Method and apparatus for controlling the co2/02 concentrations of a space for example a cooling cell.

摘要

Method and apparatus of controlling the CO2/O2 concentrations of a gas mixture in a space<2,3,4> using successive adsorption and regeneration processes. At the beginning of the regeneration process at least a part of the gas mixture then being in contact with a adsorption material<8> is stored for use at the termination of the regeneration process in flushing the adsorption material. The stored gas mixture can also be used in maintaining an atmospheric pressure in said space.<2,3,4>
