基于相对差异函数的室内空气品质的评价

Application of relative difference function for indoor air quality

为了科学评价室内空气质量的品质,选取了七种主要污染物作为评价指标,建立了室内空气质量评价的指标体系及评价等级标准。在引入相对差异函数的基础上,建立了单指标对各参考等级的隶属度,参照已经发表文献中颗粒物、CO2、CO、甲醛、NO2、SO2、细菌总数的权重值的基础上,变换模型中参数的数值,计算各评价因子特征值的均值和比较数值的大小比较,最终确定各评价因子的排列顺序。将基于相对差异函数的评价模型用于室内控制品质的评价实例进行检验,验证了该模型准确可行。该评价方法用于室内空气品质的评价具有较高的灵敏度和区分度。

In order to evaluate the quality of indoor air quality scientifically,Seven main influencing the indoor air quality were cho-sen. The index system of indoor air quality evaluation and its index scores are set up.Based on the introduction of the relative differ-ence function,the relative difference function is used to get each reference level .Reference has been published in the literature about the weight of particulates ,CO2,CO,IP,NO2 ,SO2 ,total count of bacteria which were 0.25,0.25,0.0625,0.25,0.0625,0.0625,0.0625respec- tively. The evaluation factors were determined finally by changing the parameters of the model and comparison of the mean value. The indoor air quality evaluation model based on relative difference function was used for the evaluations of indoor air quality cases and the results shows that the model is feasible and accurate, the evaluation method was applied to the evaluation on indoor air quality with higher sensitivity and region division.
