【摘要】 为了进一步明确湿热地区不同室外空间夏季的热环境设计要求,提高使用者的热舒适水平,以广州为例,通过热环境测试和热舒适调研,获得了6处不同室外空间的热环境水平和主观热舒适评价特点。统计结果显示:开阔的广场空间接受的太阳辐射较多,居民偏热投票最多,热感觉投票值和太阳辐射量相关性最强,相关系数达0.718以上,广场空间进一步增加湿度的投票比其它空间多;遮阴区域的架空层和东西街居民偏热投票最少,热感觉投票值与空气温度或相对湿度相关性最强;小区活动场地内的热感觉投票值与各热环境参数的相关性均较低。研究推荐遮阳和增湿作为广场空间热环境改善的最主要方法,架空层是6处室外空间中最为适宜的活动场地。更多还原

【Abstract】 In order to further clarify the design requirements of thermal environment in different outdoor spaces in hot and humid areas in summer and improve the thermal comfort of users, the characteristics of thermal environment and subjective thermal comfort evaluation of six different outdoor spaces in Guangzhou were obtained through thermal environment test and thermal comfort investigation. According to the statistical results, the open square space receives more solar radiation and most thermal sensation votes from residents, so thermal sensation votes are most correlated with solar radiation, with the correlation coefficient above 0.718, and the open square space gets more humidity votes than other spaces. The stilt floor and the east-west street in the shade area receive fewest thermal sensation votes, so the thermal sensation votes are most correlated with temperature or relative humidity. The thermal sensation votes of activity space are less correlated with thermal environment parameters. Shading and humidification are recommended as the main methods to improve the thermal environment of square space, and the stilt floor is most suitable for activities in the six outdoor spaces.更多还原
