HUNDRED DISCOVERY: Air conditioning was invented to save the ray in the printer

Let’s take Willis Carrier for the invention of air conditioning. The modern radiator was introduced in 1902, but it had a long series of many new predecessors. The series on the most significant human discoveries was published by Magazn Vkend.

The people thought that they had been in disrepair over the darkness at home. In ancient times, the gods cooled the outer walls of their houses with a water channel (aqueduct). It was not a full inn.

An elegant way was invented by the inhabitants of Persian pilgrimages, where two and five years, thanks to badgrm, completed a technological adaptation to the hot conditions of thousands of years. Badgers are tyrannical or hexagonal chambers, towering and twenty meters above the roofs of houses.

Through the system of gutters, they also capture the smallest corners and lead them down into the house. The air is first cooled above the water tank in the cellar and then distributed to the living rooms. Mrn petlak blows hot air out of the house.

If you step under the airs of a badger, pay homage to your coolant. A perfectly washed system does without electricity. In the cities of another morning, sleep badgers to this day.

But how to cool something deep below the ambient temperature faster? There are several different physical principles for this, with which not only modern air conditioning, but also refrigerators work, he was able to slide and put the radiator in the equipment.

In 1820, the British widow Michael Faraday experimented with ammonia (a spider). He noticed that when this stinking and poisonous gas is compressed into a liquid and then released into the environment, as it expands, the temperature decreases. It is professional for adiabatic expansion and does not necessarily stink of ammonia. It also works with a number of other gases.

At home you can try it with a hair spray, a bomb for a siphon bottle or a card with propane-butane for travel. All these compressed gas containers cool down during intensive use so as not to get your hands on them.

To set a spider or harmful freons in the room would be nonsense, of course. The radiator therefore uses a closed system of propellant electricity, in which the calf is constantly circulating.

In one place, the gas is compressed and liquefied with the help of a compressor, creating heat on the ribbed back of the refrigerator. In another place, the liquid refrigerant is dissolved in the gas with the help of an evaporator, creating frost inside the refrigerator.

And the air conditioning is actually just a refrigerator complete with a fan that cools the air into the room.

Warrior with heat

Another physical principle was used in 1902 by the American engineer Willis Carrier, the inventor of the first truly functional air conditioning. In the New York printer, where he was employed, a beam twisted in the heat of July and the colors dried up due to the high humidity.

Carrier wondered how to solve both problems elegantly and at once. He built a zazen, which drove hot and humid air through a system of pipes with ice water. Water was sprayed on the cold surface of the pipes, which first cooled the air and secondly it removed moisture from it.

Carrierv pbh is a classic example of the American business dream. The company, which he founded on the basis of his case, began to cool the air in cinemas, shops, offices and factory halls. In the 1920s, its customers included the US Congress, the House, and the government and administrative buildings.

After 1950, Carrier’s air conditioning units penetrated households and later automobiles. They began to use in the described physical principle of gas expansion, but this is only quite insignificant technical detail.

Air conditioning shorts either take heat away from the enclosure or cool air. And you know how it works.
