We have to look at the Shanxi fan air volume and pressure of the concept of Luliang fan pictures, actually refers to the amount of wind and the plane speed fan ventilation area of ??the plot. The ventilation area is subtracted from the value of the projected area of ??the outlet area of ??the tongue at the vortex obtained, the plane is the velocity of the air flow rate through time. When the plane speed is constant, the larger the ventilation area, that is, the larger the outer diameter of the impeller blades, the greater the amount of wind. The larger the amount of wind, the air, the greater heat absorption, thermal effect is more obvious fan. We use the fan, be sure to stand in the perspective of the people the right to use, the fan noise is necessary to solve a major problem of Luliang fan, specific solutions for the user detail in this section, hoping that Fans of the use of more in line with user needs. Have to carry out is the noise: in this way is a sound source placed in a small space, to control them. When sound waves hit the shield objects generated due to the resistance of Luliang fan-made, there will be a part of the sound is reflected, part absorbed, and part of that is spread out through the obstruction, thereby greatly reducing the noise. You can then re-use of sound-absorbing solution. When sound waves enter into a physical surface, the object can be sucked into energy. The sound absorption coefficient of the material by absorbing represented, the greater the absorption coefficient, the better the sound absorbing properties of the material.
