• Evaporator 7 and aftercooler 5 are designed as a plate heat exchanger and the absorber 8 as Rieselfilmabsorber, wherein absorber and aftercooler are arranged side by side and below the evaporator 7.
• The desorber consists of a regenerative and a externally heated part, which are located in a horizontal pressure shell. The regeneratively heated part is located in the upper part of the pressure shell and consists of two chambers which are formed by the guide plate 17 and the bottom plate 16. The externally heated part is located in the lower part of the pressure shell and consists of 3 chambers which are formed by the baffles 14 and 15 and the bottom plate 16. The countercurrent flow of solvent and refrigerant vapor is realized by means of weirs and windows.
• The brine outlet temperature is controlled by the supply of the poor solution in the absorber 8. The level in the desorber 1 is determined by the speed of the ...
Description
Das Verfahren ist vorteilhaft anwendbar für die Kälteerzeugung unter 0°C vorzugsweise im Bereich kleinerer Leistungen oberhalb 10 kW für in Serie herzustellende Absorptionskälteanlagen mit vertretbaren Anschaffungskosten.The Method is advantageously applicable for the cooling below 0 ° C preferably in the range of smaller powers above 10 kW for series-produced absorption refrigeration systems with reasonable acquisition costs.
Aufgabe ist es, das bekannte Absorptionskälteverfahren für kleine und mittlere Leistungen zu modifizieren und den Anwendungsbereich für Leistungen bis unter 50 kW so zu optimieren, dass eine Konkurrenzfähigkeit zum Kompressionskälteverfahen hergestellt wird.task It is the well-known absorption cooling method for small and medium performances and the scope of application for services to under 50 kW so to optimize that competitiveness for Kompressionskälteverfahen will be produced.
Die
Aufgabe wird gelöst
durch die Wahl Trockenverdampfer
Die Entwicklung betrifft ein Verfahren und eine Einrichtung der Kältebereitstellung unter 0°C nach dem Sorptionsprinzip. Als Arbeitspaar sind Mischungen der reinen Flüssigkeiten Ammoniak und Wasser vorgesehen. Für den Leistungsbereich bis 50 kW sind Heizparameter oberhalb 100°C erforderlich.The Development relates to a method and apparatus of refrigeration provision below 0 ° C the sorption principle. As a working couple are mixtures of pure liquids Ammonia and water provided. For the power range up 50 kW, heating parameters above 100 ° C are required.
Absorptionskälteanlagen

Druckniveau auf, das durch die Kondensation des Kältemittels
bestimmt wird, und im kalten Teil ein niedriges Druckniveau, das
durch die Verdampfungstemperatur des reinen Kältemittels geprägt ist.
Die Beschreibungen beziehen sich deshalb sowohl auf den Hochdruck-
