AIR CONDITIONING (1902)

CARRIER MAKES THE WORLD A MUCH COOLER COOLER PLACE TO LIVE

  

      Willis carrier (1876-1950) of buffalo, New York, developed the fundamental scientific theories of air conditioning. His first system was designed for use in a printing plant. Change in the temperature and the humidity of the plant were causing the ink nozzles to be out of line, which made color printing problematic. Carrier was assigned with the task of fixing this problem .his early system, which made use of spraying nozzles to cool and rather dangerous the air, was large, extremely expensive, and rather dangerous because it relied on the use of ammonia as a coolant. For a year, his machines were just used to cool machine, but when the potential to cool people spotted, they began to be installed in other commercial building, began such as offices, hostel, and hospital. He even went on to the place units in the United States senate and the white house air conditioning has made life more comfortable and led to greater economic activity in the summer months. It can also reduce death rates from heat related illness by up to 40 percent.

               
       Carrier refined his design Andin 1922 installed a system at a Los Angeles theater where conditioned air was fed in from the ceiling and exhausted at floor level. The carrier corporation continues to make and install air conditioning system all over the world.

      The ancient Romans tried to keep their buildings cool during hot weather by pumping water from aqueducts through the wall of their houses, whereas in Southeast Asia people huge wet grass mats over the windows to lower the temperature of the air inside. Modern air conditioning, which arrived in 1902, is the continuation of this rudimentary principle.
