The history of air conditioner 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. As a result of the development in food refrigeration, other applications that follows include air conditioning, humidity control and manufacturing processes.
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 in the year 1842 by a physician named John Gorrie.
The commercially available of air conditioning applications started based on the need to cool air for industrial processes than for personal comfort. The first electrical air conditioning was invented by Willis Haviland Carrier in the year 1902. He was also known as the Father of Modern Air Conditioning.
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.
The Carrier Air Conditioning Company of America was established by him to meet the demand of better productivity in the workplace. Today, Carrier Corporation is the biggest air conditioner manufacturer and marketing corporation in the world in central air conditioning.
The discovery of Freon in 1928 by Thomas Midgley, Jr., a safer refrigerant to humans compared to the toxic and flammable gases such as ammonia, propane and methyl chloride sparks the invention of air conditioning systems for residential, industrial and commercial applications.
Unfortunately, the use of CFC and HCFC refrigerants are causing the depletion of ozone layer in our atmosphere that is causing harmful rays to penetrate our earth. Newer ozone friendly refrigerants have been developed to replace refrigerants such as R-11, R-12 and R-22 to name a few. Non-ozone depletion refrigerant such as R-410a has been used in newer air conditioning systems.
