夏热冬冷地区夏季风扇对人体热舒适的影响
Impact of fans on human thermal comfort in hot summer and cold winter zone in summer
摘要：
通过问卷调查和现场测试方法对武汉、南京与庐江3个城市的居住建筑室内热环境进行了调研，获得了非供暖空调环境下364套环境参数和人体热反应数据。以中性温度和80%的居民可接受温度范围的形式，量化了使用风扇对人体热舒适的影响程度。结果显示：该地区夏季未使用风扇状态下热中性温度为26.6 ℃，80%的居民可接受温度上限值为29.5 ℃；使用风扇状态下热中性温度为27.3 ℃，80%的居民可接受温度上限值为30.7 ℃。
Abstract：
Studies the indoor thermal environment of residential buildings in Wuhan, Nanjing and Lujiang by the questionnaire survey and field test, and obtains 364 sets of indoor environment and human thermal response data in the natural environment. Evaluates the influence of fans on human thermal comfort through the analysis of neutral temperature and the acceptable temperature upper limit by 80% of the respondents. The results show that the neutral temperature is 26.6 ℃ and the acceptable temperature upper limit by 80% of the respondents is 29.5 ℃ without fans. However, the neutral temperature is 27.3 ℃ and the upper limit is 30.7 ℃ when the fans are used.
