A major part of our country is quite hot during summer months and electric fans most commonly ceiling type, are invariably used in most of the places. In the residential sector fans are the largest end-use appliances. These electric fans are manufactured both in organized sector and in unorganized sector. The comparative testing of electric ceiling type fans is from the organized sector only.
On a warm day, the hot air rises and warms the upper levels. The fan blades move the air around, blending the interior temperatures so that the hot air does not accumulate in one level. While fans are often used to cool people, they do not actually cool air, but work by evaporative cooling of sweat and increased heat convection into the surrounding air due to the airflow from the fans. It helps circulate the cool air better. It also creates a breeze effect that makes the room feel cooler than it actually is.
Fans don't make a room cool they merely make you feel cooler. By moving air over your skin, a fan can lower your body temperature, but will do nothing for the heat inside a room. So if you're not in the room, you're just wasting energy by leaving the fan on.
The standard sizes of ceiling fans available are 900, 1050, 1200, 1400 & 1500 mm. The most commonly used fans are of 1200 mm size and testing will be limited to 1200 mm size only.
VOICE Society has undertaken comparative testing of 7-8 brands of ceiling Fan ( 1200 mm , 3 blade, non decorative) as per national standard in an independent, NABL accredited laboratory. The brands identified are Crompton, Usha,Havells, Luminous ,Bajaj,V Guard , Orient etc..
The test programme for Comparative Testing study is mainly based on relevant Indian Standard IS: 374. The important tests conducted were Air Delivery, Power consumption and service value etc.
The key test findings on quality and performance parameters are available in June, 2019 issue of “Consumer VOICE” magazine.
Please watch out for top performer brands as well as value for money.
