Explain the following statement you feel cooler on a hot day when you turn on a fan even though the air being blown around is hot?
Before you turn on a fan, the air is essentially hot because it is still and there is no circulation byconvection of the air currents. When you turn on the fan, it sparks a circulation where the hot air at the top flows to the opposite side of the room, and then eventually becomes cooler and more dense, falls to the floor, and is pushed back towards the fan by the incoming hot air. So, when you turn on the air, the fan is just cirulating hot air, not making it colder. The air only becomes cooler when it flows away from the fan.
How is running ceiling fans instead using your air conditioner more efficient?
Since ceiling fans are much more simple than air conditioners, they require a lot less energy to run, meaning they cost a lot less. During the spring and early fall when the weather is still fairly warm, you can use your ceiling fans instead of using your air conditioner. The key is that you use your ceiling fan properly according to the season. During the summer, run the fan counterclockwise. This will blow air down on top of you, creating a gentle breeze that will not change the temperature in your home, but will make your home FEEL cooler. During the winter, run the fan clockwise. Since hot air rises above cool air, most of the warm air from your furnace will collect at the top of the ceiling in layers. Running the fan clockwise will blow the air up, swirling the layers around and making the lower parts of the rooms feel warmer.
