Abstract

Conditionneur d'humidité (101) qui comprend des groupes de particules (20) et un boîtier de passage (19) dans lequel les groupes de particules (20) sont maintenus, les groupes de particules (20) comprenant, en tant que matériau principal, un matériau en gel polymère d'absorption d'humidité ayant la propriété : d'entrer dans un premier état dans lequel le matériau en gel polymère peut absorber (sorber) l'humidité et dans un second état dans lequel le matériau en gel polymère libère l'humidité ; de passer du premier état au second état lorsque les conditions environnantes sont satisfaites ; et de revenir au premier état lorsque les conditions environnantes sont insatisfaites. Le boîtier de passage (19) possède à la fois des entrées d'air (17) par lesquelles l'air est introduit de l'extérieur et des sorties d'air (18) par lesquelles est rejeté l'air qui a traversé les interstices entre les particules des groupes de particules (20). Les groupes de particules (20) comprennent un premier groupe de particules (21) ayant un premier diamètre et un second groupe de particules (22) ayant un second diamètre, qui est plus petit que le premier diamètre. Dans le boîtier de passage (19), le premier groupe de particules (21) a été disposé plus près des entrées d'air (17) que ne l'a été le second groupe de particules (22).
