目的:了解集中空调等离子净化消毒装置对空气中自然菌的消除效果。方法:按《公共场所集中空调通风系统卫生规范》(卫生部2006)进行现场试验。结果:当风速分别为1m/s、2m/s、3m/s时,仅安装等离子发生器的净化消毒装置对空气中自然菌的平均消除率分别为42.92%,35.71%和23.28%;安装等离子发生器和中效过滤器的净化消毒装置对空气中自然菌的平均消除率分别为96.73%、95.53%和90.38%。结论:仅安装等离子发生器的净化消毒装置对空气中的自然菌仅具有一定的消除效果,消除率远低于90%,达不到消毒水平;安装等离子发生器和中效过滤器的净化消毒装置对空气中自然菌消除率均在90%以上,达到消毒水平。
Objective: To understand the effect of central air conditioning plasma cleaning and disinfection device on the elimination of natural bacteria in the air. Methods: According to “public places centralized air conditioning and ventilation system health norms” (Ministry of Health 2006) for field trials. Results: When the wind speed was 1m / s, 2m / s and 3m / s respectively, the average removal rates of natural bacteria in the air were only 42.92%, 35.71% and 23.28% The average disinfection rate of natural bacteria in air by purifying and disinfecting devices of generator and medium efficiency filter were 96.73%, 95.53% and 90.38% respectively. Conclusion: Only the plasma disinfection device installed on the natural bacteria in the air only have a certain elimination effect, the elimination rate of much less than 90%, reaching the level of disinfection; installation of plasma generators and filter disinfection purification Installation of natural bacteria in the air to eliminate more than 90%, reaching the level of disinfection.
