基于韦伯-费希纳定律的住宅室内环境质量评价方法

An evaluation approach of indoor environment quality in residential buildings based on Weber-Fischna law

将PMV分级方法与韦伯-费希纳定律结合起来,围绕室内环境主要影响参数温度、噪声、二氧化碳、甲醛以及照度5个方面对室内环境质量进行了评价方法研究。基于各个环境因素的单独评价模型,利用线性合成模型建立了室内环境质量综合评价方法。该方法的评价预测结果完全基于房间的实测环境数据,能够对房间的环境质量进行实时、长期而大范围的评价,可以弥补以往问卷调查投票方法的短暂性和片面性。利用从5个家庭中采集的数据对该方法进行了验证,该方法的计算结果与室内人员的反馈情况较为吻合,证明该方法合理可行。

By combining the PMV grading method with the Weber-Fischna law,the research was carried out on the evaluation of indoor environment quality（ IEQ） with 5 main parameters that impact the indoor environment,including temperature,noise,carbon dioxide,formaldehyde and luminance. Then,based on the evaluation models from each individual parameter,a new comprehensive evaluation approach of IEQ was proposed by the linear synthetic model. This approach predicted occupants＇ evaluation for the IEQ completely based on collected indoor environmental parameters. So it could obtain real-time evaluation results in long-term and large scale,which was supplement for the field questionnaire survey. The approach was validated by the data collected from 5 families. The results predicted from this approach agreed well with the feedback from the occupants.
