L'invention concerne un dispositif de déshumidification qui peut utiliser efficacement de l'air comprimé utilisé pour la reproduction d'adsorbant.　Le dispositif de déshumidification comprend : des récipients adsorbants 2A, 2B dans lesquels un adsorbant est contenu ; des vannes de commutation 3A à 3E connectées aux récipients adsorbants 2A, 2B ; un dispositif de commande 4 qui commute le processus de chaque récipient adsorbant entre un processus d'absorption et un processus de reproduction par commande des vannes de commutation 3A à 3E ; et une voie de libération d'air 9 qui libère l'air comprimé s'écoulant hors du récipient adsorbant dans le processus de reproduction. La voie de libération d'air 9 comprend un collecteur de chaleur 16 qui chauffe un fluide avec la chaleur de l'air comprimé s'écoulant hors du récipient d'adsorbant dans le processus de reproduction.
