220V Cooling Fan cooling principle

When "220V Cooling Fan" work, not only did not reduce the indoor temperature, it will rise. The main reason is this: When the fan work, since there is a current "220V Cooling Fan" coil wire is resistance, it will inevitably produce an exothermic heat outside, so the temperature will rise. So why do people feel cool? Experts said that because of 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 " evaporation need to absorb a lot of heat, "so people will feel cool.
