[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar heat collecting part of a solar system house which utilizes solar energy by air.

[0002]

2. Description of the Related Art It has long been practiced to take a large opening on the south side of a house to take in a large amount of solar radiation in winter and to open a part of it in summer to ventilate the air. Taking this one step further, it is also practiced to create a solarium outside the living room and use it as a greenhouse to take in warm air from here. The applicant has previously proposed and filed a solar system house that can reasonably promote this and can effectively utilize the air collected by sunlight regardless of the direction. Japanese Patent Application No. 61-311485 (Japanese Patent Application Laid-Open No. 63-165633) and Japanese Patent Application No. 62-234666 (Japanese Patent Application Laid-Open No. 64-75858).

The outline will be described with reference to FIG. 4. An air flow path 2 having a roof slope is formed immediately below a metal roof plate 1 such as a colored iron plate as a solar heat collecting portion, and one end of this air flow path 2 is formed. The outside air intake 3 is opened at the eaves and the like (which may be the back of a hut), and the other end is connected to a ridge duct 4 as a heat collecting box made of a heat insulating material. The lower surface of the air flow path 2 having a roof slope formed directly below the metal roof plate 1 such as a colored iron plate is configured as a heat insulating layer spread with glass wool or the like, and a part of the roof is covered with glass 23. did. The glass 23 prevents the wind from interfering with the heating of the metal roof plate 1 by solar heat by cooling when the wind is strong.

A backflow prevention damper 6, a fan 7 and a flow path switching damper 8 are provided inside, and the flow path switching damper 8 is provided.
On one side of the outflow side, the handling box 5 that is opened to the outside by the exhaust duct 9 is installed in the attic 22 which is the attic space, and the inflow side of the backflow prevention damper of this handling box 5 is communicated with the ridge duct 4 One of the outflow sides of the path switching damper 8 is connected to the upper end of the falling duct 10. The lower end of the descending duct 10 is an air circulation space between the heat storage soil concrete 11 and the floor panel 12 as a heat storage / radiation unit.
A floor outlet 14 opening from the air circulation space 13 to the room
Was set up.

As described above, the inflow side of the backflow prevention damper 6 of the handling box 5 is connected to the ridge duct 4, and the inflow side of this backflow prevention damper 6 is connected to the circulation duct 19 that opens into the room such as the ceiling. The backflow prevention damper 6 is also configured as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 19 side.
If the room provided with the suction port 20 in which the circulation duct 19 is open is the second floor, there is a floor panel 12 provided with the floor outlet 14 to the room on the first floor, and the room has an air blow-through structure. It is desirable to allow free flow.

In the handling box 5, a hot water coil 15 is provided between the backflow prevention damper 6 and the fan 7.
The hot water removing coil 15 is connected to a hot water storage tank 17 by a circulation pipe 16. In the hot water storage tank 17, a hot water supply boiler 18 for additional heating is provided on the way to connect a hot water supply pipe 21 to a bath, washroom, or kitchen.
Connect.

In this way, the roof plate 1 which is a metal plate heated by sunlight warms the outside air entering the air flow path 2,
This warmed air rises along the roof slope. Then, this heated air is collected in the ridge duct 4, then enters the handling box 5 by the fan 7, flows down from the handling box 5 in the falling duct 10, and the air circulation between the heat storage soil concrete 11 and the floor panel 12 is performed. Enter Space 13. In this air circulation space 13, the heated air directly heats the bottom of the floor through the floor panel 12, and the heat storage soil concrete 11
Heat is stored in the room and is directly blown into the room from the floor outlet 14 as warm air.

On the other hand, the hot water removing coil 15 heats the water fed from the hot water storage tank 17 through the circulation pipe 16 to the hot water removing coil 15,
It is stored in the hot water storage tank 17 as hot water, and is further reheated from here by the hot water supply boiler 18 for additional heating to supply hot water to various places from the hot water supply pipes.

By the way, in a season such as summer when there is no need for heating at a high temperature, it is necessary to discharge all the heated air heated by the roof plate 1 to the outside air and dispose of it. In that case, if the flow-path switching damper 8 closes one of the outflow side, that is, the falling duct 10 side, and opens the other, one of the outflow side, the exhaust duct 9 side, the heating air from the handling box 5 is exhausted. Abandoned outdoors via 9. Since the heated air passes through the handling box 5 to heat the hot water removing coil 15, it can be ensured that hot water can be obtained by utilizing solar heat even at high temperatures such as in summer.

[0010]

As described above, in the solar system house shown in FIG. 4, heat is an energy-saving system in which heat is collected by the light of the sun, but electricity is consumed for driving the fan 7 and controlling the opening / closing of the damper. If this electricity is provided by solar power generated by solar cells, it will result in an energy-saving system that uses solar energy more effectively, but the location where solar cells are installed is selected on the roof that is most susceptible to sunlight. Then, this solar cell blocks the sunlight that warms the roof plate 1 and hinders the heat collecting action at the corner.

On the other hand, if a solar cell is installed on the ground or the like, it is difficult to secure a space, and the cost for installation work of the mount is added.

The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional examples, in which a solar cell is incorporated into a roof plate which is a building material,
By integrating it, it is possible to obtain solar heat at the same time as electricity, for which there is no need to provide a special installation place for solar cells, and it does not hinder the heating of the roof panel by sunlight, and the roof Since the structure itself can be used as a stand for solar cells, the cost of the stand can be saved,
It is an object of the present invention to provide a solar heat collecting part of a solar system house, which can save the cost for installation work of a solar cell because the installation of the solar cell is completed at the same time when the roof is constructed.

[0013]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is to roof a roof with a stack of solar cells,
An air flow path having a roof slope is formed immediately below the roof plate, and the roof plate has a roof steel plate and an amorphous silicon solar cell laminated on the roof steel plate, and the surface of the amorphous silicon solar cell is made of a resin. The gist is that it is coated.

[0014]

According to the present invention as set forth in claim 1, the solar cell constitutes the solar cell module integrally with the roof plate, and the heat collection by the roof plate and the power generation by the solar cell can be performed simultaneously. it can. At that time, the efficiency of the solar cell is several percent of the acquired solar energy, and the solar heat collection performance is not substantially affected.

According to the second aspect of the present invention, the amorphous silicon solar cell constitutes a solar cell module as an integral type with a roof steel plate, and has a strength backed by the roof steel plate. Becomes Therefore, this solar cell module can be bent upward and downward, and depending on the bending angle, bending the power generation part of the solar cell does not impair the function of the solar cell, and it can be bent in various styles and forms. It can be applied to roofing materials.

Further, in an amorphous silicon type solar cell, although the power generation with temperature rise is relatively small, there is an air flow path having a roof slope directly below the roof plate, and the air flowing therethrough makes the roof plate constant. Since the temperature does not rise above the temperature, the power generation performance can be maintained.
