Title: Feasibility study of a solar and wind powered desalinization device (SOWIDE). Final report

Abstract

The scope, need and feasibility of a solar-wind desalinization (SOWIDE) system is examined. A climatological study shows the scope and need where a water deficit, a saline source and solar and wind power coincide. Representative stations around the globe serve as examples. When climatological data are used, relatively few locations meet all requirements. Optimization of wind and solar energy through careful site selection would, however, greatly extend the use of an alternate energy powered desalinization system such as SOWIDE. The technical feasibility of SOWIDE is described in terms of the conceptual design which uses solar energy to heat impounded water, saturating a volume of air above the impoundment at the temperature of the water. The water vapor is extracted by condensation through a wind powered refrigerator. Latent heat is returned to the impoundment by the refrigerator fluid with additional heat provided by a pre-heater using heat from the brine discharge and by a resistance heater or stirrer driven by the wind generator. The important considerations of the design include the joint use of solar and wind power, optimization of the heat balance and the fact that the system operates at a low temperature which inhibits scaling and efficiency losses. Resultsmore » show that the system will deliver 1 m/sup 3/ d/sup -1/ of fresh water at operating temperatures of 42 to 70/sup 0/C. At an operating temperature of 60/sup 0/C, the total power required is about 8 kW, equally partitioned between the solar and wind inputs. The operating temperatures and power requirements suggest that the SOWIDE system is technically feasible. Application of the system must await the testing of a prototype and an economic study.« less
