As Summer approaches, now is the perfect time to buy a new ceiling fan or upgrade your current system. Maintaining a fresh and cool surroundings is crucial for a comfortable Australian summer. To fight the unpleasant heat, you need a reliable ceiling fan. DC ceiling fans are flooding the Australian ceiling fan market. This is because they generally use less energy than other ceiling fans.
Outstanding energy efficiency, low maintenance, and ease of use are important features to consider when choosing a new ceiling fan. While ceiling fans may seem like simple devices, there are some design aspects you should consider when choosing the best option for you. This includes the type of motor. Today we are going to discuss what a DC fan is, what an AC fan, and which is the right choice
for you!
TECHNICAL ASPECTS
In general there are two types of ceiling fan motors – AC and DC.
AC MOTORS
AC or Alternating Current is an electrical current that reverses direction. Most household appliances and many ceiling fans use AC motors. AC is also the type of current distributed by most power companies. These AC motors function via a direct connection to a power source. In turn, this power source is what creates the moment of force required to rotate the rotor of the motor.
DC MOTORS
DC or Direct Current is an electrical current which only flows in one direction. In DC motors the direct power source (AC) connects to a transformer which converts the power to DC. This decreases the amount of power used by only using a direct current instead of an alternating one. The DC motor uses a system of magnets of opposing polarity to create the force needed to rotate the motor’s rotor.
PROS OF AC CEILING FANS
Traditionally, ceiling fans only featured AC motors because residential properties have AC power. This power is cheaper and easier to produce and supply electricity. This is why, when installing an AC ceiling fan, it can be as simple as plugging it into the power socket. AC-powered fan designs also allow companies to supply a variety of controller with their ceiling fans. These options include remote controls, chain switches, and wall panels.
AC ceiling fans are also cheaper as they are easier to produce and maintain, meaning they are often also easier to repair. Finally, AC fans used to be the most common ceiling fan type on the market, however the rise in DC ceiling fans means there are more options available.
CONS OF AC CEILING FANS
The speed at which AC motors spin depends largely on line frequency and the amplitude of the power source. This can make maintaining a certain speed a challenge. As a result, most AC fans only have 3 speed options. They can also be far noisier than DC ceiling fans.
PROS OF DC CEILING FANS
Unlike AC fans, DC ceiling fans are high energy-efficient. They consume up to 70% less power than AC ceiling fans. For example, while an AC fan may consume 100 watts, a DC fan may only require 30 watts for the same cooling result. DC powered ceiling fans are also far slimmer and more compact so they are sleeker and can be better integrated into your space. They are also constructed in a way that gives you more control over power consumption and rotating speed. DC ceiling fans generally have 7 speed options to ACs 3 speeds. Finally, DC ceiling fans are extremely quiet and produce far less noise during blade rotation.
DC ceiling fans, however, can be more expensive. DC ceiling fans only became widely available in 2016, though their popularity is growing. Manufacturing these fans, however, is still more expensive so you may pay more for a DC ceiling fan than an AC fan. However, thanks to their energy efficiency, you will save more money in the long run than an AC ceiling fan. Finally, while there are some exceptions, most DC ceiling fans only come with a remote controller.
DO I CHOOSE AN AC OR DC CEILING FAN?
How do you decide on which fan to use in your home? Unfortunately, there’s no black and white answer. Ultimately, it depends on your particular needs. If you are looking for a fan that is extremely quiet for bedrooms and loungeroom spaces, then you might want to choose a DC ceiling fan. Further, if you want an extremely efficient fan and energy efficient, DC fans are your best option. An AC ceiling fan might be a great option for outdoor spaces where noise won’t be an issue. All in all, however, both fans will keep your home comfortable and cool throughout the hot Australian summer!
