Essential Guidance for Designing Duct Systems Duct Systems Design Guide gives engineers and other design professionals the tools to design properly sized duct systems to minimize fan energy consumption, system-generated noise, and the installed cost of ductwork. The guide also discusses duct system materials and the impacts they have on design and system efficiency, as well as fan-duct system interaction and using the ASHRAE Duct Fitting Database (DFDB). This tool is the perfect reference for HVAC engineers and designers seeking to develop more energy-efficient, accurate, user-friendly, and cost-efficient HVAC systems. Nearly every facet of duct design is covered in detail in this guide including: * duct layout * fitting selection * system leakage * acoustics * equipment selection * and more!
