Description:

A two-cycle 18 ft3 (0.51 m3) refrigerator/freezer (R/F) was tested utilizing American National Standards Institute (ANSI)/AHAM (1988) standards for energy consumption testing. A 34.9% energy consumption reduction was realized. This work presents a proven method of reducing the current Department of Energy (DOE) minimum energy efficiency standards for R/F to the proposed year 2001 standards. For a top-mount frost-free R/F having the above volume the current DOE minimum energy standard is 770 kWh/year, and the proposed year 2001 standard is 530 kWh/year. This is a 31% reduction which may be obtained by implementing the modifications discussed in this paper. The paper gives an overview of the modifications implemented by the University of Denmark on an American R/F and presents experimental performance testing results of the R/F. The R/F was tested using four refrigerants and compressors. Two compressors and refrigerants were tested in the freezer cycle, and four were tested in the fresh food cycle.
