Samsung Triple Inverter vs LG Dual Inverter AC – What’s the Difference?

The use of inverter technology in air conditioner compressors is not something new. It has been in use for many years to improve the conventional compressor because it saves power while making less noise.

Today, almost all the split ACs available on the market work on inverter compressors. Technology is improving, whereby we have a dual inverter and triple inverter ACs available. This article discusses dual inverter AC versus triple inverter AC technology.

By now, everyone knows how an inverter compressor works in an AC. Hence, we move straight to the functioning of the dual inverter compressor.

Dual Inverter Compressor AC

The conventional inverter compressor AC saves power but makes noise because of the vibration caused by the rotation of the shaft when the compressor works at top speed.

A dual inverter compressor system takes care of the vibrations and noise while delivering a higher degree of efficiency. The dual inverter compressor features an advanced BLDC motor capable of working at a more comprehensive frequency range than the conventional compressor.

This technology uses two rotaries at a phase difference of 180 degrees with respect to their compression timings. As this alignment supports the compression torque, it stabilizes the appliance while improving the rotational balance.

Hence, the rotor varies at frequencies ranging between 700rpm and 8000rpm. This variance in the frequency enables the AC to work at different capacities. Thus, a 1.5-ton AC can perform at the level of 0.3-ton to 1.8-ton appliance.

Brands like LG, Toshiba, O’General, and Blue Star offer dual inverter compressor technology in their latest models. LG refers to it as a dual inverter, whereas Toshiba, Panasonic and O’General name it a twin inverter. Blue Star uses the name dual inverter rotary compressor.

Triple Inverter Compressor AC

Samsung introduced the Triple Inverter Compressor AC somewhere in 2019. The dual inverter compressor system got its name from the use of twin rotary functionality. However, the triple inverter system does not have three rotors but uses the 8-pole triple inverter technology.

Just as an additional rotor in the dual inverter system reduces vibrations and noise levels compared to the conventional inverter compressor, the introduction of four additional poles reduces the vibrations. It does not produce many torque fluctuations and enhances the system’s overall efficiency.

Thus, a triple inverter compressor AC can cool up to 67% quicker than the average air conditioner. Studies show that these triple inverter compressor ACs can cool the rooms comfortably even if the external temperatures touch 54 degrees Celsius. These air conditioners can save up to 69% more energy in comparison to regular ACs.

Samsung offers 8-pole triple inverter technology in its 1.5-ton AC model, AR18RV3HETU, AR18RV3JFMC, and others.

Advantages of the Triple Inverter ACs

  • The 8-pole digital inverter maintains the desired temperature without turning on/off. Hence, it consumes less energy.
  • This AC comes with a Fast Cooling Mode that cools the room faster by running the compressor at the maximum and fastest fan speeds for 30 minutes. The 8-pole inverter technology helps reach the maximum frequency quickly.
  • The Samsung model comes with anti-corrosion Durafin technology to reduce condenser leakage and cool the rooms effectively even during the hottest summer months.
  • The Power Boost technology produces fewer torque vibrations to reduce noise levels, enhance efficiency, and consume less power.
  • This technology regulates the temperature according to the number of people present in the room. Thus, a 2-ton AC can work at a 1.5-ton capacity, and the 1.5-ton appliance can function as a 1-ton AC, depending on your requirements.
