What is an Air Circulation Fan? The air circulation fan is a bit like a turbine engine on an aircraft. Its main structure includes a drive motor, a turbo fan, a guide grille and a cylindrical shell. Different from ordinary fans, the air circulation fan can let the wind blow out in a spiral shape along a certain direction, and with the stirring of the fan blades, it can finally form a spiral columnar wind. The wind blown by the air circulation fan has a long distance and good directionality. In addition, the swing angle of the head of many air circulation fans is large to match the rotation of the base. The air supply range can almost reach the entire room without moving the fan, and there is no dead angle. Of course, the purpose of the air circulation fan is to stir the air so that the indoor air forms a convective circulation, so it can be understood as an "air mixer". It is more suitable, and it can be better matched with air conditioners in summer to achieve a comfortable natural wind cooling effect. The difference between air circulation fan and ordinary fan 1. Different functions: the main function of the fan is to evaporate the water in the human body to make the human body feel "cool", while the air circulation fan is mainly to achieve a room temperature balance for air flow. 2. The operating principle is different: ordinary fans simply use electromagnetic induction to rotate the blades quickly, so that the air in front of the fan flows quickly, and the fast-flowing air passes through the human body to evaporate the water on the surface of the human body and absorb heat, so that the human body feels cool. . The main function of the air circulation fan is to form a convective circulation of the indoor air, and achieve the effect of balancing the temperature with a reasonable air flow direction. 3. The cooling effect is different: ordinary fans do not have a cooling effect on the indoor air. If the indoor temperature is high, the wind blowing out is also high temperature. On the contrary, during the working process of the fan, heat will be released, causing the temperature near the fan to rise. The air circulation fan generally cannot be directly used as a refrigerator, and is often used in conjunction with an air conditioner to achieve rapid cooling and balance the room temperature. It can also be used to circulate indoor and outdoor air, allowing indoor and outdoor air to alternate. Selection points of air circulation fan 1. Functionality: Air circulation fans play relatively many roles in daily life due to their small size. Many can be used as desktop fans, floor fans or mother and baby fans, etc. Then the air circulation fan should have the following characteristics: 1.1 rotation range, a wide range of wind blowing Generally, if the air circulation fan can turn around 180 degrees and head up and down about 90 degrees up and down, then basically this air circulation fan can reach the air supply range of the entire room after it is placed against the wall. 1.2 Wind size adjustment Since it can be used by mothers and babies on the floor or on the table, it must not only have 2 or 3 wind speed adjustments like the old-fashioned fans. Otherwise, it cannot meet the needs of the whole scene, and the wind is too strong when placed on the table, and the wind is too small when placed on the ground. Therefore, the more controllable wind gears, the more scenarios this air circulation fan can use. 1.3 DC motor Why choose a DC motor? This is related to two factors, one is the noise level, and the other is the strong wind power The quality of the motor and whether it is DC directly affect the running sound of the fan. The shadow of the DC motor is much smaller than that of the AC motor. It is also more stable, and it is not easy for the motor to overheat. And the DC motor can provide a strong wind backing for the air circulation fan. The better the motor, the more horsepower the fan has in a sense, so the air supply will be farther. The moderate wind speed of household air circulation fans is basically about 2.5~5M/S. 2. Stability The maximum wind speed of the air circulation fan is generally larger, and the volume is smaller, and the head shakes in a larger range. If the air circulation fan is not well designed, it is easy to cause the center of gravity to be unstable and the head to shake while blowing. If there are children in the family, this type of air circulation fan is relatively dangerous. 3. Noise When the motor was mentioned above, it also mentioned noise, in fact, except for the noise of the motor. Logically speaking, the greater the wind force, the greater the noise will be. However, with the advancement of technology and the reasonable design of the fan, in fact, many air circulation fans on the market can basically achieve a silent effect. Of course, this may need to be experienced by yourself or in its stores. 4. Wind distance The farther the straight-line distance of the air circulation fan is, the stronger the circulation ability must be. This is mainly determined by the air collector and the fan blades. Of course, it is also very simple to test. You must have seen it on some counters in the store. Use A balloon, if the balloon can stay stable above the air circulation fan and suspend, it basically proves that the air gathering ability of the air circulation fan is still good.
