Climate Pros Inc. Joins the North American Sustainable Refrigeration Council as a Platinum Member

Glendale Heights, IL Climate Pros has joined the North American Sustainable Refrigeration Council (NASRC), a nonprofit taking action to address the hurdles of natural refrigerants in supermarket applications. Climate Pros is a contracting group specializing in commercial refrigeration, among many other things, who has actively prepared their technicians to work with natural refrigerants. Their training center in Chicago, Climate Pros University, is being remodeled to include a CO2 rack System trainer along with a Howe CO2 Ice Flaker and some CO2 coils for supermarket refrigeration.

“Climate Pros is committed to pursuing environmentally friendly solutions with natural refrigerants to help reduce our customers carbon footprint and do our part to protect the climate for our future,” says Todd Ernest, Founder and CEO of Climate Pros. “We are excited to be joining the NASRC and look forward to working together to promote a more sustainable future.”

Natural refrigerants, including carbon dioxide, ammonia, and hydrocarbons, are considered “climate-friendly” alternatives to traditional fluorocarbon refrigerants, which have been identified as the fastest growing source of greenhouse gas emissions globally. Natural refrigerant technology also offers improved energy efficiency and often can save end-users money in the long run.

However, there are several unique challenges that are slowing the widespread adoption of natural refrigerants in the commercial sector, including availability of contractors and service technicians who are trained to service natural refrigerant-based systems and equipment. NASRC is spearheading efforts to overcome these barriers and ultimately create a more sustainable future for supermarket refrigeration. Climate Pros is sure to be an outstanding addition to their network of industry stakeholders.

“We are excited to welcome Climate Pros to our community,” says Danielle Wright, Executive Director of NASRC. “To position themselves as experts in this rapidly growing field, they need to have a seat at the table. They have made a choice to invest and will be at the forefront of this industry.”  

NASRC and Climate Pros will work together on trainings, webinars, and other resources to benefit the supermarket community. In addition to service contractors, NASRC membership is composed of systems manufacturers, component manufacturers, consultants, engineering firms, trade associations, nonprofits, refrigerant distributors, and end-users. NASRC end-user membership encompasses nearly 14,000 supermarket locations who will benefit from Climate Pros and other NASRC members who are committed to overcoming the barriers of natural refrigerants.

ACHR theNEWS Covers NASRC Boise, Idaho Workshop

In May of 2018, NASRC held a natural refrigerants workshop in Boise, Idaho. The event was a great success with attendance from about 60 commercial refrigeration stakeholders, including contractors, end-users, manufacturers, utilities, universities, nonprofits, and engineering firms.

ACHR theNEWs published a great article summarizing the workshop:

 

"The North American Sustainable Refrigeration Council (NASRC) sought to provide some of that guidance in a workshop it recently offered. The speakers covered everything from current trends affecting the refrigeration industry to the various refrigerant options available for refrigeration systems. The lively interactive format prompted a lot of conversation — and debate — amongst attendees and offered greater insight into some of the complex issues that are associated with alternative refrigerants."

 

Nearly 14,000 US Supermarket Locations are NASRC members

The North America Sustainable Refrigeration Council (NASRC) is excited to announce that our  end-user membership now encompasses nearly 14,000 supermarkets. 

“The growth of this organization has been amazing,” says Keilly Witman, owner of KW Refrigerant Management Strategy and former head of the EPA’s GreenChill Partnership. “Supermarket end-users are excited, because the NASRC gets things done. After years of all talk and no action about the hurdles that stand in the way of natural refrigerants in this industry, we finally have an organization that flips it around - it’s all about action.”

Most of the NASRC’s efforts focus on overcoming hurdles in three areas: service contractors and technicians, cost, and codes and standards.

The main programs that address hurdles related to service contractors and technicians focus on matching end-users with trained, experienced service contractors, ensuring clear communication between end-users and contractors who are working on their first all-natural refrigerant store, and collaborating with traditional service technician training organizations to ensure that technicians have the training they need to successfully install and manage an all-natural store. 

The NASRC’s Natural Refrigerants Service Network, for instance, is an online tool that allows refrigeration service contractors to provide information about their natural refrigerant experience, along with the areas where they do business. End-users can join the online network and mine that data by geographic location and the natural refrigerant they are looking to use.

“The NASRC has just begun to make the most out of this tool; the ideas are endless,” says Bryan Beitler of Source Refrigeration. “Just the webinar the NASRC held for service technicians explaining the new requirements of the Section 608 amendments made it worthwhile to participate.”

The NASRC’s Return on Investment Progress Group is working to overcome the causes that tend to cause natural refrigerants to cost more than traditional centralized DX systems.

“There are big cost hurdles, like economies of scale, and there are smaller cost hurdles, like the lack of distributors that carry refrigerant-grade CO2,” says Mike Ellinger of Whole Foods Market. “The distributor problem sounds like its a small thing, but it costs money, and those costs build up over time, if you don’t have a solution for it.” 

In response, the NASRC has begun cooperating with HARDI, the trade association for HVACR distributors, to bring traditional distributors into the natural refrigerant supply chain. According to NASRC Executive Director, Danielle Wright, the NASRC and HARDI will work to find a distributor in any area of the country where an end user wants to open a natural refrigerant store. 

The codes and standards hurdle may be the toughest nut to crack, says Wright. “The organizations that write standards for supermarket refrigeration may not be aware of how urgent it is to get standards in place.” She cites the fact that California plans to require supermarkets to use refrigerants with a GWP less than 150 in just a few years.

“We are eager to work with ASHRAE and UL and discuss how to get these standards done, but they have few people on their committees who come from the refrigeration world, much less from the natural refrigerant world.”

“Is it any wonder that supermarket end-users are flocking to this organization,” says Witman, “given its track record in under three years of going to bat for supermarkets?” 

“We don’t really have to recruit supermarket end-users,” reports Wright. “They come to us, because they’ve heard about the progress we’ve already made in all of the areas that have prevented them from moving forward with naturals in the past. No problem is too small, or too big, for us to tackle.”

IEC Releases Draft Proposal for Increased Charge Limit for Flammable Refrigerants

Last month, the International Electrotechnical Commission (IEC) released their draft proposal to raise the maximum charge size for flammable refrigerants in commercial self-contained cases from 150 grams to 500 grams. This marks another significant step forward for the NASRC's work to change standards to increase the maximum charge limit for R290 use in self-contained equipment, one of the goals of the Codes & Standards progress group.

Why Does a Higher Charge Limit Matter?

According to Marek Zgliczynski, Chair of the IEC subcommittee responsible for developing the proposal, this standard, known as IEC60335-2-89, "is the basis for all regional and national product standards for household or similar commercial-type applications.” The proposed change will "increase the maximum allowable charge of flammable refrigerants in [commercial self-contained display cases], while maintaining the same safety level of the present standard with 150 grams," explains Zgliczynski.

The current charge limit of 150 grams is severely limiting the use of propane self-contained systems in the US. While 150 grams of propane is adequate for small-to-medium-sized display cases, the larger display cases that are prevalent in this country need more propane for cost-effective operation

The main concerns about higher propane charge sizes relate to safety, as is to be expected with an A3 refrigerant. The specific requirements in the IEC’s proposal ensure that cases with 500 grams of propane are as safe as those with 150 grams. These requirements include the following:

  • The refrigerant circuit must be hermetically sealed and mechanically protected;
  • Construction cannot cause excessive vibrations of circuit piping;
  • Airflow is required to avoid flammable concentration beyond the boundary of appliance, certified with a special leak test; and
  • Appliance must be installed in a room with a floor area not less than the marked minimum room area.

 What’s Next? 

The proposal has to pass two stages of voting, the first of which will close mid-July. The IEC is accepting comments from stakeholders at http://www.iec.ch/comment/ until that time. The NASRC will provide instructions to members on how to submit comments and template language that members may use to express support for the IEC proposal.

If the draft proposal receives a two-thirds majority in the first vote, it will move to the second and final stage of voting. If the proposal passes the final stage, a new edition of IEC60335-2-89 will be published in early 2019.

Zgliczynski noted that, "this new standard will allow for systems manufacturers to comply with present and future regulations phasing out high-GWP refrigerants globally in this specific market segment."

As state and federal governments ban or phase down high-GWP HFC and HFO-blend refrigerants, commercial refrigerant end-users will need access to technologies that use refrigerants with GWPs below 150. Propane self-contained systems show great potential to meet much of that need. The main hurdle preventing the widespread use of this technology in the US is the slow pace of ASHRAE and UL in revising their standards. The IEC proposal, if passed, is the stimulus that the US standards organizations need to get them moving in the right direction. To encourage ASHRAE and UL to work with the NASRC to speed up their timelines, sign the NASRC petition for faster revision of codes and standards.

NASRC Call to Action 

The NASRC is calling on industry stakeholders to contribute to this initiative with the following activities:
