The rapid development in technology has led to the improvement of many products such as cars, computers, and now ceiling fans. This advancement in technology has led to the introduction of DC motors into the market, giving people the option to invest in either AC or DC ceiling fans.
Like other products, both of the two ceiling fans have their own benefits and drawbacks. If you wonder which one to invest your money in, you first need to understand how they work and their advantages and disadvantages. To help you gain this knowledge, this article looks at each of the two ceiling fans more comprehensively.
Differences Between AC and DC Fans
The primary difference between DC and AC ceiling fans is in their operations. An AC ceiling fan makes use of alternating current (AC) to power its motor. The alternating current comes directly from your local power supplier. To control AC ceiling fans, you should regulate the power using a speed control device. This fan uses a capacitor that you can find behind the dial in the switch plate or in the remote's receiver.
On the other hand, a DC ceiling fan uses direct current (DC) to power its motor. This occurs through an AC to DC converter integrated into the ceiling fan. It converts the standard AC power to DC and controls the ceiling fan at a lower voltage.
As you can see, DC and AC ceiling fans are distinguished by the current they use. AC fans are powered by an electrical charge featuring a reverse flow direction, while DC fans work with constant flow.
Pros of DC Ceiling Fans
Energy Saving
DC ceiling fans feature 35w motors. They also have a power breakdown of 35w, 22w, 14w, 8.5w and 5.5w. This means that the DC fans can save you 70 per cent of the power consumed.
Produce Low Noise
These fans produce little or no noise from the motor compared to the conventional AC fans. DC fans only produce a sound when starting, but the sound reduces due to the low voltage involved in its operation. The quietness also results from the fact that there is little electromagnetic interference. There is no alternation of frequencies, so the motor produces no noise.
Reliable
Since DC fans operate with lower voltages and reduced electromagnetic interference, this means they are more reliable. The fans can last for more than fifteen years without breaking down. On the other hand, AC fans run with a high-level voltage and are regulated through small capacitors that risk breaking down after around ten years.
Highly Functional
DC ceiling fans feature a wide range of speed options. You can get the fans with five to six-speed settings or even seven. The speed settings are more compared to AC ceiling fans that have just three settings. DC fans also come with a winter/summer option on their remote. This is unlike AC fans that need a manual button located on the motor to reverse the direction.
Moreover, DC fans feature a sea breeze technology that fluctuates with various speed settings bringing a good wind breeze effect. This feature is not available to AC fans.
Compact Design
DC fans have compact motors compared to the larger AC motors. This gives DC ceiling fans a more modern or sleek design. Together with the latest blade material composites, DC fans have more elegant designs than their counterparts.
Cons of DC Ceiling Fans
Expensive to Purchase
These fans are costlier than AC fans. Thus, if you are working on a small budget, you cannot buy one for your household. However, the high initial costs pay back in the long end because the fans are more energy-efficient and long-lasting than the AC ceiling fans.
Need a Transformer to Operate
DC ceiling fans use direct current, meaning that the current only flows in one direction. Simply put, these fans cannot directly connect to an AC power source such as batteries or Adelaide solar panels. These fans require a transformer to change AC to DC to power them.
Pros of AC Ceiling Fans
Cheaper to Buy
AC fans tend to be cheaper than DC fans. Therefore, you can go for this option if you are working on a tight budget. You can get them in a wide variety of styles. Simply put, you can get the style that you want at a friendly price.
These fans are also easier to maintain compared to DC fans. When you invest in AC fans, you do not worry about sudden repairs that can affect your budget.
Flexible Control
You can control AC fans from a pull cord, wall control, or a remote, unlike DC ceiling fans, which you can only control using a remote. This can cause a lot of inconveniences if you happen to lose your remote. The remote may also be broken or run out of batteries. DC fans with a wall controller option come with extra costs.
Energy Efficient
Even though AC fans are not as energy-efficient as DC fans, they use less energy than most other home appliances. Typically, a standard model usually uses less than about one hundred watts.
Cons of AC Ceiling Fans
Difficult Speed Control
Controlling the speed of AC fans is not easy. The speed is determined by the line frequency and partly the AC voltage source amplitude. Due to its high conversion costs, it is not practical to change the AC voltage frequency. It is also costly to change the amplitude and maintain the AC voltage source waveform.
Consume More Energy
AC fans use more energy compared to DC fans. Despite the fact that AC fans initially cost less, you may spend more in the long end through high power costs.
Produce Noise When Running
AC fans usually have more electromagnetic interference than DC ceiling fans when using the phase control methods. This results in the fan producing noise when running, unlike DC fans which do not make noise. This noise can prove to be annoying, especially if you enjoy silence while relaxing.
DC Fans vs AC Fans - Which is Better?
Based on the information provided above, you now have a better understanding of AC and DC ceiling fans. You can determine the fan that you want to install on your property. If you are wondering which fan is better than the other, read on.
To answer this question, neither fan can be termed to be better than the other. The best fan for you depends on your household’s specific preferences and needs. For instance, DC ceiling fans will do if you want a quiet ceiling fan that provides good air movement and saves energy. On the other hand, if you intend to invest in a cheaper fan that offers more flexibility in control, an AC ceiling fan is the best option.
You should not avoid AC fans just because of their high energy usage. They may consume more energy than DC fans; however, they do not use as much energy as other household items. All in all, the two types of ceiling fans perform an excellent job of keeping your space more comfortable temperature-wise. The most important thing is to keep an eye on are the many features and costs tied to both fans to make an informed choice.
Still Unsure of which Fan to Buy?
If you are still unsure whether to go for an AC or DC fan, you can ask for professional help. Depending on your needs and other circumstances, the best ceiling fan companies can advise you on the best fan to buy for your household. Most professionals have many years of experience in the industry, so they can offer you more reliable advice and allow you to invest your money wisely.
With the assistance of a local electrical professional or ceiling fan installer, you can quickly transform your space into a grand haven to relax and work in, owing to the well-controlled temperatures. Besides helping you choose the ideal ceiling fan, they also help with high-quality installation services to ensure high-level efficiency and durability.
