Dehumidified air then circulates in the second chamber of the installation, where it is remoistened by through the agents contained in this second chamber, having absorbed moisture during a cycle previous.
  • the installation also includes a four-way valve channels, to reverse the direction of the airflow compressed through the installation, so that this air tablet flows alternately from the first to the second chamber, and from the second to the first bedroom. Note that this recurrent inversion of direction of the flow of compressed air through the installation is a necessary condition for to be able to rewet the air produced. Thus, this installation seems only very little suitable for continuous air production, and does not allow under no circumstances to produce air breathable at a constant humidity level, during a important period.
  • this type of process involves a number of major disadvantages, including that of the complexity of the installation used, or still that of the inability to regulate the rate breathable air humidity produced.
  • Another disadvantage is the risk of desorption from the carbon dioxide, recovered during the passage of air in the column for remoistening.
