Next, the operation will be described. First, in the daytime, the angle of the string 12 and the string 13 is rotated so that the surface of the light control plate 10 faces the sunlight E, and the solar cell 11 generates power. In addition, heat is stored in the heat collection space 9 by the heat generated during the power generation of the solar cell 11 and the solar heat. Utilizing this heat, the cool air of the indoor side D is sent into the heat collecting space 9 from the indoor lower air hole 8, and is returned to the indoor side D from the indoor upper air hole 7 after being heated. Can be performed. Further, by adjusting the angle of the light control plate 10, the sunlight E is collected toward the indoor side D.
