Abstract

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.
