Simulation Analysis And Design Of Air Distribution In The Theater Of Xinjiang

As a media of communication culture,theatre is more and more popular in people’s life,because of its unique architectural features and characteristics,the airflow organization design has always been a difficulty in the design of theater air conditioning system。How to combine the characteristics of specific projects and design reasonable airflow structure is the key to the success of theater air conditioning designThe main part of the theatre is the stage and the auditorium,the difficulty of stage airflow organization design is that it can effectively eliminate the large amount of heat load caused by lighting and equipment,and satisfy the thermal comfort requirements of human body;the audience hall density,will produce a lot of heat and moisture load,so the design of airflow in the audience hall need to eliminate the moisture loss and heat loss at the same time,which can ensure the airflow distribution uniformity and can meet the requirements of human thermal comfort.Combining with the example of Xinjiang Grand Theater,this paper expounds the design process of airflow in the theater,and puts forward reasonable solutions according to its own characteristics.In the design of airflow distribution in this project,the Fluent software is firstly applied to simulate the velocity field and temperature field in the stage of the auditorium,through the plan comparison,it is concluded that the stage should adopt the side delivery,the next time,the stratified air flow organization mode;and the audience hall should adopt the lower delivery and the last displacement type air flow organization mode.According to the simulation results of Fluent,the air conditioning system design of Xinjiang Grand Theater was carried out.In the later stage,the actual running effect of the project is analyzed by tracking test,the result shows:the control system can control the precooling time and the design requirement of air distribution,the original precooling time was further improved,and the rationality of the air distribution design was verified,which provides a reference for air distribution design of super large theater.
