AHRI Releases Refrigerant Research Results

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) today released results of a project undertaken in cooperation with UL and the Firefighter Safety Research Institute (FSRI) in which refrigerants classified by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) as A2L (lower flammability) were tested and compared with A1 (no flame-spread) refrigerants in real-world situations. The effort was undertaken to develop training programs for firefighting personnel when responding to fires in occupancies with both new (A2L) and existing (A1) refrigerants.
