Date: 2015-8-4   Click: 1496 Times

"220V Cooling Fan" The main components are: AC motor. Its working principle is: electrical coil in a magnetic field by the force rotates. 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. Not only did not reduce the indoor temperature, it will rise. Cause of temperature rise is: The "220V Cooling Fan" work, since the 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.
