摘要
本文采用实验方法研究了负离子对某食堂环境的改善效果。着重研究了负离子的区域分布规律、负离子对可吸入颗粒物的改善效果和对各个粒径范围颗粒物的凝并、沉降效果。分析了负离子、滞留密度和颗粒物浓度之间的关系。揭示了负离子在人流密度大的开放性场所应用的可行性。
The effect of negative ion on indoor air quality of a restaurant was investigated by experimental method, especially focusing on the distribution of negative ion in the dinning hall,the effect of PMIO and the particle with different size.After analyzed the relations among negative ion concentration,stranded density and particle concentration, the feasibility of negative ion applied in a place with a large stranded density was revealed.
