Abstract: In order to identify the amounts and locations of irreversibility within the components of the cycle, exergy analysis is employed. A two-phase constant area ejector flow model was used. As the ejector component efficiencies increase, coefficient of performance and exergy efficiency increase. As a result, when the efficiencies of motive nozzle and diffuser are 100%, the efficiency of ejector suction nozzle increases from 20% to 100%, whereas the improvement ratio in cooling coefficient of performance and that of exergy efficiency increase at approximately 4.3 times. It was also found that as ejector component efficiencies fall, optimum ejector area ratio increases.
