| HISTORY OF AIR CONDITIONER HVAC SYSTEM |
In this 21st-century air conditioner plays a vital role to enhance the growth and develop of the nation. An air conditioner has a major role in a variety of sectors, this invention was enrolled in the name of preservation of the food for a longer time.
Hence the food preservation breaks down towards the growth of the air conditioner, with the help of various principles put forward by scientist and a great thinker. The history of air conditioner HVAC system started in the early days with the need to preserve foods. Foods that are kept at room temperature spoil easily due to the growth of bacteria. At temperature below 4°C (40°F), the growth of bacteria is reduced rapidly.
The air conditioner HVAC system is one of the most important inventions which has a remarkable resemblance in world history.
From cooling and preservation of food, the invention too inclined towards comfort conditioning for humans.
cooling homes, business sectors, and industrial sectors are one of the most important aspects of growth and development.
Well, human comfort is directly proportional to the quality of work, sleep and life which stands one of the most appreciated proposals by everyone.
Well, today we are getting the comfortable temperature in on trigger or by pressing or click on the buttons, but .....
Do you know how this comfort making History of air conditioner HVAC system came into the picture 😕?
What was the history of the air-conditioning😕?
Who invented History of air conditioner HVAC system😕?
So let's begin with this how it come into evidence to the human.
Well in prehistoric times there was no sort of cooling pleasure available to humans either for human comfort or for food preservation.
Since prehistoric times, snow and ice were used for cooling hence it was harvested in winter and stored for summer became popular in late 17 the century.
Well, there the people from the different region used their tricks to cool the surrounding by natural process.
The basic concept of AC was applied by Egyptian, who used to hung the grass in windows and were sprinkled with water, hence the evaporation of water cooled the air blowing through the window and Persian used cooling towers to cool the buildings.
DING HUAN
Well in 2nd-century Chinese mechanical engineer, inventor and craftsman DING HUAN contributed an evaporation cooling methods which sparked up the cycle for innovation in the world history of air conditioner HVAC system cooling.
He invented and crafted a rotary fan of the 3-meter diameter which was operated manually by using jet streams of water for cooling effect.
Which played a vital role in cooling various places and was subjected to the cooling environment.
CORNELIS DREBBEL
In the 17th century, the Dutch inventor Cornelis Drebbel demonstrated Turning Summer into Winter as an early form of modern air conditioning HVAC system for James I of England by adding salt to the water.
Involvement of chemistry
IN 1758, BENJAMIN FRANKLIN AND JOHN HADLEY CHEMISTRY PROFESSOR AT CAMBRIDGE UNIVERSITY
CONDUCTED EXPERIMENT OF EVAPORATION OF HIGHLY VOLATILE LIQUID (ALCOHOL AND ETHER) FOUND EVAPORATES FASTER THAN WATER AND COOLS THE OBJECT UP-TO FREEZING POINT.
CONDUCTED ON MERCURY BULB THERMOMETER AS A OBJECT AND CONTINUE TILL -14 DEGREE.
This chemistry technique of fast evaporation paved the way of inorganic cooling over the organic cooling.
Discovery of chemical which has a faster evaporation rate opens the doors for cooling at faster rates.
This experiment proved that the cooling can be achieved until the formation of ice irrespective of the organic process of cooling.
Franklin concluded: "From this experiment one may see the possibility of freezing a man to death on a warm summer's day."
In 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia, which could chill air, when the liquefied ammonia was allowed to evaporate.
The discovery of the principles of the absorption type of refrigeration in 1824 showed that liquefied ammonia could chill air when it is allowed to evaporate. Ice was created using compressor technology
This principle is also applied in today's air conditioning HVAC system which has a foundation of vapour compression refrigeration cycle.
He contributed towards the foundation of the vapour compression cycle.
In the 1840s, physician and inventor Dr John Gorrie of Florida proposed the idea of cooling cities to provide comfort condition by overcoming the high temperature.
Gorrie believed that cooling will avoid diseases like malaria and making patients more comfortable, but for cooling his hospital rooms, required ice which has to be shipped to Florida from frozen lakes and streams in the northern United States.
To get rid of an expensive logistical issue, Gorrie began to work with the concept of artificial cooling. He designed a machine that created ice using a compressor powered by a horse, water, wind-driven sails or steam and was granted a patent for it in 1851.
Although Gorrie was unsuccessful at bringing his patented technology to the marketplace -- primarily due to the death of his chief financial backer -- his invention laid the foundation for History of air conditioner HVAC system and refrigeration.
JAMES HARRISON
James Harrison was a British Australian newspaper printer, journalist, politician, and pioneer in the field of mechanical refrigeration.
His first mechanical ice-making machine began operation in 1851. His first commercial ice-making machine followed in 1853, and his patent for an ether Vapour compression refrigeration system was granted in 1855. This system used a compressor to force the refrigeration gas to pass through a condenser, where it cooled down and liquefied. The liquefied gas then circulated through the refrigeration coils and vaporised again, cooling down the surrounding system. The machine produced 3000 KG of ice per day.
Willis Haviland Carrier
The commercially available air conditioning HVAC system applications started based on the need to cool air for industrial processes than for personal comfort.
The first electrical air conditioning HVAC system was invented by Willis Haviland Carrier in the year 1902. He was also known as the Father of Modern Air Conditioning.
After graduation, he started a job at buffalo forge company to solve the application problem of a publishing company.
Well, he found that due to humidity the printing product was not satisfactory due to unaligned prints and rapture quality which was less pleasing.
He was sitting on the bench at railway station early in the morning full of the foggy environment around him.
The Idea struct to him and he build a device by using his knowledge of the heating of objects with steam and reversed the process.
Instead of sending air through hot coils, he sent it through cold coils (filled with cold water). The air was cooled, and thereby the amount of moisture in the air could be controlled, which in turn made the humidity in the room controllable. The controlled temperature and humidity helped maintain consistent paper dimensions and ink alignment.
Through a series of experiments, Carrier designed a system that controlled humidity using cooling coils and secured a patent.
which could either humidify (by heating water) or dehumidify (by cooling water) air.
As he continued testing and refining his technology, he also devised and patented an automatic control system for regulating the humidity and temperature of the air in textile mills.
His invention was designed to improve the manufacturing process of a printing plant.
By controlling the temperature and humidity of the plant, the processes were made more efficient as the paper size and the ink alignment were consistently maintained.
It wasn't long before Carrier realised that humidity control and air conditioning HVAC system could benefit many other industries, and he eventually broke off from Buffalo Forge, forming Carrier Engineering Corporation with six other engineers.
The Carrier Air Conditioning HVAC System Company of America was established by him to meet the demand for better productivity in the workplace.
Today, Carrier Corporation is the biggest air conditioner HVAC system manufacturer and marketing corporation in the world in central air conditioning HVAC system.
In May 1922 at Rivoli Theatre in New York, Carrier publicly debuted a new type of system that used a centrifugal chiller.
The system increased the reliability and lowered the cost of large-scale air conditioners HVAC system, and expanding their use throughout the country.
With the advancement in air conditioning HVAC system, there was still the lack of compactness and inexpensiveness which was barking out loudly towards its advancement.
In 1929 Frigidaire showcase his new split system or room cooler which address towards compactness but lacks again in costs and weight.
Then General Electric's Frank Faust improved on this design, developing a self-contained room cooler, and General Electric ended up producing 32 similar prototypes from 1930 to 1931.
Around this same time, Thomas Midgley, Albert Henne and Robert McNary of General Motors bring out chlorofluorocarbon (CFC) coolants into the picture, which became the world's first non-flammable refrigerating fluids, substantially improving the safety of air conditioners HVAC system.
However, the chemicals were dangerous towards ozone depletion decades later and were eventually phased out by governments all across the globe after the Montreal Protocol in the 1990s.
Hydrofluorocarbons (HFCs), which don't destroy the ozone, gain popularity but are eventually linked to climate change.
Residential cooling systems got compact after H.H. Schultz and J.Q. Sherman filed a patent for an air conditioning HVAC system unit that could be placed on a window space. The units introduced in the market in 1932 but were not widely purchased due to their high cost.
Engineer Henry Galson went on to develop a more compact, inexpensive version of the window air conditioner HVAC system which let the pleasure to utilize the cooling system.
Well, many of you might have questioned why such a cooling device is named as AIR CONDITIONER HVAC system?
Why is it called an air conditioner HVAC system?
Shortly after Willis Carrier designed his cooling machine, Stuart W. Cramer invented a similar device to add moisture to the stuffy air in his textile plant. Cramer was the first to use the term “air conditioning HVAC system”, inspired by the idea of “water conditioning”, a then-popular textile making process.
But why is it called an air conditioner HVAC system, not an air cooler? The answer is quite evident: even though AC units have always been used predominantly to cool down the air, their dehumidification properties were precisely why Carrier and Cramer set about inventing them.
IT NOT ONLY COOL BUT it CONDITIONS the air by removing excess moisture, making the atmosphere in your home as comfortable as can be. Hence it is called air conditioning HVAC system.
Well, this was the contribution by the legends due to which we are enjoying a very comfortable life. Not only this, but studies have changed the era of both human comfort along with machine cooling and preservation of food.
well, we neglect the air conditioning HVAC system contribution but this field always focus on contribution to society rather than accepting the gratitude.
