<p>PURPOSE:To improve recovery of removed water and drying characteristics by forming a circulation passage of a double-vane fan having functions of ventilation and heat exchange into a vertical doubel-construction, in which the lower section functions as a trap and a drain hole is provided in said trap. CONSTITUTION:A motor-driven double-vane fan 1 having functions of ventilation and heat exchange is divided into a circulation side section and a cooling side section. The fan 1 is enclosed by a circulation side casing 4 and a cooling side casing 3. A drain hole 9 for discharging drain is provided in a circulation passage near an exhaust port of the casing 4. And the circulation passage is formed into a double structure comprising an upper and lower sections, wherein the lower section functions as a trap 8, in which the drain hole 9 is provided. By this simple construction, recovery of removed water is enhanced and, as a result, drying characteristics can be improved.</p> |
