APPARATUS FOR PRODUCING LIQUID WATER FROM AMBIENT AIR BY ADSORPTION AT NIGHT AND DESORPTION DURING THE DAY

摘要

The invention relates to an apparatus (10) for producing liquid water from ambient air, comprising a lower frame (11) and an upper cover (12) defining an inner space (13) between them, and at least one air inlet (14) in the lower frame (11). An adsorption and desorption module (16) is arranged in the inner space (13) above the air inlet (14) with a bed of adsorbent material (17) for the adsorption and the desorption of water molecules in relation to the ambient air and solar energy collection elements (18) generating calories from the inner solar flux and thermally transferring the generated calories to the adsorbent material (17). A ventilator (21) varies between a first mode in which it imposes vertical forced circulation, from bottom to top, of the ambient air taken in by the air inlet (14), and a second mode in which the upper cover (12) acts as a condenser for the ambient air of the inner space (13). A valve (22) is arranged in the upper cover (12) to allow the ambient air to flow from the inner space (13) to the outside environment when the ventilator (21) is in the first mode, the valve (22) being otherwise closed. An electronic unit switches the ventilator (21) selectively into the first mode during a period of night time and into the second mode during a period of day time, said switching being performed according to predetermined criteria.
