A water desalination system includes an evaporator for evaporating saline water to produce water vapor and an adsorption means in selective vapor communication with the evaporator for reversibly adsorbing the water vapor from the evaporator. The adsorption means is in selective vapor communication with a condenser, and desorbing means for desorbing the adsorbed water vapor from the adsorption means for collection by the condenser. The condenser is adapted to condense the water vapor to desalinated water.

Apparatus and method for desalination

A regenerative adsorption process and a multi-reactor regenerative adsorption chiller assembly including a condenser adapted to receive a coolant from a source; an evaporator connected to the condenser to provide a refrigerant circuit; a plurality of reactors, each being able to operate in adsorption and desorption modes and having a coolant inlet to directly or indirectly receive coolant when operating in adsorption mode before, after or simultaneous with the condenser, and a waste heat inlet for directly or indirectly receiving waste heat from a waste heat source when operating in desorption mode; and control means for controlling said plurality of reactors such that each reactor alternately operates in adsorption and desorption modes for substantially identical time intervals, and such that each reactor has an equal chance of being the first reactor to receive the coolant when operating in adsorption mode, and the waste heat from the waste heat source when operating in desorption mode.
