A cooler network is a significant part in a heat exchanger network, which is also vital to energy consumption and economic performance of the entire chemical manufacturing process. Currently, the work on the optimization of cooler networks chiefly has attached to optimization of circulating cooling water systems. However, few researchers have taken different cooling types with series and parallel configuration into consideration in the process of optimization on cooler networks. On the basis of lectotype among the dry type air cooler, spray type air cooler on behalf of wet type air coolers, and circulating cooling water system, a superstructure-based optimization model with minimizing total annual cost as the objective function is established in this paper, formulated through mixed-integer nonlinear programming. Coolers with series and parallel configuration are allowed to reduce energy and water consumption and improve economic performance. Corresponding case studies show that the model can give a more economic efficient solution of the cooler network.

串联和并联配置不同冷却类型的冷却器网络的优化

冷却器网络是热交换器网络的重要组成部分，这对于整个化学生产过程的能耗和经济性能也至关重要。当前，冷却器网络优化的工作主要与循环冷却水系统的优化有关。但是，很少有研究人员在冷却器网络的优化过程中考虑到具有串联和并联配置的不同冷却类型。基于干式空气冷却器，代表湿式空气冷却器的喷雾式空气冷却器和循环冷却水系统中的选型，本文建立了一个基于上层建筑的优化模型，该模型以年度总成本最小为目标函数通过混合整数非线性规划制定。允许采用串联和并联配置的冷却器，以减少能源和水的消耗并提高经济性能。相应的案例研究表明，该模型可以为冷却器网络提供更经济有效的解决方案。
