Abstract

L'invention porte sur un climatiseur à sorption de traitement par lots, lequel climatiseur est apte à exécuter un mode de refroidissement, un mode de réchauffement et un mode de maintien de chaleur. Le traitement par lots est exécuté à l'aide d'un changement d'états de contact entre des récipients et des éléments de transfert de chaleur à l'aide du déplacement périodique d'au moins l'un des récipients, des éléments de transfert de chaleur et des saillies pour le transfert de la chaleur entre les éléments et les récipients. Le récipient de sorbat est disposé en une position inférieure à celle du récipient de sorbant.
