You may have heard about inverter AC frequently, but wonder what is it and what makes it different from a Normal AC? Well, in this article I will explain what is an Inverter type air conditioner and how exactly it works. I will not try to go in deep technicality and will try to explain things using some examples so that everyone can understand about an Inverter type AC.

I am pre-assuming that you probably know a little bit about a non-inverter type AC. If not, read this article thoroughly and don’t miss any point.

What is an Inverter AC?

An Inverter AC is a type of AC in which the compressor works continuously at a variable speed. It’s a new type of innovation in the Air conditioner industry. The compressor does not stop automatically like a non-inverter type AC, resulting in 20-30% more energy savings.

How Does an Inverter AC Works

Before I start explaining, you should understand that your room cools down because of the outdoor unit i.e, compressor. The working on an Inverter type air conditioner is very simple. Let’s suppose that the room temperature is 38°C which is very hot. Now when you turn on your AC and set the desired temperature to 21°C the compressor immediately start to work.

Step 1: A variable-frequency drive converts the incoming AC (alternate current) current to DC (direct current). During this time, the compressor motor works at a full pace to reach the desired temperature (21°C) as fast as possible.

Step 2: After a few minutes, when the thermostat detects that the temperature has reached the 21°C mark, the microcontroller’s work starts.

Step 3: The microcontroller controls the speed of the compressor’s motor according to the ambient air temperature. Your room temperature always remains in the optimal cooling range. So basically, your compressor never stops during the operating time period.

Benefits of Inverter Type AC

There are three types of major benefits of an Inverter AC.

Instant Cooling

An inverter AC uses more power at the beginning and due to this, it cools faster than a non-inverter AC. After it reaches the desired temperature, it gradually varies the power according to the requirement.

Saves Energy and Money

The compressor of an Inverter AC works according to a variable-frequency drive. It changes the speed of the compressor motor continuously and does less power consumption. As a result, you get less monthly bills which obviously saves your money up to 30% compared to a non-inverter AC.

Noise Reduction

Now you know that an inverter air conditioner works in low power mode. Due to this fact, it does not create buzz sound from the outdoor unit and remains more quite all the time.

Difference Between Inverter and Non-inverter AC

FactorsInverter ACNon-Inverter AC
Initial CostHighLow
Instant CoolingFasterLower
Power UseEconomyVery High
Compressor TypeReciprocating with variable speedReciprocating with fixed speed

The fact of the day

An inverter type AC has high initial cost than a non-inverter type AC. The initial cost will be recovered in two to three years by saving your monthly bills.
