History of the Refrigerator Essay 1179 Words 5 Pages History of the Refrigerator Back in time a long time ago, around 500 B.C. the Egyptians and Indians made ice on cold nights by setting water out in earthenware pots and keeping the pots wet.
The refrigerator has also been an economical product. People are able to purchase food in bulk amounts, without the worry that something will spoil. The refrigerator is a great invention that many people could not live without, and we should all show appreciation to Jacob Perkins, the inventor of the first practical refrigerating machine.
Invention of the Refrigerator. There were more than a few inventors that filed patents for the invention of the refrigerator. In fact, by the year 1880 there were over 3000 patents for refrigerators. People used boxes filled with ice (iceboxes) to keep their food cool and keep it from spoiling. Iceboxes were lined with metal and insulated with.
The refrigerator is such an important component of modern life that it is hard to imagine what the world was like without it. Before mechanical refrigeration systems were introduced, people had to cool their food using ice and snow, either found locally or brought down from the mountains.
A refrigerator (colloquially fridge) consists of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the room temperature. Refrigeration is an essential food storage technique in developed countries.
The modern refrigerator is a recent invention. Refrigeration is the process of creating cooling conditions by removing heat. It is mostly used to preserve food and other perishable items.
History. Frigidaire began mass producing electric refrigerators in 1918, and by the 1930s the name was synonymous with the appliance. Early to mid-20th century refrigerator technology involved passing coolants such as ammonia and freon through a circuit from a condenser to an evaporator circuit to draw warm air away from the refrigerator cabinet.
A refrigerator is a machine that freezes or cools food or drinks in order to preserve them. The refrigerator is an important invention as it allows humans to store food for longer periods of time which gives them access to a potentially healthier and well-balanced diet.
The Evolution of the Refrigerator Technology Refrigerator preserves food by maintaining it at a near freezing temperature which prohibits breeding of microbes and thereby preventing food spoilage. Refrigerators work on the second low of thermodynamics.
Another prolific American inventor, Oliver Evans, would take the principles developed by Franklin and others and draw up a design for a refrigerator in 1805 (source: Haley).Evans' first love, however, was the steam engine, so he set his plans on ice while he spent his energy developing things like a steam-powered river dredger.Thankfully, however, Evans' design didn't go to waste.
