摘　　要：通过CFD模拟研究了碰撞射流系统末端不同送风形式,对各送风形式下室内的速度场和温度场的分析结果表明:典型工况条件下,在送风末端管壁处设置小开口以及百叶会使近地面扩散气流速度明显降低,可以降低冬季工况室内人员产生冷风感的风险。所有送风口形式均有下部空间温度高于上部特征,可实现较高的送风能量利用效率。Different air jet system outlets are studied by CFD simulation. Analysis of results of the velocity field and temperature field conditions showed that setting louvers and small openings near the ends of the outlet will lower the air distribution distance as well as the distribution velocity cold by the wind. All conditions are characterized by a achieve high energy efficiency air supply. under typical operating conditions, so indoor people will not feel lower space temperature is higher than the upper part, which can
