摘要

由于我们大约80%的时间是在室内度过的，改善室内空气质量对于减少呼吸系统疾病的传播和影响以及由颗粒污染引起的其他健康问题是必要的。目前，在许多国家，清洁室内空气的主要方法是在再循环空气系统中使用更好、等级更高的过滤器或增加室外空气的通风。对这些久经考验的方法进行补充的一种方法是实施电离。我们使用双极电离器来测试不同粒径的过滤器在电离和不电离的情况下的去除效率。经过校准的香烟被用来在一个28立方米的房间里产生烟雾，房间里有一个循环空气处理系统。结果表明，对于穿透性最强的粒径(100 ~ 500 nm)，离子处理的去除率提高了275%。我们得出结论，电离大大提高了室内环境中细颗粒和超细颗粒的过滤器去除效率。

Effects of Ionization on the Filtration of Fine and Ultrafine Particles in Indoor Air

As we spend approximately 80% of our time indoors, improving indoor air quality is necessary to lessen the spread and impacts of respiratory diseases and other health issues caused by particle pollution. Currently, in many countries, the primary method of cleaning indoor air is by using better, higher-grade filters in a recirculating air system or increasing ventilation with outdoor air. One way to supplement these time-tested approaches is by implementing ionization. We used a bipolar ionizer to test the removal efficiency of filters on different particle sizes with and without ionization. Calibrated cigarettes were used to generate smoke into a 28-cubic-meter chamber with a recirculating air handling system. It was found that ionization had a 275% increase in the removal efficiency of the most penetrating particle sizes (100-500 nm). We conclude that ionization drastically improves the filter removal efficiency of fine and ultrafine particles in indoor environments.

期刊介绍： The quality of the environment within buildings is a topic of major importance for public health. Indoor Air provides a location for reporting original research results in the broad area defined by the indoor environment of non-industrial buildings. An international journal with multidisciplinary content, Indoor Air publishes papers reflecting the broad categories of interest in this field: health effects; thermal comfort; monitoring and modelling; source characterization; ventilation and other environmental control techniques. The research results present the basic information to allow designers, building owners, and operators to provide a healthy and comfortable environment for building occupants, as well as giving medical practitioners information on how to deal with illnesses related to the indoor environment.
