Podcast: A2L Refrigerants & Their Significance to the HVACR Industry

Sept. 28, 2023

Named for their ASHRAE safety classification, A2L refrigerants are characterized by mild flammability, low toxicity, and low global warming potential (GWP). They include hydrofluoroolefins (HFOs) and HFO blends. A2L refrigerants offer similar operating characteristics to legacy refrigerants, a safer profile than ammonia and hydrocarbon refrigerants, and are more energy efficient than R-410A and transcritical CO₂ systems.

As the world confronts the challenge of climate change, A2Ls have emerged as a replacement for older, high-impact refrigerants like HFCs and HCFCs in air conditioning and commercial refrigeration systems. A2Ls are essential for helping businesses meet the global objectives outlined in the Montreal Protocol and the Kigali Amendment, regional regulations like the U.S. AIM Act and Canada’s ODSHAR, as well as for achieving the objectives of the EU Green Deal.

During this podcast, Chemours will cover A2L refrigerants for AC, food retail and cold storage applications, recent adoptions by key OEMs for HVAC, and the benefit of A2L refrigerants to the industry.
