Abstract
(EN)
An Ocean Thermal Energy Conversion (OTEC) system having a turbine with an upstream side and a downstream side. Warm water under a partial vacuum is converted into a vapor, the vapor being supplied to the upstream side of the turbine at a pressure controlled by the temperature of the warm water. A condenser is situated on the downstream side of the turbine to cause the vapor, after passing through the turbine, to undergo a phase change back to a liquid, which can be used as potable water. The condenser is coupled to a source of a cooling liquid, and the pressure of the vapor on the downstream side of the turbine is determined by the temperature of the cooling liquid. A flexible floating solar collector supplies the warm liquid to the upstream side at a temperature higher than normal ambient temperature.

La présente invention concerne un système de conversion d'énergie thermique océanique comprenant une turbine avec un côté amont et un côté aval. De l'eau chaude sous un vide partiel est convertie en une vapeur, la vapeur étant fournie au côté amont de la turbine à une pression contrôlée par la température de l'eau chaude. Un condenseur est situé sur le côté aval de la turbine pour soumettre la vapeur, après sa traversée dans la turbine, à un changement inverse de phase en un liquide, qui peut être utilisé comme eau potable. Le condenseur est accouplé à une source d'un liquide de refroidissement, et la pression de la vapeur sur le côté aval de la turbine est déterminée par la température du liquide de refroidissement. Un capteur solaire flottant fournit le liquide chaud au côté amont à une température supérieure à la température ambiante normale.
