            摘要:

            4台空气净化器进行了实验研究,分析了不同相对湿度下空气净化器的现场净化效率、洁净空气量、有效净化效率和净化能效,以及细颗粒物(PM2.5)的自然衰减规律与净化衰减规律。结果显示:在相对湿度为35%60%的范围内,滤网式空气净化器的现场净化效率随着相对湿度的增大而增大,而静电除尘式空气净化器的现场净化效率随着相对湿度的增大而减小;对于滤网式空气净化器,其洁净空气量及有效净化效率随着相对湿度的增大而增大;PM2.5的自然衰减速度随着相对湿度的增大逐渐加快,滤网式空气净化器对PM2.5的净化衰减速度随着相对湿度的增大而加快,静电除尘式空气净化器对PM2.5的净化衰减速度随着相对湿度的增大而逐渐放缓。

            Abstract:

            Carries out an experimental study on four air purifiers, analyses the field purification efficiency, clean air delivery rate, effective purification efficiency and purification energy efficiency of the air purifiers at different relative humidity, as well as the natural attenuation law and purification attenuation law of PM2.5. The results show that when the relative humidity ranges from 35% to 60%, the field purification efficiency of the filter type air purifier increases with the increase of relative humidity, but that of the electrostatic precipitator air purifier decreases with the increase of relative humidity. For the filter type air purifier, the clean air delivery rate and effective purification efficiency increase with the increase of relative humidity. The natural attenuation rate of PM2.5 increases with the increase of relative humidity. The PM2.5 purification attenuation rate of the filter type air purifier increases with the increase of relative humidity, and that of the electrostatic precipitator air purifier gradually slows down with the increase of relative humidity.
