As a result of the Montreal Protocol and the EPA AIM Act, the demand for refrigerants with a low GWP has forced the HVAC&R industry to consider refrigerants that are flammable. Two standards that are used today include the 2022 editions of ANSI/ASHRAE 15, Safety Standard for Refrigeration Systems, and ANSI/UL 60335-2-40. This seminar reviews the changes to these standards as it relates to low GWP refrigerants in design, installation and service of residential AC and R systems.
