Inverter AC vs Dual Inverter AC Differences [2024]

In this article, we have provided the complete and in-depth Inverter AC vs Dual Inverter AC differences so that you can choose one easily. Even though we can survive without an AC in India, especially in the summer, the problem lies with the electricity bill, which is much higher with inverter ACs and dual inverter technology.  In this article, we have compared the features, price, and reliability of inverter vs dual inverter technology.

So. at least start without wasting any time.

Why is Inverter Technology Needed in Air Conditioners?

For the most advanced and efficient electrical appliances, choose those that have an inverter compressor, since inverter technology is designed so that it consumes very little energy. (Almost 20 to 50%) less electricity than traditional air compressors.  As compared to other traditional appliances, inverter technology makes electrical appliances more efficient, consumes less electricity, and produces less noise. With this technology, the motor/compressor can adjust its speed based on the load.

We can easily explain it with this example. 

A vehicle’s engine requires more fuel when we accelerate it to achieve a higher speed, but it needs less fuel when we slow it down. When the AC is turned on, the compressor has to lower the room temperature so it can compress faster, and therefore consumes more power. Inverter technology works in much the same way as an engine. As soon as the room temperature reaches the set temperature, the compressor automatically slows down, reducing the amount of power it consumes.

How is an AC Built with Inverter Technology?

1. Earlier air conditioners used reciprocating compressors, which are quite efficient and provide better cooling, but they consume lots of energy and generate lots of noise and vibration.
2.  We switched to rotary compressors to reduce energy consumption and noise levels. Rotary compressors are quite energy-efficient and produce less noise than AC with reciprocating compressors, but not as efficient over time.
3. Then came the Inverter compressor, which is also a rotary compressor, but its rotor can change speed according to the load, making it more energy-efficient and silent.
4. In today’s world, we have dual inverter compressors, which are even more advanced and efficient than an inverter compressor, because they have two rotors so the load is divided between the two and compressed faster.

Inverter Air Conditioner

 Therefore, if an air conditioner is equipped with an inverter compressor, then it is an inverter air conditioner. Inverter technology is one of the best ways to reduce energy levels and power consumption.  Although Single Inverter compressors are fully compatible with DC and capable of changing speed according to load, they are not as efficient as Dual Inverter compressors. Due to the single rotor, the compression load would be high, affecting cooling efficiency and vibration.

Dual Inverter Air Conditioner

These are also advanced options on the market. Basically, dual inverter compressors, also called twin rotary compressors, have two rotors and are one step ahead of single inverter compressors. A twin-rotor compressor would have a lower compression load than a single inverter compressor, which would increase cooling efficiency and also decrease vibration.  Compared to single inverter ACs, twin rotary compressors consume less electricity.

Comparison Between Inverter AC vs Dual Inverter AC

 Now that we have seen the definitions and principles of dual Inverter AC, let’s differentiate Inverter AC from Dual Inverter AC.

Topic	Inverter  Air Conditioner	Dual Inverter Air Conditioner
Energy Consumption	It consumes more power than Dual Inverter because it has only a rotary system. To produce the same  RPM it requires more energy as compared to Dual Inverter.	Dual inverter ACs consume less energy than normal inverter ACs. A dual inverter compressor has two rotors, so it only requires half the RPM to compress the refrigerant compared to a normal inverter compressor. Two rotors work together at a low RPM, so less power is also required.
Cooling	It is also important to compare the cooling performance of ac units, as we generally want them to maintain room temperature.  Due to the fact that a normal inverter compressor only has a single impeller and rotor, the load for compression is also higher and the output is also lower.	In Dual Inverter there are two rotors and impellers on a dual inverter compressor, so obviously two rotors and impellers are capable of performing the compression process more efficiently.
Compressors	The main difference between dual inverter AC and inverter AC is the compressor. Inverters use a compressor with a single rotor, which is energy-efficient and performs better than a non-inverter compressor.	However, dual inverter compressors are equipped with dual rotors, so the load is divided between both. This provides faster cooling and greater energy efficiency.
Life span	The inverter has only one rotor and due to that, all loads given are a single rotor. Because of that  Inverter has less life span than  Dual Inverter.	Dual Inverter compressors have two rotors and can compress refrigerant with half the RPM of a normal air compressor because they have two rotors. Due to the lower load on the dual inverter compressor, the life expectancy of dual inverter AC is also higher than a normal inverter AC.
Noise and Vibration	The single-rotor compressor produces more noise and vibration because it has to rotate at a much higher RPM to compress the refrigerant.	In contrast, dual inverter compressors are equipped with dual rotors, which can provide good performance even at low RPMs. Therefore, dual inverter air conditioners provide much quieter operation than normal inverter air conditioners.
Price	Inverter ACs, however, are much more affordable than dual inverter ACs.	Dual inverter air conditioners provide much more efficient performance than inverter air conditioners, so they are also very expensive.
