...Nicolás Velázquez; Daniel Sauceda; Margarito Quintero-Núñez; Roberto Best This paper presents the design criteria, methodology. and results of the basic and detailed engineering for a descending film ammonia absorber using air cooled finned tubes, which is part of an advanced absorption cooling...

... by a photocatalytic step. At the Florida Solar Energy Center (FSEC), a novel hybrid photo-thermochemical sulfur-ammonia (S–A) cycle has been developed. The main reaction (unique to FSEC’s S–A cycle) is the light-induced photocatalytic production of hydrogen and ammonium sulfate from an aqueous ammonium sulfite...

...Shaoguang Lu; D. Yogi Goswami A novel combined power/refrigeration thermodynamic cycle is optimized for thermal performance in this paper. The cycle uses ammonia-water binary mixture as a working fluid and can be driven by various heat sources, such as solar, geothermal, and low temperature waste...

...Afif Akel Hasan; D. Y. Goswami Exergy thermodynamics is employed to analyze a binary ammonia water mixture thermodynamic cycle that produces both power and refrigeration. The analysis includes exergy destruction for each component in the cycle as well as the first law and exergy efficiencies...

...T. F. Qu; W. Wang; R. Z. Wang Mass recovery can play an important role to better the performance of adsorption refrigeration cycles. Cooling capacity can be significantly increased with mass recovery process. The coefficient of performance (COP) of the activated carbon/ammonia adsorption...

...H. Kreetz; K. Lovegrove; A. Luzzi Solar energy storage using a closed loop thermochemical system based on the reversible dissociation of ammonia, has been investigated at the Australian National University for over two decades. Theoretical and system studies have indicated that large scale systems...
