存在于所有空间的电场都与空气中的电荷、粒子（大部分是亚微米）以及被吸收和吸附的气体相互作用。这些相互作用，而不是气流，在很大程度上决定了污染物在人、动物、墙壁和房间内物体上的移动和沉积。空气中的许多亚微米粒子，随着年龄的增长，会发生碰撞，形成更大的粒子。这种自然过程称为凝固。挥发性有机化合物（VOCs）和加臭剂往往会吸附在颗粒上。因此，挥发性有机化合物最终被排放到动物和人身上或被困在过滤器中的地方，也会受到室内正常电场的影响。物理理论、实验室数据和现场研究表明，加速混凝可以提高过滤器去除污染物的效果。总结了与动物设施空气质量控制相关的加速凝固在控制颗粒物、气味和气体污染方面的有效性的公开数据。 关键词:控制装置、建筑物、空气质量、室内、实验动物住房、有机化合物、甲醛、氨、颗粒物、气溶胶、气味、性能、空气清洁、过滤器、污染物、物理、实验、内容、电磁学引用:研讨会，ASHRAE Trans。1994年，第100卷，第2部分

The electrical fields that exist in all spaces interact with airborne charges, particles (most of which are submicron), and absorbed and adsorbed gases. These interactions, not air currents, in large part determine the movement and deposition of contaminants in and on people, animals, walls, and objects in a room. Many of the submicron particles in the air, as they age, collide and form larger particles. This natural process is called coagulation. Volatile organic compounds (VOCs) and odorants tend to absorb and adsorb onto particles. Thus, where VOCs end up, plated-out in and on animals and people or trapped in the filters, is also influenced by the normal electrical fields in a room. Physics theory, laboratory data, and field studies indicate that the effectiveness of filters in removing contaminants can be enhanced by accelerating coagulation. Summarises published data on the effectiveness of accelerating coagulation in controlling particle, odour, and gaseous contamination as it relates to air quality control in animal facilities.KEYWORDS: controls, buildings, air quality, indoor, laboratory animal housing, organic compounds, formaldehyde, ammonia, particles, aerosols, odour, performance, air cleaning, filters, contaminants, physics, experiment, content, electromagnetism
