View Rule

DOE conducted a rulemaking to consider new test procedures that would measure the energy efficiency of wine chillers and other related miscellaneous refrigeration products that maintain warmer compartment temperatures than refrigerators. These considered procedures were related to those products that use a vapor-compression refrigeration system and those that do not. DOE examined revising existing and establishing new definitions in addition to establishing new test procedures for: (1) cooled cabinets; (2) refrigerators that do not use a vapor-compression refrigeration system; and (3) hybrid (or "combination") refrigeration products, which incorporate warm compartments such as wine storage compartments in products that otherwise provide the functions of refrigerators, refrigerator-freezers, or freezers. DOE recently finalized a rule establishing a test procedure for these miscellaneous refrigeration products. That rule also amended certain definitions to eliminate any potential confusion with new terms that are being added as part of that procedure.
