Name / Trade names: R-454B, often sold under the trade name Opteon™ XL41 (also known as Solstice 454B in some markets). AGATEX +3 Wikipedia +3 National Refrigerants Ltd +3 Purpose / Use: It’s designed as a replacement / successor to R-410A for new air conditioning and heat pump systems, particularly in ducted systems, mini-splits, chillers, etc., where direct expansion (DX) cycles are used. Schiessl Kälte +4 Opteon +4 פי.סי. חץ +4 Environmental benefit: R-454B has a much lower Global Warming Potential (GWP) than R-410A. Its GWP is ~ 466 (some sources list 467) vs. ~ 2088 for R-410A. That’s about a 78% reduction in GWP. AGATEX +4 Opteon +4 National Refrigerants Ltd +4 Flammability / Safety class: It is classified as a mildly flammable refrigerant — ASHRAE / ISO / EN safety class A2L (non-toxic, but low flammability) Schiessl Kälte +4 Opteon +4 Hudson Tech +4 Ease of adoption: It’s designed to be as close as possible in thermodynamic behavior to R-410A so that systems can be adapted / designed with minimal changes. In many cases, manufacturers view it as “drop-in alternative for new systems” with certain modifications (safety, component compatibility) considered.
