SOLAR DISTILLER Russian patent published in 1999 - IPC

FIELD: solar energy engineering, in particular, solar plants converting solar energy into heat for desalination of mineralized water (sea water, salt water). SUBSTANCE: solar distiller has body with transparent surface, vessel with mineralized water and vessel for collection of condensate. Heat-insulated vessel with mineralized water is installed in a spaced relation to side walls and bottom of distiller body. Applied to external surface of distiller body is selective coating with low absorbing factor of solar radiation and high emissivity factor. Applied to internal surface facing solar radiation of vessel with mineralized water is selective coating with high absorption factor of solar radiation and low emissivity factor. Applied to body internal surface located above the level of vessel with mineralized water is mirror coating. EFFECT: higher productivity and intensity of heat-mass transfer process occurring in solar distiller. 3 cl, 2 dwg
