How the concept works :
Phase 01
The air going into the greenhouse is first cooled and humidified by seawater, which is trickled over the firstevaporator. This provides a fresh and humid climate for the crops that in these conditions need very little water as they are not stressed by excessive transpiration.
Phase 02
As the air leaves the growing area it passes through the second evaporator which has seawater flowing over it. During this phase the humid air mix with the warm dry air of the ceiling interspace. thus the air is made much hotter and more humid.
Phase 03
The warm air is forced to flow upward by the stack effect that is temperature induced. In the centralchimney the warm and humid air will condense when in contact with plastic tubes where cool sea water is pumped. In the surface of the condenser many drops of fresh water will appear, ready to be recollected in a tank to water the crops and for other uses.
