Experimental study of the water depth effect and the impact of condensers connection in a new desalination system by HDH process, using solar energy

摘要

This work is part of increasing the profitability of a system of sea water desalination, single stage , held at the laboratory scale, using the method of Humidification Dehumidification ( HDH) handset, instantaneous ( shorten up the HDH cycle). This is essentially an experimental approach which consists on studying a new combination of HDH system based on the use of a plate condenser cooled by sea water and the envelope of the system cooled by the ambient air, subsequently, we test the effect of changing the water depth and the impact of condenser connection on the quantity of distilled water. The temperature of the free evaporation surface was also analyzed to determine its effect on the flow rate values of the distillate. This is a closed air system using solar energy and the cooling energy provided by the low temperature of sea water and ambient air. The results justify the feasibility of the proposed system, since we got encouraging results and quite comparable to other desalination systems using solar energy, those results also allow us to understand and predict the characteristics required for a new prototype of this desalination system.
