Inverter Technology for Air Conditioner

The idea of having an Inverter Technology in AC originated from Japan and now is used in Air conditioners and refrigerators.

This technology helps to convert the frequency of the current. In common words, Inverter technology is also known as DC Inverter. 

Moreover, an Inverter Air-conditioner auto-adjusts the speed of the compressor so as to control the flow rate of the refrigerant, thus consuming less power.

Now, what if you want to how many tons of AC will fit in your room? Calculate Room Size for AC before purchasing it.

The task doesn’t end here, you have to maintain Air Conditioners by yourself or call the service person for it, as the cool air of Clean AC is unbeatable.

In this blog, you will find almost all the information about Inverter Air Conditioner that you need to know before purchasing an AC.

How Does Inverter Technology work?

The speed of the compressor motor is controlled by inverter and it continuously regulates the temperature. In the case of DC inverters, it has a variable frequency drive that has an adjustable electrical inverter to control the speed of the electromotor. In other words, it controls the compressor and the heating/cooling output.

The incoming AC current comes into DC by the driver and produces the current of desired frequency through a modulation in an electrical inverter. There is a micro-controller which samples each ambient air temperature and accordingly adjusts the speed of the compressor. A microcontroller is enabled to sample each ambient air temperature. Post that it would adjust the speed of the compressor accordingly.

To understand it with an analogy – the inverter works like an accelerator in a car. It uses less and more power as per the need or depending upon the temperature of the incoming air.

How does an inverter Air condition save energy?

The inverter technology saves energy by eliminating the wasted operation in air conditioners by efficiently controlling motor speed. In non-inverter air conditioners, the motor speed remains constant and the temperature is adjusted by turning the motor off and on. This process of switching on and off the motor consumes more energy. In the case of inverter ACs, the temperature is adjusted by changing the motor speed instead of turning the motor on and off.

Understanding the benefits of inverter technology in AC conditioners

An air conditioner comes with a maximum peak load, which is popularly known as AC ton, for example, we say 1.5 ton AC. Different ton specification for AC is for different room size. But not all rooms are of the same size. Taking an example of 1.5-ton air conditioners – The AC will always run at peak power requirement when the compressor is running. The process is a bit different when it comes to AC with inverter technology, it will run continuously but will draw only that much power that is required to keep the temperature stable at the desired level. The capacity is automatically adjusted based on the requirement of the room it is cooling which makes sure AC is drawing much less power and hence consuming lesser units of electricity.

Advantages of Inverter AC

  • The inverter technology consumes less energy and hence it saves about 30 percent to 50 percent of electricity. It is considered the best solution so as to save energy and be economic.

  • There is no voltage fluctuation caused by a compressor.

  • Inverter AC maintains efficient heating and cooling.

  • If you are planning to use Solar PV for air conditioner, then inverter technology is better than non-inverter ACs. There is a double benefit – first, it reduces the size of PV panels because it consumes lesser electricity and secondly it reduces the size of an inverter to be put along with the PV panel.

  • Inverter AC is environment friendly since it uses better refrigerants.

  • The non-inverter ACs are much quieter due to the non-stop running of the compressor.

  • It is suitable for both small and large rooms. Also, it enables you to have a good sound sleep since it would maintain a constant room temperature.

Disadvantages of Inverter AC

  • It is very important to have an insulated room. If the room is not insulated, power consumption increases and so does the electricity bill.

  • It has relatively expensive repair and maintenance due to the expensive service support and the components used.

Star Ratings for Inverter ACs

Are there Star Ratings for Inverter ACs?

In 2016, the Bureau of Energy Efficiency (BEE) introduced a new star rating standard for Inverter Technology ACs as well. All inverter AC models are put in different categories like BEE 3, 4, and 5 Star rating ranges on BEE. As per the study, the BEE 5-star rated ACs are considered the most energy-efficient systems. But it is seen that according to the BEE, a BEE 3 star rated inverter AC is more energy-efficient than a BEE 5 star rated normal split AC.
