When Air conditioner was Invented? – How AC Works 2021

If you have a question in your mind that When Air conditioner was Invented? and Who Invent the first AC? and How an Air conditioner works?

The first modern AC was invented in 1902 by Willis Havilland Carrier, He is a skilled engineer who began experimenting with humidity control rules to solve an application problem at a printing plant in Brooklyn, NY.

Air conditioners, the things we carry on hot summer days, have a long history, dating back to the 1800s. However, it was not until 1902 that the first air-conditioning unit came into the world thanks to a 25-year-old Willis Haviland carrier.

In fact, our life without air conditioners would have been very different, very uncomfortable. But you may ask when and how the ac was invented. Here, we take a look at history.

Unhappy with the concepts of mechanical refrigeration established in earlier years, Carrier’s system sent air through a coil filled with cold water while cooling the air as well as removing moisture to control room humidity.

History Of An Air Conditioner

Here, are we discuss the whole history of an AC that When Air conditioner was Invented and discover and last we discuss How an Air conditioner works?

History Of When Air conditioner was Invented

1820: The same discovery was made by Michael Faraday, an English inventor and, as he liquified and compressed ammonia.

1931: J.Q. Sherman and H.H. Shultes made a separate room air conditioner, which could be placed under the window – It’s called Window Air conditioner. And since then, the design has been ubiquitous for apartment buildings.

In 1933, the US carrier Air Conditioning Company developed an air conditioner using a belt-driven condensing unit and associated blowers, mechanical controls, and evaporator coils, and the device became a model in the growing US market for air-cooling systems.

Carriers incorporate advances in today’s air conditioner vapor compression, diagnosis and control, electronic sensors, materials, and energy efficiency, working on the same basic science as the 1933 system.

The Carrier’s new top-of-the-line central air conditioner, the Infiniti, is very different than the founder’s early model, with upgraded components including a two-stage scroll compressor for quieter, more energy-efficient performance.

1970: Central air conditioner came along and became more popular and famous than window units. A central air conditioning system consisted of a fan, coil, and condenser. and then the ac invented (introduced) in India.

How Air conditioner Works

Air conditioners use refrigeration to cool the refrigerant air, taking advantage of a notable physical rule: when a liquid is converted into a gas (in a process called phase conversion), it absorbs heat.

Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense in a closed system of special phase coils.

The compounds involved contain refrigerants that have properties that enable them to change at relatively low temperatures.

Air conditioners also have fans that transfer hot internal air over these cold, chill-filled coils. In fact, central air conditioners have a complete system of nozzles, designed for air from these serpentine, air-chilling coils, and funnels.

After seeing How AC was Invented and introduce then we talk about how an AC works.

How does an Air conditioner work step by step

Here, I discuss the complete process of an AC and give the answer to How Air conditioner Works? When hot air flows on a cold, low-pressure evaporator coil, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state or form.

To keep cool efficiently, the air conditioner has to convert the (refrigerant) gas back into liquid again.

To do this, a compressor exerts gas under high pressure, a process that produces unwanted heat. All excess heat created by compressing the gas is then pumped out with the help of the second set of condenser coils and a second fan.

As the gas cools, it changes back to liquid, and the process starts again. Think of it as an endless, elegant cycle: liquid refrigerant, a liquid again after the phase conversion of a gas/heat absorption, compression, and phase transition.

This is the working principle of the air conditioner. Here, is the video about How Air conditioners work?

How Air conditioner works

Note: It is easy to see that two different things are going on in an air conditioner. The refrigerant is cooling the indoor air, and as a result, the gas is continuously being compressed and cooled again for conversion back into a liquid.

How Split AC Works

In a split system, the compressor circulates through the condensing and external unit, converting it from gas to liquid state.

The liquid is forced through an indoor evaporator coil or cooling compartment. The fan of the indoor unit circulates the air inside to move through the evaporative wings.

The metal of the evaporator exchanges thermal energy with the air around it. There, the refrigerant changes from liquid to vapor, removing any heat from the surrounding air.

As soon as the heat is removed from the air, the air is cooled and blown back into the house. This is the procedure that describes How split AC works.


Here, we discuss When Air conditioner was Invented and How AC works with the History of an AC. I hope you enjoyed it. So, it’s your turn to share this article more and more.
