| Abstract: |
| In this study, the working mechanism, performance evaluation indexes, and theoretical models of an ejector are summarized. The effects of the configuration and dimensions of an ejector and its nozzle, suction chamber, constant-area section, and diffuser on the performance are reviewed. Some typical examples of applications of ejector refrigeration systems are described, including single and multi-stage ejector refrigeration, combined compression–ejector refrigeration, combined ejector-absorption refrigeration, and ejector refrigeration systems without pump. Finally, prospective proposals of ejector research are suggested. |
