Abstract | ||||
A desalination system has been designed and fabricated. The system consists of a single slope solar distiller coupled with a solar water heating system. The Solar water heating system is working as a thermal storage system. Solar water heating system is used to collect the solar energy during day time and store it in a thermally insulated water tank. This energy is used as a heat source, when required, for the distiller. Another conventional solar distiller, utilizes only the solar energy as a heat source, has been used for comparisons with the modified distiller. Experiments have been carried out during the whole day around the four seasons. Additionally, the effect of adding Zinc Oxide nanoparticles with diameter 23~28 nm to the working fluid of the thermal storage system has been tested. Nanoparticles have been added with two different volume fractions of 0.05% and 0.1%. The results showed that, the enhancement in the productivity of the conventional distiller ranges from 46.8 % to 105.4 % with average 67 % around the year. For the storage system, the daily efficiency was 48% without nanoparticles, and, it is equal to 50.7% and 51.2% for 0.05% and 0.1% volume fractions of nanoparticles, respectively. | ||||
