本文指出了在冷却塔实践中标准化的必要性，以及采用一个共同的基本理论来关联大量的实验数据，并结合现有的实际经验。这种理论在根据在其他服务条件下获得的测试数据计算保证点的性能方面将是非常有价值的。从默克尔关于冷却塔的微分方程式出发，推导出计算冷却塔性能的无量纲基本方程。然后以作者公司开发的曲线形式给出了这一基本方程的图解方法，并对其进行了解释。结果还表明，在一组固定条件下，冷却塔的尺寸不是完全由理论决定的，而是由经济条件构成的最终标准。
This paper indicates the need for standardization in cooling-tower practice and the adoption of a common basic theory for correlation of the vast amount of experimental data, coupled with practical experience now available. Such a theory would be invaluable in calculating performance at the guarantee point from test data taken under other conditions of service. From Merkel’s differential equation for the cooling tower, the author derives a basic dimensionless equation for calculating cooling-tower performance. A graphic method of solution of this basic equation is then given in the form of curves which have been developed by the author’s company as a result of extensive tests which are explained. It is further shown that the size of a cooling tower for a fixed set of conditions is not entirely determined by theory alone, but that economic conditions constitute the final criterion.
