Environmental concerns have driven refrigerant changes since the 1980s. The Montreal Protocol (1987) affected chlorine-containing refrigerants, and the Kigali Amendment (2016) addressed global warming concerns by restricting the use of high–global warming potential (GWP) refrigerants. The options to replace R-410A have been reduced by these measures, and replacements are mostly...
