某空调房间上送下回气流组织的数值模拟

Numerical Simulation of Air Distribution of Up-Supply and Down-Return in an Air-Conditioned Room

采用数值模拟方法,利用FLUENT软件模拟了不同情形下两种气流组织形式下空调区的二维温度场、速度场的变化情况及差异性,通过模拟结果分析了回风口的位置对整个空调房间的流场和温度场的影响,结果表明采用上送异侧下回的方式时,室内的气流组织分布较好。当室内送风方式选择上送下回时,送、回风口最好对角布置,以提高送风作用的有效性。

Using numerical simulation method,FLUENT software was used to simulate the variation and difference of two-dimensional temperature field and velocity field in the air-conditioned area under two different airflow modes.Through the simulation results,the influence of the position of the return air outlet on the flow field and temperature field of the whole air-conditioned room is analyzed.The results show that the airflow organization in the room is better when the position of inlet-vent and outlet-vent are on different sides of wall.When the inlet-vent is on the top and the outlet-vent is on the bottom,the inlet-vent and outlet-vent are preferably arranged diagonally to improve the effectiveness of the air supply.
