In the last quarter of the century, a substantial amount of research work has been conducted on optimization of energy consumption by refrigeration systems and on proper design and construction of household refrigerator-freezers. The importance of such energy optimization schemes stems from the environmental impacts of Freon (R-12) used as the working refrigerant in household refrigerator – fre...
