Transcript of The Invention of the Refrigerator

The Invention of the Refrigerator The refrigerator has become a necessity to our daily lives. It was an invention that started out simply as an ice box and transformed to more sophisticated forms that you see today. The evolution of the refrigerator currently continues as our technology, along with our refrigeration needs, increases. Intro Background In earlier times, most people resorted to pickling, canning, and salting their food in order to preserve it. Some would rely on the cool river waters to keep meat cold, while others collected snow in the winter months to create snow packed cellars. Spoiled food lead to illness and more frequent deaths. Only the privileged had access to an "ice house", for example
Benjamin Franklin. Franklin grew tired of having to repeatedly stock the ice house and collaborated with others to seek a solution.
1758: Working with chemist John Hadley, Franklin experimented with the effects of evaporation on temperature. By repeatedly swabbing ether on a thermometer and allowing it to evaporate, they were able to get the temperature to drop below freezing. 1805: American Inventor, Oliver Evans, built his experiments
on the previous works of Hadley and Franklin to develop a design for a refrigerator. Evans, however, was busy with other inventions to actually create the design. 1834: Evan's friend, Jacob Perkins, received a patent
for the refrigerator using Evan's designs with a few of his own
modifications. Evan's then found a man named John Hague to construct
his designs and the refrigerator was born. 5 w's by: Amy Baird Who: people, consumers.
What: Refrigeration device.
When: 1750s- now.
Where: Everywhere.
Why: To preserve food and drink products. Also for convenience. Brainstorming Method(S) Modified integrated problem solving: The problem was stated and The invention of the refrigerator went through several series of modifications and a collaboration of ideas to get a final product (written and verbally). Electronic brainstorming is probably
more prevalent now for additions to the refrigerator. People may have suggestions for improvement via online message boards or customer complants through the appliance company. For the next hundred years, people would use Perkin's model of the refrigerator not knowing it was using potentially dangerous substances such as ether and ammonia to function. The refrigerator needed a few more modifications and is now what you have in your homes today. Evaluation Method The production of the refrigerator has gone through a series of "trial and error" evaluation. The invention designs have been modified and adjusted based on issues such as size and chemicals being used. References Atteberry, J. (n.d.). HowStuffWorks "Who invented the refrigerator?".
