摘要
目的观察空气模拟现场察紫外空气消毒器的净化除菌相关性能。方法采用空气微生物采样器采样和空气模拟现场消毒试验方法,对某紫外线循环风消毒器空气模拟现场消毒效果及其相关性能进行检测。结果该紫外线循环风消毒器内置高强度紫外线灯与高效过滤器,在20 m^3房间内启动运行45 min,对人工污染在空气中的白色葡萄球菌的平均杀灭率为99.99%。该消毒器运行期间房间环境中泄漏紫外线辐射强度<1μW/cm^2,产生臭氧量<0.02 mg/m^3。结论该空气消毒器对模拟现场房间内空气中人工污染菌杀灭效果符合相关标准要求,环境无紫外线泄漏和臭氧产生。
Objective To observe the disinfection related efficacy of the air disinfection disinfector. Methods The Anderson sampling method,simulated field test,germicidal test and other related tests were carried out to observe the disinfection and related properties of the UV recirculating air disinfector. Results The average killing rate of the air disinfector on Staphylococcus albus was 99. 99% for 45 minutes. The ultraviolet radiation leak was 〈1 u W/cm2,and in 〈20 m3 room,the ozone leakage was 0. 02 mg/m3 within an hour. Conclusion The air disinfection effect of this air disinfector can comply with relevant standards. There are no UV leakage and Ozone leakage in the environment.
