Atmospheric moisture precipitation apparatus for use in arid regions

Abstract

Abstract 723,239. Atmospheric-moisture precipitation apparatus. BRITISH ELECTRICON (LONDON), Ltd. Feb. 27, 1953. [Feb. 28, 1952 ; April 29, 1952] Nos. 5267/52 and 10797/52. Class 64 (3). Apparatus for precipitating moisture from the atmosphere comprises a chamber bounded above by a metal plate of high thermal conductivity with an upper surface which is a good radiator, the chamber having inlet and outlet openings which, when the upper surface of the plate is losing heat by radiation, permit a restricted stream of air to enter the chamber, become cooled and deposit moisture, and then by convection leave the chamber at a lower level, while the moisture is collected by the lower walls of the chamber and directed to a receiver. In the form shown, the precipitating chamber 2 comprises saucer shaped members 4, 6 spaced slightly apart to leave a passage 10 for the entry of air. The member 4 is of copper or aluminium and its upper surface is blacked to increase its radiating properties and fin members 8 project from its inner surface into the chamber 2. The member 6 is provided with an outlet 12 for air and condensed liquid leading to a receiver 14 e.g. a vacuum flask in which the liquid collects and which is slightly spaced from the member 6 to allow air to escape. The radiating surface of the chamber 2 may be convex (as shown), concave, 'or flat and the vacuum flask may be sunk in a pit in the ground. According to the Provisional Specification, a filter may be provided at the outlet from the chamber 2.
