高效多功能空气净化机对可吸入颗粒物、气态甲醛和白葡萄球菌的净化效果测试

目的 测试多功能空气净化机对可吸入颗粒物、气态甲醛和白葡萄球菌的净化效果.方法 在一个模拟医院环境的房间中测试.与商用静电吸附式TA100空气净化机的净化效果作为对照组进行对比测试,实验是在完全一致的模拟现场空气实验室(空间大小60 m3)中完成.结果 自制空气净化机和TA100净化机开机2h后,对可吸入颗粒物的降解率分别为81.00％和76.43％,在封闭房间中自制空气净化机对气态甲醛的降解效果优于TA100净化机,自制空气净化机和TA100净化机开机2h后分别杀灭了99.97％和94.46％的人为洒入房间的白葡萄球菌.结论 结果显示自制的空气净化机对于所测试的污染物有更为满意的去除效果,是医院或其他对空气质量要求较高地方的理想选择.

Removal of inhalable particulates,gaseous formaldehyde and staphylococcus albus by an efficient multifunctional air purifier

【Objective】 To test the working efficiency of multifunctional air purifier on removal of inhalable particulates,gaseous formaldehyde and staphylococcus albus.【Methods】 Examination was conducted in a simulated hospital room environment.The purification effectiveness of the commercial adsorption/electrostatic-field TA100 air purifier(TA100 purifier) was also investigated for comparison.The experiments were conducted in identical on-site simulation air laboratories each with the space volume of 60 m3.【Results】 The removal efficiency of inhalable particulates of ID purifier and TA100 purifier was 81.07% and 76.43% for two hours of purification,respectively.The effectiveness of ID purifier in purifying gaseous formaldehyde from the enclosed room atmosphere was even better than that of TA100 purifier.Operation of the ID purifier and TA100 purifier for two hours killed 99.97% and 94.46% of the staphylococcus albus artificially sprayed in air room respectively.【Conclusion】 These results indicate that the ID purifier has satisfactory efficiency values for removing all of the contaminants tested,and is an ideal choice for hospitals and other places that require high air quality.
