Refrigerants
Refrigerants are common sources of hydrofluorocarbons. The refrigerant
industry uses a common naming system (ASHRAE 34) to describe both single-component
and blends. The chart below will help users identify the hydrofluorocarbon
and perfluorocarbon components and facilitate inventory reporting.
Pick refrigerant by refrigerant number.
