Research on air distribution of air conditioning systems in auditorium of a theater

In view of the air distribution design difficulties of the air conditioning system in the auditorium of the theater building, the air distribution under the summer design condition of the benchmark scheme is analysed by means of numerical simulation. On this basis, the optimization and improvement direction of the air distribution is found by adjusting the three influencing factors including the supply air temperature, the distribution of the supply air volume of the front and rear seats, and the position of the return air outlet. Then the distribution of temperature field and velocity field in the auditorium under the optimization scheme is obtained, which provides a scientific decision-making basis for the project design.
