Helpful Refrigeration Resources for New DOE/AWEF and SNAP Regulations
July has brought some very important regulations that will impact the refrigeration industry. Below you will find links to important resources regarding:
–As of July 10, 2020, according to Department of Energy (DOE) regulations, all newly manufactured low temperature condensing units, low temperature self-contained units and both medium and low temperature unit coolers must meet minimum Annual Walk-In Energy Factor (AWEF) values.
–The Environmental Protection Agency (EPA) made certain HFCs unacceptable to use as part of its Significant New Alternatives Policy (SNAP) Rules 20 and 21. While a federal court later partially vacated these Rules, some states, including New Jersey, have chosen to adopt and implement the SNAP Rules. This means that as of July 1, 2020, in New Jersey, R404a refrigerants (the most popular refrigerant in refrigeration application) can no longer be used in many new and retrofit applications, other than cold storage warehouses.
Please reach out to your ABCO Refrigeration Team with any questions or for more information.
Department of Energy’s Annual Walk-In Energy Factor (AWEF) Regulations Impact Commercial Refrigeration
July 10, 2020 is the official compliance date for evaporators, including low temperature condensing units, low temperature self-contained units and both medium and low temperature unit coolers, to meet minimum AWEF standards. Heatcraft has summarized the recent DOE regulations and has also provided tips on how to best prepare for these changes.
HFC Regulations Fact Sheet
Chemours has created a Guide to Federal and State HFC Regulations in North America for HVACR Refrigerants. The Guide includes an HFC Regulations Fact Sheet as well as information about the Significant New Alternatives Policy (SNAP) in New Jersey.
