International efforts to address climate change are putting pressure on the HVAC&R industry to limit use of HFC refrigerants that have relatively high global warming potential (GWP) and transition to equipment designed around low GWP alternatives. To meet this challenge without compromising energy performance, companies are evaluating the use of mildly flammable (A2L) refrigerants. The presentations discuss recent activities to modify product safety standards to facilitate A2L use, recent R&D advances on A2L refrigerants and A2L implications for unitary product designs. An update on the impact of F-gas regulations on heat pump refrigerant options in Europe is also provided.
