Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solar system house that utilizes solar energy through air.

[Conventional technology and its problems]

It has been practiced for a long time to create a large opening on the south side of a house to let in a large amount of sunlight in winter, and to leave part of it open in summer for ventilation.
Taking this a step further, some people create a sunroom outside the living room and use it as a greenhouse to bring warmed air into the living room.

In that case, only the air stores heat,
For example, as shown in Figure 10, concrete outer wall 1
If the outer wall 1 is covered with glass 2 or the like and the space between the two is used as an air circulation path 4 to the indoor room 3, the outer wall 1 itself acts as a heat storage body, and a stable supply of heat can be obtained.

However, all of these methods are limited to controlling relatively south-facing indoor spaces, and have the disadvantage that there is a large temperature difference between them and the north-facing indoor spaces.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
The objective is to provide a solar system house that can effectively utilize air heated by sunlight, regardless of orientation.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention secures a space directly under the colored iron plate serving as a roof plate to form an air flow path with a roof slope, and the solar heat collecting section forms an air flow path with a roof slope on the underside of the eaves. The lower end is opened to serve as an outside air intake, and the lower surface of the air flow path is made of a heat insulating layer made of a heat insulating material such as glass wool.
A ridge duct surrounded by a heat insulating layer on the inside of the ridge of the roof is used as a heat collection box, and the upper end of the air flow path of the roof of the solar heat collection section is communicated with the ridge duct, thereby creating an air circulation space between the concrete slab and the floor panel. form,
An air outlet from the air circulation space to the room is provided to constitute a heat storage and heat dissipation section, and in the middle of a vertical duct that communicates the ridge duct with the air circulation space of the heat storage and heat dissipation section,
The gist is that a damper, a blower, and a flow path switching damper are installed to prevent backflow, and that a portion branching off from the flow path switching damper is opened at its tip to the outside.

[Effect]

According to the present invention, in the solar heat collecting section, when the roof plate heated by sunlight warms the air in the air flow path,
This warmed air rises along the slope, enters the ridge duct from the upper end of the air flow, and is collected there.

Then, new outside air enters the air flow path from the lower end, is heated in the same way, and rises along the roof slope.

During winter, the flow path switching damper blocks the branch side that opens to the outside, and the heated air collected in the ridge duct flows down inside the vertical duct using a blower and enters the heat storage and heat radiation section under the floor.

In the heat storage and heat dissipation section, hot air sent from a duct passing through an air flow path directly heats the floor surface, is stored in a heat storage body such as a concrete slab, and is blown into the room from a hot air outlet. It works in three ways, including direct heating.

At this time, warm outside air is constantly injected into the room under pressure, which prevents cold outside air from entering through gaps in other windows, walls, etc.

After the heat has been collected during the day, at night, the air under the roof cools, condenses, and tends to flow downward in the opposite direction from when the heat was collected. In that case, if you stop the blower and close the damper to prevent backflow, the heat collection circuit will be closed, so warm air from inside the room or under the floor will not escape to the outside.

In addition, when heating is not required at all, such as in the summer, the flow path switching damper allows the branch side that opens to the outside to communicate, and blocks the side that communicates with the heat storage and heat dissipation section under the floor, which allows the roof to absorb solar heat. The heated air generated in the heat collecting section is discharged outdoors without unnecessary heating.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figure 1 shows one of the solar system houses of the present invention.
It is a longitudinal sectional front view showing an example, and 5 in the figure shows a roof.

The roof 5 serves as a solar heat collecting part A, and it secures a space directly below the colored iron plate 6 as a roofing material to form an air passage 7 with a roof slope, and also forms an air flow path 7 with a roof slope, etc. The lower end of this air passage 7 is opened to form an outside air intake port 8.

The lower surface of the air flow path 7 is constructed as a heat insulating layer 9 made of a heat insulating material such as glass wool.
0 was set.

Note that various specific examples of the structure of the roof 5 having such an air flow path 7 can be considered.

For example, as shown in FIG. 3, a collar iron plate 6 may be supported on a glass wool board 9a via a V-shaped deck board 11, or the upper surface of a control panel 12 may be covered with aluminum foil 13 as shown in FIG. A styrofoam 9c is pasted, glass wool 9b is laid on the lower surface, and the colored iron plate 6 is supported on the control panel 12 with a wooden square lumber 14 at a distance, and a glass plate 16 is further placed above the iron plate 6 via a stylus 15. It may also be provided.

Furthermore, as shown in FIG. 5, an asbestos cement extrusion molded board 17 can be used as a roof plate, a styroform 9c can be pasted on the lower surface, and the upper surface can be covered with a waterproof sheet 18, or a control panel 12 can be used as shown in FIG.
Glass wool 9b on top and aluminum foil 13 on top
It is possible to form a heat insulating layer consisting of a glass wool board 9a on which a glass wool board 9a is attached, place a corrugated plate 19 made of an aluminum profile whose upper surface is covered with a transparent film 19a, and further provide a glass plate 16 made of tempered glass above it. As shown in FIG. 7, it is also possible to stack a glass wool board 9a on top of the control panel 12, place large corrugated plates 20 such as zinc plates on top of each other, and cover the top with a glass plate 16.

The reason why the metal roof panels are covered with a glass panel is to prevent the roof panels from being cooled by wind when they are heated by sunlight. The rate of temperature rise will improve.

A ridge duct 21 whose inside is surrounded by a heat insulating layer 9 is formed in the ridge part of the roof 5, and the upper end of the air passage 7 of the roof 5 is communicated with this. In this way, the ridge duct 21 becomes a heat collection box from the solar heat collection part A, and the communication port to the outside is equipped with a damper that opens at a certain temperature or higher using a shape memory alloy for exhaust when heat is not collected. 22 was installed.

In the figure, 23 is a vertical duct that communicates the ridge duct 21 with the air circulation space 33 of the floor 30, which will be described later. Install the flow path switching damper 26 first, and then
The end of the branched portion from 6 is opened to the outside, and is used as an exhaust duct 27 for when only hot water exchange is performed in the summer. Note that the blower 25 is a fan coil unit that is provided as an accessory to the liquid heat exchanger 28, but if it is an independent unit rather than a unit part, the blower 25 may be used as a fan coil unit.
A heat exchanger 28 is provided separately from the heat exchanger 5.

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

As with the roof 5, various specific structures for the floor 30 can be considered, and as an example, as shown in FIG. 3
7 or use an asbestos cement extrusion plate 38 as shown in FIG.

By the way, the concrete of the concrete slab 31 or the asbestos cement extruded plate 38 shown in FIG. do.

Note that which areas are considered unnecessary depends on how the heating is used. For example, if it is desired to also warm the first floor in FIG. 1, the lower surface of the concrete slab 31 may not be insulated, but the heat can be radiated from the ceiling 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 pan placed within this air circulation space 33, facing 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 through 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 boiler 43 and a three-way valve 44 in the middle. It is connected to a hot water supply pipe 45 that connects to a bath, washroom, and kitchen.

Next, how to use it will be explained.

When trying to actively utilize solar heat in winter, etc., the damper 22 of the ridge duct 21 is closed, and the switching damper 26 is closed to the exhaust duct 2.
Blocking the 7th side.

When there is sunlight during the day, the colored iron plate 6 and the glass plate 10 of the roof 5 are heated, and the colored iron plate 6
The air in the air flow path 7 immediately below is also warmed through the air, rises along the slope, and enters the ridge duct 21 as a heat collection box. At the same time, outside air intake 8
Fresh air from the outside enters the air flow path 7 and is heated in the same way.

In this way, the heated air generated in the solar heat collection section A on the roof 5 is collected into the ridge duct 21 and then sent by the blower 25 through the duct 23 into the air circulation space 33 on the floor 30.

The hot air sent into the air circulation space 33 is appropriately moistened by the heating plate 40 and is blown out from the hot air outlet 34 into the room C to provide hot air heating.
Since warm air is always supplied to the room C by the blower 25, although the air in the room C may escape through gaps between doors, windows, and walls, cold air from outside never enters.

Furthermore, the warm air that has entered the air circulation space 33 is
Floor heating that directly heats the floor surface via the floor panel 32 is also performed. Furthermore, the concrete slab 31 is heated,
It also stores heat here.

On the other hand, in the middle of the duct 23, there is a 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 pipe 41b, and then directly or from the auxiliary hot water boiler 4.
The hot water is reheated at step 3 and supplied to various locations from the hot water supply pipe 43.

By the way, the duct 2 that supplies heat to the heat exchanger 28
Looking at the relationship between the warm air in the chamber 3 and the hot water that is supplied with heat from the heat exchanger 28, as the hot air reaches its high temperature peak, the heat exchanger 28 absorbs more heat and produces hot water. Due to the presence of the heat exchanger 28, the energy of the hot air that passes through it and is used for heating is not affected much by the position of solar radiation throughout the day and is averaged out, resulting in stable heating. That is, without the heat exchanger 28, depending on the position of the sun, unnecessarily heated air may be sent into the room, making temperature control difficult.

After the daytime heat collection is finished, at night, etc., the air under the roof 5 is cooled down, condenses, and tends to flow downward in the opposite direction to that during heat collection. In that case,
The operation of the blower 25 is stopped, and the gravity damper 2 is
4 will automatically close and close the heat collection system circuit, so
The warm air in room C and under the floor 30 does not escape outside. Rather, under the floor 30, heat radiation from the concrete slab 31 as a heat storage body continues the floor heating.

When heating is not required at all, such as in summer, the switching damper 26 closes the floor 30 side of the duct 23 and opens the exhaust duct 27 side. As a result, the heated air generated in the solar heat collection part A of the roof 5 enters the duct 23, only produces hot water in the heat exchanger 28, and is then discharged to the outdoors through the exhaust duct 27.

Therefore, in the summer, it is used only as a hot water supply system, but if more heat 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.

〔Effect of the invention〕

As described above, in the solar system house of the present invention, the roof panel heated by sunlight warms the outside air that enters the air flow path, and this warmed air rises along the roof slope, so the outside air is heated. Even without actively drawing in air with a fan or the like, the rising action along the roof slope allows outside air to be drawn in efficiently and heated.

Then, this heated air flows down inside the duct by the blower and enters the heat storage and heat radiation section below the floor surface. By directing the air that collects heat from sunlight on the roof to below the floor, efficient heating is possible regardless of direction, and warm air is supplied indoors from below the floor, reducing the draft load and increasing heating efficiency. This will improve the results.

In addition, since the blower only serves to send the hot air rising on the slope of the roof downward, it can be small, and the equipment costs and running costs for the entire system are low.
