"220V Cooling Fan" work (assuming no heat transfer with the outside room) the room temperature is not only not reduced, it will rise. Let us analyze a cause of temperature rise: When fans 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 increased. But why people feel cool? 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 "the need to absorb evaporation a lot of heat, "so people will feel cool.
