负离子发生器对空气的净化作用

PURIFICATION OF AIR BY ANION GENERATOR

对负离子发生器净化空气效果进行现场观察。测定结果表明,负离子发生器开机40分钟后,室内空气中负离子明显增加,尘埃与细菌减少。

Observation of air-purifying effect of anion was carried out in three(A, B and C) consulting rooms of the hospital. The experiments were repeated for 6 times in each consulting room when it was occupied. Air samples were taken after 40 min operation of anion generator to measure the anion content of air, which was found to be more than 1000 times above the background value. The nearer the air to the anion generator, the higher the concentration of anion. Of the three consulting rooms, the concentration of dust particles in rooms A and C decreased apparently, while that in room B decreased to a level without significant difference from the background value. This may be related with more acivities of persons in room B than in the other two. The concentration of bacteria in all these three consulting rooms decreased significantly as compared with the background value. The results indicate that the anion has certain purifying effect on air. Since anion is beneficial to human body and has no adverse effect, it can be used widely for purification of air in hospitals in order to reduce bacterial contamination.
