某剧院观众厅空调系统气流组织研究

Research on air distribution of air conditioning systems in auditorium of a theater

针对剧院建筑观众厅空调系统气流组织设计的难点,以数值模拟为手段,对基准方案下的夏季设计工况进行了气流组织分析。在此基础上通过调整送风温度、前后排送风量分配、楼座回风口位置三大影响因素,寻找气流组织的优化与改善方向,进而得到优化方案下的观众厅温度场与速度场分布,为项目设计提供决策依据。

In view of the air distribution design difficulties of the air conditioning system in the auditorium of the theater building,the air distribution under the summer design condition of the benchmark scheme is analysed by means of numerical simulation.On this basis,the optimization and improvement direction of the air distribution is found by adjusting the three influencing factors including the supply air temperature,the distribution of the supply air volume of the front and rear seats,and the position of the return air outlet.Then the distribution of temperature field and velocity field in the auditorium under the optimization scheme is obtained,which provides a scientific decision-making basis for the project design.
