ASHRAE 15-2007 Addenda a, b, c, d, e PDF

ASHRAE Standard 15-2007, Section 7.5.3, allows the use of Group A3 refrigerants where approved by the authority having jurisdiction (AHJ). Small portable cooling appliances and/or self-contained refrigeration systems are generally not regulated by the model codes that form the basis for most local regulation (see the 2006 International Mechanical Code, Section 106.2). Requiring specific local approvals from the AHJ for systems using small amounts of flammable refrigerant charge would be impractical, and inconsistent with national code practice. This addendum allows the use of such systems through an exception to Section 7.5.3.
