Making Sense of the DOE’s Final 2017 Walk-In Efficiency Regulation

The Department of Energy (DOE) recently issued its final ruling on the regulation of energy consumption in walk-in coolers and freezers. The ruling is based on the Annual Walk-In Energy Factor (AWEF) rating for refrigeration systems and components, and adopts the industry testing protocol AHRI 1250 as its metric of enforcement. To comply with the ruling’s June 5, 2017 effective date, manufacturers of walk-in coolers and freezers will need to begin evaluating energy efficient components and technologies today.

Of particular interest to OEMs is the effectiveness of condensing unit technology and how it measures up to the AWEF’s ratings. Manufacturers will also have to consider every available design option — such as compressors, coil, motors, modulation and controls — to prepare systems for compliance in 2017.

To address the myriad concerns and considerations of the DOE 2017 ruling, Emerson Climate Technologies is holding a new Making Sense webinar on Oct. 21 at 2 p.m., entitled Staying Ahead of the DOE 2017 Walk-in Cooler and Freezer Energy Efficiency Ratings. This complementary live event will explore the far-reaching implications of the DOE rule, and discuss the following topics:

  • Survey of existing condensing unit technology and how it compares to the AWEF minimum requirements
  • Technology/design options (compressors, coil, motors, modulation, controls, etc.)
  • Importance of low condensing operation/floating head pressure
  • AWEF calculations for condensing units, unit coolers and complete systems
  • AWEF versus AEER
  • Impacts of the EPA’s recent significant new alternative (SNAP) refrigerant delisting proposal
  • Refrigeration industry push back

The webinar will be presented by two Emerson Climate Technologies experts who are most familiar with the subject: Ani Jayanth, foodservice marketing manager of the refrigeration division, and Brian Buynacek, refrigeration engineer. Ani has been very close to the DOE 2017 ruling for quite some time and has significant insight on its implications, and Brian will lend his expertise on AWEF and how it plays into the ruling. Join Ani and Brian on Tuesday, Oct. 21 at 2 p.m. EDT for this informative and timely webinar.
