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2 h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2 h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。
Objective To test the purifying effect of inhalable particles, gaseous formaldehyde and white staphylococcus with multi-function air purifier. The method was tested in a room simulating a hospital environment. Compared with the purification effect of commercial electrostatic adsorption type TA100 air purifier, the control test was carried out. The experiment was completed in a completely simulated simulated on-site air laboratory (space size: 60 m3). Results Homemade air purifier and TA100 purifier 2 hours after startup, the degradation of respirable particulate matter were 81.00% and 76.43%, respectively, in a closed room homemade air purifier on the degradation of gaseous formaldehyde better than the TA100 purifier, homemade Air Purifier and TA100 purifier were killed after 2 h, 99.97% and 94.46% of the people spilled into the room of Staphylococcus aureus. Conclusion The results show that the self-made air purifier has a more satisfactory removal of contaminants tested and is ideal for use in hospitals or other places where air quality is high.
