摘要
采用频谱分析法对ＫＣ－３２Ⅱ型单冷窗式空调器的主要振动和噪声源进行诊断，分析表明，空调器的薄板构件对振动、噪声有较大的影响。为此进行了阻尼处理，使振动量有较大的降低，噪声下降了２．０～２．５ｄＢ。
This paper offers the way to diagnose the major resource of vibration and noise from KC32_Ⅱ window air conditioner by frequency spectrum analysis method.The analysises show that thin panels are responsible for much of the vibration and noise.Based on analysises,damping treatment is taken,so vibration gets much reduced,and noise drops down by 2～2.5 dB.
