    摘要: A device for infusing gas into a liquid comprises a housing and a tube having a width that is smaller than that of the housing and which is positioned within the housing such that the longitudinal axis of the tube is approximately parallel to that of the housing. The device further comprises potting compound interposed between an outside surface of the tube and an inside surface of the housing at both ends of the tube. Microporous hollow fibers extend from the potting compound at the first end of the tube and through the potting compound at the second end of the tube. Openings in the device allow for the introduction of gas and liquid into the device. Gas enters the device and into the microporous hollow fibers. Liquid enters the device and is exposed to the outer surfaces of the microporous hollow fibers. Gas passes from the microporous hollow fibers to the liquid and is dissolved into the liquid. Liquid infused with gas exits the device.

    摘要: Modular environmental control systems and methods for enclosed structures are described. In an embodiment, a first air chamber having one or more first openings receives air from an enclosed structure. The first air chamber includes one or more second openings configured to receive ambient air. The one or more second openings are selectively closable. A first duct delivers air from the enclosed structure to the first chamber via the one or more first openings in the first air chamber. A second air chamber receives air from the first air chamber and has one or more openings configured to deliver air to the enclosed structure. A plurality of air conditioning modules are removably mounted to a divider positioned between the first air chamber and second air chamber.
    Air from the first chamber is selectively received into the second chamber by passing through the air conditioning modules. A second duct is configured to deliver air from the one or more openings of the second chamber to the enclosed structure.
