结合空调器室内机用贯流风机系统的结构特点 ,分析了影响其气动噪声和产生异声的原因 ,通过采用四折蒸发器和蒸发器局部倒片的结构 ,有效地控制气动噪声源 ,试验与使用效果明显。
Combined with the structural characteristics of the cross flow fan system for indoor unit of air conditioner, the reasons that affect its aerodynamic noise and generation of abnormal noise were analyzed. By adopting the structure of partial rewinding of evaporator and evaporator, the aerodynamic noise source was effectively controlled. With the use of obvious effect.
