Desalination apparatus comprising a vessel, an evaporation surface for receiving saline water in the vessel, a condensation chamber arranged in the vessel beneath the evaporation surface, an evaporation chamber arranged in the vessel above the evaporation surface, a fresh water tank for containing a reservoir of fresh water and fresh water vapor thereabove, a first conduit connecting the fresh water tank and the condensation chamber, a pump for compressing in the condensation chamber fresh water and fresh water vapor to maintain a pressure-temperature differential between the condensation chamber and the evaporation chamber at the evaporation surface, a second conduit connecting the evaporation chamber and the fresh water tank for removal of fresh water vapor from the evaporation chamber and its delivery to the reservoir of fresh water, and valves and conduits for conveying saline water to the evaporation surface and for taking off fresh water accumulated in the fresh water tank. The invention also includes a process for converting saline water to fresh water by compressing fresh water vapor in a condensation chamber to create a pressure-temperature differential between the condensation chamber and an evaporation surface arranged above that chamber, by vaporizing fresh water droplets separating from the saline water in an evaporation chamber arranged above the evaporation surface, and by transferring the fresh water droplets to a fresh water reservoir in a fresh water tank.
