Abstract: The invention relates to a device for generating water by condensation of the ambient moisture contained in the ambient air surrounding a thermally insulated sealed case housing a means for maintaining a low temperature. The invention also comprises a coil means which is divided into numerous segments, of which some pass through the interior of the sealed case and others extend externally around all sides thereof, such as to form a closed circuit with a receptacle containing an anti-freeze heat-transfer liquid. The invention further comprises a pulse pump which is disposed in the circuit, a cooler which cools the interior of the sealed case when the internal temperature rises and a turbine for driving air into the case. The assembly is enclosed in an external casing and is equipped with a tray for collecting the condensed water.
