摘　　要：比较了混合通风、置换通风、地板送风和碰撞射流通风这4种送风方式的特点,利用试验方法实测了这4种方式下空调房间的室内温度、气流速度和CO2质量浓度分布,讨论了室内热环境特点的异同,对比分析了4种送风方式下室内热舒适性、污染物分布特征,并对送风能量利用情况做了估计.The characteristics of four air supply modes including mixing ventilation, displacement ventilation, underfloor ventilation, and impinging jet ventilation are compared. Indoor air temperature, air velocity profiles and CO2 mass concentration distributions are measured by a series of experiments. The differences of indoor thermal environment among the four air supply modes are discussed and analyzed, and the thermal comfort, pollutant distribution features and energy utilization of the four air supply modes are compared and estimated.
