Numerical Simulation and Analysis of Displacement Ventilation of Office

Xiaodong Li

Abstract

The physical and mathematical model for an assembly room with displacement ventilation system is established.Turbulent flow in the air-condition room is described by using the standard k-e turbulence model linked with the wall function,and the finite volume method is used to discrete the governing equation.According to different working conditions,the velocity field and temperature field in the room are simulated by the software AirPak.The impacts of air-in temperature,velocity and different location of the diffuser on indoor air quality are analyzed.
