The U.S Department of Energy (DOE) has published a final rule in the Federal Register in the certain equipment classes of walk-in cooler and freezer (WICF) refrigeration systems — 82FR31808 (July 10, 2017).  The DOE is adopting energy conservation standards for the following classes of WICF refrigeration systems: low-temperature dedicated condensing refrigeration systems and both medium- and low-temperature unit coolers. The standards published in the final rule were the results of a negotiated rulemaking that included refrigeration system manufacturers, installers, utilities, states, and energy efficiency advocates.

  • The effective date of this rule is September 8, 2017.
  • Compliance with the standards established for certain WICF refrigeration systems equipment classes addressed in this final rule is required on and after July 10, 2020.
