Abstract:
A pressurized air distribution network of conduits terminates in small, needle-like nozzles adapted to penetrate a wall, ceiling or layers of flooring, or other moisture-laden areas, such as trapped air space beneath cabinets, through an unobtrusive, easily repaired hole. Air is dispersed by positive-pressure nozzles within the area and collected by nozzles of negative pressure relative to the air pressure within the area. To maintain equal air distribution about a large area, air pressure at the several positive-pressure nozzles is maintained approximately the same by an air supply ring disposed about the relevant room. Spaced apart about the ring are several manifolds, each feeding air to a nozzle. The ring is maintained at near constant pressure, that is, with minimum pressure gradation about the ring, by attaching several air blowers around the ring. In lieu thereof, a central blower provides air to a duct which divides at least once into multiple conduits at at least one branch location.
