摘　　要：随着对工业生产成本控制要求的不断提高,换热网络优化的深入研究已经引起了越来越多研究人员的重视。在换热网络综合过程中考虑换热器的详细设计是换热网络综合细化深入研究的一个重要方面,可以降低换热网络的年度总费用,并且提高换热网络综合结果的实际可行性。本文通过文献中的算例结果分析,考虑换热器详细设计的换热网络综合的总费用明显低于不考虑换热器详细设计的总费用,阐述了换热网络综合中考虑换热器详细设计的必要性,强调了换热器的详细设计对换热网络综合的影响。文献中考虑换热器详细设计进行换热网络综合时主要采用了夹点分析法和数学规划法,夹点分析法综合换热网络虽然使包含换热器设计的换热网络结构变得简化易于求解,但是无法保证结果是最优解,而数学规划法综合换热网络能有效的考虑换热器详细设计对换热网络综合的影响,但是考虑换热器详细设计也大大增加了模型的复杂性,本文对此进行了对比和评述,同时认为深入研究换热网络细化设计研究并利用快速而高效的算法搜索全局最优解是未来研究方向。With the increasing requirement on the controlling of industrial production cost, a thorough study of heat exchanger network has been obtained great interests for more and more researchers, it is an important aspect in the deep study of heat exchanger network synthesis that considering detailed heat exchanger design, it can reduce the annual total cost of the heat exchanger network by considering detailed heat exchanger design, and it can improve the practical feasibility for the results of the heat exchanger network synthesis. The necessity of considering detailed heat exchanger design was verified with an example which came from a literature, the cost of the heat exchanger network with a detailed heat exchanger design was significantly lower than that without detailed heat exchanger design, and the influence of detailed heat exchanger design on heat exchanger network synthesis was emphasized in this article. Pinch analysis method and mathematical programming method were used for the heat exchanger network synthesis considering detailed heat exchanger design in the literatures, heat exchanger network synthesis with pinch analysis method made the structure of heat exchanger network with detailed heat exchanger design easy to be solved, but it cannot guarantee that it was the global optimal solution. Heat exchanger network synthesis with mathematical programming method was effect to consider the influence of the detailed heat exchanger design on the heat exchanger network synthesis, but it made the mathematical model more complex by considering detailed heat exchanger design, it was compared and reviewed in this article. The future research development was pointed out to have a deep study in detailed heat exchanger network synthesis and get a global optimal solution with a fast and efficient algorithm.
