Jacoby Perkins, an American who works in Britain, made a new discovery, which led to the invention of the refrigerator. In 1834, he found that when some liquids evaporate, there will be a cooling effect. Perkins asked a group of technicians to make a working model that could prove the idea. Sure enough, this device really produced some ice in one night. The mechanics excitedly took the ice cubes, jumped into a carriage and hurried to Perkins' house to show him their achievements. Perkins was old at this time. He didn't sell his invention in the market. The seller of the invention lives in john harrison, an Australian Scottish printer. Harrison may have discovered the cooling effect without knowing Perkins' results. He cleaned metal type with ether, and one day he noticed the cooling effect of this substance. By 1862, his first refrigerator was on the market. Harrison also established the first refrigeration workshop in a brewery in Bendigo, Victoria. German engineer Karl von Linde made the first household refrigerator in 1879. But before the invention of refrigerators in the 1920s, refrigerators did not enter the home on a large scale.
