LG ELECTRIONICS LAUNCHES INDUSTRY-FIRST COMPACT R32 VRF SOLUTION, MULTI V S
OOO OOO. OO, 2019 – LG Electronics (LG) has launched industry’s first 4-6 HP R32
refrigerant-applied variable refrigerant flow (VRF) solution, Multi V S. From
residential buildings, condominiums with small balconies that have limited
installation areas, and to small and medium sized stores and offices, Multi V S
is the smallest and lightest among R32 refrigerant-applied compact sized VRF
solution with even enhanced efficiency.
First single-fan R32-applied VRF solution to enter
the market, the volume of LG’s Multi V S has been reduced by around 40% and the weight around
23%. With these upgrades, installations in smaller spaces is possible and the
installation time and cost has been reduced, presenting more flexibility in the
building designing and installation stage. Another benefit is the reduction in
refrigerant charge, only needing 4.3kg compared to the previous 5.6kg.
As VRFs can be located in the balconies as well,
the aesthetic aspect of external installation view has also been enhanced with
the new structure. In terms of the noise level, the new Multi V S is assessed
to be around 50-52 dB(A) on par in comparison to 50dB(A) of talking.
What’s most important is that the efficiency was
not sacrificed during the size reduction. Rather, the seasonal energy
efficiency ratio (SEER) and the seasonal coefficient of performance (SCOP)
meets the top energy labelling standard of the Europe Commission, who sets one
of the strictest standards around the world. Multi V S falls under either the
A++ or A+++ grade in terms of SEER and SCOP, which is mostly higher than other
products in the market.
This incomparable high efficiency was made possible
with LG’s unique original technology, the R1 compressorTM. The
compressor adapted in the Multi V S is an LG-exclusive hybrid scroll compressor
with a shaft-through bottom compression structure. Resolving the endemic
problem of a relatively low efficiency in the widely used rotary compressor and
taking the advantages of scroll type compressors, LG’s new R1 compressor
exhibits high stability and operating efficiency especially during low-load
conditions. The R1 compressor allows Multi V S to post ultimate efficiency while
meeting the needs for a more environment friendly cooling.
Adding to the eco-friendliness, the application
of the lower global warming potential (GWP) refrigerant R32 is another key feature
of the new Multi V S. R32 itself has merits in that it is cost-efficient, with around
69% reduction in cost (based on EUR, size 6HP) but the GWP of R32 refrigerant is also
around 68% lower than that of the most widely used R410A refrigerant and meets
the tightening F-gas regulation of the European Union.
Signature features of LG’s Multi V lineup have also
all been adopted, one of which is the dual sensing technology. The technology
allows more comfort and efficient operation by operating based on two factors
that affect convenience, temperature and humidity. The fans inside have
enhanced corrosion resistance with LG’s “Ocean Black Fin” technology, providing
stronger protection to air pollution, salt contamination, etc. The design of
the fan is biomimetic, which enables higher air volume to blow in a quieter
OOO said, “Multi V S, being the most compact and light
weight of its R32 refrigerant-applied compact sized VRF class, allows high
flexibility during installation but still posts high efficiency with R32
refrigerant, which are significant to installers and building consultants when
choosing VRF solutions,” adding, “Starting with the launch of this new
product, LG will continue to lead the transformation of the HVAC industry to
deliver the best-performance yet a greener solution with our innovative
Sizes vary from 4, 5, 6HP and 8 to 13 indoor units
can be connected with almost all existing R410A indoor units are compatible
with the new product. Multi V S will be available in OOO, OOO, from OOO, OOO.
