Analysis of internal heat recovery capability in air-cooled indirect fired GAX-based absorption chiller in part-load operation

“…In AirCooled ammonia-water absorber refrigeration systems, the ammonia vapour purification process becomes more important as the ambient temperature increases. With high-efficiency stripping sections, the design of the column of distillation can be simplified by eliminating the rectifying section [ 9 ]. In addition to the ammonia vapour purification system, other subcomponents are added to the basic single-effect ammonia water absorption cycle to improve its performance.…”

Experimental analysis of ammonia–water rectification in absorption systems with the 10mm metal Pall ring packing

“…The current methods of reducing the water content in the vapour leaving the generator are by means of a liquidvapour counterflow contacting device in a distillation column, by partial condensation in a rectifier or by combining both methods. Theoretical analyses of these processes have been carried out by several researchers (Kang et al, 1996;Anand and Erickson, 1999;Fernandez-Seara et al, 2002, 2003aSieres and Ferná ndez-Seara, 2006), though experimental studies are quite scarce (Mortal and Roriz, 2002;Sieres and Ferná ndezSeara, 2007a,b).…”
