I chose the technology of Refrigeration to think about twenty years from now. A refrigerator Is a common household appliance that consist of a thermally insulated compartment and a heat pump ( mechanical, electronic, or chemical) that transfers heat from inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room. A refrigerator is a common essential technology apart of our everyday living. It is extremely useful to keep food from spoiling by slowing down the rate of bacterial growth by staying a few degrees’ above the freezing point of water, as well as purifying water and creating ice. Refrigeration units have come a long way since their predecessor the ice box and before the ice was the ice house, which was basically a shelter dedicated to keeping food as cold as possible placed near a glacier run off, stream or anywhere seemingly to be the most ideal location. Since around 1913 when refrigeration units were made to mount on top of an ice box an essential part of living was being introduced to Americans. It was actually a year later when Nathaniel B. Wales of Detroit, Michigan introduced the idea of a practical electric refrigeration unit, which later became the basis for the Kelvinator and self contained refrigerator. Three years past the mounted ice box unit, inventor and philanthropist Alfred Mellowes improved his design model of the Kelvinator and added a compressor to the bottom of the cabinet. Soon Commercial refrigerators are ready to be sold to millions of Americans who will soon notice the convenience and worth of their own Frigidaire refrigerator appliance. Thus began a race of sorts to take technology of refrigeration to its peaks domestic and foreign. In 1918 the first automatic refrigerator unit was available by the Kelvinator Company; this was extremely popular for a few years until the absorption
