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。
Air-conditioned room thermal stratification phenomenon is a ubiquitous phenomenon, especially in the air supply especially when the thermal stratification will result in poor air conditioning, air conditioning design, special attention should be paid to avoid the problem.In this paper, The distribution of the flow field in the air-conditioned rooms, especially the distribution of the temperature field is discussed.FFSV3.0 simulation program is used to analyze the distribution of the flow field under various parameters of the upper air supply, Wind temperature and speed of the relationship between the simulation results and experimental values were compared. The results of the air conditioning design has an important reference value.
