Thermodynamic Analysis of Single Effect Vapor Absorption Refrigeration Cycle
Md. Meraj, Dr. M. Emran Khan, Rashid Imam
Abstract: Present day utilization of low grade energy like solar energy, geothermal energy, waste heat from industries etc. are a challenge. Vapor absorption refrigeration (VAR) cycle is a best alternative to vapor compression refrigeration (VCR) cycle, despite of having low coefficient of performance compared to VCR because it is heat operated. In this paper the energetic and exergetic analysis of single effect vapor absorption refrigeration cycle using the LiBr2-H2O solution as working fluid is done. This analysis is done for the evaporator temperature of 5, 7.5, 10 and 12.5 0C and the main condenser temperature of 30 and 35 0C. The absorber temperature is assumed to be equal to condenser temperature. The calculated results indicate that the value of maximum value of coefficient of performance and maximum exergetic efficiency comes out to be 0.8055 to 0.8849 and 0.3062 to 0.5116 respectively. Exergy destruction is highest in absorber on comparison with other component.
