What is An Inverter AC? A Complete Guide For Buyers

by posted in All About Shopping

For those looking for an AC this summer, the most efficient technology that is available on the market today is the Inverter AC Technology. Designed to consume 30-50% less electricity, inverter ACs are the most sought-after products in their category. The problem is not many people know what is inverter AC and how it is different from non-inverter air conditioners.

GreatBuyz has put together this detailed guide on what is the difference between inverter and non-inverter AC. We also picked the top 3 inverter air conditioners you can buy online.

What is inverter AC? 

Air conditioners do not work the same as water coolers. An AC works with the internal air of a room. During the cooling process, an AC sucks in the indoor air, cools it down by passing it through an evaporator, and then circles it back into the room. Along with an evaporator, air conditioners also have a compressor that compresses the refrigerant in the AC unit, which is then used to cool down the air.

Now in regular ACs, the compressor is designed to be either on or off. When it is on, it consumes electricity at its full capacity. In such an AC, when you set the temperature, the thermostat turns the compressor off when the desired temperature is reached. Once the room temperature starts to rise, the thermostat senses the change and turns on the compressor.

The distinguished engineering of inverter AC

The inverter technology in an AC works the same as an accelerator in a car. In an inverter AC, the compressor is given more or less power depending on its requirement. In such air conditioners, the compressor is always on and it draws power according to the temperature of the room and the level set in the thermostat.

Now you know what is inverter AC and how it works. The technology was first developed in Japan to reduce the power consumption of air conditioners and refrigerators. Currently, inverter technology is only available in split air conditioners.

Why inverter AC technology is beneficial? 

As a buyer, you must know that air conditioners are designed for a maximum peak load. Simply put, they come with a “ton” size rating which is an indication of what size room will be ideally cooled by the AC.

Suppose you buy a 1.5 ton regular AC, it will always run at peak load when the compressor is on. In comparison, an inverter AC will run continuously, but it will only draw the needed power that is required to keep the room temperature stable at a set level.

The ability to automatically adjust their capacity gives a huge advantage to inverter ACs. Furthermore, you save a lot on electricity costs. Lower power consumption is beneficial for the environment as well.

Please note: Inverter AC technology is efficient at adjusting the capacity but it is highly based on room requirements. This is why it is mandatory to install the right sized air conditioner in a room.

What is dual inverter AC?

A common problem with single inverter air conditioners is they produce a lot of noise and vibration during operation.

A dual inverter AC uses a dual rotatory system that lowers the rate of vibration and noise, at the same time increasing efficiency. The two rotaries used in a dual inverter AC add a rotational balance as well as compression torque support. Simply put, due to this added support, the compressor rotor can operate between a frequency of 700 RPM to 8000 RPM that directly enables a 1.5-ton dual inverter AC to perform efficiently at the level of 0.3 ton to 1.8 ton!

What is the difference between inverter and non-inverter AC?

Most customers are often seen asking what is the difference between inverter and non-inverter AC. While the differentiation between the two goes beyond just basic engineering, here we present the major differences between an inverter and non-inverter AC, for easy decision making.

An inverter air conditioner features variable speed/ variable tonnage, thus is operationally very different from regular air conditioners that only have a single speed compressor and single tonnage.

Inverter ACs can adjust the compressor speed and capacity depending on the heat load of a room, whereas regular air conditioners cannot self-adjust.

What is the difference between inverter and non-inverter AC can also be understood from how these two control the room heat load. For easy understanding, think of inverter AC as a trouser with elastic and the heat load of a room as the waist size. A room can have variable heat load, metaphorically speaking the waist size keeps increasing and decreasing, but inverter AC acts as elastic that adjusts to the size. Regular Air Conditioners are of fixed size with no scope for adjustment.

Based on BEE power consumption data, an inverter AC with BEE 3 stars rating will be almost 7% more energy-efficient than BEE 3 star rated non-inverter AC.

Here’s a 2018 BEE data of median sample power consumption of Air Conditioners of various tonnage and star ratings:

Now you know everything there is to know including what is inverter AC, its improved dual model, and how inverter AC is different from non-inverter AC. It’s time to go shopping for the best inverter AC for home.
