Title (EN) BALANCED ADSORBENT REFRIGERATOR
(FR) REFRIGERATEUR A ADSORBANT COMPENSE
Abstract:
(EN) A heat transfer apparatus (2) that uses an adsorbent material to generate a cooling effect. The heat transfer apparatus (2) includes a first vessel (4) containing adsorbent material (10) and a second vessel (6) interconnected to the first (4). A working substance is contained within the two interconnected vessels (4, 6). The adsorbent material (10) and working substance (26, 28) are sized such that the working substance is completely adsorbed in both liquid and solid states (26, 28) by the adsorbent material (10) from the second vessel (6) into the first (4), cooling the second vessel (6) and heating the first (4). Complete adsorption includes adsorption of the working substance by vaporization when the working substance is in a liquid phase (26) and adsorption by sublimation when the working substance is in a solid phase (28). The second vessel (6) contains a compressible foam which accommodates the expansion of the working substance when it changes phase from a liquid to a solid and prevents the second vessel (6) from breaking.
(FR) La présente invention concerne un appareil de transfert de chaleur (2) utilisant un matériau adsorbant pour produire un effet de réfrigération. Cet appareil de transfert de chaleur (2) comporte une première enceinte (4) renfermant un matériau adsorbant et une seconde enceinte (6) interconnectée à la première (4). Une substance de travail est confinée à l'intérieur des deux enceintes interconnectées (4, 6). Le matériau adsorbant (10) et la substance de travail (26, 28) sont dimensionnés de façon que la substance de travail soit totalement adsorbée, aussi bien à l'état liquide qu'à l'état solide (26, 28), par le matériau adsorbant (10) vers la première enceinte (4) à partir de la seconde enceinte (6), ce qui refroidit la seconde enceinte (6) et réchauffe la première (4). L'adsorption complète comprend une adsorption de la substance de travail par vaporisation, pour la phase liquide (26) de ladite substance, et d'une adsorption par sublimation pour la phase solide (28) de ladite substance. La seconde enceinte (6) contient une mousse compressible qui s'adapte à la dilatation de la substance de travail lorsqu'elle passe de la phase liquide à la phase solide, et prévient la rupture de cette enceinte (6).
