With the rise in temperature and the humidity level in our world, we find the air conditioner industry blooming. The last five years have been one of the warmest years recorded in history. Due to this, the AC industry is not simply blooming, but air conditioners are now considered a utility product instead of a luxury product.
Inverter Technology is one of the most efficient technologies for an AC available in the market today. However, manufacturers started coming up with different types of inverter compressors like dual inverter, 8-pole triple inverter, expandable inverter, etc.
So, before purchasing an AC, the type of inverter is something that you should consider.
If you are stuck on which type of inverter you need to purchase, then you are in the right place. Read through the article to better understand the single inverter and dual inverter AC and their differences.
Before we talk about inverter technology, let us understand what a non-inverter AC is. In a non-inverter AC, the speed of the motor is static, and the only way to control it is by turning it on and off.
Since we turn the appliance on and off abruptly, the energy used to function efficiently is more. This can damage the device as well as increase our electricity bill.
The inverter technology is the latest technological evolution made in the motor of the compressors. Thanks to inverter technology, we can control the motor’s speed without turning it off, indirectly controlling the room temperature.
Since the inverter controls the motor, it can automatically reduce and increase the power supply. So, even if the AC compressor is always on, there is a regulation in power.
This is drawn based on the temperature in the room and the level set in the thermostat. An inverter AC consumes about 20-50% less electricity than the traditional non-inverter AC.
Inverter: How Does It Work?
The inverter unit has a motor and a variable-frequency drive. The motor consists of two types of magnets: a permanent magnet with a natural magnetic force, and the other is an electromagnet that runs on electricity. The electric inverter in the drive controls the electromagnet found in the unit.
Both the permanent magnet and the electromagnet have poles (north and south). When the electric current changes in the electromagnet, the poles also invert. In inverter technology these two magnets, when brought together, result either in an attractive force (when the north pole meets the south pole and vice versa) or a repulsive force (when two similar poles meet). The motor functions and rotates due to this change in force.
In case the whole thing sounded a bit complicated for you, I will put it in simpler terms. The inverter regulates and then switches the direction of the electric current. This change forces the motor to rotate. The rotation speed of a motor changes with a change in the switching rate, i.e., how fast you switch the direction of the electric current.
What Is A Single Inverter Air Conditioner?
A single inverter air conditioner runs on inverter technology and contains a single inverter compressor. These compressors only have one rotor, which can change the speed of the motor according to the load applied.
However, the problem arises when the load is too high. In such cases, the rotor will not be able to function efficiently. This means that it will take a long time for the room to cool. This is the main reason why we invented a dual inverter air conditioner.
What Is A Dual Inverter Air Conditioner?
As the name suggests, a dual inverter air conditioner runs on two rotors. It is also known as the twin rotary compressor and is a more advanced version of the single inverter AC. The rotors, kept in the two compression chambers, are placed at a phase difference of 180-degree C. This inverter AC can vary the speed by 10-20%; it can run on extra low speed and extra high speed.
This ensures that the room is cooled quicker and the energy consumed is less. Dual inverter AC also provides a low rate of vibration, unlike the single inverter AC. Another benefit is that there is a reduction in the noise level and an increase in the efficiency of the appliance.
Inverter vs Dual Inverter AC
Compared to a non-invertor AC, both the single inverter AC and the dual inverter AC are more efficient in many ways. However, even between these two, one seems to take the higher position. Let us look at the differences to understand which one it is.
Standard inverters or single inverter AC are equipped with only a single rotor. A single inverter AC is more efficient than a non-inverter AC, but a dual inverter AC overtakes both of them. This is because a twin inverter AC has dual rotors placed at a phase difference of 180-degree C.
Compared to a regular inverter AC, a dual inverter AC is more energy-efficient due to its twin-rotor, wider operational range, and lower frequency of rotation. A dual inverter AC reduces the electricity consumption up to 70% compared to a non-inverter AC and is much more efficient than a single inverter AC.
Most of the dual inverter air conditioners use BLDC motors which can change the compressor’s speed according to the temperature in the room. The compression process happens more effectively since it has two impellers and rotors. As a result, the temperature in the room is maintained even if the compressor doesn’t run at full speed.
Vibration And Noise Emitted
Since the single inverter AC only has one rotor, the load on the compressor is higher. Due to this, the compressor has to work at high speed, which leads to a lot of vibration and noise. On the other hand, a dual inverter has a more stable operation, which means less vibration and noise.
Since the load on the compressor is less for a dual inverter, the lifespan for it increases. Also, there will be less chance of damage to occur due to the high vibration level.
This would be the only downside to a dual inverter AC. But you can’t exactly consider it a downside because it is more technologically advanced and more efficient.
Benefits Of A Dual Inverter AC Over The Standard Inverter AC
We have listed down a few advantages of a dual inverter AC below that you might want to know:
A dual inverter AC is the most economical and energy-efficient type of AC. The technology enables the twin rotors to operate automatically in a power-saving manner. Since the load on the compressor is less than the standard inverter AC, a lot of energy is not used even when the appliance is on. Apart from less power consumption, it also ensures that there is no voltage fluctuation.
The amount of energy used directly affects the cost of the electricity units. That is the more energy use, the more expensive it gets. But, since the dual inverter AC is more energy-efficient, you will not have to worry about your electricity bill again.
Higher Cooling Rate
A non-inverter AC can only change the level of cooling by turning it on and off. However, an inverted AC can automatically adjust the cooling level with the help of its inbuilt motor. A dual inverter AC has a wider operational range which helps to increase the rate of cooling.

We have discussed single inverter air conditioners as well as twin/ dual invert air conditioners, and we concluded that at present, air conditioners that run on dual inverters are the latest and the most efficient ones in the market.
Its twin-rotor, wider operational range, and lower frequency of rotation make it energy-efficient while giving a higher cooling performance. It is also less noisy and more stable with a more increased lifespan than the other ACs.
However, it was a bit expensive. So, if you don’t mind spending a little extra on your AC so that you don’t have to compromise the quality, then go for a dual inverter air conditioner.
