Abstract

PURPOSE:To remove humidity via the ventilation of a room and an attic by communicating a natural lighting window to the room via a light introduction duct, and introducing humidity to an area between the duct and the attic via the humidity permeable plate of a vent valve for adjusting an air flow quantity through an air introduction plate. CONSTITUTION:A frame 6 for erecting a ventilation cylinder 5 is provided with a drip cap 7 or a blind window 3, and the louver board 4 of the blind window 3 is rotated with a rotational shaft, thereby adjusting a ventilation volume. In this case, a solar battery 1 laid on the upper surface of the cylinder 5 drives a fan 2 to facilitate ventilation, and divisions 17 are provided to keep a natural lighting window 4 and a room 18 communicated with each other. Furthermore, light is introduced to the room 18 via a light introduction duct 8, and an area from the duct 8 and the cylinder 5 to a ventilated attic 9 is made continuous with the vent valve 16 for the divisions 17. In this case, the vent valve 16 is fitted with a plurality of air introduction plates 10, and an air flow quantity is adjusted on the rotation of the plates 10. Furthermore, a humidity permeable plate 15 is laid in the valve 16 to release humidity outdoors and a spring 11 of shape memory alloy is deformed at the preset temperature. As a result, the plate 15 comes in contact with and parts from the air introduction plates 10, thereby opening or closing the valve 16 and adjusting the air flow quantity.
