Abstract:
A system for applying conditioned air to one or more spaces within a building having one or more surfaces including walls, floors, and ceilings, the system comprising:an underfloor plenum within the building to which conditioned air is to be applied;an air handling system for applying conditioned air to the underfloor plenum; andat least one modular terminal in a floor of the building, said modular terminal including a housing defining an interior space, at least one inlet air passageway formed in said housing and in fluid communication with said underfloor plenum, at least one outlet air passageway formed in said housing for applying conditioned air from the housing to a space within the building, and at least one device associated with the housing for controlling the flow of air through the housing; wherein said air handling system includes:a primary channel for mixing return air and conditioned air and applying the mixed air to the underfloor plenum;at least one fan within the primary channel for applying pressurized air to the plenum;a secondary cooling loop in fluid communication with the primary channel;at least one cooling coil within the secondary cooling loop;at least one fan within the secondary cooling loop for flowing air through the coil and applying it back to the primary channel; anda damper system for controlling the flow of air in and out of the secondary cooling loop, according to preselected criteria.
