Exploration of Methods for Testing Effectiveness of Indoor Air Purifying Sets / 环境与健康杂志

ABSTRACT

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