REFRIGERATION PROCESS AND DEVICE

Procede de refrigeration dans lequel: on chauffe jusqu'a evaporation un compose adsorbant sur lequel a ete adsorbe un fluide frigorigene; on condense les vapeurs ainsi produites de fluide frigorigene et on stocke le liquide ainsi produit; puis, on vaporise a nouveau ce liquide frigorigene et on adsorbe a nouveau sur le corps adsorbant les vapeurs ainsi detendues, de sorte que cette detente produise du froid; et dans lequel on opere au moyen de deux cuves (3, 4) contenant un compose adsorbant (7), ces deux cuves (3, 4) travaillant respectivement et alternativement en desorption et en adsorption, de facon a permettre une production continue de froid, caracterise en ce que on refroidit la cuve travaillant en adsorption. L'invention concerne egalement une telle installation. Application envisagee climatisation. Refrigeration process wherein: an adsorbing compound is heated until evaporation and on which a refrigerating fluid has been adsorbed; the vapours so produced from the refrigerating fluid are condensed and the liquid so produced is stored; then, this refrigerating liquid is again vaporized and the vapours thus expanded are again adsorbed on the adsorbing body, so that said expansion produces cold; and wherein this is effected by means of two tanks (3, 4) containing an adsorbing compound (7), these two tanks (3, 4) working respectively and alternatively in desorption and adsorption, so as to allow for a continuous production of cold, characterized in that the tank working in the adsorption mode is cooled. There is also disclosed such a plant. Application: air conditioning.
