An air conditioner, or more properly, an air conditioner unit is a mechanical-electrical system that treats air in an enclosed area through a refrigeration cycle in which warm air is removed and replaced with cooler air.
The most important process in the operation of air conditioners is the 'refrigeration cycle'. In the refrigeration cycle, which is similar to what happens in a refrigerator, a pump transfers heat from a lower temperature source into a higher temperature heat sink. In other words, warm air is 'refrigerated' and then with the help of fans, pumped out and circulated in a closed space. This is the most common type of air conditioning.
Inverter air conditioners are technologically more advanced than conventional air conditioners. They offer a lot more than conventional ACs. They have faster start-up time than conventional air conditioner units. They are much quieter overall, plus there are no noisy starts and clunky stops as the air conditioner is powered either on or off. Similarly, there are no current peaks as with a standard compressor. There are no temperature fluctuations. There is also less wear and tear, and they last longer than conventional air conditioners.
The most important advantage of inverter air conditioners is it is between 30% and 50% cheaper to run than conventional air conditioners because it uses far less power.
Household brands including Samsung, Mitsubishi, LG, HiSense all have a range of inverter air conditioners. LG makes a range of 'Dual Inverter Air Conditioners'.
