Global water consumption grow steadily. In regions with a shortage of fresh water, its production is accompanied by a significant expenditure of energy, as a rule, it is a burning of hydrocarbon fuels. This factor has a negative impact on the environment. The aim of this work is to develop an energy-efficient “green” technology for the desalination of seawater and the production of fresh water from contaminated sources, through its forced evaporation with subsequent condensation of moisture. The process of obtaining fresh water is due to pre-saturated air in a closed thermodynamic cycle. The paper presents the thermal balance of modular installations. To increase the insolation power per unit area, it is possible to use various centers of solar energy. Experimental studies and a comparison of the performance of two variants of desalination plants in water with each other and with theoretically possible productivity were carried out. The productivity of the technologies is sufficient for the autonomous supply of drinking water to individual settlements and for the cultivation of plant foods by the hydroponic method.

At present, as a result of climate change and man-caused impact on the environment, fresh drinking quality water deficit is observed in many regions of the world. The sufficiency of fresh water provides high quality of living, the stabilization of the internal and foreign political situation, especially in developing countries. A lot of fresh drinking quality water production technologies are known today. Most of them consume a significant amount of energy and pose a considerable danger to the environment. As a source of energy, as a rule, hydrocarbon raw material is used, which is an exhaustible resource. The authors developed a technology for obtaining fresh water of drinking quality from atmospheric air using the solar energy. The article provides a substantiation of the way of fresh water production from air and also describes the energy balance in its implementation.

Climatic changes and man-induced environmental load cause to a shortage of drinking quality fresh water. Upon that, fresh water sufficiency is one of the preconditions for quality assurance in adequate living standards as well as for domestic and foreign political stability especially in developing countries. A lot of technologies of fresh drinking water production are known today. Most of them involve significant power consumption and endanger to environment. As a rule these technologies use non-renewable hydrocarbons as power source. The author-developed technology of fresh drinking water obtaining from atmospheric air involves the use of clean renewable energy of the sea. This article bases the method of water production from the air. It is also describes technology implementation energy balance.
