Unitary Refrigeration Equipment: The idea of a unitary piece of refrigeration or air conditioning equipment was a significant one in its own right, one that had to wait its time. The scientists, engineers and inventors in the early years of the 20th century were intrigued and obsessed with the power of the technology and of its possible market potential. What they saw was the newly discovered principles of physics and heat engines \u2013 following, for example, the early works of Carnot, Faraday, Kelvin, and the later work of Perkins, Larsen and Carrier, to name a few. They understood the promise of the technology for the public good, not to say its consumer sales potential. Early engineering work advanced on a multiple fronts with development of compressors, heat exchangers, valves and piping variously strung together in configurations that would be found to work, but only after much experimentation.
The arrival of unitary equipment, all those parts organised into a single whole, a single unit of construction, a \u201cblack box\u201d, that could be offered to the consumer market was a significant technological and cultural event. Technologically the refrigerator would need to be seen to be safe, reliable, maintainable and useful. As well, in order to attract the development capital needed, it must be seen as potentially saleable and affordable, contributing to life\u2019s needs and desires. Its socio- cultural and economic significance was marked, for it would change much. As Canadians we would quickly come enjoy potentially healthier lives, expect new levels of comfort and convenience, with a broader, safer, more diverse and enjoyable diet.
As a result, Canadians would quickly come to think of their day differently, for the day would be defined and punctuated in different ways than ever before, as a result of the introduction of modern, electric, household appliances, of which refrigerators, freezers and room air conditioners would be a central part, by the mid 20th century
J. M Larsen produced a manually operated household refrigerator of sorts in 1913, but it was not until 1918 that the Kelvinator Company marketed the first automatic, unitary refrigerator for the home. In that year, it is reported to have sold sixty-seven machines. (See Note 1) The historic artifacts in Group 1.00, Unitary Equipment, including significant samplings the early work of Kelvinator of Canada, provide a rare view of the evolution of unitary refrigeration and air conditioning applications, as they evolved in Canada in the first half of the 20th century.
For those formative years, the artifacts in this Group, 1.00, are typical of the offerings of the Canadian refrigeration and air conditioning industry. They personified the applications found in the homes, farms and commercial premises of the period for, those that could afford life\u2019s new amenities of comfort, convenience and privilege.
This Specimen: is an example of a particular genre in the evolution of two temperature refrigeration system engineering for the household. Although the engineering design adopted here would be relatively short lived, it represented a major advance in refrigeration engineering, allowing a full two temperature refrigerator in a single cabinet, with single condensing unit. A a simple, transitional technology, the use of two static evaporators, operating at different temperatures was a major step in the evolution of the home refrigerator.
The advent of the two-temperature refrigerator, one in every kitchen of the nation, would be a goal of the industry, one largely achieved well before the end of the century. The impact on the way Canadians lived and their expectations for daily diet and life style was significant- for it was the \u201cTV dinner\u201d era had arrived along with the TV in the living room and the refrigerator freezer in the kitchen.<\/p>\n\n\n\n
An excellent example of the impressive Canadian manufacturing facilities for major appliances that developed in the 1950 to 60 in Ontario, prior to changing markets and increased competition leading to down-sizing, consolidation and globalisation of the industry. This is an icon from the golden age of Canadian appliance manufacturing. The changing market would soon see the demise of Kelvinator of Canada as the pioneer in refrigeration manufacturing in Canada. During the early post WWII years Kelvinator sought to build production capacity in its London Ontario plant by manufacturing for other, \u201ccome lately\u201d companies, looking for a share of the post war boom market \u2013 such as General Steel Wares and Admiral.<\/p>","protected":false},"excerpt":{"rendered":"
