Description of the Related Art It has long been practiced to open a large opening on the south side of a house to receive a large amount of winter solar radiation and to open a part of it in summer for ventilation. Taking this one step further, a sunroom is created outside the living room, and this is used as a greenhouse to take warm air from here into the living room. The applicant has previously proposed and applied for a solar system house that promotes this reasonably and can effectively use air collected by sunlight without being limited to the direction. Japanese Patent Application No. 61-31485 (JP-A-63-16)
No. 5633) and Japanese Patent Application No. 62-234666 (Japanese Patent Application Laid-Open No. 64-75858).

Referring to FIG. 14, the air flow path 2 having a roof gradient is formed directly below a metal roof plate 1 such as a color iron plate as a solar heat collecting section. An opening is provided as an outside air intake 3 at the eaves or the like (there may be the back of a hut), and the other end is communicated with a ridge duct 4 as a heat collection box made of heat insulating material.

FIG. 15 shows the solar heat collecting section in more detail. The lower surface of an air flow path 2 having a roof gradient formed immediately below a metal roof plate 1 such as a color iron plate is provided with a heat insulating layer covered with glass wool or the like. 22 and a part of the roof was covered with glass 23. The glass 23 prevents the wind from hindering the heating of the metal roof panel 1 by solar heat by cooling when the external wind is strong.

A backflow prevention damper 6, a fan 7 and a flow path switching damper 8 are provided therein.
One of the outflow sides is provided with a handling box 5 that is opened to the outside by an exhaust duct 9 in the attic space, which is an attic space, and the inflow side of the backflow prevention damper of the handling box 5 communicates with the ridge duct 4. One of the outflow sides of the road switching damper 8 is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 is opened to an air circulation space 13 between the heat storage slab concrete 11 as a heat storage and heat radiation part and the floor panel 12, and a floor outlet 14 from the air circulation space 13 to the room is provided.

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 the backflow prevention damper 6 is connected to the circulation duct 19 which opens into the room by a ceiling or the like. The backflow prevention damper 6 is configured as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 19 side. In addition, a suction port 20 through which the circulation duct 19 opens.
If the room is provided on the second floor, it is preferable that the room be on the first floor where the floor panel 12 provided with the floor outlet 14 to the room has a blow-through structure to allow air to flow freely.

In the handling box 5, a hot water coil 15 is provided between the backflow prevention damper 6 and the fan 7, and the hot water coil 15 is circulated by a circulation pipe 16.

[0008] In this manner, 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, the heated air is collected in the ridge duct 4, enters the handling box 5 by the fan 7, flows down the falling duct 10 from the handling box 5, and flows through the heat storage soil concrete 11 and the floor panel 12. Enter the space 13. In this air circulation space 13, the heated air directly warms the floor under the floor via the floor panel 12, stores heat in the heat storage clay concrete 11, and is directly blown into the room as warm air from the floor outlet 14. The three types of heating action are performed.

On the other hand, the water fed from the hot water storage tank 17 through the circulation pipe 16 is heated by the hot water removal coil 15 and stored in the hot water storage tank 17 as hot water. The water is reheated by the hot water supply boiler 18 and supplied to various places from the hot water supply pipe.

[0010] By the way, in a high temperature season such as summer when heating is not required, it is necessary to discharge all the heated air heated by the roof panel 1 to the outside air and discard it. In this case, if the falling duct 10 which is one of the outflow sides is closed by the flow path switching damper 8 and the exhaust duct 9 which is the other one of the outflow sides is opened, the heated air is discharged from the handling box 5 through the exhaust duct. Discarded outside through 9. The heated air passes through the handling box 5 so that the hot water removal coil 1
Since the heating of No. 5 is performed, it can be ensured that hot water can be obtained by using solar heat even at a high temperature such as in summer.
