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.
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.
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
In the previous post, we looked at the global path to a safe transition to low-GWP refrigerants, and the impact that actions by states like California are having on creating a patchwork of regulations and move us toward the use of highly flammable refrigerants. Here, I trace how the move impacts standards and codes, as
The global transition to low-GWP refrigerants is beginning in a disorderly manner in the United States — the world’s most mature HVAC market. In the absence of a federal framework, individual states are beginning to regulate HFCs. A handful of states are following SNAP Rules 20 and 21, the EPA regulations that were vacated by
Central to the life and operation of any community is its infrastructure. From its roads and other transportation platforms to its sewers and waste treatment facilities, and from its telecommunications and power generation and distribution networks to its building stock, a community’s infrastructure not only defines its quality of life in the moment, but also
For vessel owners interested in reducing fossil fuel consumption to meet IMO 2020 international marine emission standards, hybridization and electrification technologies complement or offer an effective alternative with many benefits. A basic definition of hybridization is any system with two or more sources of energy acting together to accomplish a task. In the automotive world,
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
The American building stock as a whole turns over at a rate of only one percent per year. Transformation that takes a century to complete is not transformation. That means the existing building stock needs to be retrofitted for efficiency and resilience—and those retrofits need to be deep. With the lack of federal leadership, states
