项目摘要

Field studies were carried out on air contamination by dust particles from air conditioning systems in four buildings in Tokyo area. We tried to investigate contamination of airborne particle and surface contamination by sedimentary dust in air duct, and considered a matter in all its aspects that caused indoor air pollution. The particulate contamination at surface in air duct is concerned with indoor air pollution, therefore we investigated relations of contaminations with duct surface and supply outlet.Main results obtained were as follows: 1. Time variations of airborne particle concentrations at supply outlet were influenced by the operation of air conditioning system. 2. Specially, maximum concentration was showed at the first one of the day. 3. The test on the opening of the service port door showed most significant in crease of the particulate generation. 4. Size distributions of particle were gained, that are caused by the operation. 5. Particle size of 1- 5mum are worth notice on air contamination from air conditioning systems. 6. For measurement of duct surface contamination, we developed new sumpler that were tested by using optical density(O.D) of particle.

对东京地区四座建筑物空调系统中的尘埃颗粒污染进行了现场研究。本文试图通过对室内空气中颗粒物污染和风管内沉积粉尘的表面污染的研究，全面地探讨引起室内空气污染的一个问题。风管表面颗粒物污染与室内空气污染密切相关，因此本文研究了风管表面颗粒物污染与送风口的关系，主要结果如下：1.送风口空气颗粒物浓度的时间变化受空调系统运行的影响。2.特别是，最大浓度出现在第一天。3.对服务端口门打开的测试显示微粒生成的增加最为显著。4.得到了由操作引起的颗粒尺寸分布。5. 1- 5 μ m的颗粒尺寸对于来自空调系统的空气污染是值得注意的。6.为了测量管道表面污染，我们研制了一种新的采样器，并利用颗粒的光密度（O.D）进行了测试。
