ARTIFICIAL REFRIGERATION IN THE NINETEENTH CENTURY.

By the middle of the 19-th century engineers had designed and built practical artificial refrigeration machines, though their slow-speed, oversized, and even hand-operated equipment appears, in retrospect, somewhat ridiculous. The earliest recorded patent for a refrigeration machine was issued in Great Britain in 1790 to Thomas Harris and John Long. A few years later Jacob Perkins, an American, patented the machine consisting of a hand-operated compressor, a water-cooled condenser with a weighted valve at the discharge and an evaporator contained in a liquid cooler. The unit was designed to be used with ether as the refrigerant.

There were many other nineteenth-century pioneers in refrigeration. In 1851 Dr.John Gorrie of Florida obtained the first American patent for an ice machine, designed to use compressed air as the refrigerant. As a physician he was motivated by a desire to relieve the sufferings of fever patients and other exposed to high temperatures. Professor A.C.Twining of New Haven developed a sulfuric ether machine that preceded Gorrie's; however, he failed to have it patented in the United States until 1853. Dr.James Harrison of Australia also developed a sulfuric ether machine and in 1860 made the world's first installation of refrigerating equipments in a brewery. In 1861 Dr.Alexander Kirk of England constructed a cold-air machine similar to Gorrie's; it is said to have consumed one pound of coal for each four pounds of ice produced.

Ferdinand Carre introduced absorption system to the Confederate States from France during the Civil War. The need for refrigeration had become acute, since the supply of natural ice from the North had been cut off. This was the first heat-operated absorption system and consisted of an evaporator, condenser, generator, pump, and absorber. This unit was designed to operate with ammonia as the refrigerant and water as the absorbent.
