ASHRAE has published ANSI/ASHRAE Standard 147-2002, “Reducing Release of Halogenated Refrigerants from Refrigeration and Air-Conditioning Equipment and Systems.”

To meet the need to control releases of refrigerants into the atmosphere, American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) published ANSI/ASHRAE Standard 147-2002, “Reducing Release of Halogenated Refrigerants from Refrigeration and Air-Conditioning Equipment and Systems.”

The standard establishes practices and procedures that will reduce inadvertent release of chlorine-containing and other halogen-containing refrig-erants such as halogenated chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) refrigerants.
