Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat utilization structure, and more specifically, a solar heat collector is installed using an external wall other than the window openings on the outside of a floor slab of a building, and an existing building is renovated. Concerning the exterior walls of a building that utilizes solar heat.

The conventionally known structure is to construct a double-glazed window consisting of two inner and outer glass panes in the window opening of a building, and install a solar heat collector in the space between the opposing glass panes. Ventilation holes communicating with the indoor side are provided at the top and bottom of the section. In use, if both vents are left open during winter sunshine, low-temperature indoor air flows into the space from the lower vent, is heated by the heat collector, and warmed air rises inside the space. The air enters the room through the upper vent and is used to heat the room. Also, at night, both the upper and lower vents are closed to prevent air convection between the room and the space, thereby preventing low-temperature air in the space cooled by outside air from flowing into the room. However, such double-paned windows have a complicated and expensive window structure, require replacing existing windows with double-paned windows, and also have a heat collector in the window, which reduces daylight. There were other drawbacks.

The present invention has been made in consideration of the above-mentioned drawbacks, and includes providing a light-transmitting plate on the outside of the wall at the outer edge of the floor slab of an existing building, and a reflecting plate on the outside of the wall inside the light-transmitting plate. To provide a structure in which air heated by a blind solar heat collector provided in the space is used for indoor heating. According to the present invention, solar heat irradiated onto the outer wall surface can be effectively taken in with a simple structure, which is useful for energy saving.

The present invention will be explained below with reference to Examples.

1st Example (Figures 1 to 4) The frame made of reinforced concrete, etc. is a floor slab 1
It is formed with a wide wall portion 2 perpendicular to the T-shape. The wall portion 2 is located at the boundary between the upper and lower floors of the building, and a window portion 3 is provided between each wall portion of the upper and lower floors.
Transparent plates 4 made of glass or the like are disposed parallel to the wall 2 of the existing building formed in this way and at a predetermined interval in the direction toward the outside, so that the wall 2 and the transparent plate 4 can be connected to each other. A sealed space 5 is formed between the space 5 and a solar heat collector 6 in the form of a roll blind, for example, is installed in the space 5 over almost the entire area of the transparent plate 4.
to be hung.

In particular, as shown in FIG.
It is designed to be rolled up on a top box 7 arranged at the top of the box, and a solar heat ray absorbing surface such as black coating is formed on the outer surface. Reference numerals 8 and 9 indicate upper and lower ventilation holes drilled in the wall 2. The lower ventilation hole 9 introduces and collects air that has become hot due to lighting equipment near the ceiling of the lower floor into the space 5. It is heated by a heater 6 and then sent to the ceiling of the upper floor through a conduit 10 from an upper ventilation hole 8 to assist in indoor heating of the upper floor. When the conduit 10 is long, a suction blower (not shown) may be used as appropriate. Rope holes 1 are provided in the wall 2 so that the roll blind heat collector 6 can be operated from the indoor side.
1 is bored and a rope 12 for operating the heat collector is inserted through it. A heat ray reflecting surface 13 made of aluminum foil, white paint, etc. is formed on almost the entire outer surface of the wall portion 2. This reflective surface 13 prevents the inside of the building from becoming high temperature by winding up the heat collector 6 and reflecting solar heat rays to the outside of the building when heat collection is unnecessary, such as during sunshine in summer. With the above configuration, the air preheated on the lower floor is reheated by the heat collector 6, resulting in high heating efficiency. still,
Providing the cover 14 over the lower ventilation hole 9 is advantageous because indoor air will not flow into the space 5 when the space 5 becomes cold at night or the like.

In FIG. 3, conduits 10 disposed on both sides of an indoor partition wall 15 are covered with covers 16 to prevent deterioration of the aesthetic appearance of the room.

The window portion 3 is provided with an existing sash or a new sash. New sashes are mainly installed when existing sashes do not have ventilation holes above or below. That is, in any case, there are upper and lower ventilation holes 17 on the upper and lower sides of the window part 3.
and 18 (indicated by a small sliding shoji screen in the drawing)
A window or sash 19 is provided. Translucent plates 20 are arranged approximately parallel to this sash 19 and at a predetermined interval in the outdoor or indoor direction (in the drawing, in the outdoor direction), and there is a space between the sash 19 and the translucent plate 20. part 21 and this space part 2
A heat collector 22, for example, in the shape of a Benen blind is suspended within the top box 22A over almost the entire area of the light-transmitting plate 20. The above heat collector 22
A plurality of slats 23 are arranged in parallel while maintaining appropriate inclination angles, and the upper surfaces of the slats can be used as heat collecting surfaces when used in winter, and can be used as reflective surfaces when used in summer. In addition, one side of the slat is formed as a heat collecting surface and the other side is formed as a reflective surface, and the slat surface is used by reversing it depending on the winter or summer, or the first slat has a heat collecting surface on the upper surface and a reflective surface on the upper surface. The second slats are arranged alternately, and in winter, each second slat is pulled up to the lower surface of each first slat adjacent above it, and in summer, each second slat is raised to the lower surface of each first slat adjacent below it. It is also possible to lower the upper surface and use the upper surface of all the slats as a heat collecting surface or a reflective surface. The low-temperature air entering the room through the lower ventilation hole 18 is heated by the heat collector 22 in the space 21 and rises, and enters the room through the upper ventilation hole 17 and contributes to heating.

Second Embodiment (FIGS. 5 and 6) In this embodiment, the space 5 between the wall 2 and the transparent plate 4 and the space 21 between the window 3 and the transparent plate 20 are vertically connected to each other. It is connected to. In this case, the ventilation holes are not provided individually for both spaces as in the first embodiment, but the low-temperature indoor air that enters the space 5 through the ventilation hole 9 rises and enters the space 21 through the window. The room is entered through the upper ventilation hole 17 of the section 3. Both spaces 5
and 21 communicate in the vertical direction, the two heat collectors 6 and 22 can be used in common, for example, to form one roll blind. In this embodiment, the warm air is directly guided indoors through the ventilation hole 17, but it can also be guided to the ceiling of the room using a conduit (not shown). In addition, when separate heat collectors 6 and 22 are used in the spaces 5 and 21 as shown in the figure, a mesh (not shown) or the like is provided at the boundary between the two spaces so that the objects from the space 21 to the space 5 are It is convenient to prevent objects from falling.

Third Embodiment (Figures 7 to 9) In this embodiment, for example, wall portions 2 and window portions 3 are arranged alternately in the vertical and horizontal directions of a building.
A heat collector 6 is also provided on the wall between the windows in the horizontal direction.

The present invention is configured as described above, and a transparent plate is attached to the outdoor side of the wall at the outer edge of the floor slab, a space is formed between the wall and the wall, and a heat collector is disposed within the space. The structure is simple and construction costs are low. In addition, the heat reflective surface of the wall allows the blind-like heat collector to be rolled up when heat collection is not necessary, and the reflective surface reflects the heat rays to the outside, preventing the indoor temperature from becoming high. can do. It is effective because it makes use of the above-mentioned walls of buildings that normally have no use value, and since the work is carried out on the outside of the building, it is easy to carry out construction work that also serves as the renovation of the exterior of an existing building. Furthermore, since the wall portion is double layered, it has soundproofing and heat insulation effects, and can be used not only for building construction but also for single-family houses and apartment complexes, and has many other effects.
