Analyses expérimentales et de coût d'un réfrigérateur/congélateur domestique consommant un kilowattheure par jour.

Experimental and cost analyses of a one kilowatthour/day domestic refrigerator-freezer.

Résumé

The goal for the project was to achieve an energy consumption that is 50% below the 1993 National Appliance Energy Conservation Act standard for 570 litre units. Based on discussions with manufacturers, a laboratory prototype was fabricated with vacuum insulation around the freezer, increased door thicknesses, a high-efficiency compressor, a low-wattage condenser fan, a larger counterflow evaporator, and adaptive defrost control. The resulting energy consumption was 0.928 kilowatt hours/day for an extra cost of approximately USD 134. This cost being too high, a second design was investigated that was more cost-efficient. The second unit eliminated the vacuum panel insulation and larger counterflow evaporator. The cost-improved design resulted in an energy consumption of 1.164kilowatt hours/day at a manufacturer's cost increase of USD 53.
