Are Bladeless Fans More Energy Efficient Than Regular Fans？

When we consider the choice of fans, apart from functionality and wind power, energy efficiency becomes a key factor that is gradually being taken into account by everyone. In this regard, bladeless fans are considered to be more energy efficient than conventional fans for the same amount of wind power. CROSSBOW as a manufacturer of bladeless fans will take you through the differences between the two types of fans and why bladeless fans are considered to be more energy efficient?

What is the Power Consumption of a Bladeless Fan?

Bladeless fans typically range from 15W-50W. Bladeless fans tend to be able to consume less power while providing the same amount of wind power due to their special design and technological advantage of using an aerodynamic source flow. Typically bladeless fans may run between a few watts and a dozen watts in low gears, and their brushless motors are more energy efficient than regular motors. Bladeless fans that use brushless motors usually have more air speed stops, allowing for more precise control of the air speed and less excess energy loss.

What is the Power Consumption of a Regular fan?

The power consumption of a conventional fan is generally between 40W and 100W. The power consumption of a conventional fan generally depends on the size of its fan blades, the larger the fan blades the more power it consumes. Because of their mechanical construction, conventional fans have relatively high losses during energy transport and transfer, and the motors used are usually brushed motors, which are less energy efficient than brushless motors. Therefore, under the same wind conditions, the power consumption of traditional fans is generally higher than that of bladeless fans.

Are Bladeless Fans Quieter?

Bladeless fans are known to be widely praised for their quiet operation, and because they use an internal impeller fan, they produce less wind noise than the sound of traditional fan blades slapping the air. However, it does produce some noise. Air passing through the internal ducts also creates some noise. If your bladeless fan is noisier than a traditional fan. Then you need to be aware that your bladeless fan may need to be repaired or replaced.

Bladeless fan VS Regular fan

Technical principle and mode of operation

Bladeless fans are driven by an aerodynamic working principle that drives the impeller motor, which is driven by a circuit board, which reduces mechanical friction and energy loss, so energy consumption is lower.

Conventional fans use rotating fan blades to drive airflow, which generates wind power and requires a larger power drive. And there is mechanical friction and energy loss of the commutator so the energy consumption is higher.

Motor efficiency and construction differences

Bladeless fans usually use brushless motors, which are able to achieve higher energy conversion efficiency, paired with a special design structure that utilises the principle of turbocharging, which uses less energy and produces more wind power.

Conventional fans usually use brushed motors without any special structural design, part of the energy is lost in the transmission, so it takes more energy to produce the same amount of airflow.

Air speed control and energy efficiency optimisation

Bladeless fans typically have a wider range of air speed settings, allowing for more precise control of airflow and energy savings at different air speeds depending on the user's needs.

Conventional fans typically have only three speeds - low, medium and high - which do not allow for precise control of air speeds and result in higher energy losses at higher speeds.

Structural design and technological innovation

Bladeless fans are often modern and innovatively designed, and energy efficiency is constantly being improved through iterative development of more efficient ways of transmitting wind power.

Traditional fans have been designed over a longer period of time and lack more modern energy-saving technologies and optimisation measures, resulting in lower energy efficiency.

Ways to reduce the power consumption of bladeless fans

1. Try not to place the bladeless fan next to furniture when using it, as this will block the air intake, resulting in less wind power.

2. Bladeless fans with air purifying features need to have their filters cleaned regularly, which will also increase your fan's efficiency.

3. Put it in the right place in the room, next to the window, or the door, it can promote the air circulation of the whole room, and improve the cooling effect of the whole room.

4.Use a bladeless fan with a timer function at night to reduce excessive energy waste.

5.Heating and cooling bladeless fan with automatic temperature mode on.
