What is a Dual Inverter Air Conditioner? [Benefits & Disadvantages]

Without even giving it much thought, energy consumption might just be the biggest disadvantage of owning an air conditioner. But what if that doesn’t have to be the case? Compressors are often regarded as the heart of any AC unit.

Without a functioning compressor, the air conditioner cannot carry out its cooling feature, and producing even a single gust of cool air would be near impossible.

Compressors work mainly by compressing the air conditioner refrigerant and distributing it around the air conditioning system. Much like the heart pumping blood throughout the body, compressors are very vital in distributing refrigerants and expelling heat.

With significant advancements in technology over the years, there has been a significant leap in air conditioner technology in the form of Inverter technology.

This may just be the greatest innovation in ACs in recent years, as it has completely changed how we view compressors.

Inverter technology can alter the speed of compressors using unique BLDC motors. It means with this technology in place, the speed of compressors can change depending on your cooling requirements.

Think of it as an accelerator in your favorite car. When the compressors require more power to cool faster, the inverters give it such power and when it requires less power, the inverter also responds appropriately.

The major advantage of this is in energy efficiency, and in getting the precise cooling effect needed per time. There are different types of inverter compressors currently available on the market, but for the sake of this post, we will focus on the Dual Inverter.

What is a Dual inverter air conditioner?

Technology is constantly improving to be able to serve your needs more accurately. An upgrade to the inverter technology is the dual inverter air conditioners which utilize two rotary compressors in place of just one.

Imagine this scenario, you are in your living room relaxing with your air conditioner on.

If you are using the ordinary inverter air conditioner and the highest temperature and its limit is 18 degrees, the air conditioner kicks off operating at 14 degrees if the lowest temperature is 14 degrees, and when it gets to 18 degrees, it is immediately cut off.

And when the temperature in the environment increases, the entire process is repeated. This entire process consumes so much power at the full rate.

On the other hand, with dual inverter air conditioners, the temperature is regulated to the desired level with significantly less power consumed.

How does a Dual Inverter Air Conditioner work?

Dual inverter air conditioners are more advanced and efficient than single inverter air conditioners. But what exactly makes the dual inverter that much special?

First, The BLDC motor utilized in the dual inverter is more advanced and more powerful than the one in the single inverter air conditioner.

With this special motor, dual inverter air conditioners have a range of better operations and more precise cooling than ordinary inverter air conditioners.

Nobody wants a noisy air conditioner, and this is one of the main reasons single inverter air conditioners needed an upgrade. They operated using a single rotary compressor to provide different speeds.

While this may have worked, the noise and vibrations it generated in the process was unbearable. The excess noise was as a result of the whirling of the shaft while running at full capacity.

Then came dual inverter air conditioners that utilized the double rotary compressor design which involves two rotary compressors that function with a 180° phase difference in the timing of their mutual compression which leads to a more coordinated and balanced operation.

Apart from significantly improving rotational balance, dual rotary compressors also boost the compression torque, ensuring that working from a mere 700 RPM to about 8000 RPM is possible.

This is the reason why variable tonnage in dual inverter air conditioners is very attainable. Speaking practically, a 1.5 ton AC equipped with double rotary inverter technology can change its tonnage from 0.3 ton to as impressively high as 1.8 ton.

Advantages of Dual inverter Air conditioner

The benefits of dual inverter ACs are more apparent in their usage. Dual inverter air conditioner users often testify to significant benefits with regards to faster and more precise cooling, less noise and vibrations, and energy efficiency.

Dual inverter air conditioners are able to cool faster as a result of accurate precision in controlling temperature. External demand placed on the air conditioner is the main determinant for its varied rotor speeds.

To be able to achieve a quicker cooling time, your unit doesn’t need to run at full capacity.

With dual inverter ACs, double rotators that are responsible for variable tonnage during the process of expelling heat from the room are deployed efficiently. This makes attaining the perfect room temperature a lot faster than when you use ordinary single inverter air conditioners.

The less vibration there is, the less noisy your air conditioner will be during operation. In previous single inverter air conditioner models, the rotor moves at high speeds, which in turn produces more noise as a result of increased vibrations.

In a dual inverter air conditioner, however, the rotors move at a 180° phase angle, which makes it a lot more stable when it runs at its highest capacity. This produces way fewer vibrations and as a result less noise.

Just in case you’re cost conscious, the dual inverter air conditioner’s energy efficiency ensures you spend less running the air conditioner in your home.

Some top air conditioner brands claim you can save up to 53% in cost using dual inverter air conditioners that consume way less energy.

Disadvantages of Dual Inverter Air conditioners

Although there are several benefits you will enjoy when you opt for the dual inverter air conditioners, there are still a few things to be wary of.

For instance, the installation process of the dual inverter AC may be a little cumbersome and should be reserved for only competent AC technicians.

Several popular brands did not include Amazon Alexa compatibility to the air conditioners in this category.
