A PIONEER SYSTEM OF SOLAR WATER DESALINATION
A pioneer system design of solar water desalination was developed and constructed for moderate latitudes, Cairo 30 °N. The humidification/dehumidification (HD) process is considered in this system. The salt water is heated by either solar energy or auxiliary heater before injection inside an insulated desalination chamber using an air atomizer. The air is supplied into a condenser by a blower and later on it pulls hot salt water up through the atomizer from an insulated tank. By this idea the air is preheated inside the condenser and is used as a water pump. The flashing water is evaporated and condensed simultaneously above the condenser surface. A 2.39 m2 flat-plate solar collector is used to heat the salt water existed in the tank. The tank opening is closed by the chamber one. By this way the salt water is circulated naturally inside the solar water heater where it is forced to be evaporated. The system was successfully tested using either solar or auxiliary energies where it is more efficient if a combination of them is provided. It can produce about 36 liter daily of purified water where the using of solar energy alone can obtain about 15 liter on clear days. One liter of distilled water can cost about 0.06 US$ using the considered system.
