国家会展中心（上海）超高大展厅空调通风设计
Air conditioning ventilation system design for super high and large space exhibition hall in National Exhibition and Convention Center（Shanghai）
摘要：
介绍了会展建筑的特点，对展厅空调送风方式做了调研并对调研结果进行了分析。给出了展厅的设计参数，对全部侧送风、侧送风+风口与桁架齐平上送风、侧送风+风口高度降低10 m上送风、全部上送风4种典型送风方式进行了CFD数值模拟计算，结合空调效果、能耗差异等因素，采用全部上送风方式及自动调节气流流型风口。冬季空调测试结果表明，场馆内温度满足设计要求。
Abstract：
Presents the architectural features about exhibition and convention building. Through researching air supply modes of air conditioning system for exhibition hall, analyses their results and provides the design parameters. Calculates CFD numerical simulation for four kinds of typical air supply modes, including the all side air supply, side and upper air supply with outlet at the same height with structure truss, side and upper air supply with outlet 10 meters lower than structure truss and all upper air supply. Combined with the factors of air conditioning effect, energy consumption difference and others, adopts all upper air supply mode and the automatic regulating airflow outlet. The testing results in winter show that the indoor temperature can meet the design requirements.
