57	Abstract	AB	Ein zweistufiger Absorptionskühler zum Erreichen, dass ein Wärmeaustauscherabschnitt zum Herunterkühlen eines Absorbers einer Niedrigtemperaturseite durch einen Verdampfer einer Hochtemperaturseite klein gemacht wird sowie dass eine Zone zur Nutzung des Wärmeausstoßes beim Senken der Temperatur einer Antriebswärmequelle vergrößert wird, wobei ein Abschnitt zum Herunterkühlen des Absorbers der Niedrigtemperaturseite durch den Verdampfer der Hochtemperaturseite so aufgebaut ist, dass ein Kältemittel der Hochtemperaturseite innerhalb von Rohren vertikaler Heizrohre verdampft wird, während ein Kältemitteldampf der Niedrigtemperaturseite außerhalb der Rohre absorbiert wird, und wobei das Kältemittel in die Rohre zugeführt wird, indem man das Kältemittel aus einer Kältemittelverteilungskammer, die auf einem oberen Abschnitt der Heizrohre vorgesehen ist, obere Enden der Heizrohre überfließen lässt, wodurch ein Rieselfilm innerhalb der Rohre gebildet wird. Damit ist es möglich, im Vergleich zu dem Fall, in dem das Kältemittel von unteren Abschnitten der Heizrohre zugeführt wird, einen Druckverlust innen in den Rohren zu reduzieren, und dadurch funktioniert eine Wärmeübertragungsfläche zum Herunterkühlen einer Lösung außerhalb der Rohre effektiv, während die Verdampfungstemperatur gesenkt und abgeflacht wird.
