History of Air Conditioning and Refrigeration

Willis Carrier: The Father of the Air Conditioner

The main present day air con and cooling system was concocted in 1902 by Willis Haviland Carrier, a gifted specialist who started trying different things with the laws of moistness control to take care of an application issue at a printing plant in Brooklyn, NY. Obtaining from the ideas of mechanical refrigeration built up in before years, Carrier’s framework sent air through loops loaded with icy water, cooling the air while in the meantime evacuating dampness to control room stickiness. In 1933, the Carrier Air Conditioning Company of America built up a ventilation system utilizing a belt-driven consolidating unit and related blower, mechanical controls, and evaporator loop, and this gadget turned into the model in the developing U.S. commercial center for air-cooling frameworks.

Willis Haviland Carrier was an American architect and designer, and is known as the man who invented present day ac and cooling.














The present air conditioning systems, while working on an indistinguishable principal science from Carrier’s 1933 framework, fuse headway’s in vapor pressure, diagnostics and controls, electronic sensors, materials, and vitality effectiveness. Bearer’s new first class focal ventilation system, the Infinity, is far not quite the same as the originator’s initial models, highlighting propelled segments including a two-arrange scroll compressor for calmer, more vitality productive execution.

His development was intended to enhance the assembling procedure of a printing plant. By controlling the temperature and moistness of the plant, the procedures were made more proficient as the paper estimate and the ink arrangement were reliably kept up.

The Carrier Air Conditioning Company of America was built up by him to take care of the demand of better efficiency in the work environment. Today, Carrier Corporation is the greatest ventilation system maker and advertising enterprise on the planet in focal aerating and cooling.

The revelation of Freon in 1928 by Thomas Midgley, Jr., a more secure refrigerant to people contrasted with the poisonous and combustible gasses, for example, alkali, propane and methyl chloride starts the innovation of ventilating frameworks for private, mechanical and business applications.

Lamentably, the utilization of CFC and HCFC refrigerants are causing the exhaustion of ozone layer in our air that is causing destructive beams to infiltrate our earth. More current ozone amicable refrigerants have been produced to supplant refrigerants, for example, R-11, R-12 and R-22 to give some examples. Non-ozone exhaustion refrigerant, for example, R-410a has been utilized as a part of more up to date air conditioning frameworks.


  • 1820 Ice was first misleadingly made as an examination.
  • 1824 Michael Faraday found the standards for the retention sort of refrigeration.
  • 1834 Jacob Perkins created the primary simulated ice producing machine which prompted our present day pressure frameworks.
