Experimental research on influence of indoor luminous environment on perceived air quality evaluation

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.
