Inverter Technology

Inverter technology refers to the compressor within the outdoor unit of the air conditioner. The two most common types of compressors are the fixed speed compressor and the inverter compressor. The fixed speed will run at 100% of its capacity and will stop and start automatically in order to maintain the desired temperature. An inverter compressor will vary its capacity in order to maintain a consistent temperature.

Next Generation LG Multi System
Wide range of Unit combinations
12 different types of indoor unit 15 different capacity of outdoor unit
An inverter's capacity will fluctuate in order to match the air conditioning requirements, so an inverter can be more energy efficient than a constant speed compressor.

Cooing Load Time

More Comfortable
When the air conditioner is initially activated to either heating or cooling, the compressor will operate at maximum speed to reach the desired temperature quickly. Once the desired temperature is achieved, unlike conventional air conditioners that turn the compressor on and off, LG inverter units adjust and constantly vary the compressor speed to maintain the desired temperature with minimal fluctuation to ensure that your comfort is not compromised.

More Powerful

With a wider operation range for heating and cooling, the inverter is able to operate in even the most extreme outdoor temperatures. An inverter compressor can also operate faster than conventional air conditioners thus allowing the air conditioner to reach the set temperature faster and brings you comfort sooner.

NEO-Plasma Air Purifying System
The NEO PLASMA Air Purifying System developed uniquely by LG not only removes microscopic contaminants and dust, but also removes house mites, pollen, and pet fur to help prevent allergic diseases like asthma. And it also eliminates bad odor by catching odor particle. With a filter that can be used over and over again by simply using vacuum cleaner, you can enjoy clean fresh air. Odor Free! Dust Free! Allergy Free!
Optimized two way airflow for cooling and heating (only LIBERO Models)
For cooling, the vane is adjusted upwards to let the cold air travel up and air condition a wider area. As for heating, the vane sends the heated air downwards to heat the space from the floor for a pleasant and balanced room temperature.
