摘　　要：针对近年来出现的在空调室外机外加装导向栅栏板设计,利用FLUENT软件对其内部的流场、温度场进行模拟,结果表明导向栅栏能有效控制室外机排出热气流流向,极大减小了对行人的影响。同时模拟数据也显示安装栅栏后机组冷凝环境非常恶劣,进风断面温度远高于室外气温,造成冷凝效率的降低,文中也对安装栅栏前后的机组性能系数COP作了对比计算,发现导向栅栏对机组性能也有较大的影响,最后分析得出导向栅栏板适宜应用的场合。Adding barrier broad around the outdoor condenser is becoming more common in building design. The flow field and temperature distribution inside the board is simulated in this paper. Results indicate that the barrier board can efficiently control the direction of hot air flow from the outdoor condenser. Results also show that the COP of the conditioner is decreased because of the heat accumulation around the condenser. This depression is analyzed by the comparison between two amchine： one with barrier board, the other without.
