What are the working principles of wall hanging fan types?

After many years of development, the wall hanging fan industry has matured day by day. Have you ever imagined in your childhood what makes the wall hanging fan turn? Today, although the appearance of the wall hanging fan is constantly changing, its working principle is basically unchanged. And how much do you know about the working principle of wall hanging fans? You will know after reading the following article. The working principle of wall hanging fan The main component of wall hanging fan is: AC motor.

      Its working principle is: the energized coil rotates under force in a magnetic field. The energy conversion form 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. When the wall hanging fan is working (assuming that there is no heat transfer between the room and the outside world), the indoor temperature not only does not decrease, but increases.

      Let's analyze the reasons for the temperature rise together: When the wall hanging fan is working, because there is current passing through the wall hanging fan's coil, the wire has resistance, so it will inevitably generate heat and release heat outward, so the temperature will rise high. But why do people feel cool? Because there is a lot of sweat on the body surface of the human body, when the wall hanging fan works, the indoor air will flow, so it can promote the rapid evaporation of sweat, combined with "evaporation needs to absorb a lot of heat", people will feel cool .
