新型空气净化器及其评价方法

Novel air cleaners and their evaluation methods

随着雾霾天气日益频繁,室内空气质量备受关注,传统的室内空气净化器已不能满足室内空气净化的要求,研发新型多功能空气净化器及复合空气净化技术已成为净化器发展的主要方向。本文总结近年来国内外对室内空气净化器的相关研究,综述当前应用最广泛的几种新型室内空气净化器(包括新型吸附材料、低温等离子体、光催化、催化氧化、复合式空气净化器)的研发进展,分析各净化器的优势与不足,总结新型空气净化器的主要评价指标及评价方法,分析其气体污染物、固体颗粒物、微生物污染物进行单一评价的方法,并展望室内空气净化器的研发方向。

More and more frequent haze days increase the concern over indoor air quality. Traditional indoor air cleaners no longer satisfy the requirements of indoor air purification. Thus, development of novel multifunctional air cleaners and comprehensive air purification technologies become a major research direction toward improving indoor air quality and meeting new needs of current market. By summarizing recent researches on indoor air cleaners of both at home and abroad, herein we review several novel indoor air cleaners, including new adsorption materials, non-thermal plasma, photocatalytic, catalytic oxidation and multifunctional air cleaners, and analyze their advantages and disadvantages. The main evaluation indexes and methods of novel air cleaners are also summarized, including the evaluation methods for gas pollutants, solid particles and microbial contaminants. An outlook is also made toward the future research directions of indoor air cleaners.
