Understanding air conditioner technologies: Inverter, Digital Inverter, Dual Inverter...

When purchasing an air conditioner, it's common to come across acronyms like Inverter , Digital Inverter , or Dual Inverter . These technologies have a direct impact on energy consumption, thermal comfort, and noise levels. This article will help you understand the differences and make an informed choice.

1. What is an inverter air conditioner?

Inverter technology allows the compressor speed to be regulated continuously, unlike conventional air conditioners which operate intermittently (on/off).

• Benefits :
  • Energy savings of up to 30-40%
  • More stable temperature
  • Less noise
  • Extended compressor life

Examples of brands: Hisense Inverter, Beko Inverter, Samsung AR Inverter

2. Digital Inverter (Samsung)

Digital Inverter is a trade name used primarily by Samsung . It is an electronically optimized inverter compressor for greater precision and durability.

• Finer temperature control
• Silent operation
• Long-term reduction of energy consumption

Examples: Samsung AR5000 Digital Inverter, Samsung WindFree Digital Inverter

3. Dual Inverter (LG)

Dual Inverter is a technology developed by LG . It is based on a compressor with a double rotor, offering more stability, less vibration and faster adaptation to temperature variations.

• Very low noise level
• Faster cooling
• Additional energy savings

Examples: LG Dual Inverter ArtCool, LG S12EQ
