Technology Aspect

Technology is that aspect of ACs, which is getting standardized in the Indian market. The market is full of foreign brands from Japan, United States of America, Korea that are big players in the major part of the world.

All of them are spending a lot on research and development to provide the same functions and features as the other brands are providing so as to compete on an equal platform. LG has been able to differentiate its technology with respect to PLASMA technology in their split ACs that have the most systematic and reliable technology to generate pure and healthy air.

They have been able to carve out a niche for themselves in the room ac market becoming the no1 player in the market thanks to their focused attitude and strategy towards providing health air conditioners.

All other brands have now started offering pure air benefits by incorporating filters etc. as part of their technology.

A) LG Health Air System Window ACs

1) Unique Anti- Bacteria Filter
It removes all dust from the air in the room. It inhibits bacteria proliferation and prevents other disease causing germs from entering the room.

2) Louvre Fins and Grooved copper Tubing
Each louvre fin has small heat radiating pores that boost heat exchange effectiveness and improve cooling efficiency. While the grooved copper tubing ensures maximum exposure of the inner tube surface to the refrigerant, thus enhancing heat transfer.

3) Hydrophilic Coating
Thanks to the hydrophilic coated aluminium fins, the angle of contact between water droplets ( that form due to condensation of atmospheric moisture)and the fin is less than 80 degrees as in the case for uncoated aluminium. This minimises air resistance and ensures optimal cooling performance.

4) 4-Way Air Deflection System and Auto Swing
Adjustable Front louvres help to direct air flow both horizontally and vertically, while the air circulation vents swing constantly from side to side, directing cool air to every corner of the room.

5) Tropical Rotary Compressor
The new Tropical Rotary Compressor not only offers more cooling during the peak of summer, it also resists voltage fluctuation. Thereby considerably reducing power consumption and providing more comfortable surrounding, which leads to higher efficiency and performance.

6) Reversible Open Air Grille & One Touch Air Filter
This arrangement realizes easy ejection of air filter from the unit regardless of installation place.

1) LG Health Air System Split Air conditioners

1) Air Purifying Filter
The filtering sytem utilizes two filters. The Electrostatic Filter removes the finest dust particles and even tobacco,smoke and pollen.The De -odourizing filter removes unpleasant odours, especially those caused by airbone fungi

a) Anti- Fungus Filter
It prevents the breeding of germs such as bacteria and mould which are harmful to the human respiratory tract.


b) Electrostatic and De-odourising Filter
It removes minute dust particles by electric dust collection method and effectivelty eliminates odours by the appliction of a high efficiency De-odourzing Filter.

c) Anti-Bacteria Filter
This function is for quick cooling.In this mode , strong and cool.air is blown at high speeds for 30 minutes until the temperature reaches 18 degrees celsius.

4) Air Flow System
These air conditioners utilize a stremlined air fan and a unique design which create smooth air flow from the air conditonerso that it operates under the lowest noise level.The cross fan , stabilizer and rear guide which cause noise have been redesigned by hydraulic engineering. The number of revolutions have been decreased while incresing the amount of wind. With the best structure gor the air path, the amount of friction has been decreased which has helped to reduce the noise level drastically.

5) Frost -proof Evaporator Pipe
The outdoor fan motor stops when the indoor coil temperature falls below 3 degree celsius and restarts after the coil temperature rises above 6 degree celsius after 90 seconds. It prevents damage to the compressor by ensuring that the refrigerant does not freeze.

6) Auto Operation
It sets the temperature , swithches the fan speed, swings the vertical air direction louvres up and down by a single selecton auto operation mode. All in accordance with fuzzy logic, dependingg on the current temperature.

7) Sleep Mode Auto Control
A touch of the sleep mode button automatically programs the air conditioner to turn off, controls the indoor fan speed and adjusts the setting temperature. Thus it ensures a more comfortable sleep.

8) Auto Restart Function
When the power comes back after a sudden failure , the air conditioner restarts automatically in the same operation condition as before the power cut
.
9) 4 Way Auto Swing
This function blows air simultaneously in four directions, distributing cool air evenly across the room.

10) With the use of a newly designed compressor , humidity is eliminated to create a comfortable atmosphere without over-cooling the room. Thus, avoiding any abrupt, unhealthy drop or increase in body temperature.

11) Efficient Energy Utilization
The advanced grooved copper tubing and Z -louvre fins maximise heat exchange efficiency. Thus helps to reduce power consumption and thus reduces the bills.

12) 2 Way Auto Swing
Hot or cold air gets evenly distributed throughout the room as the auto swing function blows the air in two directions.

13) Child Lock Function
The function prevents children or others from tampering with the control buttons on the unit.The buttons on the indoor display panel can be locked. The unit can then be controlled by the remote.


14) 7 hour On/Off Timer
This function allows a person to set the timer from 1 hour to a maximum of 7 hours. The AC comes with a fully operational remote control..
