Title: Simulation Results of Single Refrigerants for Use in Dual-Circuit Refrigerator/Freezer
Abstract: Dual-circuit RFs have been shown to have a theoretical advantage over single-evaporator RFs if the compressor efficiencies of the separate loops are equivalent to the compressor efficiency of the combined system. Single refrigerants were analyzed to determine the optimum pure refrigerant in each of the two separate freezer and fresh food loops. R-152a and R-142b were determined to be the optimum single refrigerants in the dual-circuit system. With the assumptions made, theoretical energy savings of up to 23% of compressor power are possible.
