Summer night, it’s cold outside. Why is the house still sultry? This is a puzzle for many people.
The answer is very simple because the indoor and outdoor airflow capacity is limited; the indoor hot air can not go out; the outdoor cold air can’t come in.
An air circulation fan can solve this problem well.
What is an air circulation fan?
Through the principle of aerodynamics, the air circulation fan forms a biga strong air volume, agitates the indoor air, and through refraction, makes the indoor produce convection wind, thus accelerating the indoor air circulation.

The purpose of the air circulation fan is to stir the air and make the indoor air form convection circulation.
So it can be understood as an “air mixer,” its purpose is not to blow people, but to speed up the airflow.
What is the difference between air circulation fan and traditional fan?
1. The air circulation fan doesn’t need to blow directly at people
The traditional fan is basically to accelerate the moisture or evaporation on the skin surface, take away the heat of the human body and achieve a cool and comfortable effect, which can only be achieved by blowing at people.
And the air circulation fan is through agitating the air, making the indoor air blend, and forming convection again, aiming at the indoor air circulation. Therefore, the general circulation fan does not blow directly at people.
2. Air circulation fan is applicable all year round
Spring and autumn can make the indoor air as fresh and fresh as the outdoor air.
Summer with air conditioning, can quickly reduce and balance the indoor temperature.
In winter, the air circulation fan is used together with the heating, and the heating effect is faster and more uniform.
How To Choosing the Best Air Circulator Fans
Air supply distance
In the air supply distance, of course, the farther, the better.
When the air supply distance is far enough, it can easily reach the walls, roofs, and other obstacles in the home environment. When the wind meets these obstacles, it will form refraction and spread to all angles, stirring more indoor air.
Electric machinery
The motor is the core component of the electric fan. The quality of the motor directly determines the service life of the electric fan. The BLDCM is superior to the standard AC motor.
Because the resistance of the BLDCM is balanced, the torque is even, and the rotation of the motor is smoother, it can be controlled accurately and accurately with high precision, so that the fan can switch smoothly within a specific speed range, and reduce the blade jitter.
Besides, we have to look at the core material of the motor. The common materials of the core are pure copper core, copper-clad aluminum core, and aluminum wire core. The pure copper core has the highest permeability, small attenuation coefficient, the longest service life, and the most expensive cost。
Air supply angle and gear selection
The shaking angle of the air circulation fan determines its air supply angle. The larger the air supply angle is, the better.
A good air circulation fan should also provide enough gears, including different wind speeds and intensities.
The greater the wind speed, the better the air convection effect, but the greater the noise, users can choose according to their actual needs.
Which functions are more practical?
Timing function
When the power is on, and the power is not on, select “timing” to reserve power on; when the power is on, select “timing” to reserve power off.
The user can set the time for the fan to turn on and off by himself, such as 1 hour, 4 hours, and 8 hours later. The timing function is very convenient.
memory function
When the air circulation fan with memory function is started again, it will automatically switch to the operation state when it was last closed, and no need to reset.
Room temperature display
Some air circulation fans have a display screen, which will showroom temperature, which can play a reference role.
Design of separated power supply
The air circulation fan is a frequently moving object. The separated power supply design can make the movement more convenient.
Body induction
Some air circulation fans have the function of human body induction. In a certain range and time, if the presence of human beings is not sensed, they will turn off automatically. When someone is sensed approaching, they will turn on automatically.
