空调开启后的人体生理热反应研究

Physiological thermal response of human body in air conditioning environment

在人工气候室,对室温由29℃分别降至23,25,27℃的3种空调运行环境中室内环境温度和人体6个部位皮肤温度进行了连续测量和主观问卷调查,采用灰色关联度分析方法,研究了空调环境下人体局部皮肤温度、局部热感觉和整体热感觉的变化特性及三者之间的相互关系。结果显示:人体皮肤温度和热感觉呈动态变化,其降低幅度和达到稳定的时间随环境控制温度的降低而增大和延长;控制温度分别为23℃和25℃时局部皮肤温度与局部热感觉显著线性相关,29→27℃工况下线性相关度降低;足背和小腿是空调环境中影响人体整体热感觉的2个关键部位,其影响的重要度随空调环境降温速率的增大而增大。

In an artificial climate room,continuously measures the indoor ambient temperature and the local skin temperatures of six parts of the human bodies in three kinds of air conditioning environments,in which the room temperature decreases from 29℃to 23℃,25℃and 27℃respectively.Meanwhile carries out a subjective questionnaire survey.Studies the variation characteristics of local skin temperature,local thermal sensation and overall thermal sensation in air conditioning environment and their correlations by means of grey correlation analysis.The results show that both skin temperature and thermal sensation vary dynamically,and the decreasing range expands and the stable time prolongs with the decrease of environmental control temperature.There is a significant linear correlation between local skin temperature and local thermal sensation when the control temperature is 23℃and 25℃,respectively,and the linear correlation decreases at 27℃.Finds that the foot and calf significantly contribute to overall thermal sensation in the air conditioning environment compared with other body parts,and the importance of the influence increases with the increase of the cooling rate of the air conditioning environment.
