What Is Dual Inverter Air Conditioner

What Is A Dual Inverter Air Conditioner & Its Pros And Cons

Air conditioners are well-known energy-sucking monsters. While we want to enjoy the bliss of a powerful air conditioner on hot summer days, we don’t want to pay the high energy bills that come with it.

Manufacturers strive to improve their products’ energy efficiency and comfort, and the dual inverter air conditioner is one of the most advanced models they have created.

If you’re unfamiliar with this new type of air conditioner, you’ve come to the right place. I’ll go over all of the fundamentals you need to know about it so you can decide if it’s a good fit for you.

What is a dual inverter air conditioner?

The dual inverter air conditioner is an advanced version of a simple inverter air conditioner. It can automatically adjust the rotor speed and tonnage based on the room temperature by utilizing a twin rotary compressor with two compression chambers.

Dual inverter air conditioners are more energy-efficient and quieter, making them a popular choice in the market.

Dual inverter AC vs. inverter AC, what is the difference?

Since a dual inverter AC is an upgraded version of a regular inverter AC, it should have some advantages. 

But before we jump into the comparison between these two, let’s first discuss what an inverter AC is. After all, not many people know much about it either.

A non-inverter air conditioner can only operate at full capacity or turn off. When the preset temperature is reached, the compressor will turn off and restart when the temperature in the room rises or falls to a certain level.

Because the compressor will consume a lot of electricity when starting, it will leave impressive numbers on your electricity bills.

An inverter AC is a big step forward. Featuring inverter technology, it can control the speed of the compressor by controlling the current to the compressor. That is to say, this type of AC will run at a low speed after the room is cool or warm.

Because your air conditioner will not be turned on and off repeatedly, it will use less energy than a standard unit.

Similarities

A dual inverter AC, like a simple inverter AC, uses inverter technology to adjust the output via a variable speed compressor. It will not turn off during operation so it can save energy and reduce noise.

Differences

However, a simple inverter AC only has one rotor in the compressor, whereas a dual inverter unit has two. Each of them is in one compressor chamber.

These two rotors turn with a 180-degree phase difference in order to offer a more stable, balanced, and efficient operation. The torque variation is reduced.

Aside from that, when dealing with the same load, having two rotors instead of one allows the compressor to work faster and more efficiently.

Therefore, you can expect a dual inverter AC to be quieter, more durable, and more effective than a single inverter AC. However, because of the advanced technology, you need to shell out more money for it.

Benefits of using a dual inverter air conditioner

If you feel a bit daunted after reading the technical details I mentioned above, you can have a more clear idea by exploring the benefits of a dual inverter AC in this section.

Save a lot of electricity 

Due to the use of a twin rotary compressor, dual inverter ACs can adjust the rotor speed according to the room temperature and keep running at a low level when the room is cool. 

The two rotors also allow it to remove more heat while not operating at full capacity.

As a result, it consumes significantly less energy than a non-inverter unit and saves approximately 20% more than a single inverter unit.

Faster cooling

If you don’t keep the air conditioner running all day, you’ll have to wait a while after a long day of hard work before your room cools down. Some people may find this frustrating.

Dual inverter air conditioners provide faster cooling because their compressor is extremely powerful and can handle a large amount of heat in a short period of time. The two rotors are crucial in accomplishing this.

Last longer 

The compressor is the heart of an air conditioning unit. If it often works at full capacity, it will wear out very soon. 

Because dual inverter air conditioners have two rotors, it doesn’t need to run at an extremely high speed to remove the heat, it will experience much less tear and wear. As a result, it will have a longer lifespan. 

Quiet operation

When a compressor is in use, it vibrates and makes noise. Because of the two rotors in the compressor, vibration has been greatly reduced, providing you with the quiet environment you desire.. 

If you really concern about the noise level, this type of AC will take the win in this round. 

Disadvantages of using a dual inverter air conditioner

To be honest, I don’t see any significant disadvantages to dual inverter air conditioners, but there are some potential drawbacks to consider.

High product price 

Dual inverter air conditioners, like any product equipped with cutting-edge technology, are more expensive than their competitors.

While it will cost you more money up front, it will pay for itself in energy savings within two years, making it a good investment.

High installation fee

Yes, you need to pay for the advanced technology when installing it as well. Dual inverter air conditioners require a more skilled HVAC technician due to their complicated mechanism.

High repair cost 

Even though a dual inverter air conditioner has a longer lifespan, some components may fail at some point. They may need to be repaired or replaced. However, these replacements may be costly.

Which brands make dual inverter air conditioners?

Not every well-known brand manufactures dual inverter air conditioners. Some brands just don’t focus on innovation. 

Famous brands that make dual inverter AC units include LG, Midea, Hisense, Haier, Whirlpool, Senville, and Hitachi.

Recap

Thank you so much for sticking with me all the way to the end. Hopefully, this guide has helped you to figure out what a dual inverter air conditioner is.

The dual inverter AC features a twin rotary compressor so that it can adjust the speed precisely according to the room temperature. Meanwhile, it can remove heat much easier.

While it may cost more up front, you will benefit from a quieter, more efficient, and longer-lasting air conditioner in the long run.
