Mechanical fans were first invented in 1500 as frames which were covered as canvas known by the name of Punkah. These particular types of fans were fixed on the ceiling. For making the surrounding cool, there were ropes which were connected to them that were pulled by the servants.
Electric fans were available to the general public after electric power was introduced. Fans enhanced a home’s decor because they were functional and stylish and equipped with brass blades and cages. Mass production of modern electric fans was made possible by industrialization in the 1920s.
As the year 1960 approached the sale of these fans became low. The reason which led to this situation is the invention of the air conditioners. Soon, these fans again gained back their original position in the market and are commonly used in Asia and Europe.
The electric fans are always considered as supplementary for the purpose of spot cooling as they are energy efficient when compared with the refrigerated cooling technique given by the air conditioners. The other functions of this particular types of fans are ventilation, exhaustion etc. Axial, cross flow and centrifugal are the types of fan technologies that are used for the movement of air.
The method fans use for climate control and utilized to provide comfort or ventilation is axial flow. Air is forced to move parallel to the shaft by the blades while the blades rotate around it and blow across the axis of the fan. A couple of applications that use axial flows are personal cooling in personal desk fans and giant fans commonly found in wind tunnels.
An electric fan’s basic components include the base, fan blade, armature and lead wires, motor, blade guard, motor housing, and oscillator gearbox and oscillator shaft. The rating of an electric fan is determined by the types, size and number of blades. The materials from which the fan’s components are made determine the price.
