Numerical simulation of displacement ventilation air-conditioned room based on CFD

Zhitao Wang

Abstract

By taking air supply displacement ventilation air-conditioned room as an example,the computational fluid dynamics software,which uses two-equation turbulence model,was adopted to simulate the room's temperature field and the concentration of pollutants.The advantages of displacement ventilation in the human body to improve thermal comfort,indoor air quality,energy-saving and so on are revealed.The simulation result of improving indoor air quality has guiding significance.
