  However, in the indirect heat storage wall structure described in Patent Document 1, the space between the glass window and the heat storage wall is completely partitioned from the indoor space. For this reason, the state of the light-shielding device provided in the space between the glass window and the heat storage wall cannot be visually observed from the indoor space, and it is difficult to cope with troubles in the light-shielding device. In addition, there is a problem that the glass window cannot be directly accessed from the indoor space and the maintainability is poor. Moreover, the heat insulation performance of the roll blind itself is low, and the heat blocking effect by the roll blind is also low.

  Therefore, the present invention solves such problems of the prior art, and can easily grasp the covering state of the heat collecting surface of the heat storage wall, and has an indirect heat storage wall structure with good operability and maintainability. The purpose is to provide.

  In order to solve the above-mentioned problems, an indirect heat storage wall structure according to the present invention has a glass window provided at an opening of a building outer wall and a building having a predetermined distance from the indoor side surface of the building outer wall. A housing space is formed between the outer wall and the indoor-side surface, and a heat storage wall disposed so as to face the window surface of the glass window, and the heat collecting surface of the heat storage wall is covered and opened in the housing space. And a shielding material having heat insulation interposed so as to be free, and the accommodation space is accessible from the space on the indoor side.

  In this invention, the accommodation space formed between the indoor side surface of the building outer wall and the heat storage wall is accessible from the indoor side space. Here, “accessible to the accommodation space from the indoor side” means that, for example, a hand or the like can be put into the accommodation space from the indoor side, or the inside of the accommodation space can be visually observed from the indoor side. Thereby, it becomes possible to operate the shielding material for covering and opening the heat collecting surface of the heat storage wall easily and reliably while viewing from the indoor side, and the operability is improved. In addition, since the accommodation space can be accessed from the indoor side, the maintainability in the accommodation space is also improved.

  Moreover, it is preferable that a shielding material is plate-shaped and coat | covers and open | releases a heat collecting surface by being taken in / out of the accommodation space from the edge part of the accommodation space. In this case, it is possible to easily cover or open the heat collecting surface of the heat storage wall only by putting a plate-shaped shielding material in and out of the accommodation space.

  Moreover, it is preferable that a shielding material is a curtain form and coat | covers and open | releases a heat collecting surface by moving to a horizontal direction along the rail provided in the accommodation space. In this case, the heat collecting surface of the heat storage wall can be easily covered or opened only by moving the curtain-shaped shielding material provided in the accommodation space in the horizontal direction.

  Moreover, it is preferable that the end part of the accommodation space is provided with an openable / closable lid that defines the accommodation space. In this case, since the edge part of accommodation space can be covered with a lid | cover, the thermal storage efficiency by a thermal storage wall can be improved. Further, since the lid can be opened and closed, when the shielding material is operated, the shielding material can be visually observed by opening the lid, and the operability is not deteriorated. Further, when performing maintenance in the storage space, by opening the lid, it is possible to access the storage space, so that maintainability does not deteriorate.

  According to the present invention, the covering state of the heat collecting surface of the heat storage wall can be easily grasped, and operability and maintainability can be improved.
