METHOD OF RECOVERY OF WATER FROM AIR AND FACILITY FOR ITS IMPLEMENTATION Russian patent published in 2003 - IPC

FIELD: winning of water from atmospheric air n the field. SUBSTANCE: method can be used in agriculture and at home for alternative production of sweet water. Technical result of method consists in maintenance of effective condensation of water vapors in extended zone of air flow and in design of facility which structural embodiment enables thermal interaction of air flow with cooling system to be carried out uniformly enhancing joint cooling coefficient of utilized cooling machine and amount of condensed water vapors. Apart from it method makes it feasible to purify water extracted from air from insoluble impurities and pathogenic bacteria. In compliance with method of recovery of water from air flow is formed due to pressure differential that is created right after sections of forced removal of thermal energy along direction of air flow by means of fan. Across one section of air flow forced removal of thermal energy is conducted and heat exchange between 2n heat exchange sections of air flow grouped in heat-exchange pairs of sections located on opposite sides from section of forced removal of thermal energy is organized. Heat exchange is implemented by heat transfer from i-th heat exchange section to 2n+1-i-th section, water condensate is removed from that part of air flow where temperature falls to temperature of dew point. In this case forced removal of thermal energy is conducted across at least one more section of mentioned air flow and all sections of forced removal of thermal energy are arranged between n-th and n+1-th heat exchange sections. Facility to recover water from air has conduit for transportation of air flow which houses fan, heat-removing element, collector of water condensate communicating with part of conduit and multisectional heat exchanger. Each section of heat exchanger is made of two heat exchange elements and total number of heat exchange elements is equal to 2n. Heat exchange elements included in one section are positioned on opposite sides from heat removing element, sections themselves are heat insulated one from another. Heat exchange elements are coupled in pairs along heat flow so that according to order of arrangement i-th heat exchange element is coupled to 2n+1-i-th heat exchange element. Facility also has at least one more heat removing element. All heat-removing elements are mounted in series one after another and are located between n-th and n+1-th heat exchange elements. Fan is installed in conduit between last in direction of air flow heat-removing element and n+1-th heat exchange element. EFFECT: maintenance of effective condensation of water vapors. 29 cl, 7 dwg
