Ceiling fans are designed based on operating conditions of the environment of a particular place. In a hot and humid country like India, the central purpose of an electric fan is to create airflow and deliver a cooling effect.
So, what exactly do 4-5 bladed fans do? Do more blades increase the airflow? Are these better than three-bladed ones?
Let’s find out.
In India, ceiling fans are usually stand-alone appliances to generate cooling comfort in hot and humid weather conditions. Although air conditioners have gained traction in places with scorching temperatures, ceiling fans have not lost their importance even in today’s time.
As per experts, three-bladed fans deliver optimum performance when it comes to air movement and efficiency. With more blades, its performance does not necessarily get better, or the energy bills get reduced. More number of blades makes it worse by increasing the aerodynamic drag on the motor.
Technologically, the lesser number of blades generate more air delivery. This is one of the reasons why industrial fans (like wind turbines) usually only have two or three blades. They can go faster and move more air but are lot noisier.
So, three-bladed fans are ideal for domestic or commercial needs where fans need to be less noisy and where ample breeze outflow is needed. These are perfect for the Indian customers for giving optimum air delivery and cooling comfort.
With higher number of blades, a fan tends to be slower in speed and circulates less air but makes lesser noise too.
Aren’t 4 or 5-Bladed Fans suitable for Indian climate at all?No .. this is not entirely true. Looks wise, they appear to be very unique and classy – a status symbol in many elite homes. These have high aesthetic value with an ability of making lesser noise. These circulate gentle breeze which makes them suitable for rooms with air conditioners in India.
The 4 blade and 5 blade fans are costlier too. Buyers, who prefer such fans, generally do not give importance to the monetary factor; rather focus on specific needs of home decor. No matter how pricy are they, these have a separate consumer base who demands more than just circulating more air.
Why do people in the USA & Canada prefer 4/ 5-bladed ceiling fans?In the US and Canada, a ceiling fan is considered as one of the essential home appliances as well. Although, these are designed to circulate air for cooling but these are needed for more than their functional value in these countries.
In general, the fans sold in these countries come with a reversible switch . This helps to rotate fans in the opposite direction to absorb the air from below and circulate warm air around during cold days. This is how, such fans save energy by heating during winter days.
In some of the states of the USA using ceiling fans with reversible switch is mandatory for saving energy and money.
Also in these countries, as fans are considered a decorative element in homes, more number of blades is preferred. Most of the ceiling fans preferred in US and Canada come with light attachments as tube lights on walls are not used and uniform light emitting from centre of ceilings is preferred.
