Abstract

Adopts numerical simulation, calculates the air flow of a typical office which apply displacement ventilation, analyzes the characters of the distribution of field of velocity and temperature. Then, evluates its performance by PPD,PMV and THE AGE OF AIR, draws a conclusion that the displacement ventilation can maintain a thermally comfortable environment and provides better indoor air quality.
