    • A system for sealing a building air duct in response to a chemical or biological attack to prevent the building HVAC system from delivering the chemical or biological agent throughout the building. The system can include an inflatable bladder for disposition within an air duct, a source of gas for expanding the bladder, an initiator for initiating the gas expansion, and a detector for detecting the agent. One bladder is formed of a resilient material suitable for extending into duct corners. Another bladder is larger than the duct to be sealed and is formed of a non-resilient material capable of inflating and bunching into duct corners. One source of gas is a gas canister while another source of gas is a chemical composition capable of reacting and forming the gas. One bladder includes a foaming agent which can expand and solidify within the bladder. One initiator utilizes an electronic signal to initiate the gas expansion. Another initiator includes use of an RF signal to initiate the gas expansion. One agent detector samples duct air while another detector includes a horizon detector for detecting agents in the air outside the building.
    • 一种用于响应于化学或生物攻击而密封建筑物空气管道的系统,以防止建筑物暖通空调系统将整个建筑物的化学或生物物质输送。 该系统可以包括用于配置在空气管道内的可膨胀气囊,用于膨胀气囊的气体源,用于引发气体膨胀的引发剂,以及用于检测试剂的检测器。 一个气囊由适于延伸到管道角的弹性材料形成。 另一个气囊大于要密封的管道,并且由能够充气和聚集成管道角的非弹性材料形成。 气体的一个来源是气体罐,而另一个气体来源是能够反应和形成气体的化学组成。 一个膀胱包括可在膀胱内膨胀和固化的发泡剂。 一个启动器利用电子信号来启动气体膨胀。 另一发起者包括使用RF信号来引发气体膨胀。 一个代理检测器对管道空气进行采样,而另一个检测器包括用于检测建筑物外的空气中的试剂的水平仪检测器。

    • A system for sealing a building air duct in response to a chemical or biological attack to prevent the building HVAC system from delivering the chemical or biological agent throughout the building (20). The system can include an inflatable bladder (102) for disposition within an air duct (100), a source of gas for expanding the bladder, an initiator for initiating the gas expansion, and a detector for detecting the agent. One bladder (102) is formed of a resilient material suitable for extending into duct corners (103). Another bladder is larger than the duct (100) to be sealed and is formed of a non-resilient material capable of inflating and bunching into duct corners (103). One source of gas is a gas canister while another source of gas is chemical composition capable of reacting and forming the gas. One bladder includes a foaming agent which can expand and solidify within the bladder.

    • A damper (10) includes an elastic bladder (16) which is attached to and surrounds a support element (32) mountable in a ventilation duct (12). The bladder (16) inflates when supplied with fluid to restrict the available air space within the duct (12), thus restricting airflow through the duct (12). The amount of restriction can be regulated by monitoring (40) the degree of inflation of the bladder (16) and by controlling the degree of inflation to provide the desired airflow restriction rate. The bladder may be inflated by supplying pressurized air to the interior of the bladder (16) through the support element (32) or by vaporizing a refrigerant in communication with the bladder. The damper may comprise a single bladder (16) extending longitudinally through the duct or a plurality of bladders (128) extending transversely across the duct (112).
    • 阻尼器(10)包括弹性囊(16),该弹性囊(16)附接到并围绕可安装在通风管道(12)中的支撑元件32。 气囊(16)在被供应流体时膨胀以限制管道(12)内的可用空气空间,从而限制通过管道(12)的气流。 可以通过监测(40)膀胱(16)的膨胀程度并通过控制膨胀程度来提供所需的气流限制率来调节限制的量。 通过将压缩空气通过支撑元件(32)供应到囊(16)的内部,或通过使与气囊连通的制冷剂蒸发而使气囊膨胀。 阻尼器可以包括纵向延伸通过管道的单个囊(16)或跨越管道(112)横向延伸的多个囊(128)。
