Marek Zgliczynski on behalf of the International Electrotechnical Commission — IEC)

“Nearly all countries in the world accept products according to IEC standards to ensure the safety of electromechanical equipment.”

“The current standard for any commercial refrigeration applications is basically a copy & paste from the standard applicable to domestic refrigeration.”

“The current standard for commercial refrigeration is a problem since we have clear limitations with cooling capacity with a 150gr charge limit for A3 refrigerants [hydrocarbons].”

“After 4 years of work of the working group revising the standard [IEC 603335–2–89], we’ll know this fall if the review to raise the limit to 500gr for A3 refrigerants goes through.”

“The international vote on the review of the standard is open now, and it will close in July 13. Probably over the next two weeks all nations will vote the current draft.”

“The review of this standard is key to implement Kigali. So I ask all of you to express your support via each national committee.”

“If we fail at this stage [to revise the standard] it will take another 3 years to create another proposal.”

“If the standard review goes through, we could see the new charge limit of hydrocarbons raised to 500gr in the US as from 2020, in a best-case scenario.”

Marek Zgliczynski, International Electrotechnical Commission

“It is our responsibility that safety standards are revised according to the best knowledge we have to use refrigerants safely. Make sure you are talking to your government to incentives a transition to low GWP available” — Avipsa Mahapatra, EIA

“SNAP Rule 20 is currently on hold, but SNAP Rule 21 is still in place, covering many applications and alternatives.”

“The EPA is also developing new regulation.”

“As of yesterday, 38 countries have already ratified the Kigali Amendment. The global movement towards phasing out HFCs is underway.”

“There are several initiatives across the US in support of climate friendly legislation, so It’s not all bad news.”

“Just because something is flammable does not make it unsafe. To me, no refrigerant is completely safe. Even with water, if you drink too much of it, you can drown.”

“We believe may of the standards applicable in this industry are obsolete and need reviewing.”

“You have an opportunity to join your national committee to actively engage [in the standards review].”

“If you are not able to follow, make sure to identify members that can represent your position.”

#ATMOAmerica’s Market Trends session had #Hillphoenix #CarnotRefrigeration #Emerson and #Embraco on the stage with global market trends presentation from #shecco

Market Trends Session

“We now start seeing a development [in technologies] in many places around the globe. However we are still in early days. Concretely in the USA, what we’ve seen is a relatively low starting number but a relatively high growth in the last years, especially since 2013. This is especially driven by manufactures in the local market” — Alvaro de Oña, shecco

Alvaro de Oña, shecco

“One important question to see what’s going to happen with NatRefs is the current standard debates, as of how much charge will be able to use in the future.”

“Moving to Industrial Refrigeration, we’re seeing a lot of development in this market. Now we’re seeing a variety of options, from NH3 low charge, CO2 TC and NH2/CO2.”

“The return on investment for the even user is becoming more and more important, and the competition is growing, which is also helping to push the prices more and more down for those (NatRef) solutions.”

“65% of all applications in the HVACR are HVAC, so 65% of applications are basically in their infancy of their development, so there we expect strong development in the coming years.”

“There’s a lot of interest for low charge ammonia, we almost can’t handle the requests — it’s really exciting the market interest” — Scott Martin, Hillphoenix

Scott Martin, Hillphoenix

“We have 6 large CO2 TC systems in the US already, some of them already existing, some in progress. One of our biggest sector for us is data centers” — Marc-André Lesmerises, Carnot Refrigeration

Marc-André Lesmerises, Carnot Refrigeration

“The digital shoppers are changing the market. Convenience is all about making it fast and making it easy. End users also expect us to invest, as it’s also a lot of investment on their side. We need to invest in better systems” — André Patenaude, Emerson

André Patenaude, Emerson

“You can see that R290 are still best in performance, compared to the other A2L refrigerants… [Charge limits] With most applications on smaller formats we’re covered, but larger applications are a bit tougher” — John Prall, Embraco

John Prall, Embraco


“For us in #California we have a trajectory of not waiting for the Federal legislators to take leadership in environmental issues. The development Electric cars is an example of that” — California State Senator Ricardo Lara

California State Senator Ricardo Lara

“Super pollutants are much more harmful to the #environment and to the detriment of our health. We are linking climate legislation to our health. Reducing the use of #HFCs is part of our efforts to reduce #superpollutants emissions” — Ricardo Lara

“Our cooling act allows us to use our market signals and our cap and trade system to create an incentive program to switch into low GWP technology for refrigeration, and move away from HFCs.”

”We actually believe in science here in #California! Our long-term goal is to reach our #climate goals. Our short-term goal is to reduce emissions from super pollutants” — Senator Ricardo Lara

“We are the 5th largest economy in the World. Our cap and trade system allows us to send a signal to the market. No matter what happens at the Federal level, California is not going to go back on environmental legislation.”

“We want to help you out in your transition to low GWP solutions.”

“We have a sense of urgency because these technologies [refrigeration] tend to stay for long time.”

“We’ve done incentive programs before in California successfully, for example to incentivize clean and more efficient trucks, investing over a billion dollars. Now we continue to expand the framework to HFCs.”

“We understand our global responsibility to contribute to leave a planet in better shape than what we received.”

“If you are interested in supporting the legislation we can help you draft a letter of support. It makes a world of a difference, especially with our more moderate and Republican representatives. We would greatly appreciate your letters of support.”

“In California we tripled our number of jobs in the last few years thanks to our environmental policies compared to traditional industries.”

“We find it’s much easier to engage business in an incentive program rather than creating new taxes, in an already high tax State such as California.”

“If the conversation stays only in this room it goes nowhere.”

[About incentives] “We want to make sure we give you the certainty that we are going to keep investing in these technologies over several years.”

Congratulations to Senator Ricardo Lara - an inspirational environmental leader and politician on his Accelerate America Person of the Year Award! We hope that other leaders will follow your footsteps Senator! @RicardoLara4CA

“Hydrocarbons, carbon dioxide and ammonia have become mainstream options” — Pega Hrnjak, CTS & University of Illinois at Urbana-Champaign

Pega Hrnjak, CTS & University of Illinois at Urbana-Champaign

Hydrocarbons: “Interest in hydrocarbons is increasing because of the low cost of the technology.

“Hydrocarbons are easy to work with, and a great replacement for R22.”

CO2: “We have known for over 10 years that, below 25degC, CO2 is more efficient than R134a in automotive applications.”

“CO2 has become a mainstream refrigerant in supermarket applications, and is now being used in a wider range of climate zones.”

“As electric cars become more popular, the advantages of CO2 heat pumps become important.”

“With CO2 heat pumps, you can extend the winter driving range of an electric vehicle by 30%”

“In the research field, activity in CO2 heat pumps for mobile air conditioning is like a beehive.”

“We can make CO2 systems efficient and low cost. We have already demonstrated that.”

Ammonia: “Ammonia charge should be reduced, and the industry has made a very strong start.”

“Ammonia is an excellent refrigerant for chillers, and the industry should focus more on HVAC.”

“Today we have built a 10TR ammonia chiller with less than 1 lb of ammonia.”

“Ammonia allows a very low charge in heat exchangers due to its favorable thermophysical properties.”

“There is a race to build low, lower and ultra low-charge ammonia systems.”

System Evaluations: “We are working on proving the performance of low-charge ammonia packages through lab testing.”

“CTS have 100,000 sq ft of lab space where are are currently testing a variety of low-charge ammonia systems.”

“Even our first results (of low-charge ammonia testing) show very good numbers in capacity and efficiency.”

Ammonia Chillers: “The market for HVAC is huge, compared to industrial refrigeration, and growing at 5–10% per year.”

“In 2017 there was a $400 million market for air cooled chillers in the US.”

Good morning from Long Beach! #ATMOAmerica has officially started! Follow our live coverage here on Twitter and on Medium


ATMO Events App

The 7th Annual ATMOsphere America will be returning to California once more to shape the future of the industry!

ATMOsphere America 2018 will be held at the Hyatt Regency Long Beach, CA on June 12–14 where key experts, policy makers and end users will gather to learn about the very latest developments in the industry.

We are returning to California at a time when environmental policy at federal level remains uncertain: this makes California’s place as the leader in progressive policy more important than ever before.

Our 2018 conference highlights include:

  • Keynote interview with Senator Ricardo Lara
  • Technology trends by keynote speaker Prof. Pega Hrnjak
  • Networking, technomericals and expo hall tours
  • The latest news on California and federal policy trends
  • Updates on incentive programs to accelerate natural refrigerant adoption
  • Presentation of the “ World Guide to Low Charge Ammonia”
  • Insight into the growing trend for CO2 transcritical in larger applications
  • Latest news on the revision of hydrocarbon charge limits


California Senator Ricardo Lara (D-Bell Gardens), a leading advocate for reducing harmful emissions of hydrofluorocarbons (HFCs) in the atmosphere, will be the keynote speaker on June 12 at 11:30 am at the ATMOsphere America 2018 conference.

ATMOsphere America, now in its seventh year, will be held June 12–14 at the Hyatt Regency Long Beach. Hosted by Belgium-based shecco, the conference focuses on natural refrigerant replacements for HFCs, which are potent greenhouse gases contributing to global warming, and for ozone-depleting gases that are being phased out in the U.S. and globally.

Last November, Lara, author of the Super Pollutant Reduction Act (Senate Bill 1383), announced the California Cooling Act (CCA) to combat what he termed the “silent assassin” of HFCs in refrigerators and air conditioners “that threaten our global climate.”

The CCA establishes financial incentives for businesses such as supermarkets and cold-storage warehouses that are switching to climate-friendly refrigeration from HFCs.

Lara will discuss the CCA in his keynote remarks; he and his staff are seeking feedback on the CCA from stakeholders attending the event. He also encourages end users of refrigeration and air conditioning equipment to send letters of support (preferably on official letterhead) to and attend hearings on the bill at the legislature.
