摘　　要：在国家提倡建筑节能的背景下,夏季空调室内温度标准提高已经成为一种趋势。而室内温度标准提高往往会导致室内舒适性的降低。层式通风方式作为一种近年来提出的新型通风方式,目前,国内研究的比较少。采用计算流体动力学(CFD)的方法,模拟分析对比采用层式通风、置换通风、混合通风3种通风方式。通过气流组织模拟的研究结果可知,层式通风方式比其他2种传统通风方式更能够提供好的空气品质,并且更能满足人们的热舒适度,房间整体的排污效果也更佳。研究结果可为科研及设计人员今后的工作提供一定的参考和依据。Under the background of building energy efficiency, improving the summer air conditioning indoor temperature standard has become a trend. And the improvement of standard of indoor temperature often lead to indoor comfort. Stratum ventilation as a new type of ventilation is proposed in recent years, the current domestic research is less. The method of computational fluid dynamics（CFD） is utilized to compare and simulate the stratum ventilation, displacement ventilation and mixing ventilation. Result shows that through the study of air distribution simulation, the stratum ventilation is better than the other two traditional ventilation modes with good air quality, and can satisfy the thermal comfort of people, the indoor air pollution is improved. The results can provide certain reference to scientific researchers and designers in the future.
