摘要: 随着家用空调能效标准的不断提高,传统的空调风扇罩已难以满足节能要求。为了研究10匹大风量空调外机所用的圆形风扇罩叶片参数,对风扇罩三维造型进行了流体仿真及实验验证,分析了风扇罩筋条径向间距和扭转角度对风扇罩通风量的影响。结果表明,基于CFX三维数值模拟的模型优化方法,可以有效完成风扇罩结构参数的寻优。优化后风扇罩在相同的风扇转速下,通风量提升了5.2%,这对于降低空调风道通流损耗、提高空调能效具有重要意义。

Abstract: With the continuous improvement of energy efficiency standards for household air conditioners, the traditional fan cover has been difficult to meet the energy-saving requirements. To study the parameters of the circular fan cover blades used in the outdoor units of 10-horsepower high-volume air conditioners, fluid simulation and experimental verification were conducted on the three-dimensional modeling of the fan cover. The influence of the radial spacing and twist angle of the fan cover ribs on the ventilation volume of the fan cover was analyzed. The results show that the model optimization method based on CFX three-dimensional numerical simulation can effectively optimize the structural parameters of the fan cover. After optimization, the ventilation volume of the fan cover increased by 5.2% at the same fan speed, which is of great significance for reducing the flow loss in the air conditioner duct and improving the energy efficiency of the air conditioner.
