Abstract

Die Erfindung betrifft eine Zwei- oder Mehrstoff-Kompressions-Wärmepumpe bzw. -Kältemaschine mit Lösungskreislauf, die als Arbeitsmedium ein Gemisch aus zwei oder mehreren Stoffen, z.B. ein Ammoniak-Wassergemisch hat. Der Erfindung liegt der Gedanke zugrunde, die Leistungsziffer der betreffenden Maschine zu erhöhen. Die Lösung dieser Aufgabe besteht darin, daß die technisch nutzbare Wärme der reichen Lösung ganz oder teilweise zur weiteren Entgasung der armen Lösung benutzt wird, wobei die weiter entgaste Komponente oder Komponenten des Gemisches vorzugsweise von der reichen Lösung resorbiert wird und zwar so, daß die dadurch freiwerdende Absorptionswärme für die weitere Entgasung der armen Lösung benötigt wird. Hiermit kann die angestrebte maximale Resorbertemperatur bei einem niedrigeren Druck als ohne diese Maßnahme erreicht und die Kälteleistung der Maschine erhöht werden, da dadurch die weitere Abkühlung der reichen Lösung ermöglicht wird.The invention relates to a dual or multi-fuel compression heat pump or refrigeration machine with a solution circuit, which has a mixture of two or more substances, e.g. an ammonia-water mixture, as the working medium. The invention is based on the idea of increasing the performance factor of the machine in question. The solution to this problem is that the technically usable heat of the rich solution is wholly or partially used for further degassing of the poor solution, the further degassed component or components of the mixture preferably being resorbed by the rich solution in such a way that the result heat of absorption released is required for further degassing of the poor solution. In this way, the desired maximum absorber temperature can be achieved at a lower pressure than without this measure and the cooling capacity of the machine can be increased, since this enables the rich solution to be cooled further.

Die Erfindung betrifft eine Zwei- oder Mehrstoff-Kompressions-Wärmepumpe bzw. -Kältemaschine mit Lösungskreislauf und Entgasung der armen Lösung durch Wärme der reichen Lösung, die als Arbeitsmedium ein Gemisch aus zwei oder mehreren Stoffen, insbesondere aus Ammoniak und Wasser, hat, bei der die aus dem Resorber austretende reiche Lösung ihre technisch nutzbare Wärme in einem Temperaturwechsler an die aus dem Entgaser dem Resorber zugeführte arme Lösung im möglichen Umfang abgibt.The invention relates to a dual or multi-fuel compression heat pump or -cooling machine with solution cycle and degassing of the poor solution by heat of the rich solution, which is used as the working medium has a mixture of two or more substances, in particular ammonia and water, in which the from The rich solution exiting the resorber transfers its technically usable heat to the in a temperature changer releases poor solution supplied to the resorber from the degasser to the extent possible.

Eine solche Maschine ist bekannt (R. Plank, Handbuch der Kältetechnik, Band 7, Sorptionskältemaschinen, S. 93-95, Springer-Verlag, 1959). Die Einschaltung eines Temperaturwechslers zwischen den Resorber und den Entgaser und das Vorsehen einer Lösungsvorführung im Entgaser verfolgen den Zweck, die Leistungsziffer der Maschine zu erhöhen. Such a machine is known (R. Plank, Handbuch der Kältetechnik, Volume 7, Sorption Chillers, pp. 93-95, Springer-Verlag, 1959). The activation a temperature changer between the resorber and the degasser and the provision of a solution demonstration The purpose of the degasser is to increase the performance of the machine.

Der Erfindung liegt die Aufgabe zugrunde, die Leistungs::iffer der eingangs genannten Maschine noch weiter zu erhöhen.The invention is based on the object of the achievement :: iffer of the machine mentioned above to increase further.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß die technisch nutzbare Restwärme der aus dem Temperaturwechs'er austretenden reichen Lösung ganz oder teilweise zur weiteren Entgasung der dem Temperaturwechsler zugeführten armen Lösung benutzt wird.This object is achieved according to the invention in that the technically usable residual heat of the rich solution emerging from the temperature change wholly or partially used for further degassing of the poor solution fed to the temperature changer will.

Die Erfindung beruht auf dem Gedanken, daß durch die Nutzung der Restwärme der reichen Lösung nach dem Temperaturwechsler zur weiteren Entgasung der armen Lösung die angestrebte maximale Resorbertemperatur bei einem niedrigeren Druck als ohne diese Maßnahme erreicht werden kann. Außerdem wird mit der erfindungsgemäßen Maßnahme die Kälteleistung der Maschine erhöht, da dadurch die weitere Abkühlung der reichen Lösung und damit die Wärmeaufnahme bei niedrigerer Temperatur im Entgaser ermöglicht wird.The invention is based on the idea that by using the residual heat of the rich solution the temperature changer for further degassing of the poor solution the desired maximum absorber temperature at a lower pressure than can be achieved without this measure. In addition, with the measure according to the invention increases the refrigeration capacity of the machine, as this results in further cooling the rich solution and thus the heat absorption is made possible at a lower temperature in the degasser.

Die Leistungsziffererhöhung ist dann noch weiter steigerbar, wenn jeder der bei der weiteren EntgasungThe increase in the coefficient of performance can then be further increased if each of the persons involved in further degassing
