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%.Englishinfo:eu-repo/semantics/closedAccessrefrigeration, auto-cascade refrigeration, ejector, exergy analysis, advanced exergy analysisEjectorAuto-Cascade RefrigerationAdvanced Exergy AnalysisRefrigerationExergy AnalysisArticle
