Working Fluids and Refrigerants Sessions
Two of the sessions during the IEA Chicago Heat Pump Conference focused on reducing the global warming impact of refrigerants, specifically R-410A, through the use of alternatives with lower global warming potential (GWP). The papers presented explored various possibilities using thermodynamic calculations, system modeling, and experimentation. The adoption of R-32 by manufacturers for heat pumps was discussed, but there was recognition of the need for even lower-GWP fluids in the future.
