摘要
为了提高CO2跨临界循环系统的效率,可以采用双级压缩。分析了给定双级系统的最优工况点,一级节流双级压缩系统的最优中间压力以及最优高压压力随不同参数的变化趋势性能,得到了最优高压压力与最优中间压力的关联式,为双级系统的设计提供了理论支持。
Two-stage compressor is used for improving the efficiency of CO2 transcritical cycle. The optimal working condition point is selected for the given two-stage compression system. It is analyzed that the variety trend of optimal intermediate pressure and optimal high pressure based on the different parameters. The relation between the optimal intermediate pressure and optimal high pressure is introduced for the design of two-stage compression system for CO2 transcritical cycle.
