Solar stills of inclined evaporating cloth

摘要: Abstract This article describes various solar stills with inclined evaporating surfaces. It also discusses theoretical studies of maximum annual energy absorbed in fastened plane surfaces or adjustable slope, which have been performed at the University Santa Maria, Valparaiso, Chile. The has studied efficiency cloth oriented to sun several ways. relation arrangement radiation: transfer and absorption coefficient rays, thermal insulation, distances between surface transparent cover, vapor leaks, enthalpy loss due brine output, wind were determined. influence time on still material is discussed. Factors included are aging plastic covers (Oro T polyethylene, polystyrene, metacrylic polyester, etc.), alterations suffered by different types cloths (yute, malva, canamo, insoluble salt deposition, seals (organic inorganic cement, neoprene, etc.). economics developed Chile considered. includes costs materials, construction maintenance stills, specific production cost distilled water locations.
