Status 220V AC Cooling Fan Work

"220V AC Cooling Fan" work (assuming no heat transfer with the outside room) not only did not reduce the indoor temperature, it will rise. Let us analyze a cause of temperature rise: when fans work, because the current through the fan coil, the wires have resistance, it will inevitably produce an exothermic heat outward, so the temperature will rise. But why people feel cool it? Because the human body surface has a lot of sweat, When fans work together, 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 cool.
