The History Of The Refrigerator

Before iceboxs were produced, people were forced to cool their food with ice, snow,or nearby rivers and springs. Most people also had to can, salt, and locating their food to preservetheir meals. During these eons, inventors were working towards the creation of the icebox.In 1758, Benjamin Franklin experimented with the effects of evaporation on temperature. Withthe help from chemist John Hadley, both men were able to capture a way to drop thermometers temperature below freezing. Franklin and Hadleys work was soon picked up by the Americaninventor, Oliver Evans.Using principles drew up by Franklin Evans drew the physique for arefrigerator in 1805. Jacob Perkins modified Evans design and built the first practicalrefrigerating machine in 1834. Soon after, John Gorrie utilise Evans design to build a refrigeratorto make ice to cool the air for his yellow fever patients in 1844.Over 30 long time afterward Germanengineer Carl Von Linde discovered the process of liquefying gas which is part of basicrefrigeration technology. From the 1800s until the 1920s, refrigerators usedtoxic gases asrefrigerants. With research developed, corporations discovered a less(prenominal) dangerous refrigerantcalled Freon. Freon soon became the standard for almost all home kitchens.Carl Von Linde was born in 1842 and was the son of a Lutheran minister.He studiedscience and engineering at the Federal Polytechnic in Zurich, Switzerland. His research led to thedevelopment of the first compressed-ammonia refrigerator. In 1917, Linde formed the UnionCarbide and Carbon Corporation.On January 1, 1913, the first electric refrigerator in the United States was invented byFred W. Wolf. The refrigerator was an air-cooled refrigeration unit mounted on top of an ice boxand was called the Domelre. Exactly two years after the Domelre was created, the first self-container refrigerator was built by the Guardian Refrigerator Company.The company struggledand produced less than 40 appliances in two yea rs. The company was purchased by ordinaryMotors and the business was renamed Frigidaire. In 1918, the first Frigidaire refrigerator wasproduced. There were more than 200 different refrigerators on the market by 1920. Ice creamcabinets were added to models in 1923, carbonated water fountain equipment in 1924, and water and milkcoolers in 1927.One million refrigerators were produced by 1929. In 1947, GE was the firstcompany to introduce the two-door refrigerator-freezer combination. By 2005, 99.5 percent ofhomes had refrigerators.The refrigerator has changed the mankind in many ways. We are now able to preserve ourFoods such as fruits and vegetables for longer periods of time and beverages are now able to bekept cool. Without refrigeration, medicines and vaccinations would not have been able to bedeveloped. Refrigeration is also used for air conditioning in homes, public places and largewarehouses.Even those beautiful Valentines Day roses would not be able to be deliveredwithout re frigeration. Just imagine school without air conditioning, everyone would smellhorrible from sweating all day. Everyones darling ice creams would not have been createdwithout the freezer. Long car rides would be dreadful without an air conditioner.Refrigerators use refrigerants to carry heat away from the inside of the fridge. This isdone by injecting the refrigerants into a tube inside the refrigerator in liquid form and it slowlybegins to vaporize. Taking heat away makes the temperature cooler. When the liquid is donevaporizing, it travels to a roll on the outside of the fridge where it releases heat and becomes aliquid again. The process starts over again.After researching the history of the refrigerator, I have learned how much it has impactedthe world and how much people take it for granted. I would have never been able to enjoy myfavorite ice creams or drinks if it was not for the refrigerator. I would not be able to preserve myfavorite foods or keep my fruits and veggies fr esh.My favorite Eleven slushies would not evenexist. Some people do not take the time to realize the importance of the refrigerator and howmuch of a difference it has made in America.
