First of all, the air exchange mode of the ceiling mounted fan has three categories: the discharge type of ceiling mounted fan, the inhalation type of ceiling mounted fan, and the discharge and inhalation combined type of ceiling mounted fan. As for the discharge type of ceiling mounted fan, the fresh air goes though it from the natural-air entering entrance and exit, and the dirty air is discharged through the ventilator fan. As for the inhalation type of ceiling mounted fan, it inhales the fresh air through the ventilator fan and discharges dirty air from the natural-air entering entrance and exit. And as for the discharge and inhalation combined type of ceiling mounted fan, both of the discharge and inhalation are completed by the ventilator fan. Basically, the ceiling mounted fan is a kind of air regulator, which is driven by the motor to drive the air flow and exchange the air inside and outside the room. The purpose of air exchange is to remove indoor dirty air and adjust temperature, humidity and sensory effects.
Second of all, as we all know, the function of the ceiling mounted fan is directly determined by the air exchange rate of the top-suction fan. The top suction fan is composed of three parts: fan, motor and pipe. Therefore, the amount of air exchange of the top suction fan will be different because of the size and power of the fan blade. Therefore, if you want the ceiling mounted fan to work functionally, you must pay attention to the function of the air exchange rate so as to avoid any problem caused by it. In addition to the amount of air exchange of the suction top fan, to judge whether the ceiling mounted fan works well, it is also possible to hear whether the top suction fan of ceiling mounted fan produces noise. If the noise sounds too loudly, the ceiling mounted fan will have a bad performance. In addition, the ceiling mounted fan made of metal material can work much better. At the same time, in the use process it produces the noise to be relatively small, which will not affect everybody’s daily life.
