摘要： 根据换热网络分级超结构模型，提出了针对冷却水换热网络的3种改进换热模型.与传统的分级结构不同之处在于水网络不需要公用工程的设计，冷流只包括冷却水.并且3种设计方法均考虑了水的分流和汇流，实现了水的非等温混合.结构二和结构三可以实现换热器中水的分阶段混合.通过权衡公用工程费用和投资费用的关系来确定最小年度总成本.使用粒子群算法优化了换热水网络中的热负荷和水的质量流量.通过两个案例可知，提出的3种改进结构费用低于前人的研究结果，案例1中结构3的费用最低，案例2中结构1的经济性最优.

关键词: 冷却水网络；分级超结构；非等温混合；粒子群算法；年度总成本

Abstract: Based on the stage-wise superstructure model of the heat exchanger network， three improved cooling water exchange networks are proposed. The hot and cold utilities are dispensable and the cold stream only contains cooling water， which is different from the traditional heat exchanger synthesis. The three design approaches all consider the water splitting and mixing to achieve the non-isothermal mixing of water. The second and third configuration can achieve phased water mixing. The minimum total annual cost is determined by the trade-off utility cost and capital cost. Particle swarm optimization (PSO) is demonstrated to optimize the heat load and the water mass flow rate in the water network. Two cases show that the total annual cost of the three improved structures proposed is better than the previous research results and in Case 1， configuration 3 has the lowest cost， and in Case 2， configuration 1 has the best economic performance.

Key words: cooling water network; stage-wise superstructure; non-isothermal mixing; particle swarm optimization (PSO); total annual cost
