What is Inverter AC and How it is Different from Non-Inverter AC

Inverter Air Conditioners

One of the innovative technologies in the air conditioning system is the introduction of Inverter Ac. In this invertor technology the job of the compressor makes it stand apart from the other ordinary AC mechanism. That is just like an accelerator function of a car, which speeds up your car when you push or slow down the speed of the car when you don’t push harder, similarly the compressor is always on the ‘on’ state.

The power and speed of the compressor increases or decreases according to the incoming temperature and the level set in the thermostat. If the incoming air to the compressor is hot then the compressor works at high speed and power and returns cold air to circulate inside the room but in the same way if the incoming air is already cold then the compressor draws less power and  operates at low speed as the air is already at the optimal temperature inside the room.

Origin of Invertor ACs

Japan is the pioneer in this technology as they were the first one to develop this Invertor technology in AC. Japan has also successfully implemented this invertor technology not only in air conditioning systems but also in refrigerators. As of 2018, Invertor Ac’s are currently available in spilt air conditioner models.

Advantage of Invertor ACs

Inverter ACs

As we have seen earlier, the compressor is always in active state in this Invertor AC models. This directly impacts the energy consumption, which is known to save almost 30 – 50% of electricity than the regular AC models. The reason is though the compressor is in the ‘On’ state it does not draw more power always, thus resulting in less energy consumption and saves more on energy bills. Once the room temperature attains a stable temperature the compressor will not utilize much power thus utilizes lesser units of electricity. To get the maximum benefits from these Invertor AC’s always purchase one that is a perfect fit to your room. For example, 1.5-ton AC is sufficient for a standard living room and 1-ton AC for a study room is sufficient.

Major Differences Between a Regular Non-Invertor AC and an Inverter AC

  • Unlike the regular air conditioning unit which runs on same speed, the Inverter AC has variable speed settings in which the compressor is adjusted according to the heat load of the room.
  • The regular AC constantly goes ‘on’ and ‘off’ state, but the inverter AC is always in the ‘On’ state.
  • The non-Inverter ACs are set for handling peak summer time loads which leads them to be over cooled sometimes which is a drawback. Thus, the non-Invertor AC sometimes over cool whereas the Inverter ACs always maintain a stable optimal temperature.
  • In any AC technology, the refrigerant plays a key role which takes the heat from the room that is from the liquid to gas and process it and the compressor compresses it and then gives back from gas to liquid. Thus in a non-invertor AC if the refrigerant is more and the heat inside the room is less, the refrigerant moves in the liquid state and tries to take more heat from the room which results in over cooling the room which is below the set temperature. But in Invertor AC the refrigerant flow rate works according to the heat of the room.
