【摘要】 随着中国电影事业的飞速发展，全国各地掀起了影视制作基地的建设高潮。摄影棚作为影视制作基地中最主要也是最重要的建筑物，是电影制作企业的主要生产场所，具有较大的使用面积，属于大空间建筑，可以在其中搭置布景，布置多种灯光器材，进行影片拍摄工作。摄影棚具有体积大、空调负荷大、能源消耗量大、对空调质量要求高等民用和工业用大空间建筑的特点，同时，为适应同期录音的需要，既须隔绝外界的噪声干扰，又须使摄影棚内保持合宜的声学特性。由于其自身的特点以及拍摄功能的需要，摄影棚的空调系统不同于一般建筑的空调系统。本课题以国家影视制作基地5000平米摄影棚为研究对象，以计算流体力学和传热学为基础，对其进行分析、抽象、简化，建立了摄影棚的物理模型和数学模型，利用Fluent公司推出的专业数值模拟软件Airpak，对摄影棚内上送下回（单侧回）、上送下回（双侧回）、侧送下回（单侧回）、侧送下回（双侧回）、上送上回、侧送侧回、上送侧回等不同气流组织形式进行了模拟，分析不同气流组织形式下的温度、速度、PMV、PPD等模拟结果，并对不同的气流组织形式下热舒适性进行了评价，从而确定出最优气流组织形式。研究结论可为其它地区摄影棚的空调系统设计、改造及运行提供参考。更多还原

【Abstract】 With the rapid development of film industry in China, we set off the climax of theconstruction of film and television production bases all over the country. As the mainalso the most important buildings in the base of film and television production, studiois the main production site for film production companies。 With a character ofgreater use of the area, it is a large space building, in which you can take the setscenery, arrange a variety of lighting equipment and take film wor0k.Studio has a character of big space, high air congditioning load and high energyconsumption, and it has a higher requirement of air conditioning quality than clvil andindustrial large space buildings. Meanwhile, in order to meet the needs of therecording in the same period, both to be cut off from outside noise, but also to thestudio to maintain a decent acoustic characteristics. Due to the need of its owncharacteristics as well as camera functionality, the studio’s air conditioning system isdifferent from the general building air-conditioning system.This subject is due to the5000square meters studio in the national film andtelevision production base, which based on computational fluid dynamics and heattransfer, analyze, abstract and simplified, construct the physical and mathematicalmodels of the studio. Launched by Fluent Inc. the professional Numerical Simulationthe software Airpak, different forms of air distribution in the studio were simulated,Analysis of simulation results under different forms of air distribution, temperature,speed, the PMV, the PPD, thermal comfort and airflow organizational forms wereevaluated to determine the optimal airflow organizational forms.The research conclusions provide a reference for other parts of the studio’s airconditioning system design, transformation, and run.更多还原
