为了解通风空调系统循环空气的消毒方法的效果,采用现场试验的方法对高效过滤、激光照射、静电吸附、紫外线照射和臭氧熏蒸等空调空气消毒方法进行了观察。结果,高效过滤和激光照射方法一次通过时自然菌消亡率大于90%;静电吸附经过运行15 m in,除菌率为62%;紫外线照射方法在消毒系统运行90 m in后对自然菌消除率大于90%。臭氧空调消毒装置在臭氧量保持3.48 mg/m3,运行90 m in,对自然菌消除率可达到90%以上。结论,空调系统消毒装置以激光和高效过滤除菌效果最好,紫外线辐射、静电及臭氧均需要运行一定时间之后才显除菌效果。
In order to understand the effect of the disinfection method of circulating air in ventilation and air conditioning system, the method of field test was used to observe the air-conditioning air disinfection methods such as high efficiency filtration, laser irradiation, electrostatic adsorption, UV irradiation and ozone fumigation. The results showed that the rate of natural bacteria was more than 90% after one pass of high-efficiency filtration and laser irradiation, the rate of bacteria removal was 62% after 15 minutes of electrostatic adsorption, and the rate of natural bacteria elimination after UV irradiation was 90 minutes Greater than 90%. Ozone air conditioning disinfection device in the amount of ozone to maintain 3.48 mg / m3, run 90 m in, the elimination rate of natural bacteria can reach 90%. Conclusions: Air conditioning system disinfection device with laser and high efficiency filter sterilization best, UV radiation, static electricity and ozone are required to run a certain period of time before the removal of bacteria effect.
