Styled with modern curved line and form, this cooling unit reflects the Art Deco influences of the mid 1930\u2019s. Of special note is the built in temperature control and on-off switch, conveniently place for the homemaker. The control is equipped with a manual, reset overload switch by Ranco, a leading innovation in control technology for the times<\/p>\n\n\n\n

The technological significance of the evaporator in a mechanical refrigeration system lies in its ability to evaporate liquid refrigerant (allowing it to absorb latent heat and thus perform useful cooling). In the public mind, however, the useful work was more simply that of cooling. This lead astute manufactures to popularise the use of the term \u201ccooling unit\u201d in place of evaporator. It was the term adopted by the industry in the early years, as it attempted to connect with the human experience of the times to better promote its wares, gaining market share in the embryonic years of Canada\u2019s emerging consumer society. (See examples in early sale literature from the Kelvinator Co. of Canada)
Human experience and the social culture of the 1920\u2019s also associated useful cooling with the melting of ice. Historically manufactures successfully played to this sense of public understanding by further marketing cooling units as icemakers. By this means they appealed to wide spread cultural understandings of how things got cooled, through the controlled melting of ice (the popular Canadian icebox of the 1920\u2019s and 30\u2019s). In a peculiar twist, it was often the job of the refrigeration sales or service man to explain to the homemaker that it was not really the ice in the ice cube trays that cooled the refrigerator, but the motor and compressor underneath.
In the 1920\u2019s manufactures of mechanical refrigerators for the home appealed to the consumer public by promoting ice and ice cream as the new consumables, the new food sensations available for all those sufficiently affluent to enjoy the experience. Promotional literature focused on the pleasant sensation of ice cold beverages and on ice cream making at home \u2013 using the latest cooling unit. A recipe and food life style book came with the refrigerator for the edification and instruction of the homemaker (See examples in early sale literature from the Kelvinator Co. of Canada). Ice and ice cream making in the home was, in fact, one of the significant, new \u201cGee whiz\u201d, household technologies of the times.
This specimen is a remarkable icon of its time, marking a dramatic change in engineering, manufacturing and styling, as the industry geared up to move beyond its embryonic development years. Of particular note, technically, is the inclusion of an automatic overload device, with manual reset. This was representative of the early years of safety control technology designed for equipment protection and personal safety.<\/p>\n\n\n\n
With the mid 1930\u2019s came increased competition in the refrigeration appliance field, as companies such as Borg Warner and General Motors\/Frigidaire, with significant engineering and production experience and resources behind them made major investments in the now rapidly expanding field.<\/p>","protected":false},"excerpt":{"rendered":"
