An Air Conditioner bearing inverter tag uses a variable-frequency drive to control the speed of the motor and thus the compressor. It consumes at least 30% less (it can go to 50% or more) electricity depending on various factors like the outside temperature ,purpose for which the AC is used, Hence it uses less amount of electricity.
Inverter is a device which supplies variable frequency of power supply on equipments.
Thanks to this function , motor revolution speed can be controlled and it leads to reduce energy consumption.

Non-inverter vs. inverter
Power consumption
Each restart means starting over from scratch, so consumes extra power.Power consumption
The inverter system eliminates waste caused by frequent restarting.
Average power consumption is low.

Outline
To rotate motor, electric current must also run through internal coil.
Large power consumption
Ferrite magnet is placed on surface to rotate motor
No internal coil or electric current, so efficiency is higher than AC. But low rotation force because iron inside is not working.
Neodymium magnet is buried inside, whose magnetism causes internal iron to have rotating force. High rotating force with low power

National Energy SavingNational Energy Savingo The estimated total sales of AC for 2013-2014 is to a tune of 3.5
million.o This figure , according to estimates will rise to 7.4 million by the
year 2018 given the current growth rate.o Presuming, all the ACs are of inverter type only, the total saving of
power would be 74,00,000 X 1516KWH = 11 TWh/Year
o One 500Mw coal fired power plant at 100 PLF produces 4.38TWh/Year ( 500 X1000 X 1000 X 365 X 24)
o In other words the savings of power translates to total production of electricity equivalent to 3 power plants of 500MW each -- that the economy can do away with. Consider the saving of forests, mineral wealth etc.
The enormous potential of energy saving is available as more and more inverter technology is adopted.

R 32 has the benefits of favorable GWP and reduced charge size
Daikin Air conditioning India Pvt Ltd
• R32 is 10% more energy efficient than conventional refrigerant at the same volume.
• Potential of Refrigeration capacity :1.6 times of R410A • Lower pressure loss, when capacity is same, leads to
thinner piping diameter.• GWP of R32 is 675, which is 1/3 of that of conventional
refrigerants such as R410A and R22. Also, it can reduce charge volume by about 30% when optimized. All together it can reduce GWP by 75% in total.

Potential Reductions in CO2 EmissionsPotential Reductions in CO2 EmissionsIt is possible to reduce CO2 emissions significantly, thanks to the high energy efficiency achieved by inverter technology and the energy –efficient R32 refrigerant.
■■Assumption:Assumption:The sales of R32 inverter air conditioners becomes 70% of total sales if R32 inverter equipment increases by 10% every year.
■■Potential CO2 Reduction:Potential CO2 Reduction:Emissions reductions in 2020 could be potentially total around 17 million tCO2.Cumulative reductions between 2014 and 2020 are estimated at 47, million tCO2.
Daikin Air conditioning India Pvt Ltd
Conclusion• The potential of reduction of electricity consumption by
air conditioners is high. Inverter and R32 are the technologies to increase energy efficiency of equipment.
• Inverter technology can increase energy efficiency by 30% compared to non-inverter.
• R32 is 10% more energy efficient than conventional refrigerant at the same volume. GWP of R32 is 675, which is 1/3 of conventional ones.
• When inverter and R32 refrigerant are applied to high-end model, potential increase of energy efficiency will be significant.
