18 4. Features and Benefits 4.1 Energy Saving 4.2 More Powerful
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. 4.2 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. 8/36

19 (*PFC :Power Factor Correction)
4. Features and Benefits 4.3 Powerful BLDC Compressor The LG inverter air conditioner comes with a BLDC compressor that uses a strong neodymium magnet. Its compressor thus has improved efficiency compared with AC inverter. 4.4 Step-up Inverter by the PFC & the Sine Wave Control Technology The LG air conditioner is manufactured using the PFC and the sine wave technology. By the PFC control, raising the operating voltage from the existing DC 280V to DC 380V can be done. The sine wave control enables soft operation in a low frequency area, thereby expanding the product's operating range. This also markedly improves the product's energy efficiency. (*PFC :Power Factor Correction) 9/36

20 4. Features and Benefits 4.5 Comfortable 4.7 BLDC Fan
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 4.7 BLDC Fan BLDC fan motor offers additional energy saving in operating mode. Compared with AC motors, BLDC fan motor can cut energy by 34%at full velocity. AC motor is operating at full velocity only but BLDC Motor can change velocity according to load. Energy efficiency levels at low velocities in particular have been improved by 54%. 10/36
