摘　　要：针对大型公共建筑高大中庭夏季供冷出现的顶部温度过高、底部温度过低现象,结合中庭自身特点提出三种空调送风方案,并利用计算流体力学法(CFD)综合考虑温度和风速两种控制目标,优化高大中庭及周边区域室内热环境,满足热舒适的同时利于节能。Aimed at the excessive high temperature at top and excessive low temperature at bottom that occurs in high and large atrium of public buildings during cooling in summer,three air supply schemes are proposed,combined with the characteristics of the atrium.Temperature and wind speed are considered synthetically by computational fluid dynamics(cfd).Optimize the indoor thermal environment of the large atrium and surrounding areas to meet the thermal comfort and at the same time to save energy.
