Abstract

Appareil solaire de refroidissement compact et transportable sans tube, sans pompe et sans soupape de détente, n'utilisant comme source d'alimentation que la chaleur solaire. Des membranes semi-perméables font office de paroi de cloisonnement entre un évaporateur (2) basse pression et un générateur (3) d'absorption de vapeur à pression normale, et de paroi de cloisonnement entre l'évaporateur (2) basse pression et un condenseur (4) à pression normale. Le solvant se trouvant dans l'évaporateur (2) absorbe la chaleur et la transforme en vapeur à solvant, laquelle passe à travers une membrane (31) semi-perméable pour être absorbée dans la solution, dans le générateur (3) d'asorption de vapeur et changé en solvant. Ledit solvant se transforme alors à nouveau en vapeur à solvant du fait de la chaleur sensible à la condensation se produisant à ce moment et de la chaleur solaire, et ensuite il pénètre dans le condenseur (4). La vapeur à solvant en contact avec une plaque (43) dégageant de la chaleur produit de la chaleur à l'extérieur et elle se transforme aussitôt en un solvant, lequel passe à travers une membrane (41) semi-perméable, le solvant revenant alors à nouveau à l'évaporateur (2). Les processus précités sont renouvelés, et l'évaporateur est refroidi en continu.
