LG Air Conditioners are environment-friendly & future-oriented. To reduce freon gas, a prime ozone destroyer, they adopt alternative refrigerant R-410A, and neo

plasma air-purifying system for powerful sterilization for health-conscious customers. Also, ARTCOOL

series with outstanding designs have received International Forum Design Award, Reddot Design Award

and G Mark. They have improved air flow innovatively to realize world’s lowest noise, and provide a

more pleasant and convenient indoor environment.

Environmental concern 2009As the concern for environment increases day by day, EC Directive made it a regulation to put an

indication on all air conditioning products. With the information regarding energy-saving, customers

will easily understand products considering the environment.

Customers will have to purchase the products considering the energy label to meet their needs. Energy

label shows the energy consumption of the unit classified with 7 different colors..

With the advancement of inverter technology comes more silent, economical and powerful airconditioning systems.

Step-up Inverter by the PFC & the Sine Wave Control Technology (PFC : Power Factor Correction)The LG air conditioner is manufactured using the PFC and the sine wave technology. By the PFC contorl,raising the operating voltage from the existing DC 280V to DC 380V can be done. Thereby, it makes theoperation smooth in a high-frequency area. The sine wave control enables soft operation in a low frequencyarea, thereby expanding the product's operating range. This also markedly improves the product's energy efficiency.

Powerful BLDC CompressorThe LG inverter air conditioner comes with a BLDC compressorthat uses a strong neodymium magnet. Its compressor thus hasimproved efficiency compared with AC inverter. Notably,during partial-load operation (30-45 Hz), the efficiency of thecompressor motor of the LG inverter air conditioner increases,as opposed to the existing AC motors, and the subcoolingeffects of the bigger condensor will further increase theproduct's energy consumption efficiency.

BLDC FanBLDC fan motor offers additional energy saving in operatingmode. Compared with AC motors, BLDC fan motor can cutenergy by 35% at full velocity. AC motor is operating at fullvelocity only, but BLDC Motor can change velocity accordingto load. Energy efficiency levels at low velocities in particularhave been improved by 65%.

Top Class COP• DC Inverter Compressor• BLDC Fan Motor

Comfortable with Fast Cooling & Heating PerformanceWhen the air conditioner is initially activated to either heat or cool, the compressor will operate atmaximum 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 constantlyadjust and vary the compressor speed to maintain the desired temperature with minimal fluctuation toensure that your comfort is not compromised.

Wide Operating RangeWhen cooling computer rooms and other rooms in the event of lowoutdoor temperatures, the BLDC inverter compressor and outdoorBLDC fan motor are used to adjust the air flow and volume, with a viewto ensuring efficient operation by allowing the air conditioner to keepoperating at -10°C without turning it off.
