Supply air outlets, terminal units, chilled beams, fan-coil units, and air curtain units introduce air into a conditioned space to obtain a desired indoor atmospheric environment. Return and exhaust air are removed from a space through return and exhaust inlets (inlet and outlet are defined relative to the duct system and not the room). This chapter describes this equipment, details its proper use, and is intended to help HVAC designers select room air distribution equipment applicable to the air distribution methods outlined in Chapter 57 of the 2015 ASHRAE Handbook—HVAC Applications.
