00:00Air conditioner has also become very popular in today's time, just like the fridge.
00:05You are seeing the use of air conditioner almost everywhere.
00:09Air conditioner's job is to keep the environment of a place cool like a fridge.
00:14And with the changing environment, the heat is increasing.
00:18And people are using air conditioners and refrigerators to drink cold water and to keep their homes and offices cool.
00:27Today, due to pollution in big cities, the heat has increased so much that you will find a lot of air conditioners in small and large shops, houses and big buildings.
00:37Air conditioning is a process of removing heat from a limited place.
00:42The use of air conditioner is done to cool electronic devices such as computer servers, power amplifiers, etc.
00:51So let's talk about when and who invented this device that finally relieves people from the cold air.
00:59But before the history of its invention, let's know what is air conditioner, which is called air-conditioned in Hindi.
01:09What is AC?
01:11So let me tell you that air conditioner is an electronic device whose job is to cool the air in the environment.
01:18This system converts the hot air of the room into cold air.
01:21AC also filters the air, which also removes the harmful particles of air.
01:26In a way, AC also purifies the air with cooling.
01:30The capacity of the AC is measured in BTU, i.e. British Thermal Unit.
01:35So let's talk about the story of the invention of this device.
01:39If we talk about the invention of air conditioner first, then the invention of air conditioner was made by Wills Heavyland Carrier in 1902.
01:48Wills Heavyland Carrier Engineering was a postgraduate from Cornell University who invented the first air conditioner temperature and humidity in 1902.
01:58Let me tell you that Carrier Buffalo was a new employee in the Forge Brooklyn Printing Plant.
02:03The change in temperature and humidity in their plant slightly changed the dimensions of the printing paper, which caused problems in printing due to the colorful ink.
02:14It is also believed that Carrier invented the air conditioner to solve this problem.
02:19This new air conditioning machine of Carrier created a stable environment in the plant, which made it easier to print four colors.
02:26After this, in 1906, Wills Heavyland Carrier was awarded Appliance for Treating Air US Patent No. 808897.
02:36Let me tell you that after this, many more people contributed to the invention of air conditioner and were successful, for which they also got a patent.
02:43When Carrier was awarded the Patent of Air Conditioning, it was the first of all patents.
02:49Let me tell you that on 26 November 1876, Wills Carrier took an engineering degree from Cornell University in 1900.
02:58And immediately after the engineer's degree, he started working on air conditioning.
03:03And in 1902, he successfully invented the air conditioner.
03:07And after a few years, in 1915, he opened an air conditioner and heating ventilation company.
03:14But the air conditioner made by Wills Carrier is only used in factories and companies.
03:20Not everyone can install it at home, because this air conditioner was so big that it took up the space of a room.
03:26After this, many more engineers contributed to the invention of air conditioner, due to which the air conditioner kept improving over time.
03:33Then, after a few years, in 1945, a small air conditioner was invented by Robert Sherman.
03:40And the name of that air conditioner was Portable Window Air Conditioner.
03:43This window air conditioner not only cooled the house, but also filtered the heat and air.
03:49The story of the inventor of AC
03:53Whenever AC is mentioned, not only Wills Carrier, but many other names are mentioned.
03:58But Wills Haviland Carrier was the first to invent AC.
04:02For this, he is also called the father of AC.
04:07How does AC work?
04:09There is an air cooling process inside the AC.
04:12Hot air goes inside the AC, which is cooled by the air conditioner and taken out.
04:17This reduces the temperature of the outside environment.
04:20Friends, there are four main parts in the air conditioner that complete the cooling process.
04:26Compressor, which is in the part of the AC outside the room.
04:30This compresses the air.
04:32Evaporator, whose work is to exchange heat.
04:36This is a type of coil that takes hot air inside and leaves cold air in the room.
04:42Expansion valve, which is attached to the evaporator.
04:46Through this, air goes from one coil to another coil.
04:50So friends, that's all for today.
04:52Give permission now.
04:53We will meet again soon with a new video.
