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。 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。
