Neo Plasma Air Purifying System (applied models only)

LG’s unique NEO Plasma Air Purifying System is equipped with 7 specialized filters in 5 separate stages to enhance its cleaning power. It reduces fine dust and mold, unpleasant odors and cigarette smoke as air passes through each filter.

Polluted Air

1. Pre Filter

The antibacterial pre-filter primarily reduces large dust, mold and quilt dust.

2. Nano Carbon Filter

Nano-size carbon filters removes fine odorous particles from the household air resulting in a more pleasant environment.

What is Nano Carbon Ball?

Microscopic sized (1/1000000000) filter to ensure optimal filtration of odors.

200~500nm

3. Triple Filter

The triple filter consists of three specialized filters to reduce the symptoms associated with various organic compounds including formaldehyde. It also has the ability to reduce unpleasant odors creating a more comfortable environment.

Clean Air

5. Plasma Filter

The PLASMA Air Purifying System developed uniquely by LG not only reduces microscopic contaminants and dust, but also reduces house mites, pollen, and pet fur to reduce allergy and asthma symptoms.

Outdoor unit

What is

is a two pipe heat pump system, which is available from 5Hp (single module) up to 40Hp (combination multiple outdoor units together). Up to 40 indoor units can be connected to one system, reducing installation material cost, and installation time. Combined with the many control options on offer, the system can offer a total building solution.

61799 LG Multi V Catalogue 4/5/07 2:16 pm Page 18

Installation Space

User satisfaction is further increased with , by reducing the installation area through efficient utilisation of space assisted by the design of the outdoor unit.

High efficiency linear control

allows capacity control in the range of 10-130% according to the indoor units load requirement. This is carried out by applying the optimised control algorithm using the inverter and constant speed compressors as the load increases/decreases. Combined with the outdoor unit inverter fan motors, this highly efficient inverter system also offers low noise operation, outstanding load response (quick and comfortable cooling and heating), and excellent energy reduction.

Inverter	Constant speed compressor	Highly efficiency linear control

Outstanding installation space utilisation

The two way air induction (front and rear), and top discharge structure, allows outdoor units to be placed directly next to each other - offering reduced installation space, and reduced system footprint.

Conventional

Top discharge with 3way inlet

Top discharge with 2way inlet

Installation of multiple outdoor units in this way can reduce installation by up to 30% compared to equivalent systems on the market (some of which use the 3 way air induction and top discharge method).

Economy

ensures an economic life due to its high efficiency operation, reduced installation material usage, and therefore reduced installation cost.

Long and reduced field piping for flexible installation

Outdoor unit

gives you the ability to connect multiple outdoor units together to form one system (therefore one set of pipes entering the building). This coupled with the long field piping runs makes the system not only very flexible in the type of buildings where it can be installed, but can reduce installation costs and even reduce installation space (especially within the risers).

Conventional Sets of existing 10HP outdoor units are separately installed.

Efficiency

uses the cutting edge artificial intelligence (known as ‘fuzzy control’) to obtain efficient operation and reduce noise.

Components fully protected from the elements

1.Electrical and mechanical parts are totally sealed in their enclosures.

2.Separated equipment space between compressors/control boxes, and heat exchangers.

3.Because the electrical and mechanical parts are sealed in their own enclosures, this makes them much more resistant to environment factors which can cause corrosion (such as dust and rain) - thus improving the lifetime of the outdoor unit.

Outdoor unit

What is

is a three pipe heat recovery system, which means simultaneous cooling and heating is possible from one system. This is achieved using the three pipes from the outdoor unit in conjunction with heat recovery boxes. The heat recovery boxes (or HR boxes) are installed between the outdoor unit and indoor units, and the refrigerant is distributed to the indoor units in its required state (depending on whether or not cooling or heating is required). Heat that is removed from one room can be used elsewhere within the system where it is required, thus making the even more efficient. The

is available from 8Hp (single module) up to 40Hp (combining multiple outdoor units together). Up to 40 indoor units can be connected to one system, reducing installation material cost, and installation time. Combined with the many control options on offer, the system can offer a total building solution.
