有机朗肯循环是有效的低品位能源利用方式，有机朗肯循环的流程设计和参数的选择对循环效率有很大影响，其中主蒸汽参数是最重要的热力循环参数。针对循环参数选取、主蒸汽过热对循环效率与余热回收效率的影响特性，建立了有机朗肯循环模型，并利用 EES 建立饱和蒸汽循环与过热蒸汽循环的计算方程，通过变参数计算得到有机朗肯循环主蒸汽参数与循环效率和余热回收率的对应曲线，并比较四类工质的热力循环特点总结有机质热力特性规律。

Organic Rankine cycle is an effective way for low thermal energy utilization, . The process design of Organic Rankine Cycle and the selection of its parameters have great influence on cycle efficiency. The Main steam parameter is the most important Thermodynamic cycle parameter. The Organic Rankine cycle model was built ac-cordingly. The accounting equations to saturated steam cycle and superheated steam cycle were built by EES, The corresponding curves to ORC main steam parameters with cycle efficiency and waste heat recovery rate were ac-quired through variable parameter calculation. The thermal characteristic law of organic fluids was acquired by comparing the four organic fluids thermal cycles.
