Vitalizing every environment is the ultimate goal of LG Air

Conditioning and Energy Solution company. It is a vision to

provide great vitality to everyone, everywhere on the globe

from consumers private residences to commercial buildingsand shared communal spaces. Under this unied goal, the

company is committed to providing highly innovative heating,

ventilation and air conditioning (HVAC) solutions, offering

building users completely pleasant environments while using

less energy.

In the last few years, LG has focused on the development

of variable refrigerant ow (VRF) technologies, the latest

series of advanced air conditioning solutions. Standing at

the forefront of realizing LGs aspirational philosophy is the

development of the MULTI V IV: A product which extends

the VRF model, ensuring startling operational efciency

in cooling as well as heating for high-rise buildings, while

defying comparison to any conventional HVACs.

As many manufacturers have now incorporated VRF

technologies into their products, the likelihood of further

innovating on this platform has been perceived as being

fairly low. However, thanks to LGs high level of expertise

and dedication, the company has been able to achieve atechnological breakthrough on its latest VRF system the

MULTI V IV, namely the drastic reduction in the cause of

hidden energy loss, which is a big factor in the ineffective

performance of HVAC.

In the development process of the MULTI V IV, LG has

undertaken close observation, testing, analysis and extensive

R&D, in order to create an industry-rst technology aimed at

improving operational efciency. It is the latest innovation in

LGs long experience in air conditioning which dates back to

1968 and another success for the companys dedicated R&D

capacity. With HVAC innovation at the core of the product,

the MULTI V IV represents a symbol of LGs unprecedented

achievement, driven by the Vitalizing every environment

development philosophy.

MULTI V IV Development Philosophy

The True Leader of 4, MULTI V IV

In order for the MULTI V IV to achieve unbeatable

seasonal efciency, LG has made ceaseless efforts, driving

breakthrough VRF technological advancements that make

the MULTI V IV differentiated from its predecessor, the

MULTI V III. Finally, LG has helped to raise the standard of

VRF technologies by developing the true fourth generation

VRF system, rather than merely upgrading several numerical

indicators or offering generic functions.

Thus, LG is dedicated to the four key elements that

determine operational efciency, which includes compressor,heat exchanger, oil and refrigerant technology. These four

elements play key roles to maximize the energy efciency

of its VRF solutions. However, they also generated some of

hidden loss in conventional models.

As the result of heavy investment and extensive R&D to

remove all forms of hidden loss, companys own technologies,

including High Pressure Oil Return (HiPORTM), Active

Refrigerant Control, Smart Oil Return and the Variable Heat

Exchanger Circuit have been developed for the MULTI V IV,

contributing to raise seasonal efciency.

LG is proud to introduce customers worldwide to its latest air

conditioning solution, MULTI V IV. This groundbreaking productrepresents the embodiment of the companys consistent

commitment to excellence and technological innovation.

SUPERIOR EFFICIENCY VIA

THE INTEGRATION OF SMART

TECHNOLOGIESTodays businesses demand highly efcient temperature

control solutions, capable of providing optimal energy savings

without sacricing performance. When it comes to cooling

and heating a multi-storey or high-rise building, water cooled

HVAC systems have become the solution of choice.

Offering several performance enhancements and greater

installation versatility, LGs MULTI V WATER IV combines

intelligent functions with advanced inverter technology;

boosting both energy efciency and operational range.

This superior water cooled system signicantly improves

return on investment (ROI) with a stellar 5.9 coefcient of

performance (COP) and an equally impressive independent

part load value (IPLV) of 6.73.

Along with outstanding energy efciency, the new solution

comes with a range of truly smart features, including

optimized cycle composition and smart control. For ease of

installation and better economy of space, MULTI V WATER IV

is both lighter in weight and smaller in overall size.

LG, a leading innovator in HVAC technologies, will continue to

develop and manufacture high performance, energy efcient

solutions for the benet of its growing global customer-base.

Adopting a water-based cooling method, this unit optimizes

performance in comparison to compressor capacity. It also

ensures heat exchange performance for high-rise buildings,

thus allowing electrical-savings.

Regardless of outdoor temperature and other environmental

conditions, MULTI V WATER IV is the optimal solution for

high-rise buildings.

New Water-Cooled VRF System

Combines Two Great HVAC Systems

This innovative variable water ow technology looks great in

the lab, but how does it work in actual practice? As a matter

of fact, it turns out working extremely well. LGs water-cooled

VRF system, MULTI V WATER II, was used in the remodeling of

Bouygues Construction Ofce in Paris. The French industrial

group. The ambitious remodeling project became the worlds

rst site using LGs water-cooled VRF. It utilized 162 outdoor

units which is 2,000 horsepower.

Keeping Bouygues

Construction Cool

From the start, the Bouygues Construction ofce was designed

environment-friendly.

It has a glass atrium in the center with a green roof and solar

blinds. The building acquired the NF Btiments tertiares

Demarch HQE label, which certies high performance level in

three different environmental areas at least.

The water-cooled VRF system was the best option for who

wants high energy saving ofce building.

Bouygues Construction (France) is a global player of building, civil works, energy and

services markets and operate its business in more than 80 countries.
