摘要：

Ejector refrigeration cycle (ERC) with advantages of simple structure and low cost holds great application potential in cascade/hybrid cycles to improve the overall system performance by removing or recovering the heat from the main cycle. In this paper, a theoretical and experimental investigation of the ERC as a part of a cascade system was carried out. The operating parameters were optimized. The experimental ERC test rig was designed, developed and investigated at high evaporating temperatures and wide ranges of operating conditions. The influence of operating conditions on the efficiency of the ejector and ERC was analyzed. Experimental results and analysis in this study can be helpful for the application and operating condition optimization of ERC in cascade/hybrid refrigeration systems.
