摘　　要：分析高大中庭气流运动的特点,结合实际工程,采用对中庭进行CFD数值模拟计算,获得中庭的温度场和速度场的分布。结果显示,分层方式的空调能使室内的温度及送风速度达到设计要求,并且能达到下部人员活动区的温度均匀性要求,符合人们对舒适度及节能的要求;同时上部非空调区温度较高,达到节能效果。Based on an analysis of atrium air movement and its simulation by CFD software with actual engineering,the distribution of temperature field and velocity field were obtained. The results show that stratified air conditioning can make indoor temperature and air speed meet the design requirements,make the lower zone＇s temperature uniformed for staff activities,and also meet the people requirements for comfort and energy-saving. At the same time,the temperature is higher in the upper part without air conditioning,which can achieve the effect of energy saving.
