METHOD FOR PRODUCTION OF WATER FROM AIR AND DEVICE FOR ITS IMPLEMENTATION (OPTIONS) Russian patent published in 2023 - IPC E03B3/28 

FIELD: water production.

SUBSTANCE: group of inventions relates to the field of production of fresh water of drinking quality from moisture of ambient atmospheric air. The method consists in formation of an airflow containing water vapor, its artificial cooling, condensation of water vapor into fresh water, and supply of a condensate to a water collection tank. The formed airflow is sprayed in water, after which the resulting water-air mixture is compressed, heat of compression is removed from it into the environment. Further, pressure of the cooled mixture is sharply reduced, and a condensate obtained from air cooled during expansion is supplied to a free part of the water collection tank. According to the first option, a machine for production of water from moist air contains an air intake device made in the form of a fan, a refrigeration unit, and a tank for collecting a condensate released from air. The refrigeration unit is made in the form of a liquid pump, a suction line of which is connected to a condensate collection tank. An injection line is equipped with a device for mixing water with air, a heat exchanger, and a nozzle with an outlet to the condensate collection tank. According to the second option, in the machine, the refrigeration unit is made in the form of a piston or rotary type pump-compressor, and it contains pumping and compressor cavities. A suction line of the pumping cavity is connected to the condensate collection tank. A suction line of the compressor cavity is connected to the atmosphere. Injection lines of pumping and compressor cavities are connected to the device for mixing water with air. According to the third option, in the machine, the refrigeration unit is made in the form of a piston pump with a piston, a cylinder, a drive mechanism located in a crankcase, having suction liquid valves in an upper part of the cylinder, connected to the condensate collection tank, suction gas valves connected to the atmosphere and located in a bottom of the piston, and injection valves located in the upper part of the cylinder, connected to the injection line connected to the condensate collection tank via the heat exchanger and the nozzle. An under-piston space is connected to the atmosphere via a check valve installed in the crankcase of the machine.

EFFECT: reduction in dimensions and weight, simplification of equipment maintenance, and improvement of overall economic and thermodynamic efficiency are provided.
