寒冷地区非空调建筑内季节对人体局部皮肤温度及热感觉影响

Effects of Seasons on Local Skin Temperature and Thermal Sensation in Non-airconditioned Buildings in Cold Areas

为了探究人体局部皮肤温度与热感觉的季节性变化规律,对四个季节中局部皮肤温度与热感觉进行了实验研究。结果表明:背部、胸口等核心部位在各季节中变化较小,维持在稳定的温度范围内。头部、手掌、小腿、脚踝等末端部位会随着季节变化更加明显。春季上肢部位以及头部对热感觉的影响最大;夏季脚踝和躯干部位对热感觉的影响最大;秋季四肢部位对热感觉的影响最大;冬季四肢末端部位对热感觉的影响最大。可针对不同部位在各个季节中的敏感性提出提升舒适感的方法。

In order to explore the seasonal variation of local skin temperature and thermal sensation in the human body,the local skin temperature and thermal sensation in the four seasons were experimentally studied.The results showed that the core parts such as the back and chest changed less in each season and remained within a stable temperature range.The ends,such as the head,palms,calves,and ankles,change more pronounced with the seasons.The upper extremities and head have the greatest effect on thermal sensation in spring,the ankles and trunk have the greatest effect on thermal sensation in summer,the extremities have the greatest effect on thermal sensation in autumn,and the terminal parts of the extremities have the greatest effect on thermal sensation in winter.Ways to improve comfort can be proposed for the sensitivity of different parts in each season.
