大门空气幕计算方法的比较分析

Comparison of Methods of the Calculation of Air Curtains

空气幕装置的喷口送风量是一个与很多因素有关的变量，计算方法较多且计算结果相差也较大。本文通过对三种常用计算方法的比较分析，认为以自然通风原理为基础的空气幕计算方法是一种较合理的计算方法。

The capacity of spray supply air of air curtain installation is connected with many factors. And its calculation methods are different, furthermore, the results are different from each other. By analysing and comparing the three calculation methods that are generally used, this article shows us that the calculation method based on the natuaral ventilation principle is reasonable.
