Engineering and manufacture of a high-efficiency, automatic defrosting refrigerator-freezer
The engineering effort and method of manufacture used to build thirty-six high efficiency, automatic defrosting, refrigerator-freezers are described. It was determined that an 18 ft/sup 3/ model would be suited for the market test. Calculations were made to establish its physical size and insulation thicknesses were specified. The heat leaks were calculated using a computer program and the calculation established the expected heat flow when operated in a 90/sup 0/F ambient with a 5/sup 0/F freezer and a 38/sup 0/F fresh food compartment. The program was also used to determine expected performance when various refrigeration system components and configurations were considered. The engineering design and the component selection are discussed. The sequences of prototype testing are followed.
