室内热环境和新风量对室内可感空气品质主观评价的影响

Impact of Indoor Thermal Environment and Fresh Air Rate on Subjective Evaluation of Perceivable Indoor Air Quality

本研究在14 m^3/(h·人)和48 m^3/(h·人)的新风量条件,室内气温14~30.4℃、相对湿度38%~77%、风速<0.15 m/s的热环境情况下,在实验室内对可感空气品质评价进行了调查研究,旨在研究在常见的室内热环境和新风量范围内,空气温度、焓值及相对湿度对空气品质主观评价的影响规律。分析结果得到了室内热环境参数对4项可感空气品质的评价指标的作用规律,以及4项评价指标之间的相关性情况等结论。

The study was carried out in the conditions of fresh air rate of 14 m^3/h per person and 48 m^3/h per person,indoor temperature in the range of 14 - 30. 4 ℃,38% - 77% relative humidity and wind speed 0. 15 m/s. The aim is to study the impact of indoor temperature on the evaluation of perceivable indoor air quality in an indoor common and wide temperature range. There are four subjective evaluation indexes of perceived air quality in the paper,i. e. odor perception,air fresh perception,air depressing perception and acceptability of air. Through analysis of the test data and the statistics,the results indicated that the evaluation of fresh air perception,acceptability of air and air depressing perception are all improved with the decreases of indoor temperature in the above situation.
