In a recent article, Gonçalves et al., introduced a linear and rigorous methodology for equipment design, in particular shell-and-tube heat exchanger. Here, we explore its application to air coolers, a problem that we solve globally for the first time. Because the approach is linear, results are globally optimal. The objective function is the total annualized cost. The constraints include the thermal and hydraulic modeling of the process stream flow in the tube bundle and the air flow through the finned surface. In addition, we worked on reducing computing time, through an analysis of different alternatives for the description of the original discrete variables organized in sets of binary variables. The performance of the proposed approach is illustrated through its comparison with an air cooler described in the literature. © 2017 American Institute of Chemical Engineers AIChE J, 2017

设计过程设备的全球最佳线性方法:空气冷却器的情况

在最近的文章中,Gonçalves等人介绍了一种用于设备设计的线性且严格的方法,特别是管壳式换热器。在这里,我们将探讨其在空气冷却器中的应用,这是我们首次在全球范围内解决该问题。因为该方法是线性的,所以结果是全局最优的。目标函数是年度总成本。约束条件包括管束中工艺流的热力和水力模型以及通过翅片表面的空气流。此外,我们还通过分析不同的替代方法来描述以二进制变量集形式组织的原始离散变量,从而减少了计算时间。通过与文献中描述的空气冷却器进行比较,说明了所提出方法的性能。AIChE的Ĵ,2017年
