静电空气净化器实际运行效率研究

摘要

Two typical electronic air cleaner samples were tested for continuous operation experiment.By continuous monitoring the actual operation condition,the dynamic efficiency of electronic air cleaners was studied.It was found that the filtration efficiency of cleaner samples decayed rapidly,which decreased to half in first 1 ～2 weeks,and then trended towards stability fluctuating on certain efficiency ranges.The actual filtration efficiency was far below the initial one.%本文选取了两台典型的静电空气净化器作为样本,通过持续监测样本的运行状态和颗粒物一次净化效率,研究了静电空气净化器在实际运行过程中的净化效率及效率衰减等问题.结果显示,静电空气净化器的初始一次净化效率较高,但在开始使用后的1～2周内效率急剧下降,衰减至初始效率的一半左右,随后趋于稳定在某一区间内波动,实际净化效率远低于初始值.
