冬季室内热环境与被褥微气候的匹配

Matching of indoor thermal environment and bed climate in Winter

冬季睡眠状态下,室内热环境与被褥微气候分别对人体头部和被覆躯体的热感觉造成直接影响。为了分析两个热环境的匹配关系以满足睡眠人体的热舒适水平,实验在不同的室内温度下,调节被褥微气候温度,测试了受试者的皮肤温度,并记录了热感觉和热可接受水平。研究结果表明:睡眠状态下,相比于室内热环境,人体热感觉对被褥微气候更敏感;此外,通过分析室内热环境和被褥微气候分别与整体热感觉和整体不满意率的关系,得到了睡眠热环境舒适区间。

The indoor thermal environment and bed climate directly affect the sleeping thermal comfort of human head and the covered body, respectively. In order to analyze the matching relationship between the two thermal environment so as to meet the body＇s sleep thermal comfort level, the skin temperature of the subjects and the thermal sensation and thermal acceptability level of the subjects were recorded with various temperatures of bed climate and indoor temperatures. The results show that the thermal sensation is more sensitive to bed climate than to the indoor thermal environment during sleep. In addition, the comfortable range of thermal sleep environment is obtained through analyzing the relationship between the sleeping thermal environment and the subjective evaluations for partial and overall human body.
