摘要
以带填料的闭式冷却塔为分析对象,基于冷却塔热质交换原理及能量平衡方程,结合其热质交换数学模型以及各项冷却塔传热性能评价指标,以冷却塔额定工况的换热能力为比较基准,重点分析了冬季室外气象参数(干球温度、湿球温度)对冷却塔热湿交换性能的影响。在此基础上,进一步分析了闭式冷却塔在上海地区冬季运行的具体性能。
This paper investigated the closed cooling tower with packing, and analyzed the effect of winter outdoor meteorological parameters on the performance of cooling tower based on the principle for heat and mass transfer of the closed cooling tower with packing, the mathematical model for heat and mass transfer and the evaluating indicator on the basis of the performance under rated conditions of the cooling tower in winter. And then, analyzed the operation performance of the closed cooling tower with packing in winter of Shanghai for further study.
