BLDC ceiling fans are marketed based only on their power consumption. But the power consumption depends on various other parameters, size, airflow, speed to name a few. Especially the ’28 W‘ is being used in the market a lot, is it true? Can a BLDC ceiling fan consume 28W or lesser? There could be two possibilities: 1. It could be a marketing gimmick of expressing the specification of the BLDC ceiling fan in a clever way to deceive. One step…
Is the ceiling fan you buy, fair to you and everybody else? Superfan makes ceiling fans that strive to be fair to the consumers, the nation, and the environment. CUSTOMERS Sensible Innovation Ceiling fans earlier were negligent about power consumption, contributing to expensive electricity bills and pollution due to electricity generation, Superfan broke this stereotype in 2012 by inventing India’s first super energy efficient ceiling fans. This innovation replaced the inefficient AC induction motor of ceiling fans with Brush-Less Direct…
The function of a regulator is to provide the user with control over the fan. This control comes with a loss of power. Therefore, it is good to choose the type of regulator that minimizes this loss (To know more read: What does a fan regulator do? ). Regulators also save energy as the user can operate the fan at the desired RPM, which may be lower than the highest RPM in many instances. Currently, capacitive-based regulators are the best…
Regulators, as the name suggests, regulate or control the speed of the fan motor. They have been around since the 1950s, and there are a few types of them. Resistive regulator These are the box type regulators, found in many old building and homes. It has a wire wound resistor with different contact points as the speed positions, with each contact point corresponding to a resistance value. The presence of resistance reduces the voltage supplied to the fan. In an AC induction motor,…
Government of India through the Ministry of Power operates an agency called Bureau of Energy Efficiency (BEE) that assigns energy efficiency rating to appliances that are participating. The efficiency is rated in a star-based system, with ‘5 stars’ indicating the most efficient and ‘1 star’ the least efficient. BEE formulates an efficiency parameter and its required value for each appliance. Many of us are familiar with the star rating in ACs & refrigerators. Recently, it was ruled that from Jan…
Ceiling fans are the primary space cooling appliance in India. Ceiling fans may seem like a simple concept, but like everything else in the world, there are misconceptions and myths. Here are some common misconceptions and myths about ceiling fans. Ceiling Fans Cool The Room No! Ceiling fans don’t alter room temperature. It promotes air circulation and has no control over room temperature. The chillness we feel when under a ceiling fan is because it escalates the evaporation of our…
Superfan’s patented original design has brought numerous innovations to a stagnant Indian ceiling fan industry. The following are a select few that shows why Superfan is ‘Fan reinvented’. Super Energy Efficient Ceiling Fan (35 W) Superfan broke the 35W barrier to enable an Indian ceiling fan to enter the super energy-efficient category of appliances. This novel design has been awarded two patents (2873/CHE/2009 and 3505/CHE/2012). Sensor-less BLDC control One of the challenges in BLDC technology was to minimize the failures…
Regular old ceiling fans Ceiling fans escape one’s mind when thinking about reducing electricity cost. This forgotten appliance contributes significantly to electricity consumption due to its numbers and hours of usage. The following estimation supports this claim. A regular ceiling fan (1200 mm span) consumes about 75 W at the highest speed. There are over 400 million regular ceiling fans in India and each of them creates an electricity demand about 39W* (consumption at medium speed). Super energy efficient ceiling…
