News – how fans work:

Fan, refers to the hot weather with the wind to cool the appliances. The electric fan is a device driven by electricity to generate air flow. After the fan is powered on, it will rotate and turn into natural wind to achieve cool effect.

The main components of electric fan are: AC motor. Its working principle is: the electrified coil rotates under the force 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 electrical energy will be converted into thermal energy.

When the electric fan works (assuming that there is no heat transfer between the room and the outside), the indoor temperature will not decrease, but will increase. Let’s analyze the cause of the temperature rise: when the electric fan works, because there is current passing through the coil of the electric fan, the wire has resistance, so it will inevitably generate heat and release heat, so the temperature will rise. But why do people feel cool? Because there is a lot of sweat on the body surface, when the electric 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.
