfe können vielmehr in einem passend ausgebildeten Teil des Kochers gelöst werden, nachdem sie das halbdurchlässige Organ durchdrungen haben. Es wird hierdurch möglich, wenigstens zum Teil die Lösungswärme nützlich zu machen und hierdurch die Wärmebilanz zu verbessern.If an unsaturated solution of, for example, ammonia in water is kept in a vessel with walls that are permeable to ammonia but impermeable to water, and this vessel is kept in an ammonia atmosphere, ammonia will permeate the walls until an equilibrium, dependent on temperature and pressure, is reached. It is therefore not necessary to first dissolve the ammonia vapors in water before they are supplied to the semi-permeable organ. Rather, the ammonia vapors can be dissolved in a suitably designed part of the digester after they have penetrated the semipermeable organ. This makes it possible to make the heat of solution useful at least in part and thereby to improve the heat balance.
