Abstract
A water desalination system including at least one pair of evaporators, said pair including a high pressure and a low pressure evaporator, each for evaporating saline water to produce water vapor; at least three adsorption beds in selective vapor communication with each evaporator, said adsorption beds arranged to reversibly adsorb the water vapor from the corresponding evaporator; said adsorption beds in selective vapor communication with a condenser, and in heat transfer communication with a heat source for selectively desorbing the adsorbed water vapor; said condenser arranged to condense the water vapor to desalinated water; wherein said system is arranged to sequentially connect, for a pre-determined period, each evaporator to a corresponding adsorption bed, and the heat source to the third bed.
