After some six months of market study, personal experiences and in visiting various dealers/ showrooms I reached to the conclusion there are
NO ‘number one ’ or ‘number two ’ between air conditioner manufacturers. Some companies like Hitachi & Daikin are revered in India and sale only self proclaimed 'premium quality ' air conditioners due to their face value where as general consumer appliance manufacturers like LG & Samsung have their range from the very bottom to the top. Hitachi have an unprecedented reputation in India which they built through the last two decades when there was simply no competition at their level on Indian market by providing excellent products at sky high prices. Amazingly even today with their extra-high quoted price people go by hype and buy them blindly cause its a 'Hitachi'.
But for sensible buyers who wants the most out of his rupee find the current landscape to have changed a lot with multiple international air conditioner companies jumping in the lucrative and nascent Indian air conditioner market raising the performance bar even higher with cut throat competition. This is a boon for us buyers. In the Inverter air conditioner market I find Hitachi and Daikin as just two players along with Sharp, Panasonic, LG, Mitsubishi and Carrier.
After personally experiencing the Sharp, LG and Hitachi Inverter air conditioners, I found Sharp and LG's to be much superior than the similar Hitachi/Daikin ones in terms of performance, reliability and product quality. LG uses the most advanced technology of all Inverter air conditioners currently available in India and one will be a lucky to get their 1.5 Ton version at less than INR 54K. Also the product quality of their Inverter air conditioners are in altogether different premium level in comparison to their non-Inverter air conditioners models.
At the end I went for two 1.5 Ton Sharp Eco-Inverter air conditioners having in-built
Plusmacluster air purifier technology. My 1.5 Ton
Sharp AH-XP18MV Inverter air conditioners comes fully imported from Thailand with an MRP of INR 50K. The indoor unit looks gorgeous, have amazing cooling performance capability and just oozes quality. If one can really bargain well he will get them for 43K. And if one can really really bargain like me, he will get them at 41K, below which the dealer will simply refuse to sale since their profit margin falls below 1K. In comparison the best price I got for the Hitachi i-Clean non-Inverter 1.5 Ton, 5 star air conditioner was a sky high 42K where as their i-Tec Inverter 1.5 Ton costs an earth shattering 56K!!!
Sharp 1.5 Ton Inverter air conditioners comes out on top with class leading
cooling performance scientifically measured as
COP of 3.66 (W/W) and
EER of 12.49 (Btu/hW) and at the same time be more environmentally conscious by using less R410A gas. Performance & efficiency speaks. In contrast the Daikin could manage a COP of just 3.23 and EER of 11 max while Hitachi does a little better of COP of 3.51 and EER of 12. Mind you both of them cost a minimum of 15K more than Sharp!!!
COP of some 1.5 Ton Inverter air conditioners available in India:
Sharp (AH-XP18MV): 3.66
Hitachi (RAS018EQE): 3.51
LG (BS-Q186C7M1): 3.34
Carrier (42CVSR018-703): 3.31
Panasonic (CS-S18NKYP): 3.27
Daikin (FTKS50): 3.23
Mitsubishi (MSY-GE18VA): 3.12
Sharp Inverters not only have the best cooling performance in 1.5 Ton category, it has one of the widest cooling capacity range. As Inverter air conditioners are constantly varying its cooling capacity according to the needs, when set temperature is achieved the Hitachi will climb down from its rated cooling capacity 5.33 kW to minimum of 2.37 kW to save power consumption, Daikin will climb even lower from their rated 5 kW to 1.7 kW to save more power, Sharp will climb down from rated 5.27 kW to even lower 1.6 kW and consume even less power under part load.
Comparison of cooling capacity range (Min - Rated - Max):
LG (BS-Q186C7M1): (0.9 - 5.2 - 6) kW.
Range: 6 - 0.9 = 5.10 kW
Sharp (AH-XP18MV): (1.6 - 5.27 - 6) kW.
Range: 6 - 1.6 = 4.40 kW
Daikin (FTKS50): (1.7 - 5 - 6) kW.
Range: 6 - 1.7 = 4.30 kW
Mitsubishi (MSY-GE18VA): (1.4 - 5 - 5.4) kW.
Range: 5.4 - 1.4 = 4 kW
Hitachi (RAS018EQE): (2.37 - 5.33 - 6.04) kW.
Range: 6.04 - 2.37 = 3.67 kW
LG Inverters are simply unbeatable with their widest cooling capacity range of 5.10 kW and under part load conditions can come down from their rated 5.2 kW to an amazing 0.9 kW consuming very very less power. Hats of to LG to perform such a technically daunting task for controlling a 6 kW compressor to run smoothly at just 0.9 kW!!!
I immediately dumped the Hitachi for their un-justified sky high pricing and went for Sharp Inverters, other reasons being their excellent customer support and after sales service provided in Kolkata. If I had the budget of over INR 1 lakh, would have definitely gone for these LGs all the way for my two rooms.
Below are some points in reference to LG 1.5 Ton Inverter air conditioner (BS-Q186C7M1) which I believe makes them the class leader in India:
1) Most powerful airflow of all Inverters out there with a maximum indoor airflow rate of 19.5 cubic meter/min which can extend upto 30 feet. In contrast Daikin can do a max of 14.7, Hitachi a 16.7 and Sharp a 16.8. Personal experiences with Hitachi, LG and Sharp affirm this to be true. LG pumps chilling cool windblasts!!!
2) Indoor Unit is super silent thanks to the use of unique skew fan which minimizes surface pressure of the fan blade when in contact with air thus reducing peak noise and is powered by the most powerful brush-less DC motor using Neodymium magnets ever used in indoor units in India. Use of Neodymium magnets inside the motor greatly enhances efficiency and torque, capable to revolve the fan at much higher revolutions per minute resulting in phenomenal windblasts. Being brush-less they produce very less noise. Personal experiences with Hitachi, LG and Sharp affirm this to be true. LG currently hold the record of India's lowest noise level of 19 dB.
3) As Inverter air conditioners are constantly varying its cooling capacity according to the needs, LG Inverters are simply unbeatable with their widest cooling capacity range of 5.10 kW and under part load conditions can come down from their rated 5.2 kW to an amazing 0.9 kW consuming very very less power.
4) Like Sharp uses of all-aluminium condensers with canalicular tubing on there outdoor units which are the next step towards advanced technology and improved efficiency where the refrigerant enters multiple tubes at the same time, therefore enhancing the air conditioners performance and reduce the power consumption.
5) While LG uses the same type of ionizer air purifier as Sharp Plasmacluster, it adds a air filter to remove harmful substances floating in the air which is an added bonus.
6) Just awesome built quality. Triple thumbs up here. Please do not mix it with other LG non-Inverters here. They do not even come close.
Would have definitely gone for these LGs all the way if I had a budget of over INR 1 lakh for my both rooms.
