Efficiency Analysis of Solar Supported Integrated Water Heating-Distillation

In the present study, a system that combines hot water collector and distiller for the purpose of increasing efficiency in solar water heating systems and simultaneously producing distilled water is designed. Obtained results are compared with conventional solar distiller developed under the same conditions. It has been determined that in the distiller system connected with hot water collector, daily distilled water amount is 7924 ml, 4610 ml of which is during daytime and 2790 ml of which is during night-time. This developed system produces fresh and hot water simultaneously. It has been observed that hot water temperature is at appropriate levels for local usage. In conventional basin type distiller, the total water amount produced during daytime and night-time were measured as 844 ml and 1545 ml, respectively. It has been determined that the total distilled water amount produced in one day in this system is 2389 ml. Efficiencies of conventional and integrated with hot water collector distiller systems continuously increase during the day and reach at 51.47% and 77.98% levels, respectively. Compared to conventional distiller, 70% more distilled water was obtained.
