Air distribution design for large-screen projection wall in large monitoring centers

Based on the design concept of “large-screen projection wall air conditioning return air cooling system”, the CFD simulation is used to analyse the air distribution in a tall space of a large monitoring center, and an air conditioning supply and return air scheme that can make the surface temperature distribution of the large-screen projection wall uniform and control the temperature difference within the range of 2 ℃ is obtained, which not only meets the working temperature requirements of the large screen and prevents the image distortion of the large screen due to temperature difference deformation, but also meets the comfort requirements of personnel working area.
