高密度人流开放空间降温与遮阳设计的研究

RESEARCH ON COOLING AND SUNSHADE DESIGNS FOR OPEN SPACE WITH HIGH-DENSITY PEDESTRIAN STREAM

现代城市开放空间中,高密度的人流和极端炎热的天气往往造成其使用舒适度降低,有必要通过场地降温设计改善城市高密度人流开放空间的环境舒适度。以世博会场地这一典型的高密度人流开放空间为例,研究场地降温与遮阳设计。研究基于对人体舒适度模型的分析,通过对影响人体舒适度的4个因子的比较,采用低压雾喷降温设备,并结合场地遮阳设施进行合理的布局和设计,可有效改善场地使用人群的体感舒适度,达到高密度人流开放空间的人性化使用。

In modern city, the comfort of using open space can be reduced by high-density people and extreme hot weather. Therefore, it is necessary to improve the environmental comfort of open space with high- density people. Our attention is paid to the cooling and sunshade design of EXPO site which is a very typical example in the open space with high-density people. Basing on the model of human comfort, the research analyses and compares the four factors which can impact human comfort, and then chooses low-pressure casing spray, finally makes right layout considering the sunshade equipments in the ground to improve human comfort and achieve the humanized use of open space with high-density people.
