In an effort to standardize symbols used by mechanical engineers on building drawings, the American Society of Heating Refrigerating and Air-Conditioning Engineers has issued a new symbol language for HVAC equipment.
ANSI-ASHRAE Standard 134-2995, Graphic Symbols for HVAC& R Systems identifies graphic symbols by name, configuration and description. The symbols are intended for manual and CAD drawings.
“Having a standard symbol language for consulting engineers and contractors will minimize the effort and time to universally interpret drawings,” said Herman Behls, a member of the committee that wrote the standard. He also suggested that a standard symbol system will increase the accuracy and efficiency of engineering designs.
