空调机的主要噪声源是风机,为了降低空调机的噪声,近年来许多人在研究低噪声风机方面做了不少工作,取得了一定进展。我院去年与哈尔滨制氧机厂合作研制成空调用的整体冲片式前向多翼风机,取得了良好的低噪声效果。然而,空调机的噪声还与空调机内空气流动阻力密切相关,降低空调机的流动阻力同样可以取得降低噪声的效果,研究空调机的流动阻力与研究低噪声风机具有同等重要
The main noise source of air conditioners is fans. In order to reduce the noise of air conditioners, many people have done a lot of work in researching low-noise fans in recent years and have made some progress. Last year, our institute cooperated with the Harbin Oxygen Making Machine Factory to develop an integrated punching-type forward multi-blade fan for air conditioning, achieving a good low-noise effect. However, the noise of the air conditioner is also closely related to the air flow resistance in the air conditioner. Reducing the flow resistance of the air conditioner can also achieve the effect of reducing noise. It is equally important to study the flow resistance of the air conditioner and to study the low noise fan.
