直接蒸发式冷风扇的携菌与除菌性能实验研究

Experimental Study on the Bacteria Carry-over and Removal Performance of Direct Evaporative Coolers

对直接蒸发式冷风扇空气系统与水系统之间细菌的传播及去除进行了实验研究。研究表明,直接蒸发式冷风扇不会将循环水中的细菌通过蒸发冷却填料带入送风气流中,甚至在一定程度上还会将吸入空气中的细菌过滤去除。同时,还讨论了如何防止细菌传播以及除菌的具体方法。

In this paper, the carry-over and removal of bacteria between the air system and water system in direct evaporative cooler were studied experimentally. Research shows that bacteria in the circulating water will not be carried by air flow through evaporative pad during direct evaporative cooling, and even to some extent, bacteria in the intake air will be removed in this process. Meanwhile, the paper also discusses the specific methods on how to prevent the spread of bacteria and sterilization.
