Patent abstract
A water vapor ejector comprises a desiccant disposed in a communication path to a green house enclosure. In the day time and under sunlight exposure, the green house enclosure heats up, which dries the desiccant and generates a flow to the outside ambient through a pressure difference. The moisture trapped in the desiccant is then released to the outside ambient. In the night time, the green house enclosure cools, which generates a flow to the inside of the enclosure. The desiccant traps the moisture within the flow, ensuring a moisture-free enclosure. The cycle re-starts in the next morning when the enclosure heats up. The diurnal cycle removes the water vapor present in the enclosure and delivered to the exterior of the enclosure.
