History of Air Conditioning

History of Air Conditioners/Conditioning:

• 1820 Ice was first artificially made as an experiment.
• 1824 Michael Faraday discovered the principles for the absorption type of refrigeration.
• 1834 Jacob Perkins invented the first artificial ice manufacturing machine which led to our modern compression systems.
• 1902 Willis Haviland Carrier invented the first air conditioner to control the temperature and humidity of a printing company, marking the first time effort taken to control the temperature of the surroundings. This starts the history of air conditioning.
• 1906 Stuart W. Cramer come out with the term "Air Conditioning." which was later adopted by Carrier.
• 1913 The first international refrigeration expo is held in Chicago.
• 1928 The discovery of Freon refrigerant by Thomas Midgley, Jr.
• 1930 The White House is air-conditioned.
• 1946 The demand for room air conditioners began to increase with more than 30,000 units produced on this year.
• 1953 Room air conditioners sale exceed 1 million units. This is another key milestone in the history of air conditioner.
• 1953 The Refrigeration Equipment Manufacturers Association and The Air-Conditioning and Refrigerating Machinery Association are formed.
• 1957 The first rotary compressor was developed hence making air conditioning units smaller and more efficient compared to the reciprocating type.
• 1977 Heat Pumps equipment developed that allows cooling and heating cycle using the same machine that can be used to provide cooling during summer and heating during winter.
• 1987 Montreal Protocol signed to protect the earth's ozone layer is signed in Montreal, Canada. The Protocol establishes international cooperation on the phase out of ozone depleting substances, including the chlorofluorocarbon(CFC) refrigerants used in HVAC equipment.
• 1990 Microprocessor control systems are used in all areas of refrigeration and air conditioning due to the readily available semiconductor technology.
• 1992 The R-22 Alternative Refrigeration Evaluation Program (AREP) starts to find alternative refrigerants to R-502 and R-22.
• 1995 Chloroflourocarbon (CFC) manufacturing in the USA ends on December 31.
• 1997 Kyoto Protocol signed to protect the earth's climate by reducing greenhouse gases that cause climate change.
• 1998 Unitary air conditioners and heat pumps set a sale record of more than 6 million units.
• 2007 A State Council issued a circular to restrict the temperature of air conditioning in public buildings to 26°C (78°F) or higher during summer and 20°C (68&decF) and lower during winter. Sale of low efficiency air conditioning units are also outlawed.
