This paper describes the engineering effort and method of manufacture used to build 36 high efficiency, automatic defrosting refrigerator-freezers. This work was undertaken as Phase II of a Department of Energy sponsored project to develop and test market a refrigerator-freezer of the automatic defrosting type that represented the best current capability for energy efficiency. A national laboratory was the prime contractor for the project, with a research firm and a manufacturer serving as subcontractors for the research and development, design engineering, and manufacturing phases of the task. Phase I of this project, optimizing the design and proving it feasible, has previously been reported. Although the prototype model developed was a 16 ft/sup 3/ (453 1) refrigerator-freezer, there was agreement by all parties involved in the project that an 18 ft/sup 3/ (510 1) model would be better suited for the market test. Early in 1979, the engineering team involved in this project began the design work to produce this model.
