Abstract

PURPOSE:To improve the utilization of heat collection by installing a heat collecting box, the inside of which is surrounded by a heat-insulating layer, to the ridge section of a roof and making the heat collecting box and heat- accumulating and heat-dissipating sections communicate with each other through a duct while interposing a box, into which a blower is incorporated. CONSTITUTION:A colored iron plate 6 and glass plates 10 of a roof 5 heated by solar rays warm air in an air flow path 7 in a solar heat collecting section A. The warmed air rises along a gradient and enters a heat collecting box 21 as a ridge duct while the outside air enters anew into the air flow path 7 from an outside-air intake 8 and is warmed and rises. Heated air generated in the solar heat collecting section A in the roof 5 is collected by the heat collecting box 21, and sent into the air flowing space 33 of a floor 30 through a duct 23 by a blower 25. Warm air in the air flowing space 33 is given moisture by a humidifying pan 40, and blown off into an indoor section C from a warm-air blow-off port 34, thus warm-air heating is obtained. Accordingly, air collecting heat from solar rays can be utilized effectively.

Description

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 and heat radiating section B are communicated with each other by a duct 23 which is a vertical duct, and a space 47 for installing the blower 25 is secured 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 suction force of the blower 25 directly acts on the air flow path 7 and the flow in the air flow path 7 becomes faster, so that the solar heat collection is performed. There is a possibility that sufficient warm air cannot be obtained in the part A.

Further, since the roof plate has a weak power to warm the air in the air passage 7 when sufficient solar radiation is not obtained, relatively cold 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.

An object of the present invention is to eliminate the disadvantages of the conventional example and to provide a solar system house capable of effectively utilizing the air collected by sunlight.

[0014]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a solar heat collecting portion, a concrete slab, and a floor panel, in which a space for forming an air passage having a roof slope is secured immediately below a roof plate. An air circulation space is formed between the air circulation space and a heat storage and heat dissipation portion provided with an air outlet to the room are communicated with each other through a duct, and a box with a built-in blower is disposed in the middle of the duct. In the system house, a heat collecting box whose inside is surrounded by a heat insulating layer is provided in the roof ridge portion, the upper end of the air passage having the roof slope is communicated with the heat collecting box, and the heat collecting box and the heat storage and The gist of the invention is that the heat radiating portion is communicated with a duct through the box with the built-in blower.

[0015]

According to the present invention, in the solar heat collecting section, when the roof plate heated by sunlight heats the air in the air flow path, the warmed air naturally rises along the gradient, and first, the collected air is collected. Stored in the heat box. Then, new outside air enters the air flow path from the lower end, is warmed similarly, and rises along the roof slope. By driving the blower at a stage where the warmed air is stored in the heat collecting box to some extent, only the warm air can be blown into the air circulation space of the floor through the duct by the blower.

Further, the blower gradually sucks the air accumulated in the heat collecting box and sends it into the air circulation space of the floor. Due to the heat collecting box, the suction force of the blower is directly applied to the roof plate. It is also possible to prevent the flow velocity from being unnecessarily increased by acting on the air flow path immediately below.

[0017]

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 part A, and a space is secured immediately below a color iron plate 6 as a roof plate which is a roofing material to form an air passage 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, and 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 styrofoam 9c is attached to the lower surface, 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.

The fact that the metal roof plate is further covered with the glass plate 10 has the 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.

According to the present invention, a heat insulating layer 9 is provided on the inside of the ridge of the roof 5.
The ridge duct surrounded by is formed as the heat collecting box 21. Since this heat collecting box 21 is a ridge duct, it is long in the ridge direction, and the upper end of the air flow path 7 of the roof 5 communicates with it.

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

Reference numeral 23 in the drawing is a vertical duct that connects the ridge duct 21 and an air circulation space 33 of a floor 30 described later, and a box 46 is provided in the middle of the duct 23. The box 46 is provided with a gravity damper 24 and a blower 25 for preventing backflow, and a flow path switching damper 26 is further attached to the end of the damper.
The part branched from 26 is opened to the outside to form an exhaust duct 27 for the case where only hot water heat exchange is performed in summer.

As the blower 25, a fan coil unit provided as an accessory to the liquid heat exchanger 28 is used. However, when the blower 25 is not a unit component but an independent unit, heat is generated separately from the blower 25. An exchange 28 is provided.

The floor 30 is a portion which becomes a 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 can be considered. 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 give directionality to 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 has 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 through the color iron plate 6, and the glass plate 10 rises along the gradient and enters the heat collecting box 21 which is a ridge duct. 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 the air distribution space 33 of the floor 30 is blown by the blower 25 through the duct 23.
Sent to.

The warm air sent into the air circulation space 33 is
Humidification tray 40 can be used to add appropriate moisture, and a hot air outlet
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 heats the floor by directly heating the floor through 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 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.
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 and at night, 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 duct 23, only produces hot water in the heat exchanger 28, and is discharged from the exhaust duct 27 to the outside.

Therefore, it is used only as a hot water supply system in the summer, but when the heat more than necessary is given to the heat exchanger 28, the damper 22 of the heat collecting box 21 is opened, and the blower is used.
Stopping 25 is done.

[0043]

As described above, in the solar system house of the present invention, the solar heat collecting part of the roof is combined with the heat storing and radiating part of the floor so that the warm air directly warms the floor surface. In the case of performing three types of heating operations, that is, heat is stored in the heat storage body and is directly heated by being blown out into the room from the hot air outlet, heat is collected by sunlight by arranging a heat collection box. It is possible to effectively utilize the generated air.
