<p>The method comprises spraying saline water by a droplet producer into droplets with size pre-determined for large part of a pre-defined size area, where the droplets are sprayed in an extensively surrounded moistening area and evaporate to parts, passing air through droplet loaded moistening area by which the air is moistened, using the moistened air as inlet flow for the operation of an air condensation plant in which the moisture contained in the air condenses to fresh water, and operating a solar processing plant for direct flowless cold generation for the air condensation plant. The method comprises spraying saline water by a droplet producer into droplets with size pre-determined for large part of a pre-defined size area, where the droplets are sprayed in an extensively surrounded moistening area and evaporate to parts, passing air through droplet loaded moistening area by which the air is moistened, using the moistened air as inlet flow for the operation of an air condensation plant in which the moisture contained in the air condenses to fresh water, and operating a solar processing plant for direct flowless cold generation for the air condensation plant. The plant for the cold generation comprises solar collectors for producing thermal output, and cold machines that are coupled to the exit of the collectors. The heat output transforms into cold output for the air condensation plant. The moistening step is intensively operated so that the air to be condensed is moistened in such a way that its dew point temperature is increased and the collectors and/or cold machines are operated with high Carnot coefficient of performance. The air to be condensed at the exit of the moistening area possesses a relative humidity of more than 90%. The cool temperature of the condenser plant is adjusted at 20[deg] C or more. A mist eliminator is switched between the exit of the moistening area and the inlet of the air condensation plant. The flow and the droplet size are adjusted in the moistening area so that no droplets are available in the air at the outlet of the moistening area. The mist eliminator separates the saline water droplets. The droplet producer is formed through nozzles, which are formed in the moistening area in such a way that the droplet size is pre-adjusted and the flow is adjusted in such a way that a large portion of the droplets is dropped to base before the droplets reach the outlet-opening (25). The moistening area is formed through a tent-like building construction and spraying nozzles are mounted on the tent linkage into its upper area. The droplet size is adjusted so that the droplet at the outlet possesses a size, which is separated with an efficient grade of given height in the downstream mist eliminator. The relative humidity of the moistened air is driven so that its dew point adjusts itself in such a way that the air condensation plant is operated with a high cooling temperature. The solar collector is used and operated in a simple construction method. A module consists of collectors from a carrier plate with absorption layer, and a cover plate permeable for sun light and infrared radiation, together with edge welts for carrier plate. Spacers are distributedly arranged over the surface of the module and a given interval adjusts between the absorption layer and the cover plate. The intermediate area is filled with a fluid heat carrier medium. An inlet opening (23) is provided for the supply of relatively cold heat carrier medium and an outlet opening is provided for the discharge of relatively hot heat carrier medium. Independent claims are included for: (1) a plant for obtaining fresh water; and (2) a solar collector.</p> |
