Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to 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.

In this case, heat is stored only in the air, but for example, as shown in FIG. 10, the outside of the concrete outer wall 1 is covered with glass 2 or the like, and an air circulation path 4 to the room 3 is provided between them. For example, the outer wall 1 itself acts as a heat storage body and a stable heat supply can be obtained.

However, all of these methods are limited to the control of the indoor space facing the south, and there is a drawback that a large temperature difference occurs between the indoor space facing the north.

Therefore, there has been proposed a solar system house which is not limited to the orientation shown in FIG. 11 and can utilize the air collected by sunlight.

In this structure, the roof 5 is used as a solar heat collecting section A, and an air flow path 7 having a roof slope is formed by securing a space directly below a color iron plate 6 as a roof plate, and also on the lower surface of the eaves. The lower end of this air flow path is opened to serve as an outside air intake port 8.

On the other hand, the heat storage and heat radiating portion B which is the floor 30 is an air circulation space between the concrete slab 31 and the floor panel 32.
33 is formed, and the air circulation space 33 has an outlet 34 to the room C.

The solar heat collecting section A and the heat storage / radiation section B are communicated with each other by a duct 23 which is a vertical duct, and a blower 25 is arranged at the upper end of the duct 23.

When the blower 25 is driven in this way, in the solar heat collecting section A, the air entering the air passage 7 from the outside air intake port 8 is warmed by the roof plate heated by the sunlight, and the warmed air is heated. Rises along the slope, flows down from the upper end of the air flow path in the vertical duct 23, and enters the heat storage and heat dissipation part B under the floor.

In the heat storage / radiation section B, the hot air sent from the duct 23 directly heats the floor surface, the heat is stored in a heat storage body such as the concrete slab 31, and the hot air outlet is provided.
It is blown from 34 into the room C and directly heats the room.

[0011]

However, in the solar system house shown in FIG. 11, the blower 25 has to be provided with a space 47 for installing the blower 25 as a small room communicating with the duct by enclosing it with a heat insulating plate material. Construction is troublesome.

Further, if unnecessary exhaust is directly performed from the space 47 to the outside, the exhaust location is limited to the top of the roof where the space 47 is located.

If the space 47 directly communicates with the air flow passage 7 having a roof slope, the suction force of the blower 25 acts on the air flow passage 7 so that the flow in the air flow passage 7 is fast. Therefore, there is a possibility that sufficient warm air cannot be obtained in the solar heat collecting part A.

In particular, at a time when sufficient solar radiation is not obtained, such as in the morning, since the roof plate has a weak power to warm the air in the air passage 7, relatively cool air is taken into the heat storage and heat radiating portion B under the floor. , There is also the possibility that it will have the opposite effect.

The object of the present invention is to eliminate the disadvantages of the conventional example and to construct a solar system house in which the air collected by sunlight can be effectively used. By installing a damper on this, as a handling box for controlling, and as a connecting and collecting member at the end of the duct, intake and delivery of warmed air, and an exhaust duct when unnecessary is centered around this handling box. It only needs to be connected, it can be integrated, and the factory-manufactured handling box can be installed on site to streamline the construction. In addition, since there is a ridge duct as a heat collection box, warmed air can be stored here. Due to the accumulation, the suction force of the blower directly acts on the air flow path directly below the roof plate and it cannot be heated sufficiently. Both object of the present invention is to provide a solar system house that can be prevented.

[0016]

In order to achieve the above-mentioned object, the present invention has a solar heat collecting portion in which an air passage having a roof slope is formed by securing a space directly under a roof plate, a concrete slab and a floor panel. In the solar system house, in which an air circulation space is formed between the air circulation space and the heat storage and heat dissipation portion is connected to the room by a duct with a blower interposed, inside the roof ridge portion. A ridge duct surrounded by a heat insulating layer is provided as a heat collecting box, the upper end of the air flow path of the roof of the solar heat collecting section is communicated with this, and a blower is installed in the box, and more than the blower of this box. Connect the exhaust duct to the outside on the leeward side,
Further, the box has a damper for preventing backflow between the connection port of the communication duct to the ridge duct and the blower, and the connection port of the exhaust duct and the connection of the communication duct to the heat storage and heat dissipation part. A flow path switching damper that selectively closes one of these connection ports is installed between the port and the blower, and a heat exchanger for hot water supply is also installed in this box on the windward side of the flow path switching damper. The gist is that it is provided and configured as a handling box.

[0017]

According to the present invention, the box in which the blower is installed can be handled as an integrated control device by previously mounting a damper for preventing backflow and a flow path switching damper as a handling box. .
It is sufficient to connect each duct such as a communication duct to the ridge duct, a communication duct to the heat storage / radiation unit, and an exhaust duct to the handling box, and the design and construction become a simple pattern.

Also, by installing a heat exchanger for hot water supply in this handling box, the installation place can be integrated.

In addition to this, the blower gradually sucks the air accumulated in the ridge duct, which is a heat collecting box, and sends it into the air circulation space on the floor. It is also possible to prevent the suction force from directly acting on the air flow path directly below the roof plate to unnecessarily increase the flow velocity.

[0020]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows a solar system house 1 according to the present invention.
FIG. 5 is a vertical sectional front view showing an embodiment, in which reference numeral 5 indicates a roof.

The roof 5 serves as a solar heat collecting portion A, and a space is secured immediately below a colored iron plate 6 as a roof plate which is a roofing material to form an air flow path 7 having a roof slope, and The lower end of the air flow path 7 is opened on the lower surface of the eaves and used as an outside air intake 8.

The lower surface of the air flow path 7 is formed as a heat insulating layer 9 made of a heat insulating material such as glass wool. In this embodiment, a glass plate 10 is provided above the colored iron plate 6 at the top of the roof 5. Various concrete examples of the structure of the roof 5 having such an air flow path 7 are possible.

For example, as shown in FIG. 3, the color iron plate 6 is supported on the glass wool board 9a through the V-shaped deck board 11, or the upper surface of the control panel 12 is an aluminum foil 13 as shown in FIG. Stick the Styrofoam 9c covered with, and lay glass wool 9b on the lower surface,
It is also possible to support wooden panels 14 on the control panel 12 with a space therebetween, and further to provide a glass plate 16 above the iron plate 6 via a roof bar 15.

As shown in FIG. 5, the asbestos-cement extruded plate 17 is used as a roof slab, the lower surface is covered with the styrofoam 9c, and the upper surface is covered with the waterproof sheet 18,
As shown in FIG. 6, glass wool 9b is placed on the control panel 12.
And glass wool board 9a with aluminum foil 13 on top
Form a heat insulating layer consisting of a transparent film on top of it
A corrugated plate 19 made of aluminum material covered with 19a is placed, and a glass plate 16 of tempered glass is further provided above the corrugated plate 19, and FIG.
Glass wool board 9a on control panel 12 as shown in
Alternatively, a large corrugated plate 20 such as a zinc plate may be placed on top of it, and the upper side thereof may be covered with a glass plate 16.

By covering the metal roof plate with the glass plate 10, there is an effect of preventing the roof plate from being cooled by wind or the like when it is heated by solar radiation. This improves the rate of temperature rise of the roof plate.

In the present invention, the inside of the ridge portion of the roof 5 is covered with the heat insulation layer 9
The ridge duct 21 as a heat collection box surrounded by is formed.
The upper end of the air flow path 7 of the roof 5 is communicated with this ridge duct 21.

Further, the ridge duct 21 is provided with a communication port to the outside, and a damper 22 which is opened at a temperature equal to or higher than a certain temperature by using a shape memory alloy for exhaust when heat is not collected is attached to the communication port.

In the figure, 23a and 23b are the ridge duct 21 and the floor 30 described later.
This is a communication duct that communicates with the air circulation space 33, and a handling box 46 is provided between the ducts 23a and 23b. The blower 25 is installed inside the handling box 46. An exhaust duct 27 to the outside is connected to the leeward side of the blower 25, and the handling box 46 is further provided.
A gravity damper 24 for preventing backflow is provided between the blower 25 and the connection port of the communication duct 23a to the ridge duct 21.

Further, between the connection port of the exhaust duct 27 and the connection port of the communication duct 23b to the heat storage and heat dissipation part and the blower 25, a flow path switching damper for selectively closing one of these connection ports. I installed 26.

The blower 25 uses a fan coil unit provided as an accessory to the liquid heat exchanger 28. However, if it is not a unit component but an independent unit, a heat generator separate from the blower 25 is used. An exchange 28 is provided.

The floor 30 is a portion which becomes the heat storage and heat radiation portion B, and is an air circulation space between the concrete slab 31 and the floor panel 32.
33 is formed, and the air circulation space 33 has an outlet 34 to the room C.

Similar to the roof 5, various concrete structures of the floor 30 are conceivable. For example, as shown in FIG. 8, a concrete panel slab 31 is laid on the concrete slab 31 via joists 35, and the floor is placed thereon. A finishing sheet 37 may be attached or an asbestos-cement extruded plate 38 may be used as shown in FIG.

By the way, the concrete of the concrete slab 31 or the asbestos-cement extruded plate 38 of FIG. 9 is used as a heat storage body, and a heat insulating layer 39 such as styrofoam is provided on an unnecessary surface in order to direct the heat radiation. Form.

It should be noted that which of the unnecessary surfaces differs depending on how the heating is used. For example, in FIG. 1, if it is desired to heat the first floor as well, the lower surface of the concrete slab 31 is not insulated,
You may make it possible to obtain the heat radiation from the ceiling surface of the first floor.

The lower end of the duct 23 communicates with the air circulation space 33 of the floor 30. Reference numeral 40 in the figure denotes a humidifying tray placed in the air circulation space 33 so as to face the lower end opening of the duct 23.

As shown in FIG. 2, the heat exchanger 28 is connected to an open hot water storage tank 42 by a circulation line with a water injection pipe 41a and a water supply pipe 41b, and the hot water storage tank 42 is connected to an auxiliary hot water supply boiler 43 and a three-way valve 44. Is connected to the hot water supply pipe 45 that connects to the bath, washroom, and kitchen.

Next, the usage will be described. When actively using solar heat in winter, etc., the building duct
The damper 22 of 21 is closed, and the switching damper 26 blocks the duct 27 side for exhaust.

When there is sunlight during the day, the colored iron plate 6 of the roof 5
The glass plate 10 is heated, and the air in the air flow path 7 directly below the glass plate 10 is also heated via the color iron plate 6, and rises along the gradient to enter the ridge duct 21 which is a heat collecting box. At the same time, fresh air newly enters the air flow path 7 from the fresh air intake port 8 and is sequentially warmed similarly.

In this way, the heated air generated in the solar heat collecting section A of the roof 5 is collected in the heat collecting box 21, and then enters the handling box 46 through the communication duct 23a, and the blower 25 connects the communication duct. It is sent to the air circulation space 33 of the floor 30 via 23b.

The warm air sent into the air circulation space 33 is
The heating dish 40 can be appropriately humidified and the hot air outlet can be used.
The air is blown from 34 to the room C, and it becomes warm air heating. Since warm air is constantly supplied to the room C by the blower 25, the air in the room C may come out through the gaps between the doors, the windows, and the walls, but the cold air outside does not enter.

The warm air entering the air circulation space 33 also performs floor heating for directly heating the floor surface via the floor panel 32. It also warms the concrete slab 31 and stores heat here.

On the other hand, in the middle of the duct 23, the heat exchanger 28
The water sent from the water injection pipe 41a is heated and stored as hot water in the hot water storage tank 42 via the water supply pipe 41b, and is further heated directly from here or by the auxiliary hot water boiler 43 to supply hot water piping 45.
Is supplied to each place.

By the way, a duct for applying heat to the heat exchanger 28
Looking at the relationship between the hot air inside 23 and the hot water that gives heat from the heat exchanger 28, as the hot air reaches a high temperature peak, the heat exchanger 28 produces more hot water and creates hot water. Since the heat exchanger 28 is provided, the energy of the warm air that passes through the heat exchanger 28 and is used for heating is averaged irrespective of the position of solar radiation during the day, and stable heating is obtained. That is, without this heat exchanger 28, air heated more than necessary may be sent into the room depending on the position of the sun, and temperature control is troublesome.

At the end of daytime heat collection, the roof 5
On the contrary, the lower air is cooled, condenses, and becomes a downward flow and tries to flow in the direction opposite to that at the time of heat collection. In that case, blower 25
The operation is stopped and the gravity damper 24 is automatically closed to close the circuit of the heat collecting system, so that the warm air under the room C or the floor 30 does not escape to the outside. Rather, under the floor 30, heat radiation from the concrete slab 31 as a heat storage body continues floor heating.

When heating is not required at all in summer, the floor 30 side of the duct 23 is closed by the switching damper 26 and the exhaust duct is used.
Open side 27. As a result, the heated air generated in the solar heat collecting portion A of the roof 5 enters the handling box 46 through the communication duct 23a, and only heat is produced in the heat exchanger 28. Discarded outdoors via duct 27.

Therefore, although it is used only as a hot water supply system in the summer, when the heat more than necessary is given to the heat exchanger 28, the damper 22 of the ridge duct 21 is opened and the blower 25 is stopped.
