| Abstract: | The effect of protecting mesh of air conditioner outdoor unit on aerodynamic noise is studied with experimental method. Test result shows that, there are important effect of protecting mesh diameter on noise spectrum distirbution. Thus during design of air conditioner outdoor unit, the matching about fan exit flow velocity and wire diameter of protecting mesh is an important method for decreasing noise. |
