Abstract :
In order to study the displacement ventilation system in winter, TVOC concentration field, velocity field and temperature field are simulated by FLUENT software which use standard k-ε turbulence model combined with wall function method. The study conclude that in winter displacement ventilation can be achieved by using ceiling radiant heating system and warm air-curtain which is set in the cold wall.
