Many shopping guides come up with fan blades, power, and noise, which are useful but very limited, because this is only applicable to traditional electric fans! What does tradition mean? Are there unconventional electric fans? This comes to the types of electric fans. There are many electric fan products on the market, but there are only 4 types in terms of types.
1. Traditional electric fan
This type of electric fan is most familiar to everyone, including ceiling fans, Floor Fans, table fans and so on. The principle of this type of fan cooling is that the motor drives the fan blades to generate strong wind to make the air flow, accelerate the evaporation of human sweat, and make people feel comfortable. The fan has a large air outlet angle and a wide coverage area, which is very good for cooling. The disadvantage is that the distance of the wind is limited, and there is almost no cooling effect beyond 3 meters. At present, the mainstream on the market are table fans and floor fans. The purchase of these two models is based on power and number of fans. The power is generally about 30w-60w, and the fan leaves are divided into 3 leaves, 5 leaves, 7 leaves, and 9 leaves. The greater the power, the greater the air volume, the more the fan blades cut the smaller the air, and the softer the wind is on the person. When buying, please pay attention: the same number of blades, high power, although the air volume is large, but the noise also becomes correspondingly large. At the same power, the fan blades become softer with more wind, and the noise will be smaller, but the corresponding air volume will also be smaller. Therefore, it is best to choose a 5-leaf fan with a power of about 60w, which guarantees both air volume and comfort, and the noise is not large.
2.Air circulation fan
The shape of this fan is a unique turbine design. This design can make the wind blow farther. It can form convection in the room to speed up the indoor air flow. It is very good for use with air conditioners and can quickly cool the room more quickly. It's very simple to buy, just look at the value, and just look at the price.
3. Air-conditioning fan
The principle of this fan is that there is an additional water tank inside, which can put water and ice crystals, ice packs and the like in the water tank. The temperature of the blowing wind will be lower. But you can count on lowering the indoor temperature, telling you that you can't do it, and the models are generally bulky. In addition, the user experience is not good, because you always have to remember to add water and ice packs, and the models with high power are very noisy, and the air volume with low power is low. This model is only recommended for purchase in the following two environments: One is a small bedroom. Buy a small-capacity model. It blows cool on the body, the noise is not large, and it is very cool to use. Second, open spaces such as supermarkets or factory workshops that don't need to pay attention to noise. It is really cool to buy a high-powered model. There is not much to say about the purchase of this model. The small bedroom is about 60w. The larger the open space power, the larger the water tank capacity.
4.Tower Fan
This type of fan is also called a leafless fan, and the wind is generated by the motor driving the wind wheel.
This type of fan is suitable for users with children at home. It has a high safety factor. In addition, because there is no fan blade to cut the air, the wind blows out is softer, more comfortable and does not occupy land. But this kind of fan noise will be relatively large, the air volume is smaller than the blade type fan. If you want to buy this model, pay attention to the size of the wind wheel when purchasing. The larger the wind wheel of the same power model, the greater the air volume; look at the air supply angle, the larger the air supply angle, the better the practicability; whether mechanical or remote control , Remote control is more practical and the price is higher.
