Drive away the hot and dry weather to the power of the electric fan is recommended

Sometimes people always like to miss, miss the past time, miss those happy days that belong to us. Think about the time before there was no air conditioning, we always in twos and threes under the tree to cool, and occasionally in the evening very accompanied by the cool breeze out. At that time, the electric fan at home became the most important refrigeration tool, and the family was crowded in front of the electric fan, trying to cool down. Today, electric fans have become more intelligent after continuous development. The main components of the electric fan are: AC motor. The working principle is: the energized coil is forced to rotate in the magnetic field. The form of energy conversion is: electrical energy is mainly converted into mechanical energy, and because the coil has resistance, it is inevitable that a part of the electrical energy will be converted into heat energy. But why do people feel cool? Because there is a lot of sweat on the body surface of the human body, when the electric fan works up, the indoor air will flow up, so it can promote the rapid evaporation of sweat, combined with "evaporation needs to absorb a lot of heat", so people will feel cool.
