| 摘 要： | 管式蒸发冷却器在空调、化工、石油等行业中有着广泛的应用。本文首先根据最优化方法建立了管式蒸发冷却器优化设计的数学模型,并分析了约束条件的确定、优化变量的选取及模型的求解方法。然后针对某一算例,利用该模型分析了结构参数对管式蒸发冷却器冷却性能的影响。根据优化设计的结果可知:换热器的长度、宽度以及管间距变化时,目标函数有时呈现振荡性变化的规律。结构参数的取值原则应综合考虑材料费用、运行能耗以及冷却器的冷却能力。优化设计的结果可以为管式蒸发冷却器的设计提供参考,达到节约初投资及降低能耗的目的。

| Abstract: | Tube evaporative cooler is widely used in the area of air-conditioning,chemical,petroleum industry,etc.This article firstly established the mathematic model based on the optimization method,analyzed how to confirm the constraints,choose the optimize variables and get the result.Then take a certain example,analyze structure parameter's influence on tube evaporative cooler cooling performance.The optimization results demonstrate that when the length,width and the space between tube and tube of heat-exchanger changes,the objective function presents the vibration tendency.The structure parameter should take into account the material cost,energy consumption and cooling performance.As a reference for engineering design of tube evaporative cooler,the optimization design can save energy and materials. |
