摘要
通过改变室内环境条件,使用主观问卷填写和生理参数测量相结合的方法,研究3种温度水平下室内空气质量和照明色温对青年受试者环境感知和病态建筑综合症症状的综合作用影响。16名身体健康的青年受试者暴露于12种不同工况下,环境变量包括室内空气温度、室内空气质量和照明色温。结果显示,照明色温对受试者的热感觉投票和空气质量评价有明显影响。冷光使热感觉投票降低,空气质量评价提升。在22℃和28℃时,照明色温对感知空气质量投票有显著影响(p<0.05)。在3个温度水平下,室内空气质量和照明色温的交互作用均对脉率的变化影响显著(p<0.05)。仅在28℃时,发现照明色温对血氧饱和度产生显著影响(p<0.05)。受试者出现病态建筑综合症症状的比例与室内空气温度呈正相关。在18℃时,眼部不适症状的出现与室内空气质量和照明色温的交互作用显著相关(p<0.001)。
This article investigated the comprehensive effects of indoor air quality and illumination color temperature on occupant environmental perception and sick building syndrome symptoms under three temperature levels(18℃,22℃,and 28℃).We collected subjects'responses for indoor environmental quality and sick building syndrome symptoms by a combination of subjective questionnaires and physiological parameter measurements.16 subjects(8 males and 8 females)were exposed to 12 different conditions.Environmental variables included indoor air temperature,indoor air quality(PM_(2.5) concentration),and illumination color temperature.This work created two different air quality environments by introducing or not introducing four old carpets and created warm light(3000 K)and cool light(6000 K)by LED lights with adjustable color temperatures.The results show that environmental perception votes and the percentage of people with sick building syndrome symptoms all change under the combined influence of indoor air quality and illumination color temperature.When the air temperatures are 18℃and 22℃,the cool light(6000 K)reduces the thermal sensation values and improves the air quality evaluation.At 22℃and 28℃,illumination color temperature significantly improves perceived air quality(p<0.05).Under the three temperature levels,the interaction between indoor air quality and illumination color temperature has a significant influence on the change of pulse rate(p<0.05).Only at 28℃,it is found that illumination color temperature has a significant influence on blood oxygen saturation(p<0.05).As the air temperature rises,the proportion of subjects with sick building syndrome symptoms increases significantly.At the temperature of 18℃,the symptom of eye discomfort is significantly correlated with the interaction between indoor air quality and illumination color temperature(p<0.001).Therefore,the combined effect of indoor air quality and illumination color temperature should be considered in the indoor environment to optimize th
