高大空間溫度梯度解決方案——以西安賽格商業廣場中庭空調及通風設計為例
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：
高大空間冬季供暖時，容易出現明顯的煙囪效應，導致熱空氣上浮，特別是高度較高的中庭，最下面兩層與最上面一兩層之間的溫度梯度較大，體感舒適性差距明顯。介紹了西安賽格商業廣場項目處理和解決此類問題所采取的措施及手段。根據項目后期實際運行數據，總結了一些心得體會，為該類項目設計提供思路。

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.
