Myth: Fans Keep a Room Cool

When you feel hot you would like to turn on a fan, which will cool you off. But the fan does not cool everything as you wish. Fans make the room hotter.



Why does fun not work for cooling and increase in temperature instead? It's mainly due to the fact that the fan is an electrical device. The fan has a coil of wire with electric current running through it. The more current, the hotter the wire gets. All the electricity that is driving the fan turns directly into heat. The fact is that electric currents make things hot. So, with a fan in a closed room and an electric current, the room will warm up finally. So a fan does not cool the room at all.

 But the wind has little effect on the actual temperature unless the fan mixes hot and cold air in the room. The wind makes people feel cool by replacing the hot air above the skin surface with colder ambient air. That’s why we will feel cooler when we feel so hot after coming back home and turn on the fan, it works well at first. A fan makes you feel cooler when it blows on you by moving air across you more rapidly than normal. This breaks up the thin layer of warm air near your body and lets it be replaced by cooler air for a while, and it aids evaporation of sweat from your skin, which also cools you.



So we would suggest you could add a basin of water or evaporation if you feel the fun does not work. By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin and this is how you could eliminate body heat. You will get cooler after more evaporation in the room.

Or you could also open your window or near the window, that would work well for you, cause it helps draw cool air into the home or create a cross current to exhaust some of the hot air trapped inside.
