“…Gogoi and Konwar (2016) observed that irreversibility of system increases with evaporator, condenser and absorber temperature and concluded that total exergy destruction of LiCl-H2O is lower compared to that of LiBr-H2O VARS. There are many literatures (Gebreslassie et al 2012, Rubio-Maya et al 2012, Marcos et al 2011, Arora and Kaushik 2009 available for optimization of LiBr-H2O VARS. Samanta and Basu (2016) carried out realistic comparison between two approaches of thermodynamics and optimum generator temperature corresponding to first and second law perspectives also have been evaluated for LiBr-H2O VARS.…”

This study presents thermodynamic analysis and optimization of single effect LiCl-H2O absorption cooling system. Thermodynamic models are employed in engineering equation solver to compute the optimum performance parameters. In this study, cut off temperature to operate system has been obtained at various operating temperatures. Analysis depicts that on 3.59 % rise in evaporator temperature, the required cut-off temperature decreased by 12.51%. By realistic comparison between thermodynamic first and second law analysis, optimum generator temperature relative to energy and exergy based prospective has been evaluated. It is found that optimum generator temperature is strong function of evaporator and condenser temperature. Thus, it is feasible to find out optimum generator temperature for various combinations of evaporator and condenser temperatures. Contour plots of optimum generator temperature for several combinations of condenser and absorber temperatures have been also depicted. Keywords

“…The results show 5% decrease in product cost per exergy unit and 10% increase in COP. Optimizing a water-lithium bromide single effect absorption refrigeration system has done by Rubio-Maya [13] to minimize the annual operating cost. Consequently, by decreasing annual operating cost the rate of exergy destruction is doubled.…”

This paper proposes and investigates an improved ejector-absorption refrigeration system for providing the cooling load of an office building. Performance hourly modeling of the system is performed based on modeling the hourly required cooling load and hourly solar insolation rate on July 21 with maximum solar insolation. The results indicate that during the given day thermodynamic coefficient of performance (COP ) and th exergetic coefficient of performance (COP ) increase 150 and 300%, respectively. While, the product cost per
