If you are looking to buy an air conditioner in your house, you must be doing some research before zeroing upon which one you should buy.
While doing your research, you must have come across a new term – Inverter AC. So, let's understand what Inverter AC is?
Inverter AC is the latest AC technology in the market. Thanks to the electronic evolution, the AC industry has undergone a tremendous shift.
Inverter ACs are the current trend in the market. Inverter AC is designed, keeping in mind the electricity consumption part. You will be amazed to know that it can save approximately 30-50% of your electricity bill than regular AC.
To know which AC is the best since 2016, BEE has started to give ratings to AC, but earlier, they used to provide a different rating to the inverter and non-inverter AC. But in 2018, this pattern was revised. Now, BEE gives a merged rating to both inverter and non-inverter AC.
How does the Inverter AC work?
Before we understand inverter AC, we must understand what inverter is. An inverter is a device which, in the simplest term, is used to control frequency. An inverter is used in almost every household and it controls the voltage, temperature, and current.
Inverter technology in AC works on the electromotor compressors. The inverter is used to regulate the compressor motor's speed, which in turn controls the temperature. The DC inverter unit consists of a variable frequency drive, which further contains an adjustable electric inverter.
This adjustable electric inverter controls the electrometer's speed, which is the compressor and the heating or cooling device. The drive is responsible for converting the incoming AC into DC and then using a modulation technique, electric inverter produces a current of a desired frequency.
Thus, when you use a non-inverter AC, the temperature keeps on fluctuating whereas it is not the case with inverter AC. In inverter AC, the temperature remains constant, and thus the cooling also remains constant. The microcontroller is responsible for air temperature in both the cases and gets it adjusted according to the compressor's speed.
Inverter air conditioning techniques are highly recommended these days. They are considered to be quite efficient when compared to non-inverter air conditioners. Since the voltage fluctuations are eliminated; thus, spare parts of the air conditioner last quite long, and the shelf life also increases.
Other than that, the customer satisfaction is high because cooling is the same throughout the night. Temperature does not change, and thus the cooling remains constant. As a result, inverter AC is quite silent. They create much less noise when compared to the non-inverter AC.
They also operate on a lower operating cost, and they have a much lesser breakdown than non-inverter AC. But while buying, you might observe that inverter ACs are bit costlier than non-inverter ACs, but with a reduction in the electricity bill, this cost is justified.
Benefits of Inverter Air conditionerff
The inverter air conditioner comes with several benefits and a higher price tag. So, if you want to go ahead with inverter air conditioners then read the following major benefits of the same -
How does an Inverter AC reduces electricity bills?
Since it’s a very important debate when it comes to electricity bills and AC, thus we have decided to dig deeper here. Since, the voltage fluctuations are eliminated in such ACs, thus the cooling requirement is lower and the device also pumps less gas.
As a result, less quantity of heat is then distributed to the condenser. As a result, your condenser is much cooler, and thus there is much less pressure on the condenser. Also, the compressor draws much less current, and thus the compressor is much more efficient.
Some other important observations
Are Inverter ACs slow in operation?
Some people also are of the view that inverter AC cools quite slowly. But this is not true. Let us explain to you how. Non-inverter AC is fixed speed AC, whereas inverter AC has variable speed. Non-inverter AC has a compressor that can be “ON” and “OFF” both whereas inverter AC has their compressor at “ON” mode only.
Non-inverter AC is specifically designed to cool during the peak summer times, and thus they are oversized all the time. The overcooling is the biggest drawback of this AC.
For example, if you have kept your AC temperature at 25, then it will further lower down your room temperature to 22 or 23. But then you may ask what is the use of thermostat then?
Well, the thermostat is known to switch the compressor when the outside temperature has reached 25. But before that, the compressor does the job of converting from liquid to gas and then again from gas to liquid, and then the compressor compresses it.
But in this case, the refrigerant is much more, and the liquid in the room is quite less. Thus, there is not enough heat in the room to convert the liquid into a gas, and it keeps moving as the liquid. Now, the thermostat comes in the picture.
It detects the temperature and switches off the compressor, whereas the refrigerant is still in the liquid state. It absorbs the heat in the room and convert it into gas; bringing the room below the set temperature. Hence, inverter AC cools at an optimum level whereas non-inverter AC cools more than the temperature set.
Let's explore the list and have a look at the features along with the pros and cons of the Top 6 Best Inverter AC in India.
Top 6 Best Inverter AC in India
