The method of running water on the outer wall of the building uses a special building material that stores water on the outer wall surface, uses a pipe from a water tank on the roof to flow water on the surface of the outer wall material, and cools the building with the heat of vaporization. Although the indoor cooling effect is enhanced, the outer wall has no effect of storing water with conventional building materials. To use it in a conventional building, it is easy to adopt such as replacing the outer wall or installing water supply equipment from the rooftop. There was a problem that could not be.
In addition, the method of covering the outer wall of the building with planting has many problems in order to disseminate it widely as it requires special wall materials and the installation of water supply equipment from the rooftop, as well as the maintenance and management of planted plants. It was.

In the case of a system that cools the outer wall with heat of vaporization and enhances the cooling effect of the room, the basic idea is to cool the room with the cooling device, so the power of the cooling device cannot be significantly reduced, and the exhaust heat of the cooling device is global warming It becomes a factor of.

The cooling water to be used is supplied to the upper water storage tank in the upper part of the apparatus, and the circulation water supply mechanism provides a necessary amount to each blade of the blind part, and the surplus is accommodated in the lower water storage tank. When the amount of water in the upper water storage tank decreases, it is detected by a water level sensor installed in the upper water storage tank, and surplus water in the lower water storage tank is returned to the upper water storage tank by a circulation pump.

Since the outside air that has passed between the blades of the blind is cooled by the heat of vaporization of the moisturizing section and introduced into the room, a healthy human-friendly cool air cooling that does not require an indoor cooling device is possible.
This apparatus can be installed for each window of a conventional building, and can be installed only in a necessary room.
In addition, since an indoor cooling device is unnecessary, an effect of preventing global warming due to exhaust heat from the cooling device can be expected.

The invention's effect

The blind device according to the present invention has the effect of taking in the cooling air by the vaporization heat at the time of ventilation with constant water supply by the circulating water supply mechanism by providing a moisture retaining function to each blade surface of the blind in addition to the direct direct sunlight blocking function of the blind There is. Moreover, it can be easily installed for each window of a conventional building, does not require an indoor cooling device, and has an effect of preventing global warming effect by reducing cooling power.
