Kind Code:
B2
Abstract:
To provide a louver device capable of performing radiant air conditioning by radiating heat while efficiently performing collection of sunlight.SOLUTION: A louver device installed in an air layer 3 formed between an external glass 1 and an internal sash 2 of a double-skin structured glass curtain wall, includes: a plurality of heat collecting tubes 5 through which a heat medium passes; and a plurality of shading plates 4 each of which has a reflection surface 7 formed facing the heat collecting tube 5 configured to rotate around the heat collecting tube 5. Each of the heat collecting tubes 5 is attached to a support member 13 of a curtain wall via support members 10, 11, and each of the shading plates 4 is supported rotatably by the support members 10, 11. When the reflection surface 7 of the shading plate 4 is oriented to the external glass 1 side, the sunlight directly hits the heat collecting tubes 5 and is reflected by the reflection surface 7 toward the heat collecting tube 5, and the heat collecting tubes 5 collect the heat from the sunlight. When the reflection surface 7 of the shading plate 4 faces the internal sash 2 side, the heat radiated from heat collecting tube 5 is reflected by the reflection surface 7 and radiated indoors.SELECTED DRAWING: Figure 2
