空气过滤器效率的气溶胶计数法评价
Evaluation of aerosols counter method for efficiency of air filter
摘要：
通过分析大气尘计数法和气溶胶计数法的特点，指出后者代替前者的必要性。尘源特性和气溶胶发生器是气溶胶计数法的核心，对比了ANSI/ASHRAE 52.2-1999和EN 779:2002标准中的尘源和气溶胶发生器。介绍了GB/T 14295—2008《空气过滤器》采用气溶胶计径计数法的理由，并根据该标准的实施情况总结了气溶胶计径计数法的优点。
Abstract：
Based on the characteristics analysis of the particles counter method and the aerosols counter method, points out the necessity of replacing the former by the latter. Presents that the dust source characteristics and aerosols generator are the core parts in the aerosols counter method, and compares the dust source and the aerosols generator regulated in the standards of ANSI/ASHRAE 52.2-1999 and EN 779:2002. Expounds the reason for adopting the aerosols counter method in the standard of GB/T 14295—2008 of China, and summarizes the advantages of the method based on the implementation of the standard.
