摘要：

This study examines both conventional and advanced exergy analyses of a modified ejector-enhanced auto-cascade refrigeration (MEACR) cycle. Conventional exergy analysis shows that the proposed model significantly improves exergy efficiency compared to similar ejector-enhanced auto-cascade refrigeration cycles in the literature. Advanced exergy analysis reveals that 63.47% of the total exergy destruction is avoidable. When the components of the MEACR cycle are investigated, 56.31% of the exergy destruction is attributed to the endogenous part. The low-temperature cycle (LTC) compressor has the highest avoidable endogenous exergy destruction rate of 12.64 kW with 38.5%.
