摘要：
Using CFD simulation, analyzes the effects of differences of heat source distributing on the airflow organization of displacement ventilation, accounts for the characteristics on removing the remaining heat when using displacement ventilation, and at the different heat source distributing, the similarities and differences of temperature field and velocity field, points out the merits of displacement ventilation on assuring the indoor air quality.
