う欠点があった。2. Description of the Related Art Generally, in the vicinity of the outlet of an air conditioner having a cooling function, the temperature is much lower than the temperature inside the room, so that water vapor in the air is condensed in the louver arranged near the outlet. , The phenomenon of dew condensation occurs. If the difference between the temperature in the vicinity of the louver and the temperature in the room is not large, there will be no problem of dew condensation because once evaporated, it will evaporate again, but if the temperature in the room is high such as midsummer, the louver The temperature difference between the louver and the louver increases, and steam repeatedly aggregates on the louver to form large water droplets, which eventually fall. Generally, the air outlet of an air conditioner is often installed on or near the ceiling in the room.
The drop of water droplets wets people and furniture, impairing a comfortable living environment.
【０００３】これに対する種々の対策が提案されてお

(1) A louver base material is sprayed with fibers having a length of 0.8 to 1.0 mm, and one end thereof is subjected to a flocking process to provide a heat insulating layer to prevent dew condensation, and a flocking layer.

(3) A method of controlling the air flow and reducing the dew condensation by devising the shape of the louver (for example, Jitsuko Sho 58-393).
No. 22). (4) A method of collecting and removing condensed water (for example, Japanese Patent Publication No. 61-38048).

くすことができない。However, each of the above-mentioned methods has the following technical and economic problems, and is actually less effective against drops of water drops, and has a "tanpo" shape. The current situation is to prepare a wiping tool at the place of use to prevent water droplets from falling. (1) The method of flocking the louver substrate has the drawbacks of low water absorption, lack of long-term durability (particularly weather resistance), and high cost. (2) In the method of adhering and adhering the heat insulating material to the louver base material, it is impossible to prevent water droplets from falling when dew condensation occurs, and there is no fundamental countermeasure against water droplets falling. (3) The method of controlling the air flow by devising the shape of the louver only reduces dew condensation, and is not a fundamental preventive measure against water drop falling. (4) With the method of collecting and removing the condensed water, it is not possible to completely prevent the drop of water droplets because the entire blowing portion cannot be covered.

It is manufactured by drying. The prepreg thus produced is pressurized and heated to cure the phenol resin and integrate the phenol resin and the fiber to produce the louver-forming porous material of the present invention. A flat plate can be obtained only by hot pressing, but when a non-flat plate shape is required, the desired shape can be obtained by putting the compounded product before pressing and heating into a molding die and deep drawing.
