摘要：

Conventional and enhanced exergy analyses of a waste heat powered ejector refrigeration system using exhausted gas from rotary kiln were carried out. Isentropic (R290, R141b and R142b), wet (R134a and R152a) and dry fluids (R600a) were considered in the cycle in terms of avoidable-unavoidable parts of the exergy destruction to decide improvement potentials of the overall system. The results indicate a significant issue; the importance of component can change regarding refrigerant. The ejector comes into view as an important component to improve the overall cycle performance for R134a while the generator shows the best improvement potential for R600a.
