室内照明环境对可感空气品质评价影响的实验研究
Experimental research on influence of indoor luminous environment on perceived air quality evaluation
摘要：
以问卷方式调查了受试者在各种室内环境条件下(110 lx和220 lx 2种照度水平、14 m3/(人·h)和48 m3/(人·h) 2种新风量、室内温度14～25.7 ℃、室内相对湿度50%±3%)对可感空气品质的主观评价。结果显示：在尽量排除热感觉对室内空气品质主观评价影响的情况下，室内照度水平对空气沉闷感和空气接受度评价指标的影响较明显，对异味感和空气新鲜感评价指标的影响不明显；220 lx照度下受试者对空气沉闷感和空气接受度的评价结果优于110 lx照度情况；110 lx照度下空气沉闷感和空气接受度评价结果随室内温度的变化率大于220 lx照度情况；室内温度越低，照度差异引起的空气沉闷感和空气接受度差异越小。
Abstract：
Investigates the subjective evaluation on perceived air quality under different indoor environment conditions of two illumination (110 lx and 220 lx), two outdoor air rates (14 m3/(person·h) and 48 m3/(person·h)), indoor temperature of 14 to 25.7 ℃ and indoor relative humidity of 50%±3% by questionnaires. The results show that the indoor illumination can influence obviously the evaluation on air depressing perception and acceptability and has ignorable influence on the evaluation on smell and air fresh perception under the condition that the influence of thermal sensation on the subjective evaluation on indoor air quality is not included. The evaluations on air depressing perception and acceptability are better in the illumination 220 lx than those in the illumination 110 lx. The change rates of air depressing perception and acceptability with temperature change in the illumination 110 lx are greater than those in the illumination 220 lx.The lower the indoor temperature is, the smaller the differences of the air depressing perception and acceptability caused by illumination difference are.
