摘要： Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes a shaft to be disposed within an air duct, to extend in a longitudinal direction, and to be in longitudinal compression. The air duct system also includes a plurality of ribs to be coupled to the shaft and to engage an inner surface of the air duct and a spring to be disposed within the air duct, the spring to be coupled to the shaft. The spring under stress being a contributing factor in both the shaft being in longitudinal compression and the air duct being in longitudinal tension.

摘要： Example air duct assemblies include a pliable air duct supported such that the duct is maintained in a generally expanded shape even when the duct is deflated. In some examples, a series of hangers suspend the duct from one or more cables, tracks or other type of overhead support. The hangers are spaced apart and distributed over the length of the duct, and each one contributes in pulling the duct taut in the duct's longitudinal direction.

摘要： Fabric drop-down diffusers are disclosed. An example drop-down diffuser includes a hoop to be supported adjacent an end of an air duct, and a first fabric sheet to hang downward from the hoop. The first fabric sheet to define a first wall of an air chamber adjacent the hoop on a side of the hoop opposite the air duct. The first fabric sheet to completely surround the air chamber along a circumferential path corresponding to the hoop. The hoop to be transverse to the air duct and positioned so that air delivered by the air duct is to pass through the hoop and into the air chamber. The drop-down diffuser also includes a second fabric sheet to be coupled to the first fabric sheet. The second fabric sheet to define a second wall of the air chamber.

摘要： Apparatus for tensioning pliable airducts while supporting internal HVAC components are disclosed. An airduct system includes an airduct having an elongate tubular wall of a pliable material. The airduct system further includes a frame disposable inside the tubular wall of the airduct, the frame including a hoop to support the tubular wall in a radial direction, the hoop to define an opening to provide passage of a flow of air along a length of the airduct. The airduct system also includes an HVAC component disposable within the tubular wall of the airduct, the HVAC component to be attached to and supported by the frame inside the airduct, the HVAC component to adjust a characteristic of the air.

摘要： Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.

摘要： An example air barrier system for a data center within a building is disclosed. The example air barrier system includes a pliable barrier material to partition an area above a top of row of computer cabinets in the data center and below an overhead surface of the building. The pliable barrier material is to reduce mixing of air between first and second aisles on opposites sides of the row of computer cabinets. The example air barrier system also includes a frame to support the pliable barrier material in position when in the area above the top of the row of computer cabinets. The frame is to be supported by the row of computer cabinets without support from the overhead surface.

摘要： Fabric drop-down diffusers are disclosed. An example drop-down diffuser includes an upper panel including an upper fabric sheet to be held in radial tension by an upper hoop. The upper panel defines a supply air inlet. The example drop-down diffuser further includes a lower panel to be underneath and spaced apart from the upper panel. The example drop-down diffuser also includes a circumferential fabric sheet to encircle the upper panel and the lower panel. The circumferential fabric sheet is to extend downward from the upper panel to the lower panel to define an air chamber bordered by the upper panel, the lower panel and the circumferential fabric sheet. The air chamber is connected in fluid communication with the supply air inlet.
