Embodiment Construction

[0076] The description that follows sets forth numerous specific details that may facilitate an understanding of some examples of one or more embodiments. Embodiments may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances some known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the embodiments. In this specification, any reference to "an embodiment" will mean that a particular arrangement, structure or feature is included in at least one embodiment. Thus, the phrase "in an embodiment" and other similar phrases that may appear in different parts of this specification will not necessarily all refer to the same embodiment. Furthermore, any particular arrangement, structure or feature may be combined in one or more embodiments as deemed appropriate.

[0077] Therefore, the following references are for the purpose of simplification only, and do ...

Abstract

A method for production of water from air comprises 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 (EHX) containing an adsorbent material (MAT_AD) that internally accumulates the moisture that is present in the air, a3) outputting dry air, anda second phase b), which includes the following steps: b1) supplying heat to the enthalpic exchanger (EHX) by means of a low-temperature heat source, b2) conveying an air flow through the enthalpic exchanger (EHX), wherein the air in contact with the enthalpic exchanger (EHX) is heated and at the same time collects the moisture contained in the adsorbent material (MAT_AD), 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.

Description

technical field [0001] The present invention relates to the technology of extracting water from the atmosphere by mainly utilizing low temperature heat. [0002] In more detail, the present invention solves the problem of low water resources, which plagues the world, through an efficient and economical method of extracting water from the atmosphere primarily using low temperature heat (such as generated by solar thermal systems) many countries on the [0003] The present invention proposes a method for extracting water from the atmosphere, based on an innovative thermodynamic cycle. [0004] Furthermore, the present invention proposes a compact system for carrying out said circulation, dimensioned to satisfy the drinking and sanitary water needs of a family or a group of people. [0005] This cycle requires the use of extremely economical technical and energy resources, so it is also advantageous for small-scale applications, such as for supplying water to individual househo...
