What is Inverter Air Conditioner?

The inverter technology works like an accelerator in a car. When compressor needs more power, it gives it more power. When it needs less power, it gives less power. With this technology, the compressor is always on, but draws less power or more power depending on the temperature of the incoming air and the level set in the thermostat. The speed and power of the compressor is adjusted appropriately. This technology was developed in Japan and is being used there successfully for air conditioners and refrigerators. This technology is currently available only in split air conditioners.

What is benefit of Inverter Technology?

Every air conditioner is designed for a maximum peak load. So a 1.5ton AC is designed for a certain size of room and 1 ton for a different size. But not all rooms are of same size. A regular air conditioner of 1.5ton capacity will always run at peak power requirement when the compressor is running. An air conditioner with inverter technology will run continuously but will draw only that much power that is required to keep the temperature stable at the level desired. So it kind of automatically adjusts its capacity based on the requirement of the room it is cooling. Thus drawing much less power and consuming lesser units of electricity.

Although air conditioner with Inverter Technology adjusts its capacity based on the room requirement, it is very important to install a right sized air conditioner in a room. Please make sure that you evaluate the room and air conditioner capacity before you make a purchase.

Power Consumption of Inverter and non inverter air conditioners.

Based on data from BEE in 2017, below is the representative (median) sample of power consumption of Air Conditioners of various tonnage and star ratings:

0.75 ton 1 ton 1.5 ton 2 ton
3 Star Non Inverter 627 828 1235 1548
5 Star Non Inverter 576 760 1130 1412
3 Star Inverter 550 726 1077 1344
4 Star Inverter 499 658 972 1208
5 Star Inverter 421 557 815 1005
