Overview
About Lg’s Multi Inverter Air Conditioning Unit:
The Lg multi split air conditioning inverter heat pump units make it possible to have multiple combinations of different indoor units with different capacities with the advantage of a space saving outdoor condensing unit. The latest Lg Inverter heat pump technology allows greater performance, lower sound levels, lower energy consumption and operates at optimum performance in a rapid and uniform manner until the temperature reaches its optimum set point. The DC Inverter multi split heat pump outdoor units are more efficient than their predecessor and Lg air conditioning’s renowned inverter technology is an innovative, energy-efficient feature that automatically adjusts the unit’s power to maintain room temperature across all the indoor units connected, rather than repeatedly starting and stopping the compressor. The patented Gold Fin™ process on the outdoor condensing unit is standard on the LG multi outdoor units and is an anti-corrosion coating that forms a protective shield against the elements to increase the product lifetime. As there is no need to install a large number of outdoor units, the outside aesthetics of the building are virtually unaffected, furthermore, the outdoor units offer great location flexibility to ease the installation.
Auto Cleaning, Active Energy Control, Wi-Fi ThinQ®
The new slim profile indoor unit has a reduced height of 189mm, allowing installation above door openings and windows. The new multiple stage heat exchanger is folded to form a surround to the upper section of the fan enclosure. This ensures low air velocity, and reduced sound levels, whilst delivering high performance and efficiency. The powerful plasma Ionizer protects you from odors and harmful substances in the air with over 3 million ions to sterilize not only the air passing through the air conditioner, but also surrounding surfaces
The outstanding quality of LG air conditioners is recognised by people all over the world. With sales of 10 million units a year, it has become the top seller of air conditioners in the world. LG Air Conditioning units use R32 refrigerant and unlike ordinary conventional air conditioners, the Lg inverter air conditioners can control the speed of compressors to adjust cooling and heating to keep a linear temperature and outdoor noise levels low. When indoor temperatures reach your desired levels, inverter air conditioners can operate their compressors at low speeds and maintain desired temperatures, thus saving you electricity cost by about 44% compared to conventional units. The NEW Lg air conditioning Deluxe range of Wall Mounted Indoor Units have a new smooth edge design of the fascia, which has a lower profile flatter appearance, and is easy to keep clean. The Deluxe range now includes embedded UVnano™, IonizerPLUS, Wi-Fi ThinQ and it operates at a very low noise rating of 19Db. The main Photocatalytic Washable Deodorizing Filter, provides healthy filtered clean air for the occupants by removing particles as small. Lg air conditioning has used its long standing innovative technology in inverter compressor design, and the ozone friendly R32 refrigerant and combined this with their low noise air movement fan arrangement. The result is a quiet, high performance cooling and heating system, with advanced electronic controls for maximum comfort, controllable and energy efficient. LG’s Energy Display panel monitors the amount of energy levels used. Save on energy consumption while enjoying the cooling by checking your energy level on the air conditioning internal units front panel.
Quiet Operation:
The LG inverter air conditioner uses a DC Inverter compressor due to its optimized refrigeration effect, low noise and high efficiency. DC compressor are much more efficient especially at low loads compared with conventional constant speed AC comps.
Easy Quick Clean System:
With 3M micro protection filter the LG Split Systems are designed with simple cleaning in mind. The grille is completely detachable and access is made simple with the upward opening cover panel.
Healthy De humidification:
Dehumidification mode reduces uncomfortable humidity from the room without over cooling.
Jet CoolTM:
The Jet cool function allows quick cooling. In this mode, cool air is blown at high speed for 30 minutes, until the room temperature reaches 18°C.
Optimized Cooling & Heating Air Flow:
The air vanes will be adjusted according to the mode of operation. In heating mode air will be distributed at a lower angle due to hot air rising.
Even & Fast Air flow:
LG Electronics’ air conditioner improves the difference between high and low indoor temperatures. It allows you to reach your desired temperatures even faster
Chaos Swing:
The most comfortable airflow for the human body can be found in nature. After analysis, LG has applied the scientific Chaos theory to its air conditioners to effectively reproduce a natural breeze. The Chaos technology recreates the flow of natural air by controlling the angle speed and movement of the air vane. It also minimizes the temperature difference in the room, creating a more comfortably conditioned environment.
4 Way Auto Swing:
Most LG air conditioners automatically distribute the air 4-ways to eliminate hot and cold patches to keep the room at a more constant temperature.
