我国湿热地区人群基础热舒适反应研究(1):实验方法与结果
Human thermal comfort research in hot-humid area of China (1): experimental methods and results
摘要:
采用经典热舒适研究方法,于2008年夏季对我国湿热地区典型人群受试者作了气候室实验,在凉-暖范围内6个不同温湿度组合的工况下进行了问卷投票和生理指标测试。结果显示,受试者的热中性温度为26.9 ℃(修正温度);受试者夏季偏爱稍凉的热感觉(-0.2);潮湿感中性对应的水蒸气分压力约为3 500 Pa;热中性对应的平均皮肤温度为33.2 ℃;平均皮肤温度与皮肤湿润度是预测热感觉与热舒适的重要参数;心率与热感觉存在线性关系,血压在偏凉环境下与热感觉呈线性关系,在偏暖环境下变化不大。
Abstract:
Based on the classic thermal comfort research methodology, performs a climate chamber experiment with 30 typical subjects in the hot-humid area of China in the summer of 2008, and questionnaire and physiological responses are collected under six different temperature and humidity combination conditions in the range of cool to warm. The results show that the neutral temperature is 26.9 ℃ in modified temperature; the preferred sensation is -0.2 in summer; the partial pressure of water vapor is about 3 500 Pa when the humid sensation is neutral; the mean skin temperature is 33.2 ℃ corresponding neutral thermal sensation; the mean skin temperature and skin wetness degree are important in predicting thermal sensation and thermal comfort; there is a linear relation between the heart rate and thermal comfort, and between the blood pressure and thermal comfort in cooler environment but the blood pressure varies not obviously with thermal sensation in warmer environment.
