摘　　要：冷却顶板与独立新风相结合的空调系统已经得到了人们越来越多的关注和认可。本文利用计算流体力学(CFD)的方法,对使用冷却顶板与独立新风相结合的办公建筑进行了计算模拟,并对室内空气的速度场、温度场、垂直温度梯度进行分析,认为该系统能提供良好的室内舒适性。The ceiling radiant cooling panels combined with the isolated outdoor air systems has received more and more attention and acceptance. By using the method of Computational Fluid Dynamics （CFD）, the office building is simulated which used the ceiling radiant cooling panels combined with the isolated outdoor air systems, and the indoor airflow velocity field, the temperature field and the vertical temperature gradient of the building are analyzed. The result shows that this system can offer a good indoor climate condition for people.
