Let us analyze a cause of temperature rise: When fans work, since there is a current "220V AC Cooling Fan" coil wire is resistance, it will inevitably produce an exothermic heat outward, so temperature It will rise. But why people will feel cool it? Because the body's surface have 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 "evaporative need to absorb a lot of heat" so people will feel cool. "220V AC Cooling Fan" at work (assuming no heat transfer with the outside room) not only did not reduce the indoor temperature, it will rise.
