The wind of an electric fan is in one direction, one volume, one speed and one pressure, which are fixed. Natural wind changes, and of course it is different in large areas. Furthermore, in order to achieve balance, the human body has to cool down and heat up when there is wind and not, which of course makes it uncomfortable.
Can an electric fan lower the indoor temperature? I think it can. But today I talked to my classmates for a long time and they insisted that it can lower the temperature. Let me ask.
Wind (natural phenomenon) is caused by air flow. A natural phenomenon caused by solar radiation heat. Sunlight shines on the surface of the earth, causing the surface temperature to rise. The air on the surface expands due to heat and becomes lighter and rises. After the hot air rises, low-temperature cold air flows in laterally. The rising air gradually cools and becomes heavier and falls. The higher surface temperature heats the air and causes it to rise. This flow of air creates wind. The wind created by such a large-scale air flow cannot be easily achieved by humans. Even if you can do it, it won't last long.
Another type of wind is powered wind, such as fans, air conditioners, fans we used to use, and wind power plants. These create wind by pushing air through power. These winds can be created by humans.
Well, as for the question of what constitutes wind, wind should be a phenomenon and should not become a substance.
As for making wind, the difference between artificial production and natural formation It should depend on the size and scope of the wind. The principle can be understood, but there is not enough power to complete it. The power of nature is incomparable to humans. The wind created by humans is just a disguised form of using other kinetic energy to replace the kinetic energy naturally generated due to air pressure differences, but it is less powerful.
The electric fan will make your own liquid evaporate faster, and evaporation must absorb heat. When the liquid evaporates and absorbs the heat of your body, you will naturally feel cooler. This is why using an electric fan is cooler after sweating. reason. Electric fans will only create wind to increase the evaporation rate and cool you down, but will not lower the temperature.
