Optimizing the Flammability and Performance of Next Generation Low-GWP R-410A Replacements (OR-16-C015)

Flammability testing studies were conducted to support a methodology to optimize GWP to flammability for blends of R32, R1234yf and R125. Performance modeling studies were conducted to guide the best design of experiments for the flammability testing that optimize performance. Minimum ignition energy and burning velocity characteristics were determined for various blends of R32, R1234yf and R125 to determine flammability characteristics. This paper will discuss the results of these studies.
