Thermal design of a tray-type distillation column of an ammonia/water absorption refrigeration cycle
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The goal of this paper is to present an analysis of a segmented weir sieve-tray distillation column for a 17.58 kW (5 TR) ammonia/water absorption refrigeration cycle. Balances of mass and energy were performed based on ...
Heat and mass transfer in falling films technology applied to the generator and the rectifier of an ammonia-water absorption refrigeration cycleTransfert de chaleur et de masse dans la technologie des films tombants appliquée au générateur et au rectificateur d'un cycle frigorifique à absorption d'ammoniac-eau
(2022-03-01)
Powering ammonia-water absorption refrigeration cycles with solar energy demands an operating temperature above 170 ∘C for the proper generator operation when conventional flooded generator technologies are used. However, ...
Diagrammes entropiques pour des mélanges ammoniac-eau: applications aux systèmes frigorifiques à absorption
(2017-10-01)
The objective of this work is to calculate the entropy of ammonia–water mixture as a function of temperature, pressure, concentration, and other thermodynamic properties associated to absorption process, to support energy ...
Attempt of integration of a small commercial ammonia-water absorption refrigerator with a solar concentrator: experience and resultsTentative d'intégration d'un réfrigérateur commercial à absorption à ammoniac / eau de petite taille et d'un capteur solaire: expérience acquise et résultats
(Elsevier Science, 2011-12)
The integration of a small commercial ammonia-water absorption refrigerator with a solar concentrator as heat source was analyzed theoretically and experimentally. Operation parameters of the fridge were determined by ...
