The invention concerns a device for recycling air in an enclosed or quasi-enclosed space featuring independent operating energy, including a reservoir (12) containing a cryogenic material used for the production of the said operating energy. The device includes a main heat exchanger (10) operating at atmospheric pressure to exchange heat between the air to be regenerated (14) on the one hand and the cryogenic material on the other hand, the cryogenic material heated to its operating temperature in the production of energy allowing the carbon dioxide, contained in the air to be regenerated, to be cooled, so the carbon dioxide passes from its gaseous state to its solid state. This device can be used advantageously for the regeneration of air in a submarine, using the heat of the oxygen stored in its liquid state to be used as a combustible in the submarine's engines.
L'invention concerne un dispositif de régénération de l'air dans une enceinte fermée ou quasi-fermée disposant d'une énergie de fonctionnement autonome, comprenant un réservoir (12) contenant un matériau cryogénique utilisé pour la production de ladite énergie de fonctionnement. Le dispositif comprend un échangeur thermique principal (10) fonctionnant à la pression atmosphérique pour échanger de la chaleur entre l'air à régénérer (14) d'une part et le matériau cryogénique d'autre part, le réchauffement du matériau cryogénique jusqu'à sa température de fonctionnement dans la production d'énergie permettant le refroidissement du dioxyde de carbone contenu dans l'air à régénérer de façon à faire passer le dioxyde de carbone de l'état gazeux à l'état solide. Ce dispositif peut être utilisé avantageusement pour la régénération de l'air dans un sous-marin, en se servant du réchauffement de l'oxygène stocké sous forme liquide en vue de son utilisation comme comburant dans les moteurs du sous-marin.
