View Rule

DOE is conducting 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. It is also considering establishing a test procedure for icemakers.  These procedures are being considered for those products that use a vapor-compression refrigeration system and those that do not. DOE is looking at new definitions and test procedures for (1) cooled cabinets, (2) refrigerators that do not use a vapor-compression refrigeration system, (3) hybrid refrigeration products, which incorporate warm compartments such as wine storage compartments in products that otherwise provide the functions of refrigerators, refrigerator-freezers, or freezers, and (4) ice makers.
