Review on Ejector Efficiencies in Various Ejector Systems
نویسندگان
چکیده
The efficiency of the ejector cycle is very sensitive to the ejector efficiency. This paper provides a literature review on ejector efficiencies in various ejector systems, such as vapor compression systems, solar driven ejector systems. The definitions of overall ejector efficiency and ejector component efficiencies in literature are summarized. The assumed constant ejector component efficiencies used in the ejector modeling, and the empirical correlations of the ejector efficiencies developed based on the external measured parameters are summarized and compared; the methods of determining energy efficiencies are summarized. The effects of ejector geometries, operating conditions and working fluid characteristics on ejector efficiencies are discussed. This review will be useful for further research on ejector efficiency, optimal design and control of ejectors and ejector systems.

متن کاملEffect of Suction Nozzle Pressure Drop on the Performance of an Ejector-Expansion Transcritical CO2 Refrigeration Cycle
The basic transcritical CO2 systems exhibit low energy efficiency due to their large throttling loss. Replacing the throttle valve with an ejector is an effective measure for recovering some of the energy lost in the expansion process. In this paper, a thermodynamic model of the ejector-expansion transcritical CO2 refrigeration cycle is developed. The effect of the suction nozzle pressure drop ...

متن کاملAnalysis and Comparison of Two-Phase Ejector Performance Metrics for R134a and CO2 Ejectors
Two-phase ejectors have been gaining increased attention in recent years due to their ability to directly improve the COP of the cycle. Of common interest in two-phase ejector studies is how the ejector improves cycle COP. However, less emphasis is often given to the performance of the two-phase ejector itself. The amount of COP improvement offered by an ejector cycle is very strongly influence...
