Abstract
The invention relates to apparatus and method for efficiently removing humidity from a chamber. A thermoelectric cooler with a maintained temperature differential between the cool and warm sides of the cooler is used to condense the humidity from within the chamber upon the cool side of the cooler. The condensate is transferred to the warm side of the cooler and then removed through the capillary penetration into a porous structure of an evaporator at the warm side of the cooler and further evaporation. During evaporation, the condensate extracts heat from the warm side of the cooler, the temperature of the cool side of the cooler being also decreased, which results in an increase of the overall efficiency of the apparatus.
