    • Water vapor is removed from a mixture of air, metabolic carbon dioxide (CO2), and water vapor prior to removing the CO2 from the mixture. The water vapor-containing mixture is passed through a membrane module which is operative to separate the water vapor from the air and CO2 mixture. The water vapor in the entering mixture will pass in one direction through the membrane in the module from an entry side of the membrane to an exit side of the membrane. The membrane divides the module into two chambers, one of which receives the water vapor-containing mixture, and the other of which receives CO2-free air from a CO2 adsorbant station. The water vapor-containing mixture is removed from a closed habitable environment such as a space station, a space suit, a submarine, or the like, and is moved through the membrane module where the water vapor is removed from the gas stream. The water vapor-free gas stream then flows through the CO2 adsorption station where the CO2 and any remaining water vapor are separated from the air in the mixture. The CO2-free air then flows back through the membrane module via the membrane module exit chamber where the air is rehumidified with the water vapor that has passed through the membrane. The rehumidified air stream is then returned to the dosed habitable environment where it can be used for breathing purposes.
    • 在从混合物中除去CO 2之前,从空气,代谢二氧化碳(CO 2)和水蒸气的混合物中除去水蒸气。 含水蒸汽的混合物通过膜组件,其可操作以将水蒸汽与空气和CO 2混合物分离。 进入混合物中的水蒸气将沿一个方向通过模块中的膜从膜的进入侧到膜的出口侧。 膜将模块分成两个室,其中一个容纳含有水蒸气的混合物,另一个室从二氧化碳吸附站接收无CO2的空气。 将含水蒸气的混合物从诸如空间站,太空服,潜艇等的封闭的可居住的环境中移除,并且通过膜模块移动,其中水蒸气从气流中移除。 然后,无水蒸气气流流过CO 2吸附站,其中CO 2和任何剩余的水蒸汽与混合物中的空气分离。 然后,无CO2的空气经由膜组件出口室通过膜组件流回,空气用已经通过膜的水蒸汽进行再湿化。 然后将再加湿的空气流返回到可用于呼吸目的的定量适应环境中。
