When selecting air-conditioning fans, the first thing you should look at is quality assurance, and whether there are 3C national certification labels, certificates, trademarks (instructions for use), warranty certificates and other related materials. Generally, the electrical appliances produced by regular manufacturers will have these, which are qualified and verified, and can be guaranteed whether in use or after problems occur.

Shell material

Attention should be paid to the material used in the shell of the cold fan. Relatively speaking, it is better to use ABS plastic material, and the word ABS will be printed on its shell, and the gloss is better. This material not only has good high temperature resistance, but also has good corrosion resistance and impact resistance. If it is a recycled material, it is easier to see that its brightness will be poor.

3/5

Operation

Air conditioning fans bring us cool air, so there should be some requirements for its operation, and it is best to send out uniform air volume. I suggest that you choose a large air outlet, so that the scope of action of the fan blades is relatively large, which can drive away the hot air around us and feel much cooler.

4/5

water curtain

Another point is to look at its water curtain, which should be reasonable in design, so it is cooler. It is best to choose a cold fan equipped with anti-blocking, which can avoid blocking to a great extent.

5/5

motor

In addition to its features, the motor inside it should be known and stable during operation. In addition, it is better to have an over-temperature automatic power-off device, which can protect the motor from damage due to high temperature to a great extent. A high-quality motor won't make too much noise, and its noise will be relatively small. The motor with poor quality will make a loud noise, which will also affect the family.
