摘　　要：为了揭示风机旋转气流对库内气流分布特性的影响,建立了风机及冷库的物理模型和数学模型,冷风机采用FAN模型,进行了数值模拟研究,得到不同运行工况下的速度流场和速度矢量分布,经分析得出各参量对流场的影响规律。In order to reveal the influence of swirling eddy for the flow distribution characteristic in the cold storage, the physics model and mathematics model for packaged air conditioner was established. FAN model was adopted for the simulation of air-cooler. Velocity field and velocity vector were gained under different operating condition. The effect law of the flow field affected by each parameter is educed by analyzing the simulation results.
