The Impact and Influence of Refrigeration Technology
student materials
Prior to the introduction of refrigeration, iceboxes kept food from spoiling; however they were time consuming, requiring ice replacement several times a week and emptying of trays of water. Food was maintained only at moderate temperatures. In 1921, five thousand refrigerators were manufactured in the United States. This beginning eventually led to the replacement of the icebox. However, early refrigerators were expensive and unreliable, often requiring repairs on the average of every three months. Costing about six hundred dollars in 1920, the price of a low-end model refrigerator dropped to ninety dollars within twenty years. By 1934 sales exceeded one million units, and that number was more than tripled by 1941. General Electric was the first manufacturer to design and market a hermetically sealed motor and to sell the box as an integral part of the refrigeration machinery. An author referred to the General Electric Monitor Top refrigerator, introduced in 1927, as “the Model T of the [refrigeration] industry.”
The refrigerator gradually evolved from being a luxury item affordable only by the wealthy, to being an affordable and reliable part of the modern kitchen. It was an invention that impacted many aspects of society, contributing to the transition to a consumer society. General Electric of Schenectady, New York, by introducing this enclosed and relatively inexpensive refrigerator, used science and technology to bring change to society. As a business corporation, General Electric produced vast amounts of historical documents that document this contribution.
