Apparatus for simultaneously recovering fresh water and salt or concentrated saline solution by direct collection of solar energy through special energy elements. Each energy element consists of two substantially horizontally arranged foils (10, 20), which in longitudinal direction of the elements are jointed in several places in the transverse direction, so that each element includes a plurality of longitudinal gaps (11, 12, 13, 14) for sea water transport. Each of the energy elements is attached mechanically at one end to an inlet (18) for sea water and at its remaining end (17) attached mechanically to an inlet on an evaporation chamber for the recovery of fresh water in known manner. By the invention large surfaces for solar radiation are obtained with little material consumption, thereby rendering the elements cheaper than conventional elements. The foils (10, 20) preferably are made of a black plastic material, which implies high energy absorption capacity, low weight and absence of corrosion problems. |
