改善舞台空间热舒适的模拟分析研究

Study and simulation analysis on improved stage space thermal comfort

为解决暖通设计中普遍存在的舞台下部演员活动区温度常常得不到保障的问题,采用CFD计算流体力学方法,对上海市某歌剧厅舞台空间的空调系统进行了数值模拟计算,并设计了一种台仓加热系统。分析了4种工况下舞台演员活动区温度和风速的分布情况。结果表明:是否考虑辐射作用会对结果产生一定的影响,考虑辐射作用的结果更接近真实情况;台仓加热系统在运行1h后温度基本达到稳定,可以很好地改善冬季舞台下部演员活动区热舒适性差的问题。

In order to solve a common problem that the temperature of the actor’s activity area is often not guaranteed in stage HVAC design,simulates the air conditioning system of an opera hall in Shanghai by CFD method,and designs a understage heating system.Analyses the temperature and wind speed distribution of the stage actors’ activity area under four working conditions.The results show that the radiation effect will have a certain impact on the results,and the result considering the effect of radiation is closer to the real situation.The temperature is basically stable after one hour’s operation of understage heating system,which can well improve the thermal comfort of the actors’ activity area at the lower part of the stage in winter.
