Title (EN) INFLATED FLEXIBLE SOLAR COLLECTORS
(FR) COLLECTEURS SOLAIRES FLEXIBLES GONFLABLES
Abstract:
(EN) An inflatable collector for solar energy is provided in which superposed layers of plastic sheet material (18, 19) a heat sealed to one another to provide a pair of layers providing an absorber unit in which the upper layer (19) is pigmented to absorb solar radiation and the pair of layers are sealed to one another in a pattern providing a continuous elongated path. Fluid is supplied to one end of this elongated path and at least one transparent layer (25) is provided overlying the pair of layers, to provide a return space (21) above the pair of layers, and valve means (22) are provided to interconnect the end of the elongated path remote from the fluid supply end with the return space so that fluid heated in the elongated path is further heated in the return space before being withdrawn from the collector.
(FR) Collecteur gonflable d"energie solaire dans lequel des couches superposees de feuilles de matiere plastique (18, 19) sont scellees a chaud les unes aux autres pour former une paire de couches constituant une unite d"absorption dans laquelle la couche superieure (19) est pigmentee pour absorber la radiation solaire, les couches etant scellees l"une a l"autre de sorte qu"elles forment un passage allonge continu. L"alimentation en fluide s"effectue par une extremite de ce passage allonge et au moins une couche transparente (25) repose par dessus la paire de couches, pour assurer un espace de retour (21) au-dessus de la paire de couches, et des valves (22) sont prevues pour relier l"extremite du passage allonge se trouvant eloignee de l"extremite d"alimentation en fluide avec l"espace de retour de sorte que le fluide chauffe dans le passage allonge est encore chauffe dans l"espace de retour avant d"etre extrait du collecteur.
