摘要
介绍了国内现行空气过滤器效率的标准检测方法——大气尘计数法,指出了该效率检测方法的优缺点。详细介绍了当前欧、美等国家空气过滤器效率的标准检测方法—气溶胶粒径计数法,并从试验用气溶胶、检测仪器和效率标识三个方面对欧、美的效率检测方法进行了详细的分析比较。列出了气溶胶粒径计数法较大气尘计数法的优越性,进而提出了用气溶胶粒径计数法来检测空气过滤器效率的观点。并详细说明了用气溶胶粒径计数法检测空气过滤器效率的操作方法。
The method of air filters efficiency test in China （particles counter method） is introduced, and its advantage and disadvantage are pointed out. The current Europe and the USA air filters efficiency methods （aerosol size counter method） are also discussed. The Europe and the USA test methods are compared and analyzed in detail from three aspects which are experimental aerosol, particle counter and expression of efficiency. The superiority of aerosol size counter method is put forwards. The operation method of aerosol size counter method to test filter efficiency is also set forth.
