Summary

This study presents a novel domestic refrigerator-freezer refrigeration cycle (NRFC), in which two ejectors and an internal heat exchanger are employed to enhance the refrigeration performance. The theoretical investigation using environmental friendly refrigerant R600a has been carried out, the simulation results show that the NRFC exhibits higher coefficient of performance (COP) and larger cooling capacity than the conventional refrigerator-freezer cycle (CRFC) and single ejector enhanced refrigerator-freezer cycle (ERFC). Under the given operation conditions, it is found that the COP and refrigeration capacity could be improved by 22.1% and 32.0% over the conventional refrigerator-freezer cycle, respectively. The performance characteristics of the novel cycle show its potential practical advantages in domestic refrigerator-freezer systems.
