VISIT AHR BOOTH B1638 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!
