“…One of the main reasons for this issue is because of the difficulty in improving ejector performance with relatively low suction pressure. Major performance improvements may be achieved by increasing the ejector suction pressure, as proved by many experimental and simulation results [4], [5].…”

This paper presents a performance improvement potential analysis of a booster-assisted ejector refrigeration system. Both conventional and advanced exergy analysis methods are used to obtain detailed information about the interactions among system components and the real improvement potential of the system. The results show that 61.6% of the system exergy destruction is caused by the components themselves. Furthermore, 55.5% of the overall exergy destruction can be avoided by improving component efficiencies. The ejector has the highest improvement priority, followed by the booster and the condenser. The influences of operational conditions on the ejector performance are also discussed. The avoidable exogenous part in ejector exergy destruction could be reduced by increasing the temperature of the motive flow, increasing the discharge pressure of the booster or decreasing the inlet water temperature in the condenser. INDEX TERMS Ejector, booster, refrigeration, improvement potential.

“…The exergy method of thermodynamic analysis allows one to take into account the energy potential (qualitative characteristics) of thermal processes [3,4,5,6]. To date, the most effective method of parametric optimization of heat and power processes is the method of integration of heat fluxes (pinch method) [7,8].…”

The article is devoted to the issue of thermodynamic optimization of heat transfer systems. Optimization is carried out by an exergy pinch method. This method includes the advantages of exergy analysis and pinch method. Exergy analysis takes into account the quantitative and qualitative characteristics of thermal processes, the pinch method allows structural and parametric optimization of heat transfer systems. The article presents a mathematical model for optimization by exergy pinch analysis. This model allows automated system optimization. Exergy pinch analysis allows more efficient use of energy and resources at the enterprise, which is relevant today.
