摘　　要：针对圆柱形剧场冬季空调负荷特点,采用k-εCHEN湍流模型计算了下侧送、上侧回的送回风方式下的剧场气流组织特征。通过改变送风角度,获得不同送风角度下剧院内的温度场、速度场和PMV变化规律。计算结果显示,送风角度为5°时温度和速度分布均匀性最好,舒适度最佳。另外,在最优送风角度的基础上给剧场提供了一种增大送风温度和速度的优化方案,为剧院冬季气流组织的优化设计和舒适性研究提供依据。Based on air conditioning load characteristic in winter of the cylindrical theatre,k- ε CHEN turbulence model was used to calculate airflow characteristics of the theatre in the supply method of underside to send and upper to back. Change rule of temperature field,velocity field and PMV in the theatre was obtained by changing the perspective of air supply. The calculation results show that the temperature and the velocity distribution uniformity are best and the comfort level is optimal when air supply angle is 5°. In addition,a optimization plan was provided by increasing supply air temperature and speed on the basis of the optimal supply air angle,providing basis for air distribution optimization design and comfort research of the theatre in winter.
