摘　　要：空调房间热分层现象是普遍存在的现象,特别是在上送风时尤甚.热分层会造成空调效果不佳,这在空调设计时特别要注意避免的问题.本文主要探讨上送风情况下空调房问流场的分布情况,特别是温度场的分布情况.通过使用FFSV3.0仿真程序,分析了上送风时各种参数下的流场分布,得到了热分层高度与送风温度和速度的关系,并把仿真结果同实验值进行了对比。所得结果对空调设计具有重要的参考价值。The phenomenon of delaminating exists popularly in air supply system of air-conditioning , especially on the occasion of ceiling register air supply, which results in the bad effect of air- conditioning, and should be prevented in the air- conditioning design. In this paper the air distribution of ceiling air supply in air - conditioned room is discussed, and the temperature distribution in this case is a major concern. With the help of the software of FFSV 3.0, all the air distribution of varying properties are analyzed, and the relationship belween the heights of delaminating and air supply velocity and temperature is gained. The results are compared with the experiments, which can be referred to by the engineers in air- conditioning.
