室内空气净化器净化效果评价方法探讨

Exploration of Methods for Testing Effectiveness of Indoor Air Purifying Sets

[目的 ]探索较为科学合理的室内空气净化器净化效果的测定方法 ,使各实验室出具的试验数据具有科学性和可比性。 [方法 ]根据净化器的工作原理对其进行分类 ,对目前流行的几种净化效果检测方法、特点进行分析比较。根据污染物释放平衡式 ,提出了在 3种特定情况下的测定模式 ,并针对这 3种模式 ,就其测定时的影响因素、限定条件进行探讨。 [结果 ]目前流行的几种净化效果检测方法较粗糙 ,不能很好地反映净化器的净化效果。为了使实验操作既简便又不失严谨 ,可将试验过程控制成单纯性挥发模式 ,或其它便于操作处理的模式 ,通过控制其影响因素 ,可获得较为科学的检测数据。 [结论 ]建立正确的测试方法和正确的测试结果表示法是正确评价测试对象的充分必要条件。

[Objective]To explore more scientific and reasonable methods for testing the effectiveness of indoor air purifying sets,so as to obtain scientific and constant experimental data from every laboratories[Methods]The indoor air purifying sets were classified on the basis of their working mechanismsSeveral kinds of current popular methods for testing the purifying effectiveness and their characters were compared each other and analyzedThe influencing factors and limited conditions of 3 determining models under special conditions established on the basis of balance model of pollutants release were explored and studied[Results]Several current popular methods for testing the purifying effectiveness were crude,which couldn't accurately reflact the purifying effectiveness of tested indoor air purifying setsTo ensure the experimental operation simple and strict and to obtain scientific testing data,the experimental process should be controlled and transfered to a model suitable for simple volatile matter or other models easily operated under the control of its influencing factors[Conclusion]The establishments of accurate testing methods and accurate expressions of testing results were the sufficient and essential conditions for accurate evaluation on testing objectives
