Abstract
A system for extracting including a cooled condenser apparatus in contact with the volume of pressurized air being dehumidified, the condensed water being transferred into collection areas by means of capillary attraction; an evaporation chamber in thermal contact with the condenser apparatus having an inlet connected to the collection areas by means of a first valve device and an outlet connected by means of a second valve device to a space wherein the pressure is lower than that of the volume of pressurized air; and a control device for controlling the valve devices in order to carry out a control cycle with a first phase for placing the evaporation chamber under negative pressure in relation to the volume of pressurized air, and a second phase for suctioning the condensed water in the collection areas towards the decompression chamber, until the pressure in the decompression chamber reaches a predefined threshold.
