影剧院建筑内置换通风方式的优化设计

为了更好地研究置换通风方式在影剧院建筑内的应用，采用CFD方法，对影剧院内采用地面附近侧送风形式的置换通风进行了数值模拟．计算结果显示，CFD技术能够较好地应用在影剧院建筑内置换通风方式的优化设计方面，并能够得出比较合理的设计参数．在原有设计的基础上，通过合理地调整风口位置及送风参数获得了较好的通风效果．把CFD技术引入到对影剧院建筑内空调系统气流组织方案的设计中，有利于地面附近侧送风方式的应用，也有助于节能措施的推广与实施．

Optimizing Design of Displacement Ventilation in Cinema

In order to research the displacement air conditioning in cinem conditioning system with wall diffuser in cinema with the CFD. According a, the writer simulates the displacement air to the result of the computing, we can find that if we adjust the position of the openings and parameter of air-inlet in reason. It is useful to make good use of displacement air conditioning system with wall diffuser and extend the saving energy methods by using the CFD technology in designing the air condition system in cinema.
