These are electronic powered machines which are used to create flow of air by use of blades connected to a motor inside it which propels the blades in direction clockwise or anticlockwise and some have their blades outside while others have blades in the inside of a case or housing which prevents contact with external objects.
Revolving blade fans are made in a wide range of designs and are used in on the floor, table and desk or hung on the ceiling and also some smaller designed fans are found on electronics for cooling the systems ,others are also installed in vehicle engines foe cooling the enclosed system.
Fans use a series of process to perform their work, they do this by converting the electrical energy to mechanical energy to enable the blades to rotate as the motor inside it is spinning, its through this spinning which causes rotation which in turns creates a breeze that speeds up evaporation of sweat in the human skin cooling the body.
Through rotation of the blades, hot air which is lighter than cold air will rise up and be pushed out towards any ventilation in the house which will leave spaces for the cold air to come in and occupy and if this process continues, the entire room is cooled.
Fans mostly the ceiling ones are important to a building as they can help both in cooling the house in hot times and also keep the house hot incases of winter depending on the setting of your fan and this helps in maintaining the conditions of the house at all times; heating fans should be set to rotate or turn in the clockwise direction and this maintains warm air down keeping the residents warmth.
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.
Fans can also be used in agricultural production where they can be used to help seedlings or even the grown plants have proper respiration and growth as they provide a cool comfortable environment.
