ASHRAE F20-2009 (I-P)

Room air distribution systems are intended to provide thermal comfort and ventilation for space occupants and processes. Although air terminals (inlets and outlets), terminal units, local ducts, and rooms themselves may affect room air diffusion, this chapter addresses only air terminals and their direct effect on occupant comfort. This chapter is intended to present HVAC designers the fundamental characteristics of air distribution devices. For information on naturally ventilated spaces, see Chapter 16. For a discussion of various air distribution strategies, tools, and guidelines for design and application, see Chapter 56 in the 2007 ASHRAE HandbookHVAC Applications. Chapter 19 in the 2008 ASHRAE HandbookHVAC Systems and Equipment provides descriptions of the characteristics of various air terminals (inlets and outlets) and terminal units, as well as selection tools and guidelines. Other fundamental references include Bauman and Daly (2003), Chen and Glicksman (2003), Kirkpatrick and Elleson (1996), Rock and Zhu(2002), and Skistad et al. (2002).
