May 12, 2006: Duct Design Manual Available for Public Review
CHANTILLY, Va. - The Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) has announced that the fourth edition of the HVAC Systems – Duct Design manual is available for public review. The manual presents the basic methods and procedures required to design HVAC air distribution systems.
With the growing emphasis on energy conservation, designers must balance duct size with the space allocated and duct system pressure loss, says SMACNA. HVAC Systems – Duct Design provides these guidelines. It contains the basic engineering guidelines for the sizing of HVAC ductwork systems, and also related information in the areas of materials, methods of construction, economics of duct systems, duct system layout, pressure losses, fan selection, duct leakage, acoustic considerations, duct heat transfer, as well as testing, adjusting, and balancing.
