When was the refrigerator patented

Even Albert Einstein himself tried his hand at contributing to the fridge and made a model in which had moving parts and did not rely on electricity. Commercial refrigeration came into popularity at the end of the 19th century due to the rise of breweries.

From there, they moved into more and more places. It was common to see a fridge in a situation like a meatpacking factory or any other commercial food production facility. By the s, the fridge was an essential item in the home of people everywhere. Naturally, this spread to places all around the world and culminated in the appliance we see and work with every day. Interestingly enough, the fridge has not changed in regards to the way it behaves and works — the basic premise of evaporating liquids remains throughout.

The chemicals are explicitly made to react at lower temperatures and are used to help you to keep your foods fresh.

The process works by pushing the liquids through the fridge via tubes, and exposure to the lower temperatures causes them to evaporate. The new gases carry heat with them to a coil which is outside of the fridge, which allows the heat to escape. As of , compressor refrigerators were still the most common, though some countries have made efforts to phase out the use of chlorofluorocarbons. Some machines now use alternative refrigerants such as HFOyf that are not as harmful to the atmosphere.

There even exist refrigerators that operate using solar, magnetic, and acoustic energy. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. Select basic ads.

Moore's device would now be called an "ice box" -- a cedar tub, insulated with rabbit fur, filled with ice, surrounding a sheetmetal container for transporting butter from rural Maryland to Washington, DC.

In the 18th century, Europeans collected ice in the winter, salted it, wrapped it in flannel, and stored it underground where it kept for months. When ice wasn't available or practical, people used cool cellars or placed goods underwater, according to History magazine.

Others built their own ice boxes, according to Keep It Cool. Wooden boxes were lined with tin or zinc and an insulating material such as cork, sawdust, or seaweed and filled with snow or ice. The concept of mechanical refrigeration began when William Cullen, a Scottish doctor, observed that evaporation had a cooling effect in the s.

He demonstrated his ideas in by evaporating ethyl ether in a vacuum, according to Peak Mechanical Partnership , a plumbing and heating company based in Saskatoon, Saskatchewan.

Oliver Evans, an American inventor, designed but did not build a refrigeration machine that used vapor instead of liquid in In , English scientist Michael Faraday used liquefied ammonia to cause cooling. Jacob Perkins, who worked with Evans, received a patent for a vapor-compression cycle using liquid ammonia in , according to History of Refrigeration. For that, he is sometimes called the "father of the refrigerator. John Gorrie, an America doctor, also built a machine similar to Evans' design in Gorrie used his refrigerator, which created ice, to cool down patients with yellow fever in a Florida hospital.
