The Department of Energy’s (DOE) 2014 ruling mandated 30–50 percent reductions in energy consumption on stand-alone commercial refrigeration equipment by March 27, 2017. For OEMs of stand-alone commercial refrigeration equipment, this placed them among the first to meet the task of compliance. But when you’re an OEM whose core principles are based on environmental sustainability — e.g., JSI Store Fixtures of Bangor, Maine — clearing these regulatory hurdles is just the cost of doing business. In fact, leadership at JSI seized this as an opportunity to revamp its refrigeration platform.

Eager to get out in front of the regulatory deadline, the OEM began working with its component suppliers in 2014 to begin the design, testing and DOE certification processes. At the same time, the Environmental Protection Agency (EPA) proposed the phase-out of commonly used hydrofluorocarbons (HFCs) in stand-alone commercial refrigeration equipment — a ruling that would become final in the summer of 2015 with a compliance date of 2019. Like OEMs, this presented a design dilemma for JSI: comply with each regulation separately or combine compliance efforts into a single design cycle.

By tapping Emerson’s regulatory stewardship and its expertise in compressor and electronic controls technology, JSI decided to tackle both DOE and EPA compliance requirements in the same design cycle. First, they worked with Emerson’s Refrigeration and Integrated Products group to develop an optimized, high-efficiency condensing unit that would serve as the basis of its wooden refrigeration fixture platforms.

The condensing unit features Emerson components, including: compressor, flow control and unit controller to facilitate tighter refrigeration control and an efficient assembly process into JSI’s refrigeration equipment. To make sure the new units met required energy objectives, JSI also utilized the DOE test validation and certification services of Emerson’s Design Services Network (DSN).

Completion of design, testing and certification

By the end of Q4 2016, JSI had completed the DOE certification process on 46 of its standard products, well ahead of the 2017 deadline. The effort required the commitment and dedication of the OEM’s strategic suppliers and partners, including an electronically commutated evaporator fan motor manufacturer, a third-party testing provider and Emerson’s DSN resources. In addition, JSI invested in an in-house testing facility where its units were ultimately rated for final certification.

To get out in front of the EPA’s HFC refrigerant ban in 2019, JSI opted to design its new stand-alone units to be “R-448A ready” — as the industry waits for the EPA to list new refrigerants R-448A/449A as acceptable for use through its Significant New Alternatives Policy (SNAP) program. JSI leadership made this decision based on a desire to align with the general direction the industry was heading and not impose difficult operating and servicing requirements on their customers.

The EPA’s phase-down of hydrofluorocarbon (HFC) refrigerants is underway. Over the next several years, these high-global warming potential (GWP) substances will no longer be permitted in a variety of commercial refrigeration equipment. As part of its Significant New Alternatives Policy (SNAP) program, the EPA has also listed new synthetic blends and natural refrigerants as suitable alternatives.

These new alternatives have different performance, servicing and handling requirements than their predecessors. To govern their safe use, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has designated safety classifications that denote varying degrees of toxicity and flammability:

  • A1: lower toxicity; no flame propagation
  • A2L: lower toxicity; lower flammability
  • A3: lower toxicity; higher flammability
  • B2L: higher toxicity, lower flammability

The performance (pressure and capacity) characteristics of common A1 HFCs are used as a baseline for the development of new lower-GWP alternatives. For example, R-448A/449A and R-449B are among the “R-404A like” (medium-pressure) options, while R-513A and R-450A are “HFC-134a like” (low-pressure) substitutes. These all have relatively lower GWPs than their HFC counterparts (350 to 1,300 GWP) and are EPA listed as acceptable for use in specific applications.

Several “future proof” options are currently undergoing the EPA’s SNAP approval process. To achieve very low-GWP levels below 150, these HFO blends all fall under the A2L (mildly flammable) classification. Among the medium-pressure alternatives include R-455A, R-454C and R-457A, while HFO-1234yf/ze and ARM-42 comprise the low-pressure options. Look for future SNAP ruling updates to verify their specific use parameters.

There are also a few very low-GWP, high-performance natural refrigerant alternatives that have been EPA listed as acceptable for use. Ammonia (refrigerant name R-717), propane (refrigerant name R-290) and carbon dioxide (CO2 or refrigerant name R-744) all occur naturally in the environment and have a long history of commercial use.

  • Ammonia — as a B2L, R-717 use requires careful adherence to safe use procedures. Its suitability in low-temperature applications has made it a mainstay in industrial, process cooling, cold storage and ice rink applications. Today, some supermarkets are trialing it in CO2 cascade systems to significantly reduce their carbon footprints.
  • Propane — R-290 is a high-capacity, energy-efficient refrigerant with superior performance characteristics. R-290 adoption has increased significantly as an alternative to HFCs R-404A and HFC-134a. Applications typically have a charge limit of 150 grams, making it well-suited for self-contained, reach-in display cases.
  • CO2 — Non-flammable and non-toxic, CO2 has proved a very effective alternative in both low- and medium-temperature applications, especially in regions with lower ambient temperatures. Its unique operating characteristics have led to the development of cascade, secondary and transcritical booster system architectures — all of which have been successfully deployed in commercial and industrial applications in both Europe and the U.S.

Today’s small-format retail and foodservice operators face difficult decisions about which refrigeration architectures — and refrigerants — will be the bases of their next generation of refrigeration platforms. Whether they’re motivated by global regulatory actions to reduce the use of hydrofluorocarbons (HFCs) with high global warming potential (GWP), or simply stating sustainability objectives to improve energy efficiencies and minimize their carbon footprints, operators have a variety of lower-GWP refrigerant options at their disposal.

Natural refrigerants carbon dioxide (CO2, or refrigerant name R-744) and propane (R-290) are currently the only true “future proof” options that hold the potential to take compliance and sustainability concerns out of the equation. But their unique characteristics also introduce new safety and servicing considerations with which operators must become familiar.

In our most recent E360 Webinar, my colleague Allen Wicher, director or refrigeration marketing, and I explored the many factors small-format operators must consider when selecting a natural refrigerant system. I kicked off the presentation by reviewing the long history of natural refrigerants in commercial refrigeration and discussed the market and regulatory forces that are now driving their broad global resurgence.

In particular, I explained how the global F-gas reduction strategy to protect the environment, in combination with voluntary efforts of private industry organizations, were driving the transition away from HFC refrigerants toward lower-GWP options like CO2 and R-290. At the same time, the trend for smaller retail formats in urban areas persists, while the millennial generation continues to shape the consumer desire for convenience and more importantly, fresh, natural and organic food offerings from local, sustainable sources.

Making this decision even more complicated is an increasingly wide variety of equipment and system architectures at play. For CO2 options, I explained how smaller-format systems were scaled down versions of larger-format retail refrigeration architectures. For example, CO2 cascade and transcritical booster architectures can be effectively scaled for use as smaller, centralized systems. And for even smaller convenience store or restaurant applications — such as walk-in freezers and coolers — OEMs are now manufacturing CO2 remote condensing units.

While higher first costs can be a barrier to entry for small-format CO2 refrigeration, I demonstrated how the total cost of ownership is reduced with improved energy efficiencies, performance and lower maintenance.

Allen provided an update on the active regulatory landscape, including:

  • Safety (ASHRAE/UL) and charge limit standards (UL 427) currently underway for flammable refrigerants classified as A3 (R-290) and A2L (synthetic blends)
  • Summary of EPA refrigerant listings (currently no A2Ls are listed as acceptable for use)
  • California Air Resource Board’s aggressive stance on HFC phase-down

Allen then talked about the architectures where R-290 is currently being utilized, including: stand-alone, integrated cases and micro-distributed systems. To learn more about the use of natural refrigerants in small-format retail, click here to view this webinar in its entirety.

Mobilizing the Industry to Address the Technician Shortage

With all the talk about the regulatory challenges facing the commercial refrigeration industry today, it’s sometimes easy to overlook the elephant in the room — namely, its growing shortage of qualified HVACR technicians. While we’ve all been justifiably focused on understanding system design changes to reduce energy consumption and new refrigerants to lower our carbon footprint, no one in our industry has stepped forward to lead the charge on solving the technician shortage in a holistic manner.

9222-E360-Outlook-Facebook-1200x630-MagGlass-14

At Emerson’s annual contractor roundtable, the lack of qualified technicians was cited as the number one challenge facing contracting business owners. I would argue that it is perhaps our industry’s most pressing issue.

There is no quick fix to this situation. Finding a solution will take months, if not years, and require the commitment of a dedicated organization to drive this effort forward. Through our E360 platform, Emerson is committing to lead this important initiative.

At our E360 Forum in Tucson, Ariz., we took our first steps toward defining the framework of this effort. The event assembled industry stakeholders and vocational school educators for a half-day, E360 Industry Challenge session to examine the current state of the HVACR technician profession. Areas of focus included:

  • Awareness — Do we understand what’s at stake and agree on the problem?
  • Recruitment — How can we attract individuals with aptitude?
  • Training — How can these individuals receive training, and what should those programs look like?
  • Certification — Which types of certification should be made available?
  • Retention — How can we keep individuals engaged throughout their careers?

In 2017, E360 will host a larger Forum focused solely on addressing the technician shortage. This multi-day event will feature an interdisciplinary team dedicated to understanding the problem, defining a working road map for meeting the challenge, and assigning specific actions to solve it.

In addition to industry stakeholders, we will seek insights from previously untapped resources. We will also seek the expertise of educators who have experience in developing curriculum and recruiting candidates. Our technical colleges, vocational schools and trade associations will all play key roles in shaping this piece of the puzzle. We may also benefit from government representatives and/or agencies who may be able to affect policy changes that can further our cause.

Certainly, the current regulatory climate is a dynamic situation that will continue to impact us for years to come, and our E360 platform will remain dedicated to helping you navigate this changing landscape. But without qualified technicians to service the next generation of refrigeration equipment, our industry will have an even bigger challenge.

If you want to contribute to this effort or have ideas that may help, please reach out to us at E360. Stay tuned for updates on this topic.
