May 9, 2005—A new standard from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) provides a comprehensive set of airside, piping, controls and equipment symbols related to HVAC&R systems, says the association.
ANSI/ASHRAE Standard 134-2005, Graphic Symbols for HVAC&R Systems, identifies graphic symbols by name, configuration and description. The symbols are intended for use in the preparation of manual drawings and those produced by computer aided drafting.
Having a standard symbol language for consulting engineers and contractors will minimize the effort and time to universally interpret drawings, Herman Behls, a member of the committee that wrote the standard, said. Also, as the use and understanding of standard symbols increases, the accuracy and efficiency with which engineering designs are translated into actual systems will improve.
The cost of ANSI/ASHRAE Standard 134-2005, Graphic Symbols for HVAC&R Systems, is $47 ($39 ASHRAE members). To order, contact ASHRAE Customer Service at 1-800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 404-321-5478, by mail at 1791 Tullie Circle NE, Atlanta, GA 30329, or visit the ASHRAE.org Bookstore online.
