重庆地区办公场景室内自然环境下人体热反应研究

Study on Human Thermal Response under Natural Indoor Office Environment in Chongqing

为了研究重庆地区冬季室内自然环境下人体热反应,以在校大学生为受试人群,在实验室采用现场热环境测量及主观问卷调查相结合的方式,进行了身体不同部位在不同温度状态下的热反应研究。研究分析了冬季自然低温环境下,人体整体主观热反应差异;结合数理统计的方法,分析了各温度区间下受试者的热感觉;探讨得到了自然低温环境的可接受温度区间。进一步探究了身体不同部位热感觉的差异性,对比分析不同部位热感觉的显著性区别,得到了身体各部位的冷感分布情况,以及整体热感觉的代表部位。研究得到了冬季自然环境下的人员可接受温度和不同身体部位热感觉分布,定量明确了自然低温环境下人体的热反应规律,为进一步合理确定自然室温环境评价和环境高效营造提供基础依据。

To study the thermal response of the human body under the natural indoor environment in winter in Chongqing,this paper,with university students as the subjects,conducted research work on the thermal response of different body parts under different temperature states using a combination of on-site thermal environment measurement and subjective questionnaire survey in the laboratory.The overall subjective thermal responses of people in the natural cool environment in winter were analyzed,and the thermal sensation of the subjects in each temperature range was also analyzed using mathematical and statistical methods.Based on these,the acceptable temperature range in the natural cool environment was identified.This paper further explored the variability of thermal sensation in different body parts,and obtained the distribution of cold sensation in each body part and the representative parts of overall thermal sensation by comparing and analyzing the differences in thermal sensation in local body parts.The acceptable temperature of human body and the distribution of thermal sensation in different body parts under natural cool environment in winter identified can provide some reference for further rational determination of natural indoor environment evaluation and efficient environment creation.
