冬季工况体力活动时人体热舒适实验研究
Experimental study on human thermal comfort under physical activities in winter
摘要：
为了确定体力活动时人体对热环境的温度需求，通过测试和问卷调查的方法进行了冬季实验研究。实验中模拟了2种不同的体力活动。结果表明，在不同环境温度条件下，皮肤温度随代谢量的变化规律有一定差异。通过热感觉投票分析，建立了各活动条件下热感觉与环境温度的关系，并进一步得到了在实验体力活动范围内（1.3～2.8 met）舒适的环境温度区间为14.5～17.5 ℃。
Abstract：
Carries out a study and questionnaire to investigate the people’s thermal requirements when taking physical works and tests the mean skin temperature and metabolic rate in winter. Simulates two different types of physical activities. The results show that the change regulation of mean skin temperature along with metabolic rate is different. Through the analysis on thermal sensation vote, establishes a relationship between thermal sensation and environment temperature under physical activities. Obtains the thermal comfort range from 14.5 to 17.5 ℃ under the experimental physical activities (from 1.3 to 2.8 met）.
