Abstract
研究共邀請140名受試者在環境實驗室進行坐姿條件下的熱舒適調查,受試者均身著典型夏季服裝。調查過程中,室內溫度控制在25至30℃,受試者身體附近的空氣流速控制在0.5至3.0m·s-1,室內的相對濕度控制在50%左右。調查中,要求受試者按照ASHRAE七級標準對熱感覺做出評價。通過對結果進行多重回歸統計分析,得到年齡介於19至25歲之間的香港居民,他們的熱感覺受室內空氣溫度和空氣流速的影響。研究還進一步得到當室內空氣溫度在25至30℃之間變化時,不同溫度條件下對應的滿足熱舒適的空氣流速範圍。同時,調查中比較了不同的空氣溫度和風速的組合條件下,熱感覺投票值和傳統的預測平均投票值(PMV)之間的差異。
In this study, 140 human subjects wearing typical summer clothing were invited to an environmental chamber to conduct a thermal comfort survey in sedentary position. The studying air temperatures were in the range of 25 to 30 ℃, air speeds 0.5 to 3 m·s-1 at 50% RH. Their thermal sensations were collected by using the ASHRAE 7-point scale. Multiple regression analysis was carried out to study the effect of both indoor air temperature and air speed to the thermal sensation of Hong Kong people in the age group of 19 to 25. The difference in thermal sensation between male and female subjects was also studied. A comfort zone for different air speeds in the temperature range of 25 to 30 ℃ was developed. The results of the thermal sensation of different combinations of air temperature and air speed were compared with the predicted mean vote (PMV).
