【 摘 要 】

A solar water heating system for domestic use has been designed and constructed using locally available materials. Solar energyis received by a flat-plate collector consisting of a thin absorber plate,integrated with underneath grids of fluid carrying tubes, and placed inan insulated casing with a transparent glass cover having a cold and ahot water tank integrated in the system. The radiation emitted by theabsorber plate cannot escape through the glass, thus increasing its temperature. The water gets heated and flows into a storage tank throughthermosyphon principle. Maximum fluid output temperature, the collector temperature, and insolation of 55 °C, 51 °C, and 1,480 W/m2,respectively, were obtained on a sunny day. This solar water heatingsystem finds useful application and acts as a renewable energy resourcein regions where there is abundant and consistent sunlight.
