In this study, the Second-Law analysis is performed on solar assisted absorption cooling system A computational model based on entropy generation has been developed to investigate the entropy generation of each component and the total entropy generation of all the system components as well as the system coefficient of performance. The results show that the COP and irreversibilities are inversely proportional to the condenser and absorber and increase with an increase in the generator and evaporator temperature. Furthermore, the solar collector component plays the biggest part in the total entropy generation rate of the solar absorption cooling system followed by the generator, the absorber and the evaporator. Thus, these components should be developed to provide less entropy generation.
