History of Air Conditioning

Isn’t AC’s doing enough to cool down your summer? Here are few fun facts and history about our beloved air conditioner

Surviving the heat has always been a tough challenge throughout the history, from cavemen to the modern civilization. Unlike cavemen who relied on age-old natural techniques to sustain the heat, we the modern millennials, thanks to the advancement in technology, we make use of many efficient and effective ways of staying cool. Throughout the history men were always in search of a better way to beat the heat, not only their motive for cooling was intended towards comfort and luxury but at a certain point this was inevitable and had become the question of survival. Especially in the countries in the middle east where the average temperature ranges north of 45-degree Celsius.

Thanks to the advancements in the field of heating, ventilation and air conditioning (HVAC), we are today possessing few of the remarkable ways of retaining body temperature and preserve food for the longer durations.

The evolution of cooling systems throughout the ages

The Cavemen

The stones have proven to be natural insulators and hence our cavemen used to rely on finding refuge in old stone caves for shelter and to prevent heat. Also whenever cave wasn’t an option, the dug burrows in the ground. Even today, the stone buildings are more efficient in regulating temperature.

Egyptians

One of the notable civilizations of man king had a unique solution to beat the heat. The started with hanging the wet reeds on their open windows so that the crosswinds blowing into their houses would be cool.

Chinese

Who isn’t familiar with the iconic hand fans from the land of China? The invention of those stylish fans was purely out of necessity and dates back to the second century BC.

Middle East

We all are familiar with the Disney’s game called Aladdin, the standout feature in this game was the famous Aladdin’s castle. Ever wondered the importance of those tall towers? In fact, it is a structural marvel, where the tall towers and the underground channels acted as the temperature regulator, to bring in cool air from beneath and drive off warm air out of the tower.

Greeks

Greeks followed a simple technique which allowed them to continuously flow water through the aqua-ducts. This enabled them to monitor temperature at public baths and maintain heat or cool down the area as per their requirements.

Victorians

They added to the structural aspects of the building like the people from the Middle East. The common architectural design included high ceilings, deep porches and large windows, which provided enough cross ventilation to keep the room cool. These techniques are still in practice even today in many countries.

Modern times

Willis Haviland Carrier is a well-renowned name in the HVAC world and often known as the father of Air Conditioning. In the year 1902, he discovered the relationship between temperature, humidity, pressure and dew point which led him to the invention of “the apparatus for treating air” which he then on patented in the year 1906. These developments inspired him to form his own company, Carrier corporation in 1915. He also made a revolutionary contribution by replacing the bulky rotary compressor with centrifugal compressors.

Through the history- evolution of AC’s

1813: The very first ever steam-powered refrigerator was built by Jacob Perkins

The 1830’s: To cool the patients suffering from yellow fever and Malaria, Dr John Gorrie invents the ice making machine

1899: Concept of comfort cooling gained popularity

1904: St. Louis had a fully air-conditioned Missouri state building was featured in the world fair.

1914: Charles Gates became the owner of the very first domestic AC system installed.

1917: Cinema got its very first AC

1928: The first practical household AC unit was demonstrated by the Carrier Corporation. Also, DuPont introduced its Freon.

1930: The first air-conditioned car was introduced in the rail route of Baltimore and Ohio

1936: The first air-conditioned passenger plane was introduced by United Airlines

1939: First AC car was made by Packard

1953: The sales of AC units crossed the milestone of 1 million, in total sales

1987: Important and much needed Montreal Protocol was signed to regulate the usage of CFC’s in the HVAC systems which was the primary reason for depleting the ozone layer.

1997: Restrictions were imposed on environmentally harmful refrigerants through the Kyoto Protocol

2002: As per estimation the AC production crossed over 6.7 million units

Interesting facts about your Air Conditioner

The most common terminology used to measure the cooling capacity of any Ac is represented by the term “tonnage”. One ton simply means the amount of heat absorbed by melting ice weighing one ton!

The employers were convinced that AC promoted laziness in their employees work environment and hence were against the idea of installation of air conditioning systems in 1940 till late 1950. But soon they showed interest towards an air-conditioned environment upon noting a significant increase in the productivity of their workforce under AC installed environment.

Ever wondered what are these terms like R-22, R-12, R-134, it emphasizes the chemical structure of the molecules in an alkaline refrigerant. Upon adding 90 to this number, using the resulting three-digit number, we can derive the number of carbon, hydrogen and fluorine atoms present in the molecule.

The common misconception among room AC users is that the air is cooled by passing through a system of coils but in fact, the air is never passed through the coils but passes over the coils. The cooling is achieved by refrigerant which draws the heat from the air as it passes over the evaporator coils.
