摘要
目的:为了解采用不同消毒因子的风机盘管空气净化装置对空气中自然菌的消除效果,分别对安装了单一的二氧化钛网、二氧化钛网加紫外线灯和二氧化钛网加紫外线灯加高压静电的风机盘管空气净化装置进行现场实验。将通风管道内一次性通过的空气中自然菌平均消除率进行对比分析,比较三种设备对空气中的自然菌消除效果。方法:按《公共场所集中空调通风系统卫生规范》(卫生部2005)进行现场试验。结果:1、安装了二氧化钛网的风机盘管空气净化装置对空气中自然菌的消除率为30.4%。2、安装了二氧化钛网加紫外线灯的风机盘管空气净化装置对空气中自然菌的消除率为50.02%。3、安装了二氧化钛网加紫外线灯加高压静电的风机盘管空气净化装置对空气中自然菌的消除率为95.08%。结论:安装了二氧化钛网的风机盘管空气净化装置对空气中自然菌具有一定的消除效果。加装紫外线灯后,消除效果有所增强。在风机盘管中安装二氧化钛网、紫外线灯和高压静电的空气净化装置结构更为复杂,对空气中自然菌消除效果最佳,能够达到消毒水平。
Objective：To learn fan-coil air purifying units with different disinfection genes′efficacies of perishing the natural bacteria in the air,the units have been installed with single titanium dioxide（in short TiO2）,TiO2 plus UV lamp,and TiO2 plus UV lamp plus high voltage electrostatic respectively and the field experiments have been taken.Through a comparative analysis on their average perishing rates of natural bacteria after the air had passed once in the ventilation duct,the different efficacies of the three units have been indicated.Methods：According to specification for hygiene central air conditioning ventilation system of public place（Ministry of Heath 2005）,field experiments have been conducted.Results：1.The perishing rate of natural bacteria is 30.4% for the fan-coil air purifying unit with single titanium dioxide.2.The perishing rate of natural bacteria is 50.02 % for the fan-coil air purifying unit with TiO2 plus UV lamp.3.The perishing rate of natural bacteria is 95.08 % for the fan-coil air purifying unit with TiO2 plus UV lamp plus high voltage electrostatic.Conclusion：The fan-coil air purifying unit with single titanium dioxide has certain efficacy of perishing the natural bacteria in the air.After adding UV lamp,the efficacy has been increased.But if the fan-coil installed TiO2,UV lamp,and high voltage electrostatic,the air purifying unit has a more complex structure and it can achieve better efficacy of perishing the natural bacteria in the air which meet the requirement of air disinfection.
