Résumé

Steam ejectors are capable of drawing large volumes of vapor within a relatively small space and at a low cost. In this study, the compressor is replaced by a constant-area mixing ejector to reduce the energy consumption in refrigeration cycle. The influence of various parameters on the performance of the system is obtained by an iterative program and reasons are analyzed in this paper. The effect of pressure difference, the difference of evaporation pressure and primary nozzle outlet pressure, on the COP and the exergy loss of every component in system is considered. Finally the key points to optimize the ejector cycle and the minimum exergy loss location to optimize the ejector design are obtained by theoretical research. A better understanding for the real industrial application is provided by this theoretical analysis on the steam ejector refrigeration system and a foundation for the simulation and experimental reach is laid.
