【摘要】 要想提高中国居民的整体室内环境健康的素质,真正改善人们的家居环境,开发一套方便可行、益于推广、速度快、低成本的“居室室内甲醛浓度的预测系统”就成为了当务之急。这正是进行本课题研究的根本动机。但是人们对此问题没有产生足够的重视,只是等到已经修建完成之后,亡羊捕牢,这样又花费了大量的金钱和时间,效果又不明显,所以如果能够开展在设计协调中对室内空气品质的预测,对各方都是有利的。本文的研究思路为:重庆地区室内装修环境污染调查分析—对影响室内主要污染物甲醛的浓度变化的因素进行分析—利用统计学方法建立室内主要污染物甲醛浓度的数学预测模型—整合通风模型与甲醛预测模型,构建室内甲醛浓度预测系统内核—利用C++ Builder软件开发研究室内甲醛浓度预测系统软件—对软件进行评价提出不足之处和改进意见。本文监测实际装修工程施工期间和竣工后室内甲醛浓度的变化情况,对40户装修住宅室内空气中污染物浓度的检测结果显示,甲醛的超标率和超标倍数最明显,可见,甲醛是重庆城市住宅室内空气中最主要的污染物。而甲醛的长期的主要污染源又是因为板材的释放,因为其他污染源产生的危害在短期内可以消除。通过对新装修住宅,进行装修全过程中室内甲醛浓度的跟踪监测,对影响甲醛浓度变化的外部原因如温湿度变化、通风等因素进行实验分析。通过对大量的采集的数据的整合及结合前人的研究,作者利用统计学方法得出重庆市甲醛浓度预测模型: C = 0.527 Q (0.102T-1.103)(0.015D+0.175)/1.218+1.071N/G式中C——室内空气质量甲醛浓度,mg/m3 T——室内温度,℃D——室内空气相对湿度,% Q——板材单位面积释甲醛率,根据板材分类等级可知N——房间每小时换气率,0.1～1.0次/h G——单位体积房间所使用板材的表面积板材表面积S/房间容积V)通过将复杂的通风模型进行简化,将甲醛浓度预测模型与简化通风模型进行整合,建立了以通风模型为最底层,室内甲醛的模型为第二层,室内空气品质等级评价方法、个人浓度暴露模型为上一层次的客观评价的居室室内空气品质的评价系统理论。更多还原

【Abstract】 In order to lift the entire interior environment health of Chinese inhabitant quality and improve the home environment truly,opening up a suit convenient feasible,easily spreading, velocity quickly,low cost of " air quality of room interior calculation evaluation system " becomes straightforward business emergency . This is being carrying on a fundamental intention of subject study .Yet people do not take this problem seriously enough. Just seeze the prison when the sheep running away, Costing so much money and time , deserving much more unobvious effect .so if we can adjust the interior air quality in the middle of design harmonization,it’s benificial to each side.The original research thinking is following: Pollution of the interior environment diagnosis is fitted up in the Chongqing area—The element which effect the main contaminant formaldehyde concentration is analysed—utilizing the statistics means to establish mathematics forecasting model of the main interior contaminant formaldehyde—That the conformity ventilation pattern and the formaldehyde forecasting model constructs the interior systematic crux of a matter of formaldehyde concentration calculation—Utilizing inner place the C++ software to develop the room formaldehyde concentration forecasting system software—Evaluating the shortcoming and the modification idea to software.According to the conformity that adjust the greats quantity data which collected. Writer utilizes the statistics means to obtain the formaldehyde concentration forecasting model: C=0.527 (0.102-1.103)(0.015+0.175)/1.218+1.071N/GC—Interior air quality formaldehyde concentration, mg/m3 T—Interior temperature,℃D—Interior air relative humidity, % Q—Elucidateed the formaldehyde rate of the plate unit area, on the basis of the plate classification rank knowably N—Room breath rate of per hour, 0.1 - 1.0 /hs G—Unit bulk room use plate surface area Plate surface area /Room volumeBy means of simplifying the complex ventilation pattern, Carrying on the conformity by the formaldehyde concentration forecasting model against the更多还原
