分层空调系统在北京丽泽SOHO超高中庭中的应用

Application of Stratified Air Conditioning System in Super High Atrium of Beijing Lize SOHO

丽泽金融商务区是北京市中心城区重要的潜在经济增长点。坐落于此的丽泽SOHO是世界著名建筑大师扎哈·哈迪德在中国的收山遗作。其近200米的中央中庭被誉为世界之最,鱼鳞状幕墙扭曲上升,整体造型极为复杂。超高的中庭由于其空间高大,导致中庭内热环境复杂和可观的空调能耗。因此,有必要借助数值模拟工具与手段分析其中庭的气流组织与热环境,同时用以完善设计。文中对丽泽SOHO中庭分别进行冬季、夏季空调设计工况下热环境分析,并提出相关建议。

Lize Financial and Business District, where Lize SOHO located, is an important potential economic growth point in the downtown area of Beijing. It is the heritage work of Zaha Hadid in China, who is a world-famous architect. Lize SOHO is well known as the world’s highest atrium for nearly 200 meters high. Scale-like curtain wall twists and rises, which make the overall shape extremely complex. Because of its large space, the super-high atrium has complicated thermal environment and consumes considerable energy in air conditioning system. Therefore, it is necessary to use numerical simulation tools to analyze the air distribution and thermal environment, so as to improve the design. In this paper, the thermal environment simulation of Lize SOHO atrium in winter and summer are analyzed, in addition, some suggestions are put forward.
