摘要

针对复杂换热网络全局优化中可操作性、优化效率与优化质量三者间的矛盾问题，基于换热网络优化中的最佳温位匹配的原则，提出了一种复杂换热网络分步优化方法。该方法将复杂的网络集成问题分解为以冷(热)流体数目为基础的多个单一流体匹配优化的子问题，以最优匹配优选的原则进行网络结构的分步生成，最终获得网络的总体结构。结果表明，以优选匹配的换热网络结构优化结果优于焓差匹配、温位匹配的结果，匹配的原则中，优选匹配要作为首选的匹配原则，可以避免前两种匹配原则上的匹配失当，该方法极大地提高了复杂换热网络优化的可操作性，优选匹配顺序使得分步优化能够取得更高的质量。

Abstract

Due to the paradoxical relationship among operability，optimization efficiency and quality for complex heat exchanger network global optimization，a fractional matching optimization method of complex heat exchanger network was proposed with the optimal temperature principle.The complex network integration problem was decomposed into multi-single fluid matching optimization sub problem based on the number of cold/hot fluid.The network structures were stepwise generated with optimal matching priority principle and the general network structure could be obtained finally.The results showed that optimizing selection matching principle could provide better heat exchanger network structures than enthalpy difference matching and temperature matching for avoiding matching misconduct.This method could greatly improve the operability of complex heat exchanger network and the matching sequence optimizing selection could promote the fractional optimization quality.
