FIELD: transport.
SUBSTANCE: invention relates to machine building and can be used for keeping cryogenic fluid, and to method of vapour condensation. Proposed reservoir gas bottom part to keep cryogenic liquid and vapour chamber formed at reservoir top. It comprises condenser to condense formed vapour by direct heat exchange with cryogenic liquid fed into said reservoir. Condenser comprises contact adapter to bring vapour and fluid in contact. Said adapter comprises top and bottom parts. Top part is open toward vapour space to allow influx of formed vapour into adapter, while bottom part allows fluid medium to flow into reservoir bottom part. Reservoir comprises cryogenic fluid feed source, independent of reservoir, cryogenic fluid inlet orifice to feed it into said contact adapter top part and outlet orifice to remove cryogenic fluid from reservoir bottom. Method to condense vapour formed in said reservoir is realised with the help of condenser fitted inside reservoir. Condenser comprises contact adapter to bring vapour and fluid in contact. Method comprises overcooling of cryogenic fluid and feeding said fluid into contact adapter to bring fluid and vapour in contact. Formed vapour is condensed in said adapter due to direct heat exchange with fed cryogenic fluid.
EFFECT: simplified design.
