【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。更多还原

【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.更多还原
