Development of a Solar Water Distiller with a Receiver and Condenser

Abstract

The solar water distillation distills brackish water, which can mitigate the demand of pure water for the human beings. This study proposes a solar water distiller with a condenser and collector made from a tube bank. The receiver and condenser are connected by the rubber tubes. The brackish water from a tank flows along with condenser. The water temperature is relatively low, so this tube bank acts as a condenser for the water vapor that evaporates from a water basin of the distiller. It is believed that this can increase the condensation rate of the system. After passing through the condenser, the brackish water flows up along the receiver and its temperature is increased. Then the water continuously flows to the basin. According to the experimental results, the water’s temperature in the proposed system is higher than that of the conventional distiller. This leads to the higher productivity of the proposed system (approximately 3.3 L/m2 day). In addition, it was found that the temperature of the condenser of the proposed system was lower than that of the top cover of the conventional system.
