AHRI launches 'mildly flammible' research project

The Air Conditioning, Heating and Refgigeration Institute (AHRI) in the US has launched an investigation into the ignition of A2L or ‘mildly flammible’ refrigerants

The research project, entitled the Investigation of Energy Produced by Potential Ignition Sources in Residential Applications, was awarded to the University of Maryland’s Department of Fire Protection Engineering.

The project’s goal is to evaluate energy produced by potential ignition sources in residential applications relative to minimum ignition energy from a list of A2L refrigerants, and to investigate the likelihood of the presence of ignition sources and refrigerant ignition. The results could be used to expand the existing risk assessment studies of A2L refrigerants by providing further detail.
