"220V AC Cooling Fan" at work (assuming no heat transfer room with the outside world) not only did not reduce the indoor temperature, it will rise. To analyze the cause of temperature rise: When fans work, since there is a current "220V AC Cooling Fan" of the coil wire is resistance, it will inevitably produce heat outward exothermic, the temperature will rise naturally . 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 will flow together, so we can promote the rapid evaporation of sweat, with "evaporated need absorb a lot of heat, "so people will feel cool.
