PLANT WITH RADIATION COOLING FOR PRODUCTION OF FRESH WATER FROM HUMID AIR Russian patent published in 2002 - IPC

FIELD: plants for production of fresh water from air with a natural cold source and forced cold pumping. SUBSTANCE: plant has solar batteries, air conduit with a fan and heat exchanger located in it, and a water catcher. The heat exchanger consists of thermosiphons with condensing and evaporation areas having a finning, the condensing area is inclined to the horizon by 30-40 deg. The fin of the condensing area is made radiating, the side of this fin facing the earth and the outer wall of the air conduit are heat-insulated, and the side of this fin radiating towards the sky has a selective coating that is transparent for infra-red radiation. The evaporation area is built in the air conduit made in the form of a Field tube. EFFECT: reduced power consumption and enhanced reliability of the plant. 2 dwg
