AB - In this paper, the exergy analysis of solar-assisted ejector cooling system  (SAECS) was investigated with different ejector area ratios such as Ar=6.56,  Ar=7.17 and Ar=7.86. The analysis was performed on maximum coefficients of  performance (COP) values of each ejector area ratio based on the  experimental results. The SAECS was the combination of two subsystems  including solar collector and ejector cooling. Exergy analysis was applied  independently for each subsystem. The largest exergy destruction in cooling  subsystem took place in the ejector followed by the generator, condenser,  and evaporator, respectively. Exergy destruction proportions were 42.9%,  44.7% and 45.2% in the ejector, 10.9%, 9.1% and 10.1% in generator, 7.6%,  7.7% and 8.7% in condenser, 5.9%, 5.6% and 5.8% in evaporator of total  cooling subsystem for different ejector area ratios. Although proportions  were almost the same for each device, exergy destruction amounts increased  with the increase of ejector area ratio.
