<p>PURPOSE:To improve the recovery efficiency of removed water by providing a plurality of groove extending radially in the same direction as that of rotation of a double-vane fan on the side, facing a circulation side, of a partition plate which separates the fan into a circulation side and a cooling side. CONSTITUTION:A double-vane fan 1, which is driven by a motor 5 and has a function of ventilation and heat exchange, is divided into a circulation side and a cooling side by means of a partition plate 2. The fan is is enclosed by a circulation side casing 4 and a cooling side casing 3. A plurality of grooves 6 extending radially in the same direction as that of rotation of the fan 1 are provided on the side, facing the circulation side, of the plate 2. By this simple construction, the moisture which is condensed by heat exchange and attached to the side of the plate 2, facing the circulation side, is prevented from seeping to the cooling side, facilitating the recovery of the moisture, resulting in improved recovery of removed water.</p> |
