摘　　要：为了对比混合通风与置换通风两种不同通风方式下空调房间的气流组织情况,采用计算流体力学数值模拟的方法,对空调房间的速度场、温度场和CO2浓度场进行模拟,通过对比得出,采用置换通风要比混合通风的空气品质更好。To compare air flow of air-conditioning room by two different ways of mixed ventilation and displacement ventilation,this paper adopted the numerical simulation method of computational fluid dynamics to simulate velocity field,temperature field and CO2 concentration field in air-conditioning room. By comparison,the results showed that air quality of displacement ventilation was better than that of the mixed ventilation.
