History of HVAC

HVAC is mainly based regarding inventions and discoveries made by  Nikolay Lvov, Michael Faraday, Willis Carrier, Edwin Ruud, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and many others.

The first comfort air controlling system was made after multiples inventions and after a lot of trial and error. It was first set up by Alfred Wolff in 1902 for the New York Stock Exchange. Whereas another expert Willis Carrier developed the process AC unit for the Sacketts-Wilhems Printing Company. The first school which offered HVAC training for the interested pupils was in Coyne college back in 1889.

The industrial revolution, new methods of modernization, higher efficiency among workers and machines influenced the development of different components of HVAC systems and the production also went hand in hand as all these factors allowed newer companies to develop the system controller and introduce modern forms of HVAC units.

The mechanical aspects of air conditioning development moved at a very fast pace throughout the first stage of the 20th century; the electronic and technological developments allowed mankind to be depended on them and hence electronics could manage to take centre stage since then. COmputers gave manufacturer ideas about how intelligently the whole weather modelling of buildings can be done accurately so that they can determine the heating and cooling loads. The modern electronic equipments have made them smarter, smaller and more efficient. They have reshaped the process of how the systems are installed, maintained and operated.

In terms of HVAC systems the records they are achieving every year are groundbreaking, to say the least, and where they intend to reach in the future best sums up with a single word that is-sustainability. We will definitely see larger improvements in energy efficiency over the next decade than we have ever seen in the history of air conditioning. The future holds a lot of advancements in the system but not only on technological grounds but even in the way the buildings are designed and built for better air conditioning.
