【摘要】 室内外空气品质问题日益受到社会广泛关注,各种类型的空气净化装置也在不同程度上缓解了空气污染问题,以产生负氧离子为主的保健设备理论上也具备空气净化的效果。采用标定过的PM_2.5测试仪跟踪记录了不同工况下负氧离子发生器的辅助空气净化效果。通过测试室外不同污染程度下,室内PM_2.5在负氧离子发生器运行时的衰减规律,分析负氧离子发生器分别摆放在室内3个不同位置时对PM_2.5的净化效果。研究表明:负氧离子发生器清除室内PM_2.5的效果较好,放置于室内中间位置比放置于中间靠边位置时的净化效果更好,而放置于窗边角落位置时,净化效率会降低。更多还原

【Abstract】 The indoor and outdoor air quality problem attracts more and more attention, and various types of air purification devices also alleviate air pollution to varying degrees, and in theory, the health equipment that produces negative oxygen ions also has the effect of air purification. The auxiliary air purification effect of negative oxygen ion generator under different working conditions was tracked and recorded by the calibrated PM_2.5 tester in this paper. By testing the attenuation law of indoor PM_2.5 in the operation of the negative oxygen ion generator under different outdoor pollution degrees, analysis of the purification effect of the negative oxygen ion generator on PM_2.5 was made when it was respectively displayed in three different positions indoor. The result showed that: negative oxygen ion generator had a good effect on cleaning indoor PM_2.5, and the cleaning effect was better when placed in the middle of the room than that when placed in the middle-to-side position, while the cleaning effect would be reduced when placed in the corner beside the window.更多还原
