Summary

A dual-loop cycle for a domestic refrigerator-freezer (RF) has a large energy saving potential because of lower compression ratio due to higher evaporating temperature in the fresh food compartment (R)-operation, and the individual optimization flexibility for each loop, compared to a conventional refrigeration cycle. In this study, the optimization of the dual-loop cycle was carried out. The optimization process included both the theoretical analysis and experimental investigation. The theoretical analysis was conducted to optimize the specifications of cycle components for each loop of the dual-loop cycle. Based on the experimental results, the energy consumptions of the optimized dual-loop cycle was decreased by 14.2%, compared with that of a bypass two-circuit cycle in the same RF platform.
