Dual Inverter AC vs Inverter AC: Detailed Comparison

The inverter is a device used to curb the voltage and current flow. The inverter generally controls the power supply to the compressor, and built-in inverters are the characteristic feature of AC. We can regulate the gas flow to the Ac by checking the speed of Compression. 

Energy savings are achieved as electricity consumption is very less. Progressive paces in technology paved the way for the rise of dual inverters, three inverters, etc. Dual inverter AC is a commonly used device in recent days.

What Is Inverter AC?

Inverter AC

Inverter AC is recognized to be the greatest incoming air and the level set in the thermostat. If you desire to allow more precise cooling, then the speed and power of the compressor are adjusted according to that. That’s how energy savings are attained.

Intending to modify the design of inverter compressors, a lot of AC brands are producing AC with two rotary compressors rather than one. They are known as dual inverters. The inverter is considered to be an important invention in ACs in recent times. Inverter compressor includes the practice of using special BLDC motors which can alter the speed of the compressor according to the requirement.

In other words, with inverter in place, compressors can run at different speeds according to the cooling requirement and not always with maximum speed. Think of an inverter compressor as a car accelerator. When the compressor needs more power, the inverter gives more power and vice versa. The compressor is always ON with the use of the Inverter Technology but draws more or less power depending on the level set in the thermostat and temperature of the incoming air. The power and speed of the compressor are adjusted appropriately.

This allows in more precise cooling and more importantly, significant energy savings. There are ACs without inverter technology, and they have a reciprocating type compressor. Refrigerant compression used to happen by up and down movement of the piston in such compressors. Their major characteristics are high maintenance costs and low operational speed. But in the case of ACs with inverter technology, they possess rotary compressors instead of reciprocating ones. Inverter Technology can be found in both configurations; Window AC and Split AC.

What is Dual Inverter AC?

Dual Inverter AC

Dual inverter ACs are much nicer than ordinary inverter AC. They normally come with highly developed BLDC motor. The compressor is the main part of the cooling device. The inverter is considered to be the most important invention in recent days. Many AC brands are producing ACs with two rotary compressors rather than one. LG brand calls it as a dual inverter. Dual inverter ACs are much promising than ordinary inverter ACs. In an ordinary inverter ACs, there is the usage of a variable speed single cylinder rotary compressor which operates on a single rotation single compression principle. This type of design generates a lot of vibration and an increase in noise levels.

Two rotary compressors are run with a phase difference of 180° in their mutual compression timing which creates a more stable operation. This enhances the rotational balance and helps in maintaining the compression torque. Now it is easy for the compressor to operate from just 700 RPM to a peak frequency of 8000 RPM. That’s why dual inverter ACs can attain unstable tonnage. Thus a 1.5-ton AC coming with dual inverter technology can vary tonnage from 0.3 ton to 1.8 ton.

Dual inverter compressors utilize a more advanced version of BLDC motors than traditional inverter ACs. There is an immediate cooling at a broader operating frequency or ‘broader tonnage’ due to the dual rotators. Dual inverters deliver better cooling concerning the precision in temperature control. Dual inverters create a greater amount of energy savings than that of a normal inverter ACs.

The twin-rotary compressors in dual inverter ACs bend with a phase difference of 180 degrees, which enables more stability when they are operating at full capacity. More stability demonstrates limited vibrations and less noise. Dual Inverter AC facilitates energy savings of 830 units.

Inverter AC Vs Dual Inverter AC: The Key Differences

We must take an intelligent decision to choose the right type of Inverter AC needed for our day to day life. If it is a normal inverter or dual inverter, we have to check the benefits of both by thorough analysis.

1. Cooling

Fast Cooling AC

An inverter AC’s compressor employs the BLDC motors for its operation. They can alter the compressor’s speed in connection to external demand. When our need changes, the compressor’s speed is adjusted like that.

Compressors provide better temperature control even though they are not running at maximum speed. Dual inverter compressors have a more advanced version of BLDC motors than traditional inverter ACs. This is considered to be the best thing in dual inverter AC. Dual Inverter AC experiences faster cooling at a wider operating frequency.

They are inverters that offer better cooling than the conventional type. Before choosing the type of AC wanted, we must check the constraints and requirements. Essentially, we must go through many options like where we need such an inverter? And what’s the purpose? Then only we could arrive at the best conclusion satisfying these questions.

2. Energy Used

Energy Efficient Dual Inverter AC

Dual Inverters have an extra energy-efficient feature than that of a normal inverter ACs. LG’s dual inverter greatly helps in saving a lot of power as they possess twin compressors. They have a wide operating range and lower frequency of rotation. Thus, dual inverters are advantageous than normal inverter.

3. Noise Emitted

Ordinary AC uses a single cylinder-shaped rotary compressor. The high-speed rotation and vibrational effects are the major consequence of the rotation of this compressor. This leads to a gain in noise levels. If the stability of the system is more, then the vibrations will be less. Therefore, noise is produced in small amounts. Thus, before going to select the inverter, we must think about the noise issues.
