Abstract
A workstation ventilation system is provided for offices divided into workstations by modular furniture units, such as partition panels, or the like. The ventilation system includes air ducts attached to the modular furniture units in the configuration of the furniture units, and further includes a collection and distribution unit for receiving air from an overhead ventilation system and for communicating the air through the air ducts to individual workstations. Optimally, the air ducts can be retrofittably attached to the furniture units to facilitate installation. Also optimally, the air ducts include air diffusers at each workstation, which air diffusers include individually adjustable deflectors to direct the conditioned air from the air ducts into the workstation area as desired.
