Variable Air Volume Systems for Environmental Quality

Stay on top of the hottest topics in HVAC with this guide to economical design, construction, and operation of variable air volume (VAV) systems. It gives you proven methods of using VAV to improve air quality and prevent "sick-building" syndrome. The authors explain VAV operating principles, technology, and utilization. They show how computers help to design and simulate various conditions so you can implement the most ideal system. Sections on assessing conditions explain how to analyze ventilation, thermal comfort, indoor air quality, noise, building pressurization, outdoor air variation, duct static pressure, control stability, and the control scheme. Use of a process perspective throughout clarifies how VAV systems work and how to make them better. Detailed chapters encompass load estimation and calculation, architectural considerations, system selection, inspection, equipment protection, and air balancing and testing. Numerous examples help you avoid VAV design mistakes and installation errors, as well as overcome limitation. Featuring all necessary equations, this guide helps you achieve the best possible indoor air quality.
