How do fans make you feel cooler?
So a fan does not cool the room at all. What a fan does is create a wind chill effect.
When weatherpeople talk about wind chill on a cold winter day, what they are referring to is how the wind increases convective heat loss for details on convection). By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat. The more evaporation, the cooler you feel.
In a cooling tower, air blows over water to create evaporative cooling, and this cooler water is used in the heat exchanger of, say, an air conditioner. A more direct form of evaporative cooling is often found in greenhouses, farmers' markets and chicken houses. In these kinds of systems, water flows over a mesh, and a fan blows air through the wet mesh into the building. Humid, cooler air is the result.
Fans are by far the most economical cooling option in terms of both purchase and running costs. Fans are cheap to buy and cost an average of two cents per hour to run.
Fans provide a cooling effect by moving air either around a room or a person. Fans do not reduce actual room temperatures or humidity levels.
The table below will help you choose the most appropriate fan to suit the size of the room you wish to cool:
Selecting the best fan size
Available in desk, box or pedestal models.
Can be suspended in rooms with high ceilings.
Air has mass and thermal capacity. It transfers energy. It can be compressed. When it's compressed, air transmits hydrostatic pressure. Although it has a rather low specific heat, compared to other fluids, air is the most commonly used medium for heat transfer. It is available everywhere on the surface of the planet.
Air is usually taken directly from the surrounding atmosphere and returned
to it with a revised thermal content. Materials or objects that are cooled or
warmed are almost always immersed in air. Even if another medium is used to
cool a heat source, the ultimate heat sink is still the atmosphere, and, even
in that case, the secondary heat transfer path to the atmosphere is usually
a moving air stream.
Air Flow Rates and Package Layout
In electronic equipment and circuits, power dissipation is generally a stated condition; an air flow rate requirement is dictated by the need to keep the temperature of one or more of the components within specified design limits.
