Fans are machines used in creating flow of air to an environment by using their fast rotating blades connected to a motor and this blades can either be housed in a cabin to regulate the flow of air and prevent external interference or just hang freely .
These types of revolving fans are either put on the walls, fixed on desks and chairs, hung on the ceiling, put on enclosed enclosures for cooling or others designed in smaller sizes for cooling systems like in laptops and computers.
Fans covert electrical energy to mechanical energy which makes the motor spin inducing rotational power to the blades which produces creates a breeze like condition that speeds up evaporation of the body making one feel cold.
Fans also utilize the principle of hot air raising and cold air which is heavy streaming down and through this the entire room is made free from warm air; this is achieved by fans pushing cold air downwards and through any ventilations though the rotation of its blades which in turn will create a free space attracting cold air mass from the outside environment.
Fans are not always used for cooling but also used in keeping the house warmth incases of winter or rainy seasons and this is achieved by setting the fan to rotate in clockwise direction which will push cold air up and warm air down.
Fans are a better choice when in need of cooling services in the house than air conditioners which should be kept running and might end up consuming a lot of electricity unlike fans which you will only put them on when in need of that cool revealing breeze and putting it off when you are done.
They help in improvement of airflow in houses like the laundry, bathrooms or kitchens whereby the ensure sufficient flow of air and forcing the dirty stale out and also improving the quality of the environment and also aid in prevention mold growth.
Learning institutions have armed themselves with all types of ceiling fans to increase air supply as some classes may contain large number of student which might not be able for the doors and windows to give adequate air circulation; overheating and stuffy air hinder scholastic success hence there is a need to have constant supply of cold and fresh air to make the learning environment comfortable.
As plants need cool comfortable environment to grow in, fans can be used to achieve this environment and improve growth.
