MULTI V III: LG’S LATEST VRF SYSTEM WITH SUPREME ENERGY EFFICIENCY
LG’s latest commercial air conditioning system, the Multi V III, has addressed the technical challenges set forth by industry demands: easy installation, cost efficiency, eco-friendliness and, above all, greater energy efficiency. The Multi V III achieves outstanding energy efficiency that outshines its rivals. Measured using a rating system known as the Integrated Energy Efficiency Ratio (IEER), the Multi V III’s IEER comes in at a sharp 21.8, which translates into an additional 14 percent reduction in energy consumption. LG was able to achieve greater energy efficiency in the VRF system by incorporating a new technology called the V-Scroll. The V-Scroll inverter compressor is 11 percent more efficient than a conventional air conditioner’s inverter compressor. It also improves energy efficiency by reducing energy loss from a phenomenon that engineers refer to as slip loss, which is considered normal for most induction motors. The Multi V III has also received the CarbonFree® certification (ARUN072DT3) from Carbonfund.org for the first time in the HVAC industry, further reflecting LG’s devout commitment to the environment. Meanwhile, the Multi V III can use longer piping lengths of up to 3,280 ft that can be installed horizontally and vertically over long distances without elevation factoring as a significant hurdle.
