Dedicated Outdoor Air Equipment-On Demand
- 1.5 CE
Dedicated outdoor-air systems have become increasingly popular. While previous discussions covered design and control considerations for dedicated OA systems, this ENL will focus on the equipment used to condition the outdoor air. Join Trane application engineers as they discuss the various types of equipment used for dedicated OA conditioning, from packaged DX units to split DX systems to air handlers and water chillers. Topics include: advantages and drawbacks of common dedicated OA system configurations, neutral versus cold air, ASHRAE 90.1 requirements related to dedicated OA systems, packaged DX dedicated OA units, various airhandler configurations using air-to-air heat exchangers and desiccant wheels, chilled-water DOAS, and water-to-water heat pumps.
