Refrigerating and Air Conditioning Condensing Units – Household
A smoothly designed mid 1930’s, coil spring mounted medium speed, condensing unit with belt driven, single cylinder, reciprocating compressor, copper tube and finned, single pass air cooled condenser with 3 lb refrigerant receiver, with 1/6th HP electric motor, and a new generation of quiet 3 blade cloverleaf fan. The machine by Universal Refrigeration, demonstrates their special contribution to the design and production of refrigerating machines in Canada, in what was quickly becoming an increasingly competitive market segment, Universal Cooler Brantford Ontario, 1936.
This refrigerating machine is equipped with a new style, for the period of condensing air cooling fan. The clover life design evoved as a quieter more efficient blade than the simpler straight cut propeller type of an earlier generation of condensing units in Canada.Whether this blade was original or installed, as part of a subsequent up-grade is unknown. Air noise in the family kitchen was an on-going irritation and refrigeration mechanics would do what they could to minimise it, in the interests of good customer relations and product satisfaction
Technical Significance:
One of an early breed of Canadian made condensing units [along with Kelvinator of Canada] moving from the use of highly noxious SO2 to methyl chloride, heralding the massive swing to the chlorinated hydrocarbon refrigerants by the end of the decade (F12).
Industrial Significance:
Demonstrates the craftsmanship, manufacturing methods and breadth of design and manufacturing options being explored by Canadian refrigeration manufacturers by the mid 1930’sWestern Ontario was fast becoming the heartland and Mecca for refrigeration design and manufacturing in Canada.
