DEVELOPMENT OF ENERGY EFFICIENT ELECTRICAL HOUSEHOLD APPLIANCES. PART ONE - REFRIGERATORS
The objective of the part of the project described in this report was to develop and build a prototype of a low energy refrigerator, consuming only about one fifth of the electricity consumed by a typical 1975 refrigerator. The work reported here is based on earlier analyses indicating electricity saving potentials, and undertakes to design and build low energy refrigerator prototypes. The project was carried out in cooperation with the refrigerator manufacturer Brdr. Gram. Improved compressors were provided by Danfoss. A 200 litre low energy refrigerator with no freezer compartment was designed. A few prototype cabinets were built with improved insulation, improved compressor and improved evaporator and condensor. The system is automatically defrosting. Electricity consumption was found to be 102 kWh/year, about 20 percent of what a typical 1975 refrigerator of same size consumes. Although the target was thus reached, experimental tests indicated that further reduction in electricity consumption is possible through a better adapted compressor, better control systems etc. No ideal solutions have as yet been found, but the work continues.
