DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar system house using passive solar power, which collects daytime solar heat using air as a heat medium.

[0002]

2. Description of the Related Art In recent years, a solar system house capable of effectively utilizing air collected by sunlight without being limited to a direction has been proposed in Japanese Patent Application No. 61-311485 (Japanese Patent Application Laid-Open No. 63-165633). This is known from, for example, JP-A-62-234666 (JP-A-64-75858).

Referring to FIG. 11, the air flow path 2 having a roof gradient is formed immediately below a metal roof plate 1 such as a color iron plate as a solar heat collector provided on a roof.
One end of the air flow path 2 is at the tip of an eave or the like (it may be behind a shed)
The other end is opened as an outside air intake 3, and the other end is communicated with a ridge duct 4 as a heat collecting box made of a heat insulating material.

The lower surface of the air passage 2 is formed as a heat insulating layer 24 made of a panel board such as glass wool, and a part of the roof is covered with glass 23. The glass 23 prevents the wind from hindering the metal roof panel 1 from being heated by the solar heat when the external wind is strong.

A handling box 5 provided with an inflow-side damper 6, a heat collecting fan 7, and an outflow-side damper 8 is installed in a cabin 22 as an attic space, and one of the outflow sides of the outflow-side damper 8 is an exhaust duct. 9, open to the outdoors,
The other is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 opens into an air circulation space 13 between the heat storage soil concrete 11 and a floor panel 12 as a heat storage and heat radiation part, and a floor outlet 14 from the air circulation space 13 to the room is provided. .

[0006] One of the inflow sides of the inflow side damper 6 of the handling box 5 is communicated with the ridge duct 4, and the other is connected to a circulation duct 19 which opens to the room through a ceiling or the like. If the room provided with the inlet 20 through which the circulation duct 19 opens is the second floor, a floor outlet into the room is provided.
It is preferable that the room be on the first floor where the floor panel 12 provided with 14 has an atrium structure so that air can flow freely.

In the handling box 5, a hot water coil 15 is provided between the inflow side damper 6 and the heat collecting fan 7, and the hot water coil 15 is connected to a hot water tank 17 by a circulation pipe 16. Is equipped with a hot water supply boiler 18 for additional heating, and a hot water supply pipe leading to a bath, washroom, and kitchen
Connect 21.

[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, and the heated air rises along the roof gradient. Then, the heated air is collected in the ridge duct 4 and then enters the handling box 5 by the heat collecting fan 7, flows down from the handling box 5 in the falling duct 10, and flows between the heat storage soil concrete 11 and the floor panel 12. Air circulation space 13
Enter. In the air circulation space 13, heated air is supplied to the floor panel 12.
Heating directly under the floor via the slab, storing heat in the heat storage soil concrete 11, and directly blowing out the room as warm air from the floor outlet 14 perform three types of heating actions.

On the other hand, the water sent from the hot water storage tank 17 through the circulation pipe 16 is heated by the hot water collecting coil 15,
Hot water is stored in a hot water storage tank 17, and is reheated from here by a hot water supply boiler 18 for additional heating as needed, and is supplied to various places from a hot water supply pipe.

[0010] By the way, in a season such as summer when the temperature is high and 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 outflow side 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 9. Discarded outside through Since the hot air passes through the handling box 5 to heat the hot water removing coil 15, it is possible to ensure that hot water can be obtained by using solar heat even at high temperatures such as in summer.

[0011]

In such a solar system house, the ridge duct 4 as a heat collecting box made of the above-mentioned heat insulating material is installed in the space behind the hut. In some cases, a sufficient space cannot be secured, and in that case, it is difficult to install the ridge duct 4.

In addition, since the ridge duct 4 for collecting the air in the heat collecting section is installed on the indoor side of the heat insulating layer 24 of the roof, the heat of the collected air is radiated through the ridge duct 4 into the building. In winter, the temperature of the collected air drops, so that the amount of heat that can be effectively used is reduced. In summer, heat is radiated from the duct into the building, so that the building becomes hot.

[0013] From the above situation, in order to reduce the amount of heat released from the collected air flowing through the duct into the building, it is necessary to increase the thickness of the heat insulating material applied to the ridge duct. However, the cost of the heat insulating material is relatively high. Due to the increased construction time and the difficulty of disposal, it is rarely practiced to make the insulation sufficiently thick.

Further, as shown in FIG. 12, the connection between the air flow path 2 and the ridge duct 4 is performed by providing sleeve ducts 27 penetrating the row base plates 26 in each row between the rafters 25. The construction is cumbersome and troublesome, and there are also difficulties with waterproof measures.

An object of the present invention is to solve the inconvenience of the conventional example, and it is possible to install a heat collecting box even if the space behind the cabin cannot be sufficiently secured or the cabin back itself cannot be secured. There is no need to perform the sleeve work that penetrates the base plate for each row, so the work on the roof is very short, and since there are very few places to penetrate the base plate, reliable waterproofing It is easy to handle when penetrating the fire protection compartment, inspecting the inside of the duct after completion,
An object of the present invention is to provide a solar system house which is easy to perform maintenance and does not have a heat collecting box installed on the indoor side of a heat insulating layer of a roof, so that there is no risk of heat radiation into a building.

[0016]

In order to achieve the above object, according to the present invention, first, an air passage having a roof gradient is formed immediately below a roof plate, and one end of the air passage is provided as an outside air intake. Opening, the other end communicates with a heat collection box made of heat insulating material, a damper inside, a handling box provided with a heat collection fan is installed indoors, the inflow side of the handling box communicates with the heat collection box, and the outflow side In a solar system house, the tip of which is connected to a falling duct whose tip opens into the air flow space between the heat storage clay concrete and the floor panel, the heat collecting box is formed as a heat collecting duct having an air inlet on the side. The gist is that it was installed on the roof at the top of the road.

Secondly, the heat collecting duct is formed as a box having a rectangular cross section by a composite of a heat insulating material of a foamed resin and a steel plate, and the intake port is formed as a slit in its side plate.
In addition, the heat collecting duct is intended to be formed by connecting a large number of rectangular cross-section boxes.

According to the first aspect of the present invention, since the heat collection box is installed on the roof, it is possible to install the heat collection box even when the space behind the hut cannot be sufficiently secured or when there is no hut back itself. There is no risk of heat radiation into the building.
In addition, since the air inlet formed on the side can directly communicate with the air flow path directly below the metal roof plate, it is necessary to perform the sleeve construction that penetrates the row base plate of each row between rafters as is conventionally done. And the work on the roof can be completed in a short time. Moreover, in relation to the handling box, the number of ducts penetrating through the field board is extremely small at one place, so that the reliability in waterproofness is high.

According to the second aspect of the present invention, in addition to the above-described functions, the heat collecting box is made of a composite of a heat insulating material made of foamed resin and a steel plate, so that safety against fire is taken into consideration. Also, since the slit formed in the side plate is used as an intake port, it can be easily formed.

According to the third aspect of the present invention, since the heat collecting duct is formed by connecting a large number of rectangular cross-section boxes, even a long heat collecting duct can be easily and safely formed on the roof. Can be.
