项目摘要

The aim of this research is to clear the long term chemical pollution in houses considering the peoples behaviors in houses as operating windows, operating heating systems. At first, a measurement instrument to record the width of openings is made and the performances were investigated using houses. And the instrument was enough useful to use in general houses with the dwellers. The questioner survey was made to know the data of houses and their living style.The changes of opening width of windows were measured in 13 houses. The indoor and outdoor temperatures, these humilities and the concentrations of formaldehyde and carbon dioxide in rooms were also measured in three houses. These measurements showed that the people dos not open windows even in the mild seasons because of thief life style and the condition of the surroundings. These results showed that the risk of the indoor air pollution increases in the middle seasons.A simulation program : Fresh 2006 was improved to show the annual change of the indoor concentrations and the temperatures considering the habits of opening windows. And the leakage networks which were measured using structure models were used and the infiltration rates from the concealed pollution sources for example, the chemical compound to terminate termites to indoor spaces were calculated using the program.The results showed the followings. The infiltration from the concealed spaces was one of the important factors to make the indoor air quality. In the case of exhaust ventilation, this factor became more important. The concentrations of most pollutants become low in summer and become high again in autumn. But in the case formaldehyde, the concentration does not become high in autumn because the ability of the emission form building materials as plywood was reduced by opening windows in summer.

这项研究的目的是清除房屋中的长期化学污染，考虑到房屋中的人民行为是操作窗户，操作供暖系统。首先，制作了一个测量工具，以记录开口的宽度，并使用房屋研究了表演。该仪器足以在与居民的一般房屋中使用。进行了发问者的调查是为了了解房屋的数据及其生活方式。在13个房屋中测量了窗户的开口宽度的变化。在三座房屋中，还测量了室内和室外温度，这些耗时以及甲醛和二氧化碳的浓度。这些测量表明，由于小偷的生活方式和周围环境的状况，人们即使在温和的季节中也没有打开窗户。这些结果表明，中季中室内空气污染的风险增加了。一个模拟计划：新鲜的2006年有改善，以显示室内浓度的年度变化以及考虑到打开窗户的习惯的温度。并使用了使用结构模型测量的泄漏网络，并使用该程序计算了隐藏污染源的浸润速率，例如，使用该程序计算了终止白蚁到室内空间的化合物。结果显示了以下内容。隐藏空间的渗透是使室内空气质量的重要因素之一。在排气通风的情况下，这个因素变得越来越重要。大多数污染物的浓度在夏季变得较低，并在秋季再次变得很高。但是在这种情况下，甲醛，秋季的浓度不会变得很高，因为由于夏季打开窗户，降低了排放形式的建筑材料的能力。
