| 摘 要： | 各品牌的中央空调多联室外机均采用双风轮系统,都存在不同程度的低频脉动异音,异音呈低频特性,易让人产生烦躁感.双风轮系统在旋转基频比较接近的情况下运转时,旋转噪声叠加后产生拍振异音,其频率等于双风轮的旋转基频差.旋转噪声是拍振腹能量的主要来源.本文设计了新三叶风轮,采用新三叶风轮与原四叶风轮组合方式运行.同时测试两风轮的...

| Abstract: | The outdoor units of the Variable Refrigerant Flow air conditioning system manufactured by the top brands of the world are all using double-fan system.However,they generate varying degrees of pulsation noise,with the low frequency features making it easy for people to feel dysphasia.When the double fans operate at nearly the same Blade Passing-by Frequency,noise of beating vibration will be generated.Its frequency is equal to the difference of the blade passing-by frequency of the double fans.Rotated noise ... |
