介绍太阳能驱动有机朗肯循环;分析应用于循环的循环工质,主要指出了非共沸混合质的优点;研究有机朗肯循环的性能,得出以下结论:同一组分的非共沸混合工质在蒸发冷凝温度相同时,在不同质量配比下,其循环效率、运行压力、膨胀比是不相同的。
The solar-powered organic Rankine cycle is introduced. The cyclic working fluid used in the cycle is analyzed. The advantages of the non-azeotropic mixture are pointed out. The performance of the organic Rankine cycle is studied. The conclusions are drawn as follows: When the mass of the material is the same at the evaporation and condensation temperature, the circulation efficiency, operating pressure and expansion ratio are different under different mass ratios.
