The research of the effect of the environment's temperature against the cooling cycle with Li-Br+H2O fluid and single staged absorbtion in the basic of the exergy analysis

THE RESEARCH OF THE EFFECT OF THE ENVIRONMENT?S TEMPERATUREAGAINST THE COOLING CYCLE WITH LiBr + H2O FLUID AND SINGLESTAGED ABSORBTION IN THE BASIC OF THE EXERGY ANALYSISSami Murat GÜRSÜRERMechanical Engineering, M.S. ThesisAbsorption refrigeration systems are more economical than vapour compression systems,since in the previous one heat energy is used rather than electrical. In lithium bromide+watersystem it is not possible to cool below 0ºC; however, in these systems hot water or wastesteam can be used, and it has been recently applied for cooling purposes. In this study, exergyanalysis which is made of a lithium bromide + water refrigeration system at differentenvironment temperature values and the cooling capacity, performance coefficiency andcooling water requirement were determined.The most significant conclusion out of this study; for constant COP, the second yield law ofthermodynamics is positive rated with the environmental temperature values.Keywords: Absorption, refrigeration, exergy analysis, available energy, efficiency of secondlaw, availability, lithium bromide + water.JURY :1.
