摘要
采用平衡不完全区组设计的方法,对影响空调器噪声的主要特征参数之一的多翼离心风机叶轮的叶片数进行实验研究,得出该参数影响程度的结论。
The experimental method based on unbalace groups is used. The blades of multi-blade centrifual fan, one of the main characteristic parameter, which influence the noise of air conditioner, is tested and analysed. The conclusion is given that the blades barely influence the noise.
