METHOD FOR EXTRACTING WATER FROM AIR AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

The extraction of water from ambient air comprises forming an air flow (1) and forcibly removing heat energy on at least two portions (2) of the flow. All portions for forced removal of heat energy are located between n and n+1 heat-exchange areas (3n, 3n+1). Afterwards, heat exchange is performed between 2n heat-exchange sections (31, 32n) of the air flow. The sections are grouped into heat-exchanging pairs of the sections arranged on the opposite sides of the portions (2) for the forced removal of heat energy. The heat exchange is performed by a heat transfer from i heat exchange section towards a 2n+1-i heat exchange section. A water condensate is extracted from a part of the air flow where the temperature is lowered to the dew point temperature.
