摘　　要：以系统热效率最大为计算原则,提出以R123为工质的有机朗肯循环系统最佳再热压力的确定方法.通过计算机编程模拟,简化数学条件,建立了最佳再热压力的数学模型,并通过实验验证了模型的可靠性,可为机组运行或进行节能改造提供一定的数值依据或参考,同时为采用其它工质的朗肯循环优化提供方法指导.A mathematical model of optimal reheating pressure in Organic Rankine Cycle system with working fluid R123 is proposed according to the calculation principle of best thermal efficiency. Then the mathematical model of optimal reheating pressure is finally established through computer programming simulation, simplified mathematical conditions, and the experimental results verified the reliability of the models. It can provide some numerical basis or reference for the unit operation and energy saving transformation and also provide methods for the optimum of Rankine Cycle system with other working fluilds.
