评价标准型冷却塔冷却能力时水温差的修正

Correction of water temperature difference for evaluation of cooling capacity of standard cooling towers

根据冷却原理及基本公式，给出了不查图表由计算求修正水温差的实用公式，并与查图表方法进行了比较。

On the basis of cooling theory and relevant fundamental equations,formulas are suggested forcalculating the correction of water temperature difference between entrance and exit of standard coolingtowers without using the plotting chart.Comparison of results from calculation and plotting chart are presented.
