Study and simulation analysis on improved stage space thermal comfort

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.
