摘　　要：为了解紫外线循环风空气消毒器对室内空气消毒的效果,采用现场消毒试验和理化检验方法对其杀菌效果和紫外线辐照强度等进行了检测。结果,该空气消毒器内高强度紫外线灯管下方垂直距离2 cm处辐照强度平均值为13 092μW/cm2;空气消毒器启动120 m in,其周围空气中臭氧浓度平均值为0.02 mg/m3。紫外线循环风空气消毒器开启120 m in,对空气中人工污染的白色葡萄球菌的平均杀灭率为99.93%,自然衰亡率平均为48.99%。启动空气消毒器作用120 m in,对室内空气中自然菌的平均杀灭率为91.52%。结论,该紫外线循环风空气消毒器对室内空气中白色葡萄球菌和自然菌都具有良好杀灭效果。In order to know the efficacy of Ultraviolet Circulating Wind Air Disinfector in disinfection of indoor air, field disinfection test and physicochemical examination method were used to examine its germicidal efficacy and ultraviolet radiation intensity. Results： The radiation intensity at the point 2 cm perpendicularly below the high - intensity ultraviolet lamp in the Air Disinfector was 13092 μW/cm^2 in average. Operation of the Air Disinfector for 120 min produced ozone concentration 0.02 mg/m^3 in air surrounding it and killed 99.93% in average of Staphylococcus albus in artificially contaminated air, while the natural decay rate of the bacteria was 48.99% in average. Operation of the Air Disinfector for 120 min eliminated 91.52% in average of the natural bacteria in indoor air. Conclusion： The Ultraviolet Circulating Wind Air Disinfector has good efficacy in killing Staphylococcus albus and natural bacteria in indoor air.
