so people will feel cool

When the floor standing fans work (assuming no heat transfer with the outside room) not only did not reduce the indoor temperature, it will rise. To analyze the cause of temperature rise: When fans work, due to the current through the fan coil wire is resistance, it will inevitably produce an exothermic heat outside, the temperature will rise naturally. But why people will feel cool it? Because the body's surface have 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, heater with fans so people will feel cool.
