Industrial large ceiling fan principle:
The unique airfoil design of industrial large ceiling fan reduces the air resistance in operation to the limit, efficiently converts electric energy into air kinetic energy, pushes a large amount of air from the roof to the ground in a conical shape, and forms an airflow layer of 1-3 meters indoors. When the airflow reaches the ground, it flows horizontally, and when it encounters obstacles or parallel airflow, it flows upward to the roof, creating a large coverage area that is not limited to the lower part of the fan. In open spaces, industrial ceiling fans can reach 14850 m3/min.
The airflow layer formed by the industrial large ceiling fan is similar to the breeze system in nature. When the human body is placed in it, it feels a three-dimensional wind from all directions, which will maximize the evaporation area of sweat and reduce the temperature by 5-8. At the same time, it can also maintain the moisture of the human body, greatly improve the comfort of the human body, and avoid the health problems caused by traditional high-speed fans.
The principle of FRP horn fan:
FRP horn fan uses the principle of air convection and negative pressure ventilation, and uses mechanical kinetic energy to make the fan run, so that the hot air, peculiar smell and black smoke trapped in the factory are discharged out of the window in a short time. At the same time, outdoor fresh air is circulated and exchanged with the interior, and the temperature drop can reach 3-5.
The industrial large ceiling fan adopts PMSM permanent magnet synchronous motor or imported geared motor to achieve maintenance-free or low-maintenance. The electromagnetic noise is as low as 39 decibels, and almost only the wind is heard during operation. Aircraft-grade materials guarantee the service life of industrial ceiling fans, generally more than 10 years.
The FRP horn fan adopts a direct-connected motor, which avoids the corrosion and wear of the belt and realizes maintenance-free. Low noise, stable operation, large air volume. The shutter is designed using the principle of air flow, it does not require electricity and personnel to close, and can prevent the intrusion of rain and open automatically. The shell is made of FRP, which is acid and alkali resistant, anti-corrosion, and prolongs the service life.
