How does an electric fan blow? The room will be cooler.

If the fan blows outside the window, it will be cool.

Blow the electric fan at the open window and pull it away at the same time, just as the air enters the plastic bag, the hot air in the room will be blown outside, so the whole room will get cold. When the distance between the fan and the window is 0.5m~2. 1m, the anemometer data is the best.

? Precautions for fan use

First of all, pay attention to the position of the electric fan.

Don't place the electric fan too close to the human body. If it is too close, the gap between blood circulation and sweat circulation will be too large. If you blow it for a long time, all organs of the human body will feel tired and the whole body will feel uncomfortable. A better electric fan is placed about 2 meters away from the human body, so that the wind is softer and more uniform.

Second, don't blow straight at people for a long time.

Never blow the electric fan directly at people, or you will catch a cold and your arms and legs will hurt the next day. Therefore, the electric fan should be set to turn its head, which is better and less harmful to the skin and body.

Third, set the wind speed.

The wind speed of the electric fan should not be too large, so as to ensure that the human body has an adaptive process. It is best to control the indoor wind speed in a small gear, especially in well-ventilated rooms and places with through flow. The wind speed of electric fans should not be too large.

Fourth, try to time the electric fan.

When blowing the fan at night, don't blow it all night, which is very bad for your health. Most fans have the function of timing, so try to time the electric fan so that you won't feel hot as long as you fall asleep. This saves electricity and is good for your health.
