高大空间温度梯度解决方案——以西安赛格商业广场中庭空调及通风设计为例
Temperature gradient solution for tall spaces: Taking air conditioning and ventilation design for atrium of Xi’an SEG Commercial Plaza as an example
摘要：
高大空间冬季供暖时，容易出现明显的烟囱效应，导致热空气上浮，特别是高度较高的中庭，最下面两层与最上面一两层之间的温度梯度较大，体感舒适性差距明显。介绍了西安赛格商业广场项目处理和解决此类问题所采取的措施及手段。根据项目后期实际运行数据，总结了一些心得体会，为该类项目设计提供思路。

Abstract：
When the tall space is heated in winter, it is easy to have obvious chimney extraction, resulting in hot air floating, especially in the high atrium, the temperature gradient between the bottom two layers and the top one or two layers is large, and the gap between somatosensory comfort is obvious. The measures and means taken by the Xi’an SEG Commercial Plaza project to deal with and solve such problems are presented. According to the actual operation data of the project in the later stage, some experiences are summarized, and ideas are provided for the design of such projects.
