Abstract

Die Erfindung betrifft eine einstufige Ammoniak-Wasser Absorptionskältemaschine im Batch-Verfahren bestehend aus Generator (1) mit Druckabsenker (29) und Lösungskonzentrationsoptimierung (3), Absorber (14), Kondensator (25), Verdampfer (24) wobei der Generator (1) zusammen mit einem rückgekühlten Eingangsgefäß (3) und dem Druckabsenker eine Bau- und Druckeinheit bilden, worin der Druckabsenker (29) zu Beginn jedes Arbeitszyklus den Generatordruck unter den Absorberdruck absenkt, sodass von dort über ein Rückschlagventil (69) Lösung in das rückgekühlte Generatoreingangsgefäß (3) fließt, dieses füllt und dass von dort die Lösung der Schwerkraft folgend allmählich in eine heiße Zone (1) fließt, welche insbesondere aus einer vom Absorber (18) her gewärmten Vorwärmzone (11) und einer extern beheizten heißen Zone (12) besteht, wo Ammoniakdampf entsteht, der mit einer Siphonleitung (8) von unten durch die noch im Generatoreingangsgefäß (3) befindliche restliche Lösung strömt und wo vom oberen Ende dieses Generatoreingangsgefäßes eine Gasleitung durch ein Rückschlagventil (27) zum Kondensator (25) führt, während die aus der heißen Zone (1) ausfließende ausgekochte Lösung durch den Druckabsenker (29) und durch ein Rückschlagventil (40) sowie eine Druckverminderungsstufe (17) zum Absorber (14) strömt.
