摘　　要：采用热力循环三维构建方法作为功冷并供系统的优化策略,分析了非共沸工质的组分特性对喷射式功冷并供系统性能的影响。对考虑工质组分质量分数变化的三维热力循环与传统二维热力循环系统性能进行对比。结果表明:采用热力循环三维构建方法可以使系统性能明显提高;蒸发温度为413.15 K时,系统增加分离器后热效率从33.2%提升到35.25%。Using the three-dimensional(3 D) construction method of thermodynamic cycle as an optimization strategy for a combined power and ejector-refrigeration system, the effects of the composition of non-azeotropic working fluid on the performance of the combined system were analyzed, while a comparison was conducted between the performance of a 3 D thermal cycle system that takes into account the changes in the composition of the working fluid and that of a traditional 2 D thermal cycle system. Results show that the 3 D construction method of thermodynamic cycle can significantly improve the performance of the combined power and ejector-refrigeration system. When the evaporation temperature is 413.15 K, the thermal efficiency of the system would increase from 33.2% to 35.25%, after a separator is added to regulate the components.
