Electronic gadgets have successfully made human life comfortable in multifarious ways. We use a variety of gadgets to improve the quality of life in one or the other senses. As the average global temperature of Earth is increasing, the summers in the tropics are getting hotter. In such a scenario, demand for quality air conditioners is on the rise.
The Dual Inverter Air Conditioner, also known as Twin rotary compressor AC, is an advanced form of inverter air conditioning with two rotary compressors and two compression chambers. It provides faster cooling, reduced noise levels, high energy savings, and shorter wait time with greater stability.
Before we dive deep into the dual inverter AC, let us first look into some facts about air conditioners. The world’s first AC dates back to 1902. It was invented by Willis Haviland Carrier an engineer from Brooklyn, New York. It was a simple barebone structure.
In this air conditioning apparatus, hot air was made to pass through coils filled with cool water. Consequently, the humidity was removed, and the air was rendered cool.
Today, the world has come a far way. Even though the foundational mechanism of present-day ACs remains the same. Yet, many advancements have come into effect. Electronic gadget technology took a great leap from regular to inverter AC to dual and even triple inverter AC.
If you are making your mind to bring an AC home, you must know about the latest technology in the market to decide better.
Presently, the most sustainable, affordable, and durable AC among all is dual inverter AC.

What is a Normal and Inverter AC?
Let’s start from the basics. Before we understand differences among various AC categories, let’s first know about its core elements.
Refrigerant
Refrigerant is an entity found in several electric appliances that absorb heat. It is widely used in refrigerators as well. Refrigerant runs inside the different parts of an AC and acts as a coolant.
Refrigerant is the medium or the actual carrier of heat and performs the exchange between the external environment and internal parts of an Air Conditioner.
Compressor
An air conditioner compressor is a mechanical device that compresses and forces gas into an air conditioning system, which makes the cool air in your home.
Air Conditioners are incorporated with electric motors, which supply energy to compressors. As the name indicates, the compressor ‘compresses’ refrigerant. Upon compression, the heat-soaked refrigerant is pressurized to decrease volume.
Air conditioner compressors are made out of metals that tend to resist heat and corrosion.
There are several types of air conditioner compressors available on the market. The scroll compressor is the most common type because it helps reduce noise. The piston compressor works well in a sealed environment with little available airflow, but it is louder than the scroll compressor.
The rotary compressor is the most efficient and helps to cool a home quickly, but it is also the noisiest of the three types of compressors.
Before purchasing an air conditioner, consider how much noise the compressor will make and whether it is necessary to have a silent machine. Most compressors produce loud noise as they run, but some are quieter than others. Decide how much of an issue this is before making a decision on which one to buy.

Condenser
The next element is a condenser. The condenser cools the superheated refrigerant as it passes over condenser coils.
After being condensed, the refrigerant releases the heat to external surroundings, the room temperature falls, and it returns to bring more heat from indoors.
A brief Working of an Air Conditioner
By now, we know that an Air Conditioner comprises three key components-
- Evaporation apparatus
- Compressor
- Condenser apparatus
The evaporation apparatus faces indoors, towards the room or hall. It is incorporated with a liquid refrigerant. The refrigerant absorbs warm air and turns it into a gas.
Now, the compressor poses high pressure on the gaseous refrigerant to decrease its volume. These hot and high-pressure vapors of refrigerant are sent to the condenser apparatus.
Here, cooling occurs. Condenser faces outdoors. It cools down the refrigerant and transforms it to a liquid state again. This liquefied refrigerant is sent back to the evaporation apparatus to absorb warm air again.
This cycle continues till the temperature status matches your preference. At that point, a thermostat in ACs automatically turns off the working. The cycle restarts as soon as the temperature starts rising again.
For more information on the different parts of an air conditioner and its working, refer to our comprehensive guide on the working of an air conditioner.
What is a Non-inverter or Regular AC
A non-inverter air conditioner unit has a fixed-speed compressor and a non-variable electrical supply voltage, which means that it does not have the ability to adjust the compressor speed given varying load conditions.
It is also known as a normal or regular air conditioner, and it uses an old technology of fixed-speed compressors. A regular air conditioner delivers fixed electrical supply voltage to a non-inverter AC compressor.
There is no reduced speed at partial load as would happen with the variable speed compressor in an inverter or non-inverter ac unit.
Thus, it does not have the convenience of changing the cooling capacity according to room size and it might not be as energy-efficient as an inverter ac unit, but they are more affordable and easier to use.
What is an Inverter AC
Normal non-inverter ACs sustained certain drawbacks such as noisy operation, less energy efficiency, uneven cooling, less comfortable, etc. Therefore, engineers redesigned the next generation of ACs to overcome the drawbacks residing in the previous AC version. For this, a few tweaks were made to the mode of operation.
An inverter air conditioner is a type of air conditioner that varies the compressor speed in order to maintain the desired temperature. This results in energy savings because the compressor doesn’t have to work as hard to maintain the temperature.
It is a powerful, yet energy-efficient machine that can regulate refrigerant flow and provide just the right amount of cooling or heating needed. It is known for its superior, sophisticated technology and is quite complex to understand but the crux of this technology is the variable speed compressor.
The compressors in Inverter ACs are powered by BLDC (Brush Less Direct Current) motors. These motors have the ability to keep the compressor in working mode continuously.
An inverter AC does not have frequent start/stop cycles like traditional AC units. It’s able to regulate its own operation so that it doesn’t overheat or shut down due to too high temperatures, but instead keeps running at optimal levels even if things get dicey outside!
Inverter air conditioners are also known for their ability to cool or heat a space quickly.
Normal vs. Inverter AC – The Difference
The significant difference between normal and Inverter AC lies in the mode of working.
Normal ACs have single peak power at which they work. But Inverter ACs work within a variable range of power which can be lower than the peak power value.
Unlike normal ACs, which stop working after attaining peak power, inverter ACs auto-adjust the power and keep working without switching off (until you do so).
For instance, after attaining the desired temperature of 20 degrees, the standard AC will stop working. As the temperature rises to 22 degrees, it will start again. This restarting of the AC motor requires a large amount of electricity, raising your bills.
On the other hand, inverter ACs don’t stop working after attaining 20 degrees Celsius temperature. They slow down the speed to draw minimum power, and when the temperature seems to rise, they increase their speed.
This way, the motor is always on, but much less electricity is consumed as compared to the case of restart.
What is Dual Inverter AC Technology?
You might have come across advertisements by some big brands marketing dual Inverter ACs with claims like cost-saving, faster cooling, longer lifespan, and so on.
These claims sound too good to be true. However, dual inverter technology is indeed a game-changer and offers several benefits to consumers. This technology uses two compressors instead of one. These compressors are set to operate at a phase difference of 180 degrees.
The compressors in dual inverter ACs are powered by more advanced BLDC motors that enable these ACs to have variable power consumption and continuous working.
The presence of the BLDC motor in dual Inverter AC will offer a better working mechanism than the usual compressor by having an extensive frequency range. This compressor also manages the production of vibrations and noise while the AC is in operation.
How Dual Inverter AC Work?
The twin compressors maintain a phase difference of 180 degrees in terms of compression timing. This ensures the stable operation of the AC. This stability further becomes the reason for enhanced durability and a longer lifespan of dual Inverter ACs.
Variable tonnage trait is another admirable thing about these ACs. Tonnage is the power consumed to remove an amount of heat per hour. The more the tonnage, the more is the energy drained.
With twin compressor ACs, the power consumed is less depending upon how hot the room is. For instance, if AC is labeled with maximum tonnage as 8 tons. It will work at 5 tons if the room is small and the heat load is less.
Contrary to this, a regular would work at 8 tons always irrespective of the heat load. It lacks auto-adjustment for power consumption. So, this is where you will be saving on electricity costs.
What is Smart Dual Inverter AC?
There are different types of dual inverters available in the market. Some of them are smart, and others are not. So what’s a “smart dual inverter ac”?
It means a dual inverter AC has sensors inside, such as temperature probes or humidity monitors, so they can automatically adjust themselves based on conditions outside.
Smart dual inverter ACs can also be controlled remotely using a smartphone or other device, allowing you to turn them off when not in use without having to get up from your chair!

What could be better than this?
Dual Inverter AC vs Inverter AC
Inverters are excellent inventions made to magnify the efficacy of AC. It is one of the best ways to optimize power savings when using AC. The Inverters make the compressor capable of running at different speed levels according to the temperature range you want the AC to function.
With the use of the Inverter technology, the compressor will always be kept on. Still, the power consumption will be limited based on the level of degrees in the thermostat and also based on the degrees of the air incoming.
With the Inverter, the speed and power of the compressor are balanced and appropriately adjusted. The most noteworthy highlights of the inverter AC are that it delivers a meager operating speed, which is critical for maintaining.
The maintenance costs are usually higher. You can find the inverter mechanism in both the Spilt AC as well as Window AC. The Dual Inverter ACs are much better at work when compared to the normal Inverter ACs. The motor present in the dual Inverter ACs is very advanced and offers the best functions.
The alignment of the motors balances compressional torque, by which the appliance is significantly stabilized. The frequency range of the motors varies between 700 to 8000rpm. The 1.5-ton Dual inverter AC can perform like the 1.8-ton of normal Inverter AC.
According to the principle, the compressor motor present in the standard inverter AC can perform only a single compressing rotation. This will, in turn, give out more noise and create higher vibrations.
More stable working is rendered from the functioning of two compressors, which are operated at a phase difference of 180 degrees. 2X efficient motors are present in the dual Inverter ACs when compared to the normal ones. Better temperature control is offered by the Dual Inverter ACs, and they are the best option for energy saving.
It also has the capacity of saving energy up to 830 units. With the more stable functioning of Dual Inverter ACs, the noise generated from it is very minimal.
Dual Inverter AC vs. Triple Inverter AC
Integrated with three motors, as its name suggests, the Triple Inverter AC operates on a unique mechanism. It runs on the eight-pole Triple Inverter technology.
The efficacy of instant cooling is much higher on a scale of 68 percent when compared to several other air conditioners. The energy-saving options are also thrice efficient when compared to the regular variants.
A triple inverter AC was first introduced by Samsung in 2019.
The overall working performance of the system is enhanced by the introduction of the four poles present in the compressor. The temperature is maintained in accordance with the room temperature, which doesn’t require frequent on/off, so power saving is guaranteed.
It comes with a faster cooling mode technology, making the compressor run at a much greater speed for the first thirty minutes. The presence of power boost technology looks into the torque vibrations, so the noise production is null.
Does Dual Inverter AC Really Save Electricity?
Dual inverter air conditioners are becoming more and more popular, and for good reason – they offer a number of benefits over traditional air conditioners. But one question that often comes up is whether or not they really save electricity.
The answer is yes, dual inverter ACs can save you a significant amount of money on your energy bill. How much depends on a number of factors, including the size of your home, the climate where you live, and the type of insulation in your home.
When an air conditioner is switched on, it requires a surge in power. The AC will continue to operate at full capacity until they reach the intended room temperature.
In a nutshell, the faster it happens, the more energy the AC will be able to save. Dual inverter air conditioners have a superior cooling ability than other ACs and it reaches the desired room temperature faster thus saving a lot of energy. After reaching the desired temperature, the compressor lowers its speed thus saving even more energy.
But in general, dual inverter ACs tend to be more efficient than traditional models and can save you anywhere from 10% to 30% on your energy bill.
So if you’re looking for a new air conditioner, consider a dual inverter model. They are more efficient and use less electricity than other types of air conditioners, saving you money in the long run!
How Much Electricity Does a Dual Inverter AC Consume?
The power consumption of an air conditioner is determined by its star rating, its tonnage, and the size of the room it is being used in.
Typically a 1.5 Ton 5-star Dual Inverter Split AC will consume around 835.5 watts per hour.
I personally advise you to buy an AC that is the right size for your room, rather than going for a cheaper option. You can take the help of our AC Tonnage Calculator to determine the exact tonnage required for your room.
Do We Need a Voltage Stabilizer For our Dual Inverter AC?
There’s a lot of debate about whether or not voltage stabilizers are necessary for dual inverter ACs. Some people say that they are, while others claim that they’re not actually necessary. The truth is that there isn’t a definitive answer – it depends on your specific situation and the type of dual inverter AC you have.
Although dual inverter air conditioners are more reliable and efficient than traditional ACs, they can still be affected by voltage fluctuations. This is why it’s a good idea to use a voltage stabilizer with your dual inverter AC, especially if you live in an area with frequent power outages or voltage fluctuations beyond the range of 145-290V.
A voltage stabilizer will help ensure that your AC runs smoothly and efficiently, even during times of instability in the electrical grid.
However, most dual inverter AC has a built-in stabilizer and might not require a stand-alone stabilizer. It is needed only if the voltage at your house fluctuates beyond the mentioned range in the manual that comes together with the dual inverter AC.
That being said, in most cases, a voltage stabilizer won’t do any harm and may offer some peace of mind, so it’s generally a good idea to have one just in case.
