LG’s New Strategic Model Features Cutting Edge Technologies that Combine to Deliver Superior Performance and Top-class Energy Efficiency

LG Electronics (LG) today announced the release of its new Variable Refrigerant Flow (VRF) solution, the Multi V IV. The latest in the compa-ny’s successful line of Multi V products, this model delivers industry leading energy ef-ficiency; cutting running costs and lessening the strain on energy resources. The Multi V IV is equipped with four of LG’s proprietary technologies, and a convenient new fea-ture called smart control, which allows the user to monitor and adjust settings remote-ly.

In particular, the four proprietary technologies of the VRF system consist of the com-pressor, the heat exchanger, the oil and the refrigerant, and the Multi V IV employs cutting-edge technologies in all of these areas, enabling it to go beyond the standard and claim its rightful title as the true, fourth generation VRF solution.

“We are extremely proud of our new flagship system air conditioning solution, the Multi V IV,” said Mr IL Hwan Lee, CEO of LG Electronics South Africa. “The true fourth generation VRF system, it offers the customer unparalleled energy efficiency via four of our own innovative technologies. The Multi V IV is able to boast an impressive ener-gy efficiency ratio (EER) of 4.85. Meanwhile, our High Pressure Oil Return (HiPOR) sys-tem effectively resolves the issue of compressor energy wastage. This industry leading product provides excellent operational savings and greater convenience to our valued, global LG HVAC customers.”

The Multi V IV’s 4.85 EER is one of the highest in the world for a VRF system and has been made possible by LG’s dedication to developing and implementing four industry leading air conditioning technologies. As it effectively minimizes energy loss under partial load conditions, the Multi V IV is able to offer a 30 percent improvement over its predecessor in integrated energy efficiency.

Thanks largely to the implementation of HiPOR, the Multi V IV’s coefficient of perfor-mance (COP) in heating operation has been boosted by 6.7 percent, and in cooling op-eration by 5.4 percent. The new Variable Heat Exchanger Circuit intelligently selects the optimal paths for heating and cooling, contributing a 15 percent improvement to integrated energy efficiency. Meanwhile, LG’s Active Refrigerant Control automatically regulates the amount of circulating refrigerant (per cycle) in five-step increments, leading to a further three percent gain in efficiency.

Finally, Smart Oil Return monitors oil volume in real time, adjusting levels only when needed, thereby eliminating a major cause of energy wastage.

In addition to impressive energy efficiency, the Multi V IV also boasts outstanding per-formance capabilities. Firstly, the unit’s cooling operational range has been expanded from -5 to -10 degrees Celsius, providing an ideal solution for spaces that require chilly conditions year-around, like computer server rooms. Furthermore, the Continuous Heating Operation in Defrost function reduces defrosting times, improving heating ca-pacity by as much as 27 percent in the cold winter months. Another intelligent energy-saving technology, LG’s advanced Snowdrift Detection system turns on the outdoor unit’s fan to remove snow build-up only when necessary.

The Multi V IV also provides enhanced functions and features for greater convenience. For example, the smart control system allows users to remotely monitor and adjust settings via an easily installed smartphone application. The system also supports piping up to an industry leading 1,000m in length, while a lighter outdoor unit makes installa-tion easier and more cost effective.
