Inverter vs Non-Inverter AC

Last updated on March 19th, 2021 at 12:39 pm

Compressor is the heart of air conditioners and consumes major power while operation. With aim for reducing power consumption in air conditioners lot of innovation are evolving in compressor technology. Now a day’s AC manufacturer offers inverter AC which are sold as most energy efficient air conditioners, so let us try to understand what is inveter AC and if it can be beneficial for our use and compare Inverter vs Non-Inverter AC.

Inverter Technology:

Inverter is device used in air conditioners to regulate speed of the compressor by varying frequency. In inventor technology compressors are made to run at lower speed during low capacity utilization.

Non inverter compressors are operated at fix speed, hence it is also some time referred as fix speed ACs.

To maintain room temperature non inverter ACs keeps on doing frequent start and stop operation.

Operation methodology for both inverter and non inverter AC is shown below:

As the inverter AC operates at variable speed, the compressor output keep on varying from time to time to maintain desired temperature, hence precise control is available with the inverter technology. Due to consistent variation of load inverter ACs performs well at low load condition.

Air conditioning system are designed to operate at peak load but as the temperature of ambient temperature keeps on varying and it is not possible to keep withdrawing consistent load from air conditioning system. To achieve consistent room temperature air conditioning system must be adjusted and this adjustment brings opportunity for saving power with the change in operation philosophy.

Energy Efficiency Ration (EER) of fix speed AC are good but inverter ACs are winner at SEER or ISEER (Seconal Energy Efficiency Ratio)

With the shift in star rating system of BEE from EER to ISEER, most of the inverter ACs are performing well and ACs with higher ISEER of 5.6 is available in Indian market with inverter technology.

In invertor ACs due to reduced no. of start and stop operation the life of compressor get enhanced and most of manufacturer provides warranty of 10 years on the compressor.

Hence if we compare Inverter vs Non-Inverter AC, inverter AC is must buy option considering consistent temperature, power saving and warranty benefits.
