"220V Cooling Fan" working principle is: the coil is energized to rotate by force in a magnetic field. Form of energy is transformed: the main electrical energy into mechanical energy, and because the coil has a resistance, so that there is an inevitable part of the electrical energy to be converted into internal energy. "220V Cooling Fan" work the room temperature is not only not reduced, it will rise. Let us analyze a cause of temperature rise: When fans work, due to current through fan coil wire is resistance, it will inevitably produce an exothermic heat outside, so the temperature will rise. But why people feel cool it? Because the body's surface has a lot of sweat, when after "220V Cooling Fan" Working together, the indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with "evaporative need to absorb a lot of heat," so people will feel to cool.
