Host John Sheff interviews, Peter Dee, Danfoss’ Sales & Services Director for Food Retail in North America, about refrigerant trends in food retail applications, such as using alternative refrigerants, particularly natural refrigerants like CO2. Further they detail on what new and existing technologies are available to support an efficient, cost-effective transition to natural refrigerants, and the impact of refrigerant regulations.

Host John Sheff, Danfoss’ Director of Public Affairs, has Dean Groff, Danfoss Food Retail Services Contractor Manager, back to discuss flammable refrigerants, their regulations, and how to safely handle them.
The search for refrigerants that perfectly balance environmental, economic and safety concerns is continuing. Unfortunately, this quest throws customers and end-users off balance. Planning is stressful when the future is subject to change. Fortunately, in recent years, technology has developed to the point that it is possible to build a long-lasting platform for low-GWP commercial
One of the barriers to the new refrigerants is the recognition of flammable refrigerants in building codes. Codes dictate so much about building construction and what mechanical equipment can be used. There are codes for fire protection, building construction, mechanical systems, and other aspects of buildings; all affect the HVACR system. A good article on
The recently released report from the UN’s Intergovernmental Panel on Climate Change (IPCC) made it clear that unless we achieve net-zero carbon emissions and reduce additional greenhouse gases over the next decade, we may be facing pronounced environmental changes, including weather extremes and severe weather events. Conversations at both the state and federal level are
Francis Dietz calls in to the show to discuss the importance of indoor air quality (IAQ), especially in a post-pandemic world. Their conversation centers around what IAQ is, how it can impact health and safety, some of the costs associated with upgrading HVAC systems to improve IAQ, and some of the challenges businesses and schools face in improving IAQ.
John speaks with Clay Nesler about building energy efficiency, especially how it ties to economic recovery and resilience in the face of the global COVID-19 pandemic. Their discussion includes some of the various efficiency standards throughout the world and different approaches to retrofitting existing buildings.
In this episode of the Envisioneering Exchange podcast, host John Sheff and guest Vic Marinich, the Global Marketing Director for Air Conditioning at Danfoss, take a look at the current landscape of refrigerants for air-conditioning applications (from R-22 to R-410A, to R-134a and beyond). Later in the podcast, they discuss the phasedowns of high-GWP refrigerants as well as the emergence of flammable and mildly flammable refrigerants.
Welcome to the debut episode of the Envisioneering Exchange podcast. In our first episode, host John Sheff, Danfoss’ Director of Public Affairs, and guest Dean Groff, Danfoss Food Retail Services Contractor Manager, discuss the current landscape of refrigerants and the impact of US and Canadian regulations (American Innovation in Manufacturing Act, SNAP, CARB, Climate Alliance).
A safe transition to low-GWP refrigerants in the US is made more complex by the Montreal Protocol, the original international treaty finalized in 1987 to phase down Ozone Depleting Substances, or ODS, which included HFC predecessors CFCs and HCFCs. The Kigali Amendment to the Montreal Protocol amended the international treaty in 2016 to reduce greenhouse
