密切值法在室内空气品质评价中的应用研究

建立了室内空气品质综合评价密切值法的数学模型,并将其用于某地区4栋大楼室内空气品质的评价,通过与灰色评价法、污染损失率法等方法进行比较.结果表明:密切值法的判定结果等级与污染损失率法的评价结果完全一致,与灰色评价法的评价结果存有差异;从评价结果排序看,密切值法的判定结果与灰色评价法、灰色物元分析法、相似率法、污染损失率法基本一致.说明密切值法用于评价室内空气品质是可行的.而且该评价方法原理简单,计算过程简便,分辨率较高.本研究拓展了密切值法的应用领域,也为室内空气品质评价提供了新的思路和方法.

Application of Osculating Value Method in Evaluation of Indoor Air Quality

The study established a comprehensive evaluation method for indoor air quality based on close value method.It is applied to an area of indoor air quality assessment in four buildings to compare with the grey evaluation method and the pollution loss rate method.The results show that the method of close value judgment has consistent evaluation grades and the rate of pollution loss results, and the evaluation results of grey evaluation method are different;see sorting from the evaluation results, determine the osculating value method and grey evaluation method, grey matter element analysis method, similarity index method, the pollution loss rate method is basically the same.It is feasible to evaluate the indoor air quality by osculating value method.Moreover, the evaluation method is simple, the calculation process is simple and the resolution is high.This study extends the application of osculating value method and provides new ideas and methods for indoor air quality evaluation.
