Summary
For several years, refrigerators have been submitted to laboratory tests in an effort to determine the appliance's typical annual energy consumption and the cost of that energy to the consumer. The standard test procedure, developed by the US Department of Energy, has been criticized for inaccurately reflecting the actual home use of a refrigerator, and thus for producing energy ratings that are unrepresentative. The Bonneville Power Administration (BPA) needs accurate estimates of electric power usage by refrigerators for forecasting and for evaluating the conservation potential of high-efficiency appliances. Prior to embarking on an independent field study, an in-house literature review was conducted which revealed that several field studies of refrigerator performance have been completed. Compilation and analysis of those data indicate that the findings are relatively consistent. On the average, rated refrigerators consume 5% more energy during home use than predicted in laboratory tests. When segregated by design efficiency, the energy consumption of the high efficiency model is very close to the rated value; while conventional design models consume about 10% more than the rating. Overall, refrigerators used in warm climates consume more power than those in cool climates. In the Pacific Northwest, the average refrigerator can be expected to use slightly less electric power than its rating. A more accurate assessment of consumption for refrigerators in the BPA area will be determined by the End-Use Load and Conservation Assessment Program (ELCAP).
