Hannaford Supermarkets opened a store in Turner, Maine, featuring the first transcritical (TC) carbon dioxide supermarket refrigeration system in the United States. The two-year-old, 35,000 ft2 (3252 m2) new-construction supermarket includes conditioned and refrigerated merchandising space, as well as food preparation areas and offices. The TC CO2 refrigeration system serves a total of 740 kBtu/h (217 kW) of combined low- and medium-temperature loads, while providing high-quality waste heat that meets much of the store’s space heating needs.
