Emerson sees migration to lower-global warming potential (GWP) refrigerants as inevitable. Here are some challenges leading A1 alternatives may face, and how to potentially address them.

Heat of Compression

While new HFCs for R-404A offer a lower GWP, alternatives run significantly hotter in both low- and medium-temperature conditions. Compressor cooling will be needed in many low-temperature applications. This is potentially a big deal because some freezer applications can no longer run with non-liquid injected compressors. Full operating envelope capabilities are still possible with liquid injection, but this will likely require additional plumbing and power.

For low-pressure refrigerants, potential replacements for R-134A run at lower discharge temperatures, so there is less of a temperature concern. Our tests* have found the entire operating envelope for R-134A can be achieved with either 450A or 513A.

Capacity and Size

R-404A replacements typically deliver less capacity, especially in low-temperature applications, which will require larger compressors to match existing systems.

During our tests*, traditional HFC refrigerants like R-404A also had little or no temperature glide, so they didn’t affect system sizing. Emerging A1 replacements, however, have glide values of ~5 to ~8 °F. That potentially creates issues when calculating capacity that most of our industry hasn’t had to deal with in the past. Capacity at the midpoint in a medium-temperature system with R-404A, for example, isn’t much different from its dew point compressor rating. But an R-448A system would deliver 3 percent more capacity at the same conditions.

This is even more apparent in low-temperature systems. For example, if you’re sizing an R-448A system off dew point, you might expect capacity loss of 19.4 percent compared to R-404A. In reality, the system sees a drop of about 13.9 percent. While you’ll still have to increase the size of the compressor, using the midpoint can significantly affect your calculations.

In medium-temperature applications, the weighted Energy Efficiency Ratio (EER) of newer alternatives is similar to R-404A. In lower-temperature applications, there are trade-offs between efficiency and GWP. R-407A compares well with R-404A, but has a higher GWP than other alternatives. R-448A scores better on GWP, but requires more injection and power.

There’s little or no temperature glide in replacements for R-134A, but of the two main candidates, 513A meets or exceeds the capacity of R-134A, while 450A struggles in comparison.

Update on A2L/A3 Refrigerants

This presentation touched only briefly on A2L refrigerants, since they have yet to be listed as acceptable alternatives under the Environmental Protection Agency’s Significant New Alternatives Policy. However, Emerson continued testing functionality for A2Ls and the A3 R-290 throughout 2017. If you have any questions about these refrigerants, or want any evaluations done, please contact us to learn more about your options.

Many factors are lining up to help make the case for R-290, from demographics and sustainability to regulations. Watch the full video for more on overcoming common challenges, and to learn how one company, H&K International, successfully made the shift to focusing on R-290-based products.

Regardless of the EPA’s current or future actions, Emerson sees a significant market dynamic toward sustainability, lower Global Warming Potential (GWP) and higher efficiency — especially in the spaces where     R-290 is acceptable for use.

R-290 is a natural, hydrocarbon-based substance. In addition to its low GWP of 3 and Ozone Depletion Potential (ODP) of 0, Emerson’s compressor test labs* found that R-290 yields more than 20 percent better Energy Efficiency Ratio (EER) on average compared to R-404A and other HFCs. R-290 systems have been found by many to be highly reliable. Hydrocarbons can be used in multiple applications such as secondary systems, self-contained cases and condensing units.

The current charge limit for R-290 is only 150 grams, which can limit unit size and potentially create significant challenges for makers of stand-alone, medium-temperature reach-ins. Manufacturers of larger equipment are also understandably reluctant to take on the inefficiencies of supporting multiple refrigerants in their lineups.

Emerson is participating on the AHRI Flammable Refrigerants Research Subcommittee which will be investigating the impact of R-290 refrigerant charge limit increases. Increasing the charge limits could open up more applications in ice, commercial reach-ins, and potentially in some packaged solutions. The Subcommittee intends on submitting the results of its investigation for use in evaluating Codes and Standard revisions for IEC, UL, ASHRAE and others.

Most ultra-low-GWP refrigerants (A2L or A3 with a GWP less than 150) have some level of flammability, which may create some challenges. That said, R-290 systems tend to be reliable when proper protocols and procedures are followed. Integrated cases and packaged walk-in systems can use multiple 150g refrigeration systems in a single appliance. These have low- and medium-temperature applications that help to address today’s EPA and DOE compliance challenges, though DOE test procedures are still in development.

H&K International offers a compelling real-world example of the benefits R-290 offers to commercial foodservice. In the United States alone, the company projects its customers will save more than $769,000 in utility costs over the next three years, with additional savings each year R-290 equipment is in operation.

9628-E360_Webinar On Demand_Facebook_1200x630_wWebinarLogo

In our most recent E360 Webinar, I had the opportunity to present, alongside two of my Emerson colleagues, a discussion about what’s predicted on the 2018 regulatory horizon. As we enter the new year, the global HFC refrigerant phase-down continues in varying degrees in different regions around the globe. Here’s a summary of the current activity:

United States — Kigali amendment and the EPA

  • Although the U.S. has not yet ratified the Kigali amendment to the Montreal Protocol, the U.S. State Department issued a statement on Nov. 23 in Montreal that it had “initiated steps to ratify” the amendment.
  • Also in 2017, the U.S. Court of Appeals for the DC Circuit vacated Rule 20 and sent it back to the EPA for revision, stating in its ruling that the EPA had exceeded its authority under the Clean Air Act, Section 612 to require replacements of HFCs. Petitions for a rehearing were filed by several third parties, including leading refrigerant manufacturers and the Natural Resources Defense Council (NRDC).
  • Per EPA Rule 20, R-404A and R-507A are de-listed in new remote condensing units as of January 1, 2018.

Europe — F-Gas phase down

The year 2018 marks a significant drop in the F-Gas (i.e., HFCs) phase-down quota, from the previous 93% of the original baseline to 63%, where it currently resides. As a result, we are seeing an increase in HFC prices in Europe.

Canada — Kigali amendment and HFC ruling

Canada has ratified the guidelines set forth by the Kigali amendment. It has also issued a final HFC ruling that establishes a progressive phase-down schedule.

California Air Resources Board (CARB) — HFC phase-down effort

California has not only signaled its intent to adopt EPA Rules 20 and 21, its CARB initiative calls for even greater phase-down measures, making the target for future phase-downs as low as 150 GWP in certain applications.

Next, Amy Childress, vice president — marketing & planning, cargo solutions, and John Wallace, director of innovation, spoke on the topics of Food Safety Modernization Act (FSMA) and smart buildings.

FSMA — food safety and temperature management impacts

One of the ways food retailers can help prevent food-borne illnesses and comply with FSMA’s record-keeping requirements is by using automated temperature monitoring systems. These systems are easy to implement and provide proactive alerts to help prevent conditions that threaten food safety.

Smart buildings and the smart grid

While the concept of smart buildings with advanced building management and control system technologies is not new, the idea of equipping them with the tools that allow them to transact with services which are outside the building is. This ability to transact in real time when devices are connected can bring benefits not only to local electric utilities (which operate the grid) but also to building owners. There is increasing congressional interest in the potential benefits of smart buildings and their ability to not only respond to internal facility conditions but also consider outside factors such as real-time utility pricing.
