Numerical Simulation And Study Of Flow Fields With Stratified Air Conditioning In Large Space Building

In this paper, the indoor air distribution of stratified air conditioning in a large space building is studied. Firstly, the characteristics of air conditioning system and selection principles of large space building are analyzed. Secondly, the energy saving and air quality of using perforated ceiling air supply in the stratified air conditioning in a large space building has been analyzed. Thirdly, with the help of a large industrial factory building, different airflow modes of using linear slot diffusers in the middle of the side wall and using perforated ceiling air supply on the side wall are simulated by using the CFD software, at the meantime, some diagrams about the velocity, temperature, relative humidity and the concentration fields are obtained, and then, the indoor air quality is evaluated according to the analysis results in different conditions. Finally, by comparing and analyzing the simulation results, the optimal airflow modes are obtained.
