Running head: REFRIGERATOR, HOW IT WORK (Student Name) (Instructor’s Name) (Course Name) 31st October 2013 Introduction One of the best technologies that human being has invented for food storage is the refrigerator. As the demand for food increase in the cotemporary world due to the increase in population, most countries have advocated for storage of food to avoid wastage.
This paper keenly discusses how refrigerator works as well as its history and associated design processes. Before the invention of the modern refrigerator, individuals used ice or snow to cool their food. One of the most known pioneers of the modern refrigerator was William Cullen. In 1748, Cullen invented the first refrigeration at the Glasgow University. Similarly, Oliver Evans, a renowned American inventor also contributed in the development of the refrigeration by inventing the vapor-compression refrigeration that was mostly used in 1805. The aim of this machine was to remove heat from substances by the process of recycling vaporized refrigerant. Another contributor in the early development of refrigerator was Jacob Evans. Through the use of vapor-compression, Evans invented the first refrigerator after making various improvements on Oliver designs. As the demand for the refrigeration increased, various scientists and doctors introduced other aspects that were focused at improving the refrigeration process. In 1913, Fred Wolf, introduced the refrigerators that were used in homes. This was followed by the introduction of a refrigeration unit in 1914 by Nathaniel, a well known engineer who was based in Michigan. ...
