| 摘 要： | Long-duration manned submersible missions require advanced life support systems (LSS) that can regenerate air, water and food. This study presented two CO_2-capture methods used in LSS, CO_2 removal with diethanolamine (DEA) and cryo-freezing with liquid oxygen. Both processes were modeled and simulated with HYSYS simulator. The performance of the two types of module was compared, and the results showed that the latter could be advantageous over the former in specific power, facility scale, operation reliability and safety. Economic evaluation suggested the latter cost only half of the former. Cryo-capture module could be an alternative for underwater LSS because of its efficiency and compactness.
