摘　　要：针对典型建筑房间,通过建立物理模型与数学模型并结合CFD模拟方法,研究室内热舒适性随混合通风、置换通风和地板孔板通风三种通风方式的送风条件变化的敏感性,得到人体前后侧0.2m处空气龄、温度场、PMV、PPD分布及变化特征。研究结果将为不同通风方式下合理选择送风条件以改善室内人体热舒适性提供理论指导。As to typical building space, its physical model and mathematic model were established. Moreover,combined with CFD, variation sensitivity of indoor thermal comfort with ventilation conditions was determined for mixing ventilation, displacement ventilation and floor perforated panel ventilation. Meanwhile, distribution and variation characteristics of air of age, temperature, PMV and PPD at 0.2 meter front and back of human body were obtained. The results provides theoretical guidance for reasonably choosing air supply conditions to improving indoor human thermal comfort under different ventilation patterns.
