Inverter Technology : Basic Inverter Technology : Basic 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 Inverter Power consumption Average power consumption is low. Average power consumption Non-inverter Each restart means starting over from scratch, so consumes extra power. Power consumption Average power consumption The inverter system eliminates waste caused by frequent restarting. Daikin Air conditioning India Pvt Ltd

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

National Energy Saving National Energy Saving o 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. Daikin Air conditioning India Pvt Ltd

Energy Efficient Refrigerant Energy Efficient Refrigerant • 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 tota l. Daikin Air conditioning India Pvt Ltd
