Wouldn't it be a huge burden for people if air conditioners had never been invented? In case you're planning to get your first air conditioner and are torn between an alternating current (AC) and a direct current (DC) air conditioner, we gathered information from experts to help you decide!

Although AC units have been popular for years, DC air conditioners are found to have more advantages compared to AC air conditioners, making them more popular and better known on the market. DC air conditioners are more energy-efficient compared to mainstream AC air conditioners.

A DC air conditioner is power-saving, can last longer, and produces less noise compared to an AC-powered air conditioner. However, DC air conditioners may require you to have an AC to DC power supply since it's powered by direct current.

The downside of using a DC air conditioner is that you have to install a power converter called a rectifier that converts AC voltage, which we mostly use, and turns it into an optimized DC voltage to power up a DC air conditioner. You might want to consider this before choosing between an AC and a DC air conditioner, so keep reading this post to find out more!

AC Vs DC Air Conditioner: Which To Choose?

Whether it is your first time purchasing an air conditioner or you're thinking of switching to a different type because your current air conditioner makes a lot of noise and doesn't cool down the room enough, it is important to first understand the options available. 

We often see the box-type air conditioners installed in closed areas, mostly built through a wall. The most common type uses an alternating current power supply to power it up.

However, due to the increase in the popularity of alternative energy source such as solar energy, direct current-powered appliances began to hit the mainstream. One of these is a DC air conditioner, commonly known as an inverter air conditioner.

When choosing between an AC and a DC air conditioner, you must first understand the advantages and disadvantages, how they work, and the difference between the two in order to know which type of air conditioner will suit you best.

Below are the factors you might want to consider before deciding:

Difference between AC and DC Air Conditioners

AC and DC air conditioners have a lot in common in terms of their functions. Understanding the following will help you decide whether to stick with a more common AC air conditioner or switch to a DC air conditioner.

Type of Current

The main difference between an AC and a DC air conditioner is the type of energy they use in order to work.

AC air conditioners use an alternating current to power up. An alternating current is a type of electric charge that periodically reverses at a specific interval. It is the most typical type of energy that households consume for energy-powered appliances. 

On the other hand, DC air conditioners function by using a direct current as an energy source. A direct current is a type of electric current that only flows in one direction.

An example of this is solar-power energy. This is why a DC air conditioner needs to have a rectifier in order for to work.

Although it is not possible to directly use an alternating current to power up a DC air conditioner, some air conditioners nowadays use a system that allows it to convert alternating current and invert it, resulting in less energy consumption while promoting better performance. 

Power Consumption

Since huge energy consumption is one of the major problems nowadays, many people are switching to appliances that consume less electricity.

A regular 1.5-ton air conditioner that's fueled by alternating current use about 2000 watts of power, while a 1.5-ton DC air conditioner only consumes about 1200 watts of power. 

How Does a DC Air Conditioner Work?

While an AC air conditioner can easily function by plugging it into an alternating current power supply, a DC uses an alternating current as an initial input, then converts and inverts it into a direct current power in order for it to work.

Right after the current conversion, the direct current flows smoothly to power up the other parts of the system, especially the rotor, with minimal current noise compared to a regular AC air conditioner.

Once the current goes through the circuit, a technique called pulse width modulation is used to convert back the direct current into an alternate current in order for the electricity to flow back to the source.

The process of switching the current from AC to DC makes the induction motor and the brushless motor run the DC air conditioner. 

What Are The Advantages and Disadvantages of AC and DC Air Conditioners?

Besides the differences between an AC air conditioner and a DC air conditioner, just like other appliances we use, these two have their own advantages and disadvantages. 

Advantages of Using an AC Air Conditioner

Since most households use an alternating current power supply, it is less likely that you will have trouble installing an AC air conditioner.

You will not need a rectifier to convert the current for it to work, unlike a DC air conditioner that seems to be a little more complicated.

Another advantage of using an AC air conditioner is that it's easier to generate, and there is little to no energy loss during the current circulation from the power supply to the AC circuit.

Most technicians are also more knowledgeable in fixing and maintaining an AC-powered air conditioner, so finding one wouldn't be much of a problem.

Disadvantages of Using an AC Air Conditioner

The downside of using an AC air conditioner is that it consumes more electricity compared to a DC air conditioner.

Other than that, an AC air conditioner has an attractive shock, unlike a DC air conditioner that has a repulsive shock, making it more dangerous to work when high voltage is involved. 

Advantages of Using a DC Air Conditioner

One reason why a DC air conditioner is becoming popular is that it uses less energy compared to an AC air conditioner.

It is also known for keeping a stable room temperature. Since it uses a direct current, there is no voltage shifting when used even in large closed areas. 

In addition to that, a DC air conditioner also produces less noise and is very efficient in cooling the room without using too much electricity.

Disadvantages of Using a DC Air Conditioner

A DC air conditioner has a higher price tag compared to a regular AC air conditioner, despite its less power consumption.

Another thing is the circuit used in a DC air conditioner is more complex compared to an AC air conditioner, due to the conversion process from AC to DC, which isn't part of an AC air conditioner's circuit.

Since a DC air conditioner is still new on the market, it is a little harder to find a technician to fix it once it breaks down.

Whether you're planning to get the typical AC air conditioner or you would like to jump on the DC air conditioner trend to lessen your utility bill, it is still important to put into consideration what's best for your home.

Make sure that before making the purchase, you can pinpoint the differences between an AC and DC air conditioner, their advantages and disadvantages, and how they work so you don't have any serious problems when using them. At the end of the day, what's more important is a safe and cozy home.
