Investigation of a novel small-scale solar desalination plant (original) (raw)

The investigation of a novel solar energy desalination plant is the subject of this paper. In this plant, the evaporation occurs at low pressure and temperature. The novelty of the process lies in the reduction of the pressure simply due to the height of the evaporator. A mathematical model was developed and a prototype plant was constructed and tested by varying the heat input, evaporator pressure and feedwater flowrate at different working temperatures. Experimental results are very close to the theoretical results and indicate the validity of the model and the potential of the system.
