APPARATUS FOR EXTRACTING WATER FROM AIR BASED ON SOLAR MODULE WITH PARABOLIC CONCENTRATOR AND STIRLING ENGINE Russian patent published in 2019 - IPC E03B3/28 B01D5/00 

FIELD: physics.

SUBSTANCE: invention relates to devices for obtaining fresh water from atmospheric air using renewable energy sources. Proposed plant comprises housing with air inlet and outlet openings with heat circuit arranged inside the housing with cruising coolant, condenser and evaporator to condense moisture and water collector. Plant is additionally equipped with a solar module consisting of a parabolic concentrator and a Stirling engine, which creates a focal region on the surface of the cylindrical photodetector. In the lower part of the Stirling engine there is a cooling device, and in the housing filled with soil forming a hill there installed is a hydraulic pump, two hydraulic motors, a fan, a compressor, pumping cooling agent along the thermal circuit. Stirling engine is connected via crank-and-rod mechanism with hydraulic pump, which is connected by pressure lines with hydraulic motors, on shaft of one of which there is a fan, and other hydraulic motor is connected to compressor. Lower part of the heat circuit with the condenser and the compressor is buried in the ground, and the upper part of the heat circuit with the evaporator is located inside the housing. Under the evaporator there is a water collector, in the lower part of which a water line is installed, which delivers extracted water to the consumer.

EFFECT: higher efficiency of obtaining fresh water from atmospheric air using solar energy with low cost.
