Improving the energy and exergy performance of refrigeration cycles has become increasingly important for industrial and low-temperature applications. In this context, this study presents a comprehensive advanced exergy analysis of an ejector intercooler refrigeration cycle (EIRC), marking the first application of such an approach to this configuration in literature. The system integrates an ejector between the high- and low-temperature stages to improve pressure recovery and reduce throttling irreversibilities, thereby enhancing overall performance. The total exergy destruction of the cycle was calculated as 2.075 kW, with the most significant losses occurring in the evaporator (0.397 kW), condenser (0.384 kW), and high temperature cycle (HTC) compressor (0.372 kW). The HTC ejector also exhibited notable destruction at 0.302 kW. The advanced exergy breakdown revealed that 61.18% of the losses were exogenous, and 71.53% were avoidable, with 37.04% being both avoidable and exogenous, indicating strong potential for system-level optimization. Importantly, while conventional exergy efficiency was calculated as 59%, the advanced exergy efficiency increased to 87%, reflecting a 50% relative improvement. These findings demonstrate the viability of EIRC systems and highlight the importance of integrated design strategies for future performance enhancements.
