AN EXERGY ANALYSIS OF SOLAR-ASSISTED EJECTOR COOLING SYSTEM FOR DIFFERENT AREA RATIOS AT THEIR MAXIMUM COEFICIENTS OF PERFORMANCE VALUES

ABSTRACT
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.
