我国湿热地区自然通风建筑夏季热舒适研究——以广州为例
Thermal comfort in naturally ventilated buildings in hot-humid area of China in summer: an example study of Guangzhou
摘要：
2008年夏季对广州某高校学生在自然通风建筑中进行了501人次的热舒适现场调查，调查内容包括热感觉、热舒适度、热可接受度及潮湿感，并对相应的室内干球温度、相对湿度、黑球温度和风速等热环境参数进行了测试记录。通过对数据的整理分析发现，自然通风建筑的夏季室内温湿度均高于ASHRAE标准的舒适区域，但人们对该环境有较好的适应性。调查结果表明，我国湿热地区自然通风建筑的热中性温度为28.1 ℃（ET*=29.3 ℃），可接受的热环境温度的上限为29.7 ℃（ET*=30.9 ℃），相对湿度上限为78%。
Abstract：
Presents a 501 person-time field survey of thermal comfort in naturally ventilated buildings of an university in Guangzhou in summer 2008, during which the data of human thermal sensation, thermal comfort, thermal acceptability and humidity perception are collected and the indoor thermal parameters including dry-bulb temperature, relative humidity, black globe temperature and air velocity are recorded. The results reveal that although the thermal conditions are out of the ASHRAE comfort zone, people can adapt themselves to the local environment. Obtains the neutral temperature 28.1 ℃ (ET*=29.3 ℃) and the upper limit of the acceptable temperature 29.7 ℃(ET*=30.9 ℃) and the upper limit of the acceptable relative humidity 78%.
