ATLANTA - The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has published its 2004 refrigeration systems safety standard, which establishes procedures for operating equipment and systems to ensure the safety of building occupants and system technicians.
ANSI/ASHRAE 15-2004, "Safety Standard for Refrigeration Systems," includes clarifications to the application of safety relief valves for pressure vessels as well as the addition of flammable refrigerant restrictions in comfort cooling applications that were omitted from the 2001 standard. In addition, references utilized in the standard were updated.
