Abstract
There are approximately seven million refrigerator-freezers in the State of Florida. The average demand of these units is at least 1,000 MW. The average life of a residential refrigerator is approximately 20 years (U.S. DOE, 1989). At least 25% of Florida's existing stock are old inefficient units built before the advent of recent appliance efficiency standards. The least efficient are existing models of which approximately 5% of the stock is replaced each year. This represents a significant opportunity for efficiency improvement since recently established standards will greatly improve refrigerator efficiency by 1993 (NAECA, 1987). A number of studies have identified technologies that can dramatically improve the efficiency of new refrigerators (Turiel and Heydari, 1988; U.S. DOE, 1989). As example, one analysis found that the annual electrical consumption of an 18 cubic foot refrigerator-freezer could be potentially reduced by 46% to only 515 kWh through the use of improved insulation, high efficiency compressors and fans and adaptive defrost (Turiel et al., 1990). In order to better define this potential, the Florida Solar Energy Center (FSEC), has conducted a case study of the potential of replacing an existing refrigerator with an energy efficient model to both save energy and alter utility load shape. We also analyzed a database of all available refrigerators manufactured in the U.S. in 1991. This statistical analysis examined differences in refrigerator size and how they may influence annual estimated energy use. Such information may be useful for utility Demand-Side Management (DSM) planners who wish to realize savings from high-efficiency refrigerator programs.
