| 摘 要： | 针对于多股流换热器网络的应用优势,本文在衍生网络优化方法基础上,提出了考虑最佳入口温度的多股流换热器循环优化方法,即利用多股流换热器网络小面积换热器合并而不产生固定投资费用这一特点,将优化结果中存在公用工程的流体返回到另一种流体的入口并与其入口流体进行循环优化。结果表明,这种优化方法能够进一步发挥多股流换热器网络的优点,得到年综合费用更小、运行费用更低的网络结构。

| Abstract: | As to the advantage in application of multi-stream heat exchanger networks,the cycling optimization method with optimal inlet temperature is presented based on the derived Network Optimization Method in the paper.With the characteristic that combination of small area heat exchangers don't bring cost of fixed investment,the stream with utility costs from optimization structure returns the inlet of the other stream and is optimized with it.The results show that the method can bring more advantage of multi-str... |
