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 approving 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.
