室内空气净化器测定方法探讨

选择一处目前较为流行的、以高压静电及纤维滤料除尘、碳纤维板吸附为净化原理的室内空气净化器为测试对象，测定其对ＩＰ、尼古丁空气耗氧量、甲醛、ＳＯ２、ＮＯＸ、ＮＨ３、ＣＯ、ＣＯ２和细菌总数十项指标的去除效率。同时测定了不开净化器时各项指标的自然衰减率，还测定了不同本度污染浓度对去除率的影响，对该净化器的净化效果作了客观的评价。并对室内空气净化器测试方法中有关影响因素进行了有益的探讨。

The Study on the Method of Testing the Room Air Cleaners

A room air cleaner,which cleaning system for particles and gases consists of electrostatic precipitator,fiber filter and activated carbon,has been tested in a closed room of 16m3,We monitored the decay rates of ten indexes such as inhalable Particles, nicotine,air oxygen demand, formaldehyde,sulfury dioxide,nitrogen dioxide,ammonia,carbon monoxide,carbon dioxide, total bacteria both with a room air cleaner and without any cleaner.and observed the effect of different initial concentration for the decay rates.The cleaner's purificatory ability was evaluated objectively and the identification conditions on the efficiency detaction of the air cleaners were discussed.
