Considering the fact that only a little more than 24% of households in India own air conditioners or coolers, it is better to say that better air circulation is essential in the places where we live. However, we are often worried about the energy bill. There is
nothing wrong – as after air conditioners (if used), it is (cumulatively) the second biggest contributor to electricity bills of any household. Then, what is the way out for the common people?
As per a new report released by UnivDatos Markets Insights, the BLDC Fan Market is expected to grow at a CAGR of around 8% from 2022-2028. Earlier also, in Cooling India we talked about the growth potential of BLDC fans. This time, I would like to highlight some of the advantages of these fans.
Technically speaking, the Brushless DC (BLDC) fans also known as energy-saving fans are the type of ceiling fans that consume lower energy compared to their counterpart induction fans. The BLDC fans consist of the SMPS to convert the AC supply into a DC supply, a microcontroller to receive the input data, an inverter, and a motor.
As per Crompton Greaves Consumer Electricals Ltd., “An ordinary fan has an average power consumption of 70-80 Watts approximately. These fans do not have the power-saving technique. On the flip side, a BLDC fan consumes 25-40 Watts, which is an enormous difference between the two.” According to Sinox Power, “The typical induction-based fan would consume around 75 watts whereas a BLDC fan would consume about 30 watts. Unlike lights which are only used during nights, a fan is an appliance which runs most of the time if the ambient temperature is high with no regular airflow of cool air.” Accordingly, they say the yearly electricity consumption for a regular fan is 410.625 units, whereas the same for a BLDC fan is 164.25 units.
With presence of a permanent magnet in the rotor and absence of carbon brushes, BLDC fans themselves produce less heat. Obviously, they are the best to beat the heat.
