Desalination device for arid areas

摘要

The paper presents water desalination unit (WDU) based on MED-desalination method. WDU is intended for production of high quality potable water from the sea or underground water for local consumers. In hot climate areas (MENA region, Central America, South China, etc.) it could be used as the main or the only fresh water source during at least 10 months a year. The WDU could be used separately or as a part of multifunctional small scale solar system - (M4S) including also water desalinating unit and electricity unit. The main parts of the WDU (solar-thermal sub-unit, heat accumulating sub-unit and desalination sub-unit) are considered and its possible modifications are briefly discussed.
