Most compact and light weight among compact-sized VRF solutions with R32 refrigerant, while delivering ultimate efficiency.
LG Electronics (LG) has launched the industry’s first 4, 5 and 6 HP R32 refrigerant-fueled variable refrigerant flow (VRF) solution, Multi V S. From residential buildings and apartment buildings – that include small balconies with limited installation areas – to small and medium-sized stores and offices, Multi V S is the smallest and lightest amongst all R32 refrigerant-fueled compact VRF solutions with enhanced efficiency.
As the first single-fan R32-fueled VRF solution to enter the market, the volume of LG’s Multi V S has been reduced by approximately 40% and the weight by approximately 23%. With these upgrades, installations in smaller spaces are possible, allowing more flexibility in the building design and installation stages, saving time and cost. Another benefit is the reduction in refrigerant charge. The Multi V S only requires 4.3kg of R32 compared to the previously required 5.6kg.
Taking into consideration the fact that VRFs are often installed on balconies, the product’s aesthetic has also been enhanced with the new structure. Additionally, the new Multi V S operates at a noise level of approximately 50-52dBs (A), which can be compared to the sound of normal conversation.
The enhanced efficiency of Multi V S has not been affected by its reduction in size. Its high efficiency is due to the inclusion of LG’s R1 compressorTM, which is a hybrid scroll
compressor with a shaft-through bottom compression structure, exhibiting high stability and operating efficiency especially during low-load conditions. The R1 compressorTM allows Multi V S to be more efficient, making it a more eco-conscious cooling solution.
The use of the lower global warming potential (GWP) refrigerant R32 is another key feature of the new Multi V S, with a GWP that’s approximately 68% lower than that of the most widely-used R410A refrigerant, thus meeting the EU’s F-gas regulation requirements. Additionally, R32 is also more cost-efficient, boasting an approximate 69% cost reduction*.
LG’s Multi V S’s internal heat exchanger includes enhanced corrosion resistance with LG’s Black Fin technology, providing stronger protection to air pollution and salt contamination.
LG’s Thain Gummer said: “Multi V S, being the smallest and most light weight of the R32 refrigerant-fueled compact sized VRF, allows high flexibility during installation, but still boasts high efficiency with R32 refrigerant – features that stand out to installers and building consultants when choosing VRF solutions. Starting with the launch of this new product, LG will continue to lead the transformation of the HVAC industry to deliver greener solutions with best-in-class performance through our innovative technologies.”
Outdoor unit sizes vary from 4, 5, 6HP to which up to 13 indoor units can be connected. Multi V S compact is available now.
