分体式空调室内气流组织CFD仿真优化

CFD simulation optimization of indoor air distribution in split air conditioner

随着社会经济的发展,人们对室内环境品质要求越来越高,对于空调的需求也逐渐向舒适性方向发展。本文基于CFD流固耦合数值模拟探究空调循环风量及制冷量对高层空调建筑房间的降温速率及温度场、流场均匀性的影响,并对房间气流组织分布进行数值模拟分析。结果表明:在循环风量为700 m^(3)/h时,房间温度均匀性最好;空调制冷量越大﹐房间纵向温差越大,横向温差越小。空调循环风量和制冷量对室内气流组织分布有着不同的影响,应综合考虑进行优化。

With the development of social economy, people have higher and higher requirements for indoor environment quality, and the demand for air conditioners has gradually developed toward comfort.Based on the CFD fluid-solid coupling numerical simulation, this paper explores the influence of air conditioning circulation air volume and cooling capacity on the cooling rate, temperature field and flow field uniformity of high-rise air-conditioned building rooms, and conducts a numerical simulation analysis on the airflow distribution of the room.The results show that the temperature uniformity of the room is the best when the circulating air volume is 700 m^(3)/h;the greater the cooling capacity of the air conditioner, the greater the longitudinal temperature difference of the room and the smaller the lateral temperature difference.Air conditioning circulation air volume and cooling capacity have different effects on indoor air distribution, and should be optimized through comprehensive consideration.
