Office of Energy Efficiency and Renewable Energy May 26, 2017 – Federal Register Recent Federal Regulation Documents

This notice announces receipt of and publishes a petition for waiver from AHT Cooling Systems GmbH and AHT Cooling Systems USA Inc. (AHT) seeking an exemption from specified portions of the U.S. Department of Energy (DOE) test procedure for determining the energy consumption of commercial refrigerators, freezers, and refrigerator- freezers (collectively ``commercial refrigeration equipment'') under the regulations. AHT seeks to use an alternate test procedure to address issues involved in testing forty-eight basic models identified by AHT as part of its petition that do not have a typical defrosting cycle (i.e., the cooling coils are built into the body of the units and require defrosting once or twice per week). Consequently, AHT seeks to test and rate these basic models as ice cream freezers only and to use an alternate two-part test procedure to account for the infrequent defrosts. This notice also announces that DOE is declining to grant AHT an interim waiver regarding multi-mode operation, but DOE is granting an interim waiver to address the defrost cycles, with modifications to AHT's requested approach. DOE solicits comments, data, and information concerning AHT's petition and its suggested alternate test procedure to inform its final decision.
