Abstract
In the present study, energy and exergy analyses of a solar powered absorption refrigeration system are corried out by terms of the first and second laws of thermodynamics. NH3-H2O fluid couple is used in the system. The analyses are performed with the help of Engineering Equation Solver software program. Exergy destruction rate in each component, coefficient of performance and exergy efficiency of overall system are calculeted. In addition, effect of generator, evaporator and condenser temperatures are investigated on the system performance. Maximum COP and exergy efficiency are determined to be 0.50 and 36%, respectively. It is observed that generator, evaporator and condenser temperatures significantly affect the system performance.
Keywords - Energy, exergy, absorption refrigeration, NH3-H2O
