摘　　要：为选择既能满足室内空气品质和室内人体热舒适又更节能的办公室通风模式,以某办公室为研究对象,通过采用计算流体力学(CFD)的方法研究了在总送风量不变的情况下,模拟混合通风和层式通风的人体头部和脚部处温度场、速度场、PMV指标和空气龄。研究结果表明:层式通风具有温度更适宜、热舒适度和空气品质更好的特点,在办公室内呼吸区通风效率也优于混合通风,且比混合通风更节能。In order to select an office ventilation mode that not only meets indoor air quality and indoor human thermal comfort,but also more energy-efficient,an office is used as the research object and the Computational Fluid Dynamics(CFD)method is used to simulate the temperature field,velocity field,PMY index and air age at the head and feet of human body with mixed ventilation and stratum ventilation under the constant total air supply volume.The results show the stratum ventilation has the characteristics of more appropriate temperature,thermal comfort and better air quality.The ventilation efficiency in the breathing area in the office is also better than the mixed ventilation,and it is more energy-saving than the mixed ventilation.

关 键 词：层式通风 混合通风 热舒适性 CFD
