The Transition to Low-GWP (Flammable) Refrigerants in the Unitary Market

Available On-demand Until March 24, 2022

Duration:60 minutes


Recent federal and state hydrofluorocarbon (HFC) refrigerant legislation requires HVAC industry change to meet the growing call for environmental protection. This transition will have significant direct and indirect impacts on the Unitary sector (residential/commercial splits, packaged/rooftop units). Previous Unitary sector refrigerant transitions, like the move from R-22 to R-410A, were disruptive in execution but clear-cut from a regulatory standpoint. The next transition, likely to occur within a few years, will not be as straightforward. Multiple, mildly flammable, low-GWP refrigerants will be available as soon as building codes allow. This webinar shares the drivers behind the next transition, leading low-GWP refrigerant candidates, timing and possible consequences.
