Abstract

Le problème abordé par l'invention est d'augmenter la quantité de matériau adsorbant sans augmenter considérablement la taille d'un échangeur de chaleur. La solution de l'invention concerne un échangeur de chaleur de type à adsorption configuré de façon qu'un matériau adsorbant (200) soit chauffé/refroidi par le chauffage/refroidissement de tubes de transfert de chaleur (130), ce qui permet à de l'eau (l'adsorbat) d'être libérée du matériau adsorbant (200) ou adsorbée par celui-ci. Une pluralité des tubes de transfert de chaleur (130) est configurée avec des intervalles (L1) entre les tubes, et l'intervalle (L1) entre un tube de transfert de chaleur (130) et un autre tube de transfert de chaleur (130) est rempli du matériau adsorbant (200). Ainsi, la quantité de matériau adsorbant (200) dans l'échangeur de chaleur de type à adsorption est supérieure à celle lorsque le matériau adsorbant est supporté par des ailettes situées sur les tubes de transfert de chaleur (130).
