Abstract
A method for production of water from air includes cyclically and successively repeating the following two phases: a first phase a), which includes the following steps: a1) taking air from the outside, a2) conveying the air towards an enthalpic exchanger containing an adsorbent material that internally accumulates the moisture that is present in the air, a3) outputting dry air, and a second phase b), which includes the following steps: b1) supplying heat to the enthalpic exchanger by way of a low-temperature heat source, b2) conveying an air flow through the enthalpic exchanger, wherein the air in contact with the enthalpic exchanger is heated and at the same time collects the moisture contained in the adsorbent material, and b3) bringing the heated and humidified air flow to ambient temperature in order to cause the moisture contained therein to condense, thereby obtaining water.
