摘要
采用CFD数值模拟方法研究通风口位置对于置换通风与混合通风形式下室内速度场以及温度场的影响,并讨论室内PD（percentage of dissatisfied）值、垂直温差ΔT、通风效率η随通风口位置的变化规律.分析得出,办公室类房间采取混合通风模式,并将进风口位置设置于天花板右侧位置时办公室内空气环境最佳.
In this paper,the CFD numerical simulation method is employed to study the influence of vent position on indoor velocity field and temperature field under displacement ventilation and mixed ventilation;and then the change rule of indoor PDvalue,vertical temperature differenceΔT,and ventilation efficiencyηwith the position of vent is discussed.It is concluded that the indoor air environment is at its best when the mixed ventilation mode is adopted in the office room with the inlet positioned on the right side of the ceiling.
