The whole story of fans

Have you ever imagined our life without fans? Even after the invention of the air conditioner, the demand of the fans in India has never decreased. Now the question is, what are fans? Fans are the electronic devices that create flows in the air. Fans usually have blades. From ceiling to table fan, every kind of fan has blades, and the number of the blades varies. A fan impacts the air when the blades rotate and create a flow in the air. A fan can redirect the direction and the speed of the air. And the fan only does so because of the fast and rapid rotation of the blades. The fans have power sources to move the blades rapidly. Usually, most of the fans have electric motors as power sources. Some other kinds of fans have hydraulic motors and internal combustion engines.

Uses of fans

A fan is one of the most important electronic appliances in every house. You probably can’t find any house without a fan inside. As the electronic lights are important for regular survival, the fans are important too. Hence, fans have numerous uses. The regular people mostly use fans for controlling the climate, weather, and for providing personal thermal comfort to themselves. The motor manufacturers use fans as the engine coolers. This is also an important usage. Because the vehicle engines stop working sometimes and get crushed if not cooled. You can see fans as coolers inside devices like computers and generators.

You can also see the usage of fans on other devices too. Driers have little fans inside to dry down the wet clothes or hair. Vacuum cleaners also include fans inside for dust cleaning and other cleaning purposes.

But there is an amazing thing to know. A fan doesn’t cool your body itself. You might have a habit of coming from the heat of the outside and turning on the fan to cool down yourself. You might have always thought that the fan directly cools you down. That’s not facts. A fan has no direct impact on cooling you. It only cools you down indirectly. A fan induces the evaporative cooling of the sweat, and you feel cool. That’s why a fan doesn’t cool you properly when the surrounding air has much more humidity.

Types of fans

There are multiple types of fans there. The main materials of fans are plastic and metals. Here are some common types of fans-

Ceiling fans

This is the most common type of fan that you can see in every house. These fans get attached to the ceiling of a room and produce the airflow downwards. These fans don’t have blade guards, and these fans are usually big.

Table fans

These are comparatively small-sized fans. You can keep this kind of fan anywhere. These fans produce a parallel airflow. A table fan is capable of producing more airflow than the ceiling fans.

Exhaust fans and cooling fans

You can see the exhaust fans mainly in kitchens to exhaust the warm air outside. The cooling fans are used inside motors and several devices to cool the main motor or engine.

The survival of society is tough without fans, and we need fans every time to live in a better way.
