Abstract: An air diffuser module for use as a part of an outlet, plenum, or register for conditioned air and to support, be supported by, or connected to another part of the outlet is provided. The module comprises a module frame and at least one trajectory vane pivotally mounted horizontally within the module frame with each trajectory vane having internal stand-off walls for stabilizing each trajectory vane and causing additional trajectory travel when in contact with an arching surface of the thermostatic bimetal. A thermostatic bimetal strip is secured within each trajectory vane for adjusting the angle of each trajectory vane relative to the module frame responding to the temperature of the supply conditioned air with an arched portion formed on the thermostatic bimetal strip. The module provides an energy saving air pattern by directing conditioned supply air to the proper elevation for mixing prior to the air entering an occupied zone and thereby reducing air temperature stratification.

Abstract: A module for use as a part of an outlet for conditioned air and to support, be supported by, or connected to another part of the outlet. The module comprises a module frame and at least one deflection damper pivotally mounted vertically within the module frame. At least one trajectory vane is pivotally mounted horizontally within the module frame. An adjusting mechanism is secured within each trajectory vane for adjusting the angle of each trajectory vane relative to the module frame responding to the temperature of the supply conditioned air.

Abstract: An outlet for conditioned air has a plurality of interconnected modules establishing its side walls which support a closed bottom and by which the outlet is connected to a mounting frame. Each module has a supporting frame consisting of upper and lower side members and end members, each a length of an extrusion providing an outer wall and an inwardly disposed wall. Means are provided to interconnect the frames to each other vertically or laterally in the same plane or at right angles in a manner providing air tight seals.
