SALISBURY, N.C. — Food Lion here has observed a 2% to 3% reduction in energy consumption in a low-temperature secondary-loop refrigeration system, in comparison to the energy consumed by a standard DX refrigeration system, said Susan Sollenberger, Food Lion’s director of equipment purchasing, maintenance and energy. The secondary loop system, provided by Hill Phoenix, Conyers, Ga., is being tested at a Food Lion store in Montpelier, Va.

Food Lion is sharing data on the system as part of the Environmental Protection Agency’s GreenChill Advanced Refrigeration Partnership, which was officially launched this week in Washington. The secondary loop system uses carbon dioxide as a secondary refrigerant.
