On this hot and humid summer day, fans are definitely a small household appliance that brings a sense of happiness. As long as you turn on the switch, gusts of fresh air will blow your face, which is really pleasant

 However, there are currently a plethora of fan brands and models on the market, some of which are even more expensive than air conditioners, and some are also flashy in length Is air circulation fan an intelligence tax or not? How can you quickly choose a fan that suits you?

01. What are the types of fans and what are their advantages and disadvantages?

1. Table fan: Desktop fan, we saw it more often when we were children, but now it's very rare.

Advantage: Cheap price.

Shortcomings: Limited usage range, lack of convenience, and poor user experience.

2. Floor fan: The most common type of fan. It is mainly divided into AC floor fans and DC floor fans.

Communication floor fan, with a supply distance of about 2-5 meters, advantages: affordable price and large air volume; Shortcomings: Short air outlet distance, hard air outlet, and high motor noise.

DC floor fan, with a supply distance of about 3-7 meters, has the advantages of stable operation, long supply distance, low noise, low energy consumption, and multiple gears. Shortcomings: Compared to communication floor fans, the price is slightly higher.

3. Air circulation fan: Different from the working principle of a fan, an air circulation fan uses the principle of aerodynamics to make the wind blow out in a spiral shape along a certain direction, forming a strong airflow to stir the indoor air. Through refraction, the indoor air forms a convective circulation, thereby accelerating the flow of indoor air and achieving the effect of balancing temperature. Air supply distance of more than 10 meters.

Advantages: Concentrated wind power, strong air volume, ultra long air supply distance, low noise, and year-round availability. Combined with air conditioning, it can accelerate the circulation speed of indoor air and balance indoor temperature more quickly.

Shortcomings: The price is slightly expensive.

4. Tower fan: also known as convection fan, tower fan, based on the principle of airflow, forms a three-dimensional exchange system between indoor and outdoor air, similar to a stove blower that can supply air even without fan blades. The air supply distance is about 3-8 meters.

Advantages: Soft breeze, high safety, suitable for use in households with elderly and children.

Shortcomings: low power, low air supply, difficult subsequent cleaning, and high price.

5. Air conditioning fan: The air conditioning fan has multiple functions such as air supply, cooling, and humidification, and is a household appliance with an electric fan and air conditioning mode. Using water as a medium, it can deliver cold air below room temperature or warm and humid air. The air supply distance is about 2-5 meters.

Advantages: The blowing wind is indeed cooler and has a certain humidity.

Shortcomings: Large areas of space are not suitable, and the cooling effect will be greatly reduced. Without dehumidification function, if the room is not ventilated, it will be damp and uncomfortable. Frequent addition of ice crystals makes the operation inconvenient.

6. Vaneless fan: a fan without blades, also known as an air multiplier. The air supply distance is about 3-8 meters.

Advantages: Very safe, smooth wind, and soft wind sensation.

Shortcomings: Higher power consumption and higher prices.

02. How to quickly choose the fan that suits you?

Below 200 yuan: You can buy a good communication floor fan at this price point.

200-500 yuan: You can buy DC floor fans, air conditioning fans, and tower fans at this price range. It is recommended to buy air conditioning fans for over 300 yuan, as those that are too cheap may have a risk of water leakage. For daily use in our homes, fans in this price range are quite suitable.

500-1000 yuan: You can buy air circulation fans, tower fans, and bladeless fans at this price range.

Over 1000 yuan: No blade fan.

Motor: The preferred fan is a DC motor, which has low energy consumption, low noise, and multiple gears.

Fan blades: In terms of the number of fan blades, the more blades there are, the smaller the volume of air cut, and the softer the wind; In terms of blade shape, if you want to blow directly to cool off, choose a floor to ceiling fan with straight blade blades; If you want both cooling and indoor air circulation, choose an air circulation fan with turbine blades.

Air supply distance: The farther the air supply distance, the more it can promote indoor air circulation. The air supply distance of each type of fan has been mentioned earlier, so it will not be elaborated here.

Wind speed: According to national standards, the wind speed of household electric fans should be between 1.5 and 3.5 meters per second. The higher the wind speed, the stronger and cooler the wind. However, one cannot blindly pursue high wind speeds, as excessively high wind speeds can cause greater noise and may even make the wind uncomfortable.

Generally speaking, in terms of wind speed, the air circulation fan; DC Fan; Air conditioning fan; Tower Fan; AC Fan; Vaneless fan.

Air volume: According to national standards, the air volume should be between 10-35 cubic meters per minute. Do not purchase below the standard. The larger the air volume, the wider the coverage area.

Generally speaking, in terms of air volume, DC electric fans; AC Fan; Air circulation fan; Air conditioning fan; Tower Fan; Vaneless fan.

Other features: Choose fans with large head shaking angles, dual use on a platform, adjustable fan height and angle, and diverse control methods (touch+remote control). Functions such as humidification, purification, and heating are icing on the cake, so there is no need to overly pursue them. After all, we buy fans for coolness.

03. Inventory of High Cost Performance Fans

If the budget is limited, requires high air volume, and does not have high noise requirements, AC floor fans can be chosen; If pursuing a comfortable and low-noise feel, it is recommended to choose a DC floor fan.
