When "220V AC Cooling Fan" work, because of the current through the fan coil wire is resistance, it will inevitably produce exothermic heat outward, so the temperature will rise. But why do people feel cool? Because the body's surface has a lot of sweat, when after "220V AC Cooling Fan" Working together, the indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with "evaporation needs absorb a lot of heat, "so people will feel cool.
