不利条件下冷却塔通风效果CFD模拟优化分析

冷却塔的摆放一直是困扰设计人员的难题,从建筑外观以及运行噪音等角度考虑,往往倾向于将冷却塔放置在比较隐蔽的区域。将冷却塔放置于四周封闭仅顶部开敞的空间内是比较极端的工程实例。针对这样一个实际工程,本文首先使用CFD软件模拟分析了冷却塔的通风效果。而后,在对现状工况进行评估的基础上,提出了改造措施,为实现良好的空调效果提供了可靠保证。改造后良好的运行效果证明了改造措施的正确性。

CFD Optimization Analysis on Ventilation Performance of Cooling Tower in Disadvantageous Conditions

The placement of cooling tower is always a difficult problem which puzzles designers.The cooling tower is usually placed in a covert region when the building appearance and operational noise are considered.Placing the cooling tower in a closed space with only an open roof is an extreme project example.In this paper,the ventilation performance of cooling tower in the above mentioned project was simulated and analyzed by CFD.Basing on the evaluation of present situation,retrofit measures were proposed,which could successfully improve the working environment and guarantee the air-conditioning performance.In addition,the effectiveness of retrofit measures was validated by the well operational performance.
