The Circulation Principle of Industrial Big Ceiling Fan

Industrial big ceiling fans can achieve natural ventilation and large area coverage, and are a solution for ventilation and cooling of tall and large spaces in summer.


As the weather gets hot, especially in summer, the indoor working temperature of the factory is getting higher and higher. The cooling effect of traditional fans is 30 degrees or higher. The heat dissipation effect is not good, and the use of central air-conditioning is really unrealistic. Industrial ceiling fans will solve these problems for you.


Industrial big ceiling fans are general industrial machinery used for space ventilation and personnel cooling. They can push a large amount of airflow to the ground and form a certain height of airflow layer on the ground to move horizontally, thereby promoting overall air circulation. Such benefits are reflected in all aspects of ground coverage and three-dimensional air circulation.


Industrial ceiling fans are based on the principle of high air volume and low speed, and function like an air mixer. It stirs a large amount of indoor air from all aspects to form a wind speed, so that the indoor air flow produces a natural wind effect. The size of air diffusion is related to the diameter of the fan, and the speed of air diffusion is related to the rotation speed of the fan blades. If the fan continues to run, the airflow will move outward until it encounters a side wall or obstacle and then rises, creating continuous air circulation.


When the blades are running, the air will generate a vortex at the end of the wing blades. The tail can eliminate this part of the energy loss, stabilize the operation of the fan, and make the airflow more in line with the principles of aerodynamics. No matter how many small high-speed ceiling fans there are, they will not produce such a large area and multi-directional breeze airflow. Usually a fan with a diameter of 2.4 meters can generate a horizontal laminar flow with a depth of about 1 meter on the ground, while a fan with a diameter of 7.2 meters can generate a horizontal air flow layer with a depth of 2.8 meters on the ground.


The natural wind generated by the large industrial ceiling fan blows to the human body, promotes the evaporation of sweat to take away heat, and cools the human body, bringing a cool feeling. The three-dimensional natural wind is more comfortable, because: on the one hand, the large industrial ceiling fan blows on the human body in a three-dimensional manner, and the human body has the largest evaporation area at this time. On the other hand, the large ceiling fan of human industry flies with the change of wind speed, and the human body naturally feels extremely comfortable and cool.
