TA系列空气净化机对室内空气净化效果的应用观察
Efficacy of TA series of air purifiers in purification of indoor air
【摘要】 目的观察TA系列空气净化机对室内空气中可吸入颗粒物、白葡萄球菌、甲醛的净化效果。方法选取3间20m2模拟现场空气实验室,随机分为A试验间(运行TA100空气净化机2h)、B试验间(运行TA1000空气净化机2h)和对照间(无空气净化机)进行测试,采用3511型压电天平式粉尘测定仪测量可吸入颗粒物降解率,FA-1式多级空气撞击式采样器测量白葡萄球菌杀灭率,应用4160型甲醛现场分析仪分析甲醛降解率。结果TA100空气净化机开机1h和2h可吸入颗粒物降解率分别为47.00%和73.60%,TA1000空气净化机则分别为56.00%和77.80%,均显著高于对照组的0%和3.40%(P<0.01),TA1000降解率优于TA100(P<0.05);TA100和TA1000空气净化机开机2h白葡萄球菌杀灭率分别为97.87%和99.99%,而对照组仅为48.25%,净化机组均优于对照组(P<0.01),但TA100和TA1000差异无显著性(P>0.05);TA100和TA1000空气净化机开机2h甲醛降解率分别为74.00%和83.00%,显著高于对照组的7.50%(P<0.01),TA1000降解率优于TA100(P<0.05)。结论TA系列空气净化机有优良的空气净化效果,TA1000的可吸入颗粒物降解率、甲醛降解率优于TA100。
【Abstract】 【Objective】To observe the efficacy of TA series of air purifiers on inhalable particles, staphylococcus, and formaldehyde. 【Methods】3 air stimulated cabins was selected as the study objects and were randomly divided into 3 groups, group A (TA100 air purifier), group B (TA1000 air purifier), and blank control group C (no air purifier). And then the degradation rates of inhalable particles, staphylococcus and formaldehyde of each group were measured.【Results】The 1h degradation rates of inhalable particles of group A and B is 47.00% and 56.00% respectively, The 2h degradation rates of group A and B is 73.60% and 77.80% respectively. The degradation rates of both groups were significantly higher than the blank control group C (P <0.01). The 2 h degradation rates of Staphylococcus of group A and B is 97.87% and 99.99% respectively, both of which were significantly higher than that of blank control group C (P <0.01). The 2h degradation rates of formaldehyde of group A and B is 74% and 83% respectively. Both were significantly higher than that of blank control group C (P <0.01).【Conclusion】The TA series air purifiers are fit for purification of indoor air. Furthermore, TA1000 is better than TA100 in degradation rates of inhalable particles and formaldehyde.
