我国湿热地区人群基础热舒适反应研究(3):冬夏对比分析

Human thermal comfort research in hot-humid area of China(3)—Comparison between winter and summer

沿用经典热舒适研究方法,对我国湿热地区自然通风环境受试者分别进行夏季和冬季气候室实验,并对其心理反应与生理反应作冬夏季对比,得到其热反应的季节性变化特征为:与夏季相比,冬季的热感觉保持不变,但热舒适度与可接受度在低温环境显著降低,而在高温环境显著升高;心率显著增加,皮肤温度有所升高,在高温环境下的皮肤湿润度有所降低。季节性变化特征为湿热地区人群心理适应与生理习服提供了重要证据。

Using the classic thermal comfort research methodology,performs a climate chamber experiment to study the examinees＇ responses in naturally ventilated buildings in hot-humid area of China both in summer and winter.Makes psychological and physiological response comparison between the two seasons.The obtained seasonal variations are that thermal sensation in winter keeps the same as in summer,but thermal comfort and acceptability become poor under cool environments and improve under warm environments.Besides,the heart rate and skin temperature are higher in winter than in summer,and the skin wetness is lower under warm environments.The variations provide important evidences for psychological adaptation and physiological acclimatization of people in hot-humid regions.
