  • Patent number: 4887641
    Abstract: A multiple blade damper for an air handling system of the type in which at least an adjacent pair of blades of the damper are operated in parallel, that is, in which each of such pair of blades is oscillated in the same direction as the other of the pair of blades which is adjacent to it. A generally L-shaped baffle is positioned in the duct in which the damper is located between the adjacent pair of damper blades in alignment with the overlapping edges of the damper blades in their closed positions, with a short leg of the baffle extending normally of the air flow path through the damper and a long leg extending along the air flow path, a major terminal portion of the long leg extending at a small acute angle, for example at 15.degree., with respect to the air flow path.

  • Patent number: 3963070
    Abstract: A multi-blade damper for an exhaust duct through which heated air flows after passage through heat exchange coils carrying a hot, liquid heat exchange medium which is subject to solidification if cooled too greatly, for example, sodium. When the heat exchange medium is very hot, air is forced through the duct by high volume fans and the damper blades are opened widely. When the source of heat to the heat exchange medium is shut down, however, the flow of the heat exchange medium and its temperature are greatly reduced. Even if the fans are shut off at this point, the natural draft of air through the duct may so cool the coils of the heat exchanger that the medium will freeze in the coils. Under these conditions, some of the damper blades are closed to majorly reduce the air flow. However, during the transition from hot operating conditions to stand-by conditions and during stand-by periods, the heat exchange medium must be kept hot enough to prevent solidification.
