Join us for our next E360 Webinar that will take a look at the latest refrigerant regulations impacting commercial refrigeration and AC applications on Tuesday, February 26 at 2 p.m. EST/11 a.m. PST for this informative update.

One of the greatest sources of uncertainty in today’s commercial refrigeration and AC industries is the topic of refrigerants. Regulations continue to evolve quickly, primarily aimed at phasing down the use of hydrofluorocarbon (HFC) refrigerants with higher global warming potentials (GWP), which are used in many applications. What’s particularly challenging is how these rules can differ from state to country to region, making it difficult to adopt a common standard.

Globally, these efforts are spearheaded by the Kigali Amendment to the Montreal Protocol, an international treaty in which participating countries are working toward a shared goal of HFC phase-down via mutually agreed upon timelines. In the U.S., the regulatory climate continues to be unpredictable, but states such as California are leading the charge on establishing regulatory standards.

With new updates taking place seemingly every month, it’s becoming increasingly difficult to stay informed. That’s why we’re dedicating our next E360 Webinar to clearing the confusion in this turbulent regulatory climate. This webinar will be hosted by Emerson’s leading experts on refrigerant regulations: Rajan Rajendran, vice president, systems innovation center and sustainability; and Jennifer Butsch, regulatory affairs manager, air conditioning. Jennifer will present the latest updates to the refrigerant rulemaking while Rajan will offer his extensive insights on how to prepare for what’s on the horizon.

Attendees will learn:

  • How recent rulings have changed the scope of the Environmental Protection Agency’s (EPA) Significant New Alternatives Policy (SNAP) program
  • How the California Air Resources Board (CARB) continues to leverage the original SNAP ruling as the foundation for its regional HFC refrigerant phase-down efforts
  • An update on the potential for U.S. ratification of the Kigali Amendment to the Montreal Protocol
  • Status of the standards governing charge limits and safe use of A2L and A3 refrigerants, including the potential impacts on building codes
  • How the vacating of SNAP Rule 20 potentially impacts Section 608 in terms of governing leak repair and maintenance requirements
  • Availability of new low-GWP refrigerants

Commercial Refrigeration Industry Prepares for Next Generation of Refrigerants

217-P-E360_Compass_ART5

The commercial refrigeration industry is at a crossroads. In one direction, the Environmental Protection Agency (EPA) is proposing to ban many commonly used refrigerants in favor of low-GWP alternatives. In the other direction, the Department of Energy (DOE) is mandating significant reductions in energy consumption for reach-ins, walk-ins and ice makers by 2017. If that wasn’t challenging enough, the two regulations at times conflict — with the DOE’s new standards based on the EPA’s delisted refrigerants.

Inaugural E360 Forum Provides Important Exchange of Information

We recently held our very first E360 Forum in Columbus, Ohio, to discuss the refrigeration challenges facing the foodservice industry today. Judging by the number of attendees and the tenor of the conversations that took place, it is clear that our industry is seeking an outlet to discuss the impending regulatory changes and offer insights on how refrigerated system design will be impacted in the near future.

The event was kicked off with an informative keynote address about foodservice trends and equipment by Robin Ashton, president and publisher of Foodservice Equipment Reports. Mr. Ashton informed attendees that refrigeration makes up the largest segment of equipment in the foodservice market, and that while operators are extremely concerned about the Department of Energy’s upcoming efficiency regulations, energy efficiency itself is still not among the most important considerations when selecting equipment. Ashton did, however, forecast an upward cycle for the foodservice equipment market over the next few years.

Emerson’s Dr. Rajan Rajendran then took the floor to discuss the volatile state of refrigerant regulations. Rajan provided a brief history of refrigerant evolution, initially introduced by the Montreal Protocol to lower global warming potential (GWP) with the phase-down of HFC-based refrigerants, and most recently driven by the European Union’s and the Environmental Protection Agency’s (EPA) motions to restrict GWP in refrigerants even further. In particular, the EPA will create a new ruling in 2015 as a part of its significant new alternatives proposal (SNAP) to delist some of the most common refrigerants in use today.

Rajan indicated that 404A will likely be delisted, and then explored what these changes mean to equipment design. Finally, he raised the question to which everyone is seeking an answer: “Which refrigerant will the industry use as a replacement?” While there is no one-size-fits all solution, the re-emergence of CO2, propane and other natural refrigerants, and the introduction of synthetic blends with similar pressure characteristics provide the hope for minimal system redesigns. Attendees were most concerned about the potential impacts to system design.

The two keynote addresses set the tone for the day’s remaining six breakout sessions. As topics ranged from retrofit strategies and meeting DOE energy compliance to CO2 system architecture and kitchen design trends, the regulatory landscape framed the discussions. Information was readily exchanged between moderators and attendees, and the event provided ample opportunities to ask questions and interact with peers. Clearly, not all questions could be answered and addressed in a day. But our intent to create an interactive dialogue to help define the path forward in refrigeration had been achieved

Our next E360 Forum will pick up the conversations where these left off. To be held at the Embassy Suites Anaheim — South on February 18 in Anaheim, California, these important discussions will take place in conjunction with the North American Association of Food Equipment Manufacturers (NAFEM) show starting on February 19. We hope to see you there. We need everyone’s contributions to help shape the future of refrigeration.

EPA Releases Proposed Timeline for HFC Status Changes

Earlier this year I reported the EPA’s intention to move on the delisting of certain hydroflourocarbons (HFCs) and HFC blends this summer. That process is now officially underway. On July 9, the EPA released the prepublication version of a Notice of Public Rule (NOPR) detailing proposed changes in listing status, tentatively scheduled to take effect as early as January 1, 2016.

The proposed rule is part of the Significant New Alternatives Policy (SNAP) program, which evaluates and revises acceptable alternatives to ozone-depleting substances (ODS) on an ongoing basis. A 60-day comment period for industry stakeholders begins once this NOPR is published in the Federal Register.

Key points in the rule include bans on R-404A and R-507A for new and retrofitted retail food refrigeration, including direct and indirect supermarket systems and walk-in cooler/freezer condensing units. It also proposes bans on R-404A, R-507A and HFC-134a in new, stand-alone refrigeration units and vending machines. Other blends to be delisted as unacceptable for direct and indirect supermarket systems include: HFC-227ea, R-407B, R-421B, R-422A, R-422C, R-422D, R-428A and R-434A.

These changes are intended to drive the market to refrigerants with lower global warming potential (GWP). In the near term, the industry will move toward already-tested, available alternatives, such as R-407A, carbon dioxide (CO2) or R-290, depending on the application. The proposed rulemaking will also accelerate the exploration of emerging alternatives, such as R-448A, R-449A, R-450A and XP10, etc.

Emerson Climate has been actively participating in meetings and discussions with the EPA and industry organizations and will continue to do so throughout the commenting process. It is essential that the move to low-GWP refrigerants continues to progress. But it is also important the rulemaking strikes a balance that accounts for the infrastructure changes and resources necessary to support the transition in an effective, commercially viable manner.

We will continue to work proactively on alternatives to make sure you have access to the products and services you’ll need to remain compliant with SNAP. In many cases viable substitutes are already approved and ready for application. We continue to work on developments that will not only meet this NOPR, but keep you compliant with foreseeable future rulings.

We welcome and encourage your participation and feedback throughout the commenting period. We’ll cover the proposed changes and discuss their implications in more detail in our Making Sense webinar on August 26. Click here to register.

For specific details of the proposed changes, review the Rule and Fact Sheet published by the EPA. Check back here for further updates as new information becomes available. We believe the final rule can be expected sometime in late November or early December.
