The solar heat collector installed on the roof heats the heat medium, and the heat medium is circulated between the heat collector and the underfloor to heat the heat storage concrete.

[0003]

The solar house is heated by solar heat. However, no matter how much heating is performed, the room temperature does not rise because the heat radiated to the outside is large. It is greatly affected by the heat insulation of.

The present invention has been made in view of the above, and an object thereof is to provide a high-performance solar house by combining an excellent heat storage material and an effective heat retaining structure.

Provide a house.

[0006] When the heat storage material is formed of granular stones, gaps are formed between the grains, and the heat storage performance is lower than that of the heat storage concrete, but the reduced amount can be almost compensated by filling sand between the grains. And the heat storage material of the present invention, at the time of construction,
Since stone, sand, and charcoal can be put under the floor in this order, the construction cost can be reduced compared to heat storage concrete, and since no water is used for construction, the first and second floors of the wooden house are also on the first floor. A heat storage material similar to can be applied. On the other hand, the roofing material has a layer of heat insulating material preliminarily formed in the hollow part, so there is no need to provide a separate heat insulating material on site,

Provided is a solar house which is provided with an indoor heat insulation means.

[0008] In winter, the time period during which the sunlight shines through the opening and raises the room temperature varies depending on geographical conditions and location conditions. If, for example, it is about 6 hours a day, a timer is used as a guide. If set, the curtain will automatically close at the timing when the room temperature starts to fall even if the user goes out with the curtain open, and the heat radiation from the opening is reduced. And if the weather gets worse before the set time of the timer and the outside gets dark due to snow or rain, the light sensor detects the change of the light and the curtain is closed from the opening even before the set time. Suppresses unnecessary heat dissipation. Therefore, by combining this indoor heat retention means and a heat storage material, it is possible to improve the performance of the solar house.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION A solar house 1 includes a heat collector 3 installed on a roof 2 and a heat storage material 5 provided in a space 4 under a floor.
A heat dissipation pipe 6, a floor heating auxiliary boiler 7, a hot water storage tank 8, a hot water supply auxiliary boiler 9, and a pump unit 10 for circulating a heat medium (antifreeze in this example). Configure a heating system.

[0012]

[Heating System] First, the details of the heating system of the present invention will be described with reference to the circuit diagram of FIG. The path through which the heat medium circulates is the solar heat heating path X that circulates the heat collector 3 and the heat storage material 5 (correctly the heat radiation pipe 6, but for convenience sake is referred to as “heat storage material”), the floor heating auxiliary boiler 7, and the like. It is divided into an auxiliary heating path Y that circulates the heat storage material 5 and a hot water supply path Z that circulates through the heat collector 3 and the heat exchanger 11 in the hot water storage tank 8. However, the solar heating path X is designed to pass through the heat exchanger 11 of the hot water storage tank 8 while returning from the heat storage material 5 to the heat collector 3.

Three pumps P1 to P3 are provided in the entire path,
Five solenoid valves V1 to V5 and three temperature sensors S1 to
S3 is provided, and all these elements are connected to a control device (not shown) to switch and control the three paths X, Y, Z. In the circuit diagram, reference numeral 12 is a liquid storage tank that stores the heat medium, and stores the heat medium of the heat collector 3 in the liquid storage tank 12 when the heating system is stopped.

[Heat Storage Material] Next, the heat storage material 5 will be described. Heat storage material 5
As shown in FIGS. 3 (a) and 3 (b), is approximately 2 / of the space 4 from the back surface of the floor material 14 to the heat insulating material 140 under the floor.
Granular stones 5a are spread to a height of 3, sand 5b is filled between the grains of the stones 5a, and charcoal 5c is spread on the mixture of the stones 5a and sand 5b. And sand 5b. It should be noted that FIGS. 3A and 3B are schematic diagrams, and needless to say, the intergrains of the actual stone 5a are denser.

As the stone 5a, crushed stone or gravel is used. Alternatively, as a granular heat storage main material instead of the stone 5a, a waste material of glass, ceramics, or gypsum may be crushed into particles. Examples of the glass product include a glass bottle and a window glass for a vehicle, but other glass products may be used. Examples of the ceramic products include ceramic tableware, vases, ornaments, tiles, and roof tiles, but of course, other ceramic products may be used. The gypsum exemplifies a used gypsum mold used when manufacturing a ceramic product, but other gypsum may of course be used. If such a waste material is used as a substitute for the stone 5a, it can contribute to solving the problem of waste disposal, which is currently becoming a social problem. On the other hand, although the charcoal 5c mainly uses charcoal, it may be bamboo charcoal made of bamboo.

As a construction procedure, a heat radiation pipe 6 is installed at a predetermined position in the space 4 under the floor, and a joist 15 (floor material 1
Stones 5a, sand 5b, and charcoal 5c are placed in the space 4 in this order before the flooring 14 is stretched on the cross bar supporting 4). As is clear from this procedure, since no water is required for construction of the heat storage material 5, it is possible to easily install the heat storage material 5 under the floor above the second floor of the wooden house, and thus under the floor above the second floor above the wooden house. The same floor heating as the first floor can be applied.

Since the heat storage material 5 of the present invention is constructed as described above, when the heat medium heated by the solar heat is passed through the heat radiation pipe 6, the heat heats the stones 5a and the sand 5b, and the upper layer. The floor material 14 is warmed through the charcoal 5c and the room temperature rises. Further, since the heat storage material 5 stores the heat of the heat medium, when the solar heat cannot be obtained, the stored heat is released to maintain the room temperature. Then, when the temperature of the heat storage material 5 decreases, the circuit switches from the solar heating route X to the auxiliary heating route Y as described above, and the floor heating auxiliary boiler 7 heats the heat medium to continue floor heating.

Although the heat storage material 5 of the present invention is applied to the floor of the first floor in the embodiment, the conventional heat storage material made of heat storage concrete is used for the first floor of the building, and the heat storage material of the present invention is used for the second floor and above. The heat storage material 5 may be used in combination as appropriate.

Further, the heat storage material 5 of the present invention is composed of upper and lower two layers such as a lower layer of a mixture of stones 5a and sand 5b and an upper layer of charcoal 5c, and mainly stores heat in the lower layer. However, by utilizing this feature, it is possible to develop the following heating system. That is, as shown in FIG.
A heat radiating pipe 60 having the same structure as the heat radiating pipe 6 passing through the layer of stones 5a and sand 5b is also passed through the layer of charcoal 5c.
The floor heating auxiliary boiler 7 is connected to 0, and thus the auxiliary heating path Y is constituted by the floor heating auxiliary boiler 7 and a heat radiating pipe 60 passing through a layer of charcoal 5c.

The heating system thus constructed can effectively use solar heat as compared with the conventional case, and is effective in reducing fuel consumption for 24-hour heating. In other words, the heating system described above discharges the solar heat stored in the daytime heat storage material 5 at night and performs heating for 24 hours, but since the heat storage amount of the heat storage material 5 is limited, it is difficult to cool down on a day. In the morning, the amount of heat of the heat storage material 5 is insufficient, and the floor heating auxiliary boiler 7 is operated to compensate for the insufficient amount.

However, conventionally, the heat medium warmed by the floor heating auxiliary boiler 7 passes through the same radiating pipe 6 as the solar heating route X, so that the floor heating auxiliary boiler 7 warms the heat storage material 5. Since floor heating is performed, the system is such that the temperature of the heat storage material 5 does not drop below a certain level. This means that a part of the capacity of the heat storage material 5 is always in the heat storage state and the heat storage capacity of the solar heat is reduced accordingly.

On the other hand, in the above heating system, the heat medium heated by the floor heating auxiliary boiler 7 is the carbon 5 close to the floor material 14.
Since it passes through the layer c, most of the energy is efficiently used for floor heating, and during that time, heat is continuously radiated from the layers of stones 5a and sand 5b, and the heat storage capacity increases. Therefore, when the solar heating route X starts to operate, a large amount of solar heat is stored in the layers of the stone 5a and the sand 5b. In addition, solar heating route X
If the circuit is set so that the heat medium of the heat collector 3 is guided to both the heat radiating pipe 6 and the heat radiating pipe 60 at the beginning of the operation of, the startup time of heating by solar heat can be greatly shortened. Further, in the present heating system, the structure of the portion corresponding to the layer of stones 5a and sand 5b may be any structure such as conventional heat storage concrete as long as heat can be stored, and the portion corresponding to the layer of charcoal 5c is It may be just a space.

[Roofing Material] Next, the roofing material 16 will be described. The illustrated roofing material 16 includes a wooden panel main body 17 having a thin box-like hollow structure, a layer of a heat insulating material 18 loaded in a mat state of an appropriate thickness in the hollow portion of the wooden panel main body 17, and the remaining hollow portion. It consists of a layer of charcoal 19 that fills the space.

The wood panel main body 17 has, as basic components, face plates 17a and 17b made of plywood which form both front and back surfaces, and four wood side frame pieces 17c to 17f which form a peripheral frame. Face plates 17a and 17b are fixed to both front and back surfaces of a square ring 17c to 17f to form a thin box-shaped hollow structure. Further, the wooden panel main body 17 of the embodiment is
In addition to this basic structure, an electromagnetic wave shield layer 20 formed by pasting an aluminum foil on the entire inner surface of the face plate 17a on the front side or applying a paint having an electromagnetic wave shield effect, and the center of the thickness of the wooden panel main body 17 Middle partition plate 17g for partitioning in the (front and back) direction, face plates 17a and 17b, and middle partition plate 17g
Frame-shaped partition member 17 for partitioning the space between spaces into small sections
h is provided. Therefore, the wooden panel main body 17 is made of wood and exhibits high rigidity while being lightweight.

In the present embodiment, the layer of the heat insulating material 18 is formed by finely crushing paper (newspaper) and spraying cellulose fibers to which a sizing agent is added onto the partition plate 17g. Further, the layer of the charcoal 19 is made of charcoal in the present embodiment, and is filled between the intermediate partition plate 17g and the back face plate 17b. The charcoal 19 may be replaced with bamboo charcoal made of bamboo.

The roofing material 16 is constructed as described above, and as shown by the chain double-dashed line in FIG. 5, a required number of sheets are lined up and fixed on the rafters 21 which are the frame of the roof, and a waterproof sheet is further provided on the surface thereof. And attach the collector 3 directly,
For example, tiles are laid in the other vacant parts.

Since the roofing material 16 of the present invention has a layer of the heat insulating material 18 preliminarily formed in the hollow portion, it is not necessary to separately install the heat insulating material at the site and the workability is excellent. Further, since a layer of charcoal 19 is provided in the hollow portion, the charcoal 19 also exerts humidity control, deodorization, and insect control action, so that the durability of the roofing material 16 itself is high and the comfortability is improved. Will also contribute significantly.

Although the roofing material 16 of the present invention has been described with reference to the embodiments, the invention is not limited to the above embodiments. For example, in the embodiment, the cellulosic fiber is used for the heat insulating material 18, but other heat insulating material may be used. However, the heat insulating material 18 of cellulosic fiber is excellent in that it is a natural material, does not contain harmful substances, and can contribute to the recycling of waste paper. Further, the method of loading the heat insulating material 18 in the mat state is not limited to the spraying of the cellulosic fibers as in the embodiment. For example, a thin sheet having a heat insulating property is stacked in many layers to form the mat state. Or a matte state by foaming with a foaming agent.

Further, in the embodiment, the wooden panel main body 17 is formed with the intermediate partition plate 17g and the partition member 17h. However, when the wooden panel main body 17 is made small, both may be unnecessary, or the intermediate partition plate 17g may be omitted. It may be omitted and only the partition member 17h may be formed. In those cases,
A layer of charcoal 19 adheres to a layer of heat insulating material 18.

Further, in the embodiment, the layer of the heat insulating material 18 and the charcoal 1 are used.
Although the layers of 9 are formed to have the same thickness, it is possible to make one of them thicker and the other thinner. Further, the place where the electromagnetic wave shield layer 20 is provided is not limited to the embodiment. For example, the front and back surfaces of the inner partition plate 17g are coated with a paint having an electromagnetic wave shield effect, or the surface of the wooden panel main body 17 (of the face plate 17a). The surface) may be coated with a paint having an electromagnetic wave shielding effect. In the latter case, face plate 1
Since the surface of 7a is protected by paint, waterproof performance is improved,
In addition, a side effect that the front and back of the roofing material 16 can be easily distinguished can be expected.

The roofing material of the present invention includes the following technical ideas. That is, "a thin box-shaped hollow wooden panel main body, a layer of a heat insulating material loaded into the hollow portion of the wooden panel main body in a matte state of an appropriate thickness, and a layer of charcoal filling the remaining space of the hollow portion. A layered electromagnetic wave shield layer, and a middle partition plate at the boundary between the heat insulating material layer and the charcoal layer in the wood panel main body, and the face plate and the middle plate that form both front and back surfaces of the wood panel main body. A roofing material in which a partition member is provided between partition plates to partition the inside of the hollow section into multiple small sections. "

[0034]

[Indoor warming means] Next, the indoor warming means will be described. In the solar house 1, as shown in FIG. 1, a curtain 23 that can be automatically opened and closed is installed in a large opening 22 having a glass door 22a. This curtain 23 is, for example, as shown in FIG. 9, a roll-up type roll curtain 23.
a, a chain 23b for manual operation provided at one end of a winding shaft (not shown) of the roll curtain 23a, and a clutch built-in motor 23c provided at the other end of the winding shaft of the roll curtain 23a. When the motor 23c is rotated forward and backward, the built-in clutch is engaged and the roll curtain 23a moves up and down. On the other hand, when the motor 23c is OFF, the built-in clutch is disengaged and the chain 23b allows the roll curtain 23a to be manually operated. .

The opening and closing of the curtain 23 is controlled by a separate control device (not shown). A timer circuit and an optical sensor 24 installed on the outer wall surface of the solar house 1 are connected to the control device, and the curtain 23 is opened and closed under two conditions of time and light quantity.

Next, an example of automatic control of the curtain 23 will be described with reference to the flowchart of FIG. First, the power is turned on, and the timer is set in step S1. The set time is, for example, 16:30. During this time of winter,
Although the brightness remains before the sunset, the amount of solar heat can hardly be expected, and therefore the opening 22 that has been the intake of solar heat until then is likely to turn into a heat radiation port.

Next, in step S2, it is determined whether or not the set time has been reached, and if it is before the set time, the process moves to step S3 to determine whether or not the outside is dark by the signal of the optical sensor 24. If it is determined that the outside is not dark, step S
Return to 2.

Next, while steps S2 and S3 are repeated as described above, the time set by the timer is reached, but in that case, the process proceeds from step S2 to step S4 and the curtain 23 is closed. Specifically, the motor 23c of the curtain 23 is operated to lower the roll curtain 23a.

On the other hand, when it is determined that the set time has not been reached in step S2, but it is determined that the outside has become dark in step S3, it is considered that the weather has deteriorated and the curtain 23 is closed. The curtain 23 may be closed immediately after the light sensor 24 responds, but after a few minutes from the first reaction of the light sensor 24, the light sensor 24 should be used again to check the outside brightness before closing the curtain 23. Good to do.
By doing so, it is less likely that the curtain 23 will be closed in response to a temporary change in the situation for a very short time.

Next, after closing the curtain 23, step S
In step 5, it is determined whether or not the timer is changed, that is, whether or not there is a key input for changing the timer. If there is no key input for changing the timer, the process returns to step S2 and the curtain 23 is closed at the same time every day. If the timer change is selected, the set time is changed in step S1 and the above operation is repeated. In the embodiment, the opening operation of the curtain 23 is manually performed by the chain 23b.
Of course, it is also possible to use the timer to perform the opening operation of the curtain 23 by the motor 23c. For example, the curtain 23 may be set to automatically open at 7 am. By doing so, you can expect a natural awakening from the morning sunlight.

Although the indoor heat insulating means of the present invention has been described with reference to the embodiment, the invention is not limited to the above embodiment. For example, although the roll-up type curtain 23 is illustrated in the embodiment, a blind that can be automatically opened and closed may be used. The blinds are opened and closed by changing the angle of the louver. Further, the concept of the curtain or blind of the present invention also includes a roll-up door (so-called shutter) made of metal or synthetic resin that is automatically opened and closed and is installed outside the opening 22. Further, the curtain 23 is not limited to the roll-up type, and may have a general single-open or double-open structure in which the cloth is slid horizontally.

Further, the automatic opening / closing type curtain 2 of the embodiment
If the ON / OFF function of the interior lighting is added to 3, it will be useful for crime prevention measures in houses. That is, for example, since the operation panel of the control device is provided with the above-mentioned timer input key, if a mode change key is provided in a part of the operation panel and the absence mode is selected there, the timer setting causes, for example, 4 pm The program that the curtain 23 is closed at 30 minutes, the room lighting is turned on at 5 pm, the room lighting is turned off at 11:00 pm, and the curtain 23 is opened at 7 am is repeatedly executed every day during absence. Alternatively, a timer and an optical sensor 24 are used together, and when the outside of the room becomes dark due to the detection of the optical sensor 24, the curtain 23 is closed and indoor lighting is turned on, and the timer is turned off to turn off the indoor lighting at 11:00 pm. Thus, the program of opening the curtain 23 when the outside becomes bright is repeatedly executed every day during absence. By doing so, a high crime prevention effect can be obtained because it looks as if a person is inside the room.

Further, although the present invention is mainly effective in winter, it can be used as a countermeasure against heat even in summer. That is, the timer is turned off and the optical sensor 24
If you enable only this, you can repeat the operation that the curtain 23 closes when the outside becomes bright and the curtain 23 opens when it becomes dark, so it is possible to suppress the rise in room temperature due to solar radiation during the day, and after sunset The hot air trapped inside the room can escape from the opening 22 through the glass.
Of course, such opening and closing of the curtain 23 may be performed by a timer.

When there are people in the room, the curtain 23
When there is a request to disable the automatic opening and closing of the vehicle (for example, a case where it feels uncomfortable), for example, the room lighting and the control device of the curtain 23 are electrically connected, and when the room lighting is turned on, It is possible to deactivate the automatic control of the curtain 23 by assuming that the vehicle is present. In that case, the person in the room manually operates the curtain 23 at his own discretion. It should be noted that the merit of performing the person detection by linking with the room lighting is low in cost, but if the accuracy of the detection is pursued, another sensor such as an infrared sensor may be used.

The indoor heat insulating means of the present invention includes the following technical ideas. `` Install a curtain or blind at the opening such as a window or door of the building so that it can be at least automatically closed, and set the timer so that the curtain or blind closes before the outside becomes dark. Indoor warming means set to close when the light sensor detects that it has become dark before the set time. "

Although the present invention has been described above with reference to the embodiments, the present invention is of course not limited to the above embodiments. For example, although the solar house 1 of the embodiment is configured to include all three elements of the heat storage material 5, the roof material 16, and the indoor heat insulation means, the heat storage material 5 and the roof material 16, or the heat storage material 5 and the indoor heat insulation means. Further, the roof material 16 and the indoor heat insulating means may be used in an appropriate combination.

[Effect of the invention] [Effect of claim 1] When the stone is granular, gaps are formed between the grains, so the heat storage performance is lower than that of heat storage concrete. It can be almost compensated by filling. In addition, since the mixture of stone and sand has a higher thermal conductivity than thermal storage concrete, in the case of a solar house, the time from the start of solar heat collection until the room temperature rises is shortened, and the daytime From the stage, solar heating starts to work. The heat of heating is not limited to the heat storage material under the floor, but is stored by the entire wall such as the interior wall and ceiling, so if the heating by solar heat starts early in the daytime, the entire building will be effective as a heat storage means for solar heat. Can be used. On the other hand, the roofing material has a layer of heat insulating material preliminarily formed in the hollow part, so there is no need to separately provide a heat insulating material at the site, and since a layer of charcoal is provided in the hollow part, it is adjusted. It also exhibits moist, deodorizing and insect repellent effects, and the electromagnetic wave shield layer effectively prevents the intrusion of electromagnetic waves emitted from power lines. Therefore, by combining this roof material and the heat storage material, it is possible to realize high performance of the solar house.

[Effect of claim 2] If the timer is set with reference to the time zone in which the sunlight shines through the opening and raises the room temperature in winter, the room temperature will drop even if the user goes out with the curtain open. The curtain automatically closes at the timing of turning, reducing the heat radiation from the opening, and when the weather worsens and the outside becomes dark due to snow or rain before the time set by the timer, the light sensor detects the change in light Even before the set time, the curtain is closed to prevent wasteful heat radiation from the opening. Therefore, since the heat insulating effect of the building can be effectively enhanced, the performance of the solar house can be improved by combining this with the heat storage material.

[Effect of Claim 3] This solar house exhibits a very high performance due to the synergistic effect of the heat storage material, the roof material, and the indoor heat insulating means.
