摘　　要：本文在多股流换热器精确数学控制的基础上,针对板翅式平行流多股流换热器,从最小能耗的角度确定辅助流体间的最佳调节组合建立优化目标函数,对其进行了运行优化的研究。即当目标流体入口参数发生工况变动后,为了确保其出口的工艺条件,通过调节不同的辅助流体及不同辅助流体间的调节组合来寻求能量投入量最小,同时引入优化算法,可以快速的求解出最小能耗下辅助流体间的最佳调节组合。Based on the accurate mathematic control in multi- stream heat exchangers, a object function is made by adjusting proportion of assistant fluids to obtain minimum energy consumption for plate - fin parallel heat exchangers, and optimization operation is studied. When the inlet parameter of object fluid changes, minimum energy consumption is sought by adjusting different assistant fluids or modulating proportion among assistant fluids to ensure that outlet parameter of object fluid meets process requirement. At the same time, optimization methods are adopted, which can rapidly acquire the optimization proportion of assistant fluids under the minimum energy consumption.
