Know the Story Behind the Evolution of Modern Air Conditioners
Using modern air-conditioning systems is very easy as they come with very simple controls. Today, it’s easy for anyone to use an air conditioner, even if he/she hasn’t used an AC before. Moreover, AC repair Delray Beach services are also available for 24×7 so that you don’t need to live in a hot and humid environment for too long. But do you know when was the first air-conditioning system was introduced?
If talking about the modern air-conditioning system, then it was first invented in 1902 by Wills Carrier. But people were using air-conditioning systems even before that and for a very long time. Let’s understand the evolution of air conditioners from the experts of AC Repair Delray Beach.
It is believed that the first air-conditioning system was introduced in the 2nd century by a Chinese mechanical engineer Ding Huan. He invented a rotary fan, having 7 wheels with a diameter of 3 meters. It was basically a manually powered deviceand a certain number of people were needed to make it functional. It was a great availability at that time when the human technology was not that advanced. This technique was in use for a very long period, for almost14 centuries.
A new technique was introduced in the 17th century to get rid of the intolerable summer heat. People used to collect ice in winters and store it for summers, but it wasverydifficult. Only kings and some specific people could afford this service because the task is performed by prisoners or by paid workers.
Then comes Wills Carrier who invented the first electrical air conditioner in 1902. He had a great expertise in heating the objects with steam. Once, he was assigned with the task of removing excessive moisture present in a printing factory. For this, he reversed the process of heating the object by sending the air through cold coils rather than using hot coils. It was a successful experiment, but along with removing humidity from the indoor air, the atmosphere also became cold. This is how the first electrical air conditioner was introduced, and we are still using this principle to control the temperature in our homes.
Initially, ammonia, methyl chloride and propane were used in electric AC, which are toxic and highly flammable gases. Later in 1928, this issue was resolved by Thomas MidgleyJr. who invented Freon, which was a non-flammable and non-toxic chlorofluorocarbon gas. After a few decades, it was discovered that the Freon is damaging the ozone layer of the Earth. This issue was resolved after the introduction of Puron (R410a) as it was a safer replacement for Freon (R-22).
To enhance air-conditioning experience even more, smart thermostats have also been introduced. All these inventions ultimately made the human life much easier and comfier.
