DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar system house that uses solar energy to perform heating or the like using air heated by the sun.

[0002]

2. Description of the Related Art The increase in CO ₂ as a result of human activities has now threatened the global environment itself. Much of this is due to the advanced nations acknowledging energy-intensive civilizations.

[0003] If many developing nations are the ideal models for this developed nation, the global environment will undoubtedly have to move toward ruin. But does this mean that the riches enjoyed by developed nations can only be abandoned by developing nations? Mass consumption of resources and energy should never be a privilege granted only to developed countries.

Now, what advanced nations need to do is to improve their lives without lowering their level of living.
The goal is to create a way to reduce environmental impact. Therefore, it is necessary to optimize the use of solar energy for indoor heating, cooling, ventilation, dehumidification, and hot water supply by constructing houses and buildings that flexibly respond to external environmental conditions as well as wind and other weather conditions. Can be

[0005] By the way, traditional Japanese houses have features such as large roofs, deep eaves, wide openings, edges, open planes, floors higher than the ground, and floors. This unique form of Japanese housing can be said to have arisen from the interaction and fusion with Japanese nature. The wide openings and raised floor system were obviously designed to cope with the high temperature and humidity of summer in Japan, and architectural innovations to get cool through ventilation required this form. And it was easily realized by using the Japanese style construction method-wooden frame construction method which can be said to be very unique.

[0006] However, in using solar heat, the Japanese-style method had a major difficulty. First of all, the Japanese-style construction method, in which a pillar is set up, a roof is placed on it, and walls and windows are freely provided, is inconvenient in terms of heat insulation and airtightness of the building, and the building parts that can obtain heat capacity are limited. .

However, even in such a traditional Japanese house, as a method of utilizing solar heat, a large opening is provided in the southern part of the house to receive a large amount of winter solar radiation, and a part of it is opened in summer. Ventilation is sometimes performed.

Further, by taking this step one step further, a sunroom is formed outside the living room, and this is used as a greenhouse to take warm air from here into the living room. In this case, only heat is stored in the air. For example, as shown in FIG. 11, the outside of the concrete outer wall 51 is covered with a glass 52 or the like, and the air circulation path
In this case, the outer wall 51 itself acts as a heat storage body, and stable heat supply can be obtained.

[0009] However, all of these methods are limited to the control of the indoor space relatively facing south, and have a drawback that a large temperature difference is generated between the indoor space facing north and the indoor space.

In the United States, as a system for collecting solar heat and storing it, UnitedStates Patent No.
No. 4,304,219, “SOLAR ENERGY CONT
OROL SYSTEM, but this is BUIL
A solar heat storage device separate from DING is used as a component, and BUILDING itself is not used for collecting and storing solar heat.

[0011] The inventors have previously described the United States Patent
No. 4,967,729, "Solar System House"
Has obtained a patent right. In this, as shown in FIG. 12, an air passage 2 having a roof gradient is formed immediately below a metal roof plate 1 made of a color iron plate, and one end of the air passage 2 is connected to an air inlet 3 at an eave or the like. And the other end of the air flow path 2 is communicated with a ridge duct 4 as a maturation duct.

A handling box 5 provided with a backflow prevention damper 6, a heat collecting fan 7 and a flow path switching damper 8 therein is installed in a hut space 29 as an attic space, and the flow path switching damper 8 of the handling box 5 flows out. One of the sides is opened outdoors by the exhaust duct 9. Also, the inflow side of the backflow prevention damper 6 of the handling box 5 is communicated with the ridge duct 4 through the duct 32, and the other one of the outflow side of the flow path switching damper 8 is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 is open to the air circulation space 13 between the floor concrete 12 and the floor concrete 12 as a heat storage body under the floor. Further, the air circulation space 1
A floor outlet 14 was provided from 3 to the room.

A hot water coil 15 is provided in the inside of the handling box 5 or between the handling box 5 and the ridge duct 4.
The hot water storage tank 17 and the circulation pump 19 are connected to the hot water storage tank 17, and a hot water supply boiler 18 for additional heating is provided in the middle of the hot water storage tank 17, and a hot water supply pipe 21 connected to a bath, a washroom, and a kitchen is connected.

In this manner, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air entering the air passage 2,
This warmed air rises along the roof slope. 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 into the falling duct 10, and flows between the heat storage soil concrete 11 and the floor panel 12. Into the air circulation space 13. In this air circulation space 13, the heated air directly warms the floor below the floor via the floor panel 12, heat is stored in the heat storage-soil concrete 11, and is directly blown into the room as warm air from the floor outlet 14. The three types of heating action are performed.

On the other hand, in the hot water removing coil 15, the heat medium fed from the hot water tank 17 through the circulation pipe 16 by the circulation pump 19 is heated and stored in the hot water tank 17 as hot water. The water is then reheated by a hot water supply boiler 18 for additional heating and supplied to various locations from a hot water supply pipe 21.

[0016]

In such a solar system house, the operation is performed by using the handling box 5, and the most driven in the handling box 5 is the heat collecting fan 7. The heat-collecting fan 7 is normally driven by a drive motor connected to a commercial power supply of 100 V as a power source, and a large part of the running cost of the entire house is its electricity cost.

However, in the first place, the problem of the solar system house is to utilize solar energy, and it is desirable to reduce the running cost by using more natural energy for the operation of such a handling box.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to construct houses and buildings that flexibly respond not only to wind and other weather conditions but also to external environmental conditions to provide indoor heating, cooling, ventilation, dehumidification, and the like. To provide a solar system house that can optimize the use of solar energy for hot water supply, reduce running costs by using solar cells, and enable appropriate operation according to the amount of solar radiation. is there.

[0019]

According to the present invention, in order to achieve the above object, first, a solar heat collecting section is provided on a roof, and a heat collecting duct is communicated with the solar heat collecting section. The heat duct is connected to the handling box, and the handling box switches the flow between the backflow prevention damper that prevents backflow toward the heat collection duct and the falling duct and the exhaust duct that opens to the outside. A path switching damper, and a heat collecting fan provided between the backflow prevention damper and the flow path switching damper are disposed therein, and a drive motor of the heat collecting fan of the handling box is DC (direct current). The gist is that a motor is used and a solar cell and a storage battery connected to the solar cell are connected as a power supply.

Secondly, the solar heat collecting section comprises a roof steel plate and an amorphous silicon solar cell laminated thereon, and the roof of the amorphous silicon solar cell is covered with a resin-coated roof plate. The gist of the invention is that an air flow path having a roof gradient is formed immediately below a plate.

Thirdly, in the summer, during the daytime, an exhaust operation is performed by connecting a flow path switching damper to an exhaust duct, and at night, the flow path switching damper is connected to a falling duct, so that night-time radiant cooling for taking in outside air into a room. Operation, fourth, a DC motor is also used as a drive motor for the backflow prevention damper and the flow path switching damper, and this DC motor is connected to a storage battery as a power source. A gist of the invention is to provide a temperature sensor in a duct, and to turn on / off a drive motor of a heat collection fan and open / close a damper based on a temperature detected by the temperature sensor.

Sixth, the heat collection duct is a ridge duct installed indoors or a roof duct installed outdoors. Seventh, the lower end of the falling duct is connected to the underfloor air circulation space. It is opened, and an outlet is provided from the underfloor air circulation space to the room, and the underfloor air circulation space is a space between the thermal storage clay concrete and the floor panel,
Or, the gist is that the lower end of the falling duct opens directly into the room, or that the lower end of the falling duct opens both into the underfloor air circulation space and directly into the room. Is what you do.

According to the first aspect of the present invention, the present invention is characterized in that heat is first collected on a roof. What is the characteristic of solar energy as energy? It is "light, wide, and even"
It can be said that. The lack of intensive high temperatures, such as the heat available from petroleum, makes them unsuitable for large, intensive power generation. In other words, the use of solar energy is the most realistic that each building uses its “roof”, which fits well with the characteristics of energy. Therefore, the solar system house of the present invention is a "roof" which receives the sun most widely, and collects solar energy and takes it into a building.

The height restrictions on buildings in the area are severe,
Even if you ca n’t get sunshine indoors for that,
Most of the time, the roof is filled with solar energy. In other words, this use adds the new function of "capturing heat" to the function of "shelter" that prevents the roof from rain and wind.

Next, heat is transferred by air. When taking heat into a room, a common practice is to transfer it to water. In the solar system house of the present invention, "air" is warmed and taken in instead of water. The reason for this is that water collection has many difficulties. That a single drop of water must be kept from leaking, that solar energy often causes the water to boil and withstand the vapor pressure of the boiling, that it freezes, and that the tube expands and contracts. Is raised as the reason. On the other hand, the air does not bother anyone, even if it leaks a little. Also, since air is a gas, it cannot boil. Therefore, it is very safe to use air.

Further, by using and controlling a solar battery and a storage battery as power sources for a heat collecting fan and a damper motor of a handling box and a hot water pump in daytime, energy saving can be achieved. In addition, when the solar radiation is strong, the amount of power generated by the solar cell is large. As a result, the heat collecting fan can be driven according to the degree of the solar radiation, for example, the air flow of the heat collecting fan increases. In particular, the fan in the handling box does not use a commercial power source as a power source, but is electrically connected directly to the solar cells stacked on the roof. Drive, automatic control, and more energy saving.

According to the second aspect of the present invention, it is possible to obtain solar heat at the same time as electricity by integrating the solar cell into a roofing plate as a building material and integrating the solar cell. There is no need to provide a place, and it does not hinder the heating of the roof shingle by the sunlight, and the roof structure itself can be used as a solar cell mount, so the cost of the mount can be reduced and the roof can be constructed. At the same time, the installation of the solar cell is completed, so that the cost for installation work of the solar cell can be saved. At that time, the efficiency of the solar cell is several percent of the acquired solar energy, and has substantially no effect on the solar heat collection performance.

The amorphous silicon solar cell constitutes a solar cell module as an integral type with a steel plate for a roof, and has a strength lined with the steel plate for a roof. Therefore, this solar cell module can be bent up and down, and depending on the bending angle, even if it is bent at the power generation part of the solar cell, it does not impair the function of the solar cell, and it has various styles and forms. Can be applied to roofing materials. Furthermore, amorphous silicon type solar cells have a relatively small decrease in power generation due to temperature rise.However, there is an air flow path with a roof gradient directly under the roof plate, and the air flowing through this makes the roof plate reach a certain temperature or higher. Since it does not rise, power generation performance can be maintained.

According to the third aspect of the present invention, in addition to the above-described operation, especially at night, the outside air which is radiated and cooled by passing through the solar heat collecting portion provided on the roof is taken into the room, so that it is comfortable. Environment can be created.

According to the fourth aspect of the present invention, in addition to the above operation, the power generated by the solar cell can be used as the power supply for the drive motor of the damper, so that the running cost can be further reduced. .

According to the fifth aspect of the present invention, the timing of the summer exhaust operation and the winter heat collecting operation can be performed based on the temperature detected by the temperature sensor provided in the wing duct, and appropriate automatic control can be performed. Becomes possible.

According to the sixth aspect of the present invention, since the duct as the heat collecting box is a ridge duct installed indoors, the duct can be installed without taking up an installation space by using a ridge space which is not used originally. Can be installed.

According to the seventh aspect of the present invention, since the duct as the heat collecting box is an on-roof duct installed outdoors, the duct installation work can be performed from the outside at the stage of the roof work, and Ducts can be installed even in buildings where the building space is not sufficient.

According to the eighth aspect of the present invention, the lower end of the falling duct is opened to the underfloor air circulation space, and the outlet from the underfloor air circulation space to the room is provided. While air conditioners and fan heaters, which are the mainstream of heating appliances, are called "hot air heating", the present invention warms a wide floor surface at a relatively low temperature by passing warm air under the floor, and reduces the radiant heat. This is one of the "low-temperature radiant heating" in which the room air is heated without excessively increasing the indoor air.

"Hot air heating" intermittently heats only one room and creates a temperature difference between the upper and lower parts of the room. In "low temperature radiant heating", such a large temperature difference between the upper and lower parts and the blowing of unpleasant air are generated. In addition, since the feet are warm due to conduction heat from the floor, a comfortable indoor environment of "head cold foot fever" can be realized.

According to the ninth aspect of the present invention, the underfloor air circulation space is a space between the thermal storage clay concrete and the floor panel, and stores heat under the floor. The heat collected on the roof and taken in with air as the medium, if left alone, will cool down when the sun goes down. Even in the cold winter daytime, direct gain allows for some amount of solar radiation through the windows, and if the heat collected by the roof is secured as needed, the room temperature will increase.

That is, solar energy is unevenly distributed in the daytime, and when it is collected and radiated indoors as it is,
Conversely, the room temperature becomes too high. In order to avoid this, in the present invention, it was considered that heat collected during the daytime is stored in the concrete under the floor, and the heat collection site is separated from the heat storage site. Concrete has a large heat capacity (the amount of heat that can be stored) and thermal conductivity (the ease with which heat can be transmitted). This property of concrete adapts to a daily cycle of storing heat during the day and radiating heat at night.At night, the outside temperature decreases, and the heat stored under the floor begins to radiate during the day. Used for indoor heating.

According to the tenth aspect of the present invention, the lower end of the falling duct is opened directly into the room, thereby collecting heat on the roof and radiating the heat taken in with the air as a medium into the room as it is. It is also possible to heat only one specific room intermittently in a short time.

According to the eleventh aspect of the present invention, the effects of the ninth to tenth aspects can be exhibited.

Embodiments of the present invention will be described below in detail with reference to the drawings. The basic structure of the solar system house of the present invention is also United States Patent No. 4,967,
Similar to the solar system house of No. 729, the solar system house of the present invention has a sloped roof as shown in FIG. , An air flow path 2 having a roof gradient was formed. The lower side of the air flow path 2 was shielded by heat insulation, and one end of the air flow path 2 was opened as an air inlet 3 at the eaves or the like. Further, the other end of the air passage 2 is located at a high portion of the roof to serve as an air outlet,
A duct 31 is connected to the duct 31 and communicates with the ridge duct 4 as a maturation duct.

The ridge duct 4 may be a semi-circular duct as shown in FIG. 5 in addition to the circular duct as shown in FIG.

Further, as shown in FIG. 6, the maturation duct may be installed outdoors and may be configured as a roof duct 36.

The solar heat collected by such a roof is stored and stored.
As the heat dissipating part, the soil concrete 11 is used as a heat storage under the floor. Therefore, an air circulation space 13 is provided between the concrete floor 11 and the floor panel 12, and a floor outlet 14 is provided from the air circulation space 13 to the room. Panel 12
Warming directly below the floor through the floor
Three types of heating actions are performed: heat is stored at 1 and air is directly blown into the room from the floor outlet 14 as warm air.

The handling box 5 is installed in the attic space 29, which is an attic space, to connect the portion for collecting solar heat and the portion for storing and radiating solar heat.

The handling box 5 is a box in which a backflow prevention damper 6, a heat collecting fan 7, and a flow path switching damper 8 are provided. One of the outlets of the flow path switching damper 8 of the handling box 5 is opened to the outside by the exhaust duct 9.

Further, the inflow side of the backflow prevention damper 6 of the handling box 5 is communicated with the ridge duct 4 through the duct 32, and the other one of the outflow side of the flow path switching damper 8 is connected to the upper end of the falling duct 10. connect. The lower end of the falling duct 10 is a slab concrete 11 as a heat storage body under the floor.
It opened to the air circulation space 13 between the floor panel 12 and the floor panel 12.

A hot water coil 15 is provided inside the handling box 5 or between the handling box 5 and the ridge duct 4.
The hot water storage tank 17 and the circulation pump 19 are connected to the hot water storage tank 17, and a hot water supply boiler 18 for additional heating is provided in the middle of the hot water storage tank 17, and a hot water supply pipe 21 connected to a bath, a washroom, and a kitchen is connected.

In this manner, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air entering the air passage 2,
This warmed air rises along the roof slope.

Then, the heated air is collected in the ridge duct 4 and then enters the handling box 5 by the heat collection fan 7, and the falling air duct 1 falls from the handling box 5.
0, flowing down into the concrete and the floor panel 1
2 into the air circulation space 13. In the air circulation space 13, the heated air directly warms under the floor via the floor panel 12, heat is stored in the heat storage soil concrete 11, and is directly blown into the room as warm air from the floor outlet 14. Performs street heating.

On the other hand, in the hot water removing coil 15, the heat medium fed from the hot water storage tank 17 through the circulation pipe 16 by the circulation pump 19 is heated and stored in the hot water storage tank 17 as hot water. The water is then reheated by a hot water supply boiler 18 for additional heating and supplied to various locations from a hot water supply pipe 21.

In such a solar system house using heated air collected by sunlight as shown in FIG. 1, in a high temperature season such as summer, when heating is not required, all heated air heated by the roof panel 1 is outside air. Must be released and discarded.

In this case, if the falling duct 10 which is one of the outflow sides is closed by the flow path switching damper 8 and the exhaust duct 9 which is the other one of the outflow sides is opened, the heated air is removed from the handling box 5. Is discharged outside through the exhaust duct 9. The heated air is handled in the handling box 5
Since the hot water coil 15 is heated by passing the hot water, it can be ensured that hot water can be obtained by utilizing solar heat even at high temperatures such as in summer.

Further, the fan 7 for heat collection is operated at night in summer, and cool air at night is taken into the air flow path 2 immediately below the metal roof plate 1, and radiative cooling from the roof surface is also acted on, thereby causing this air to flow. Underfloor heat storage unit and floor panel 12 through falling duct 10
, And can be stored in the concrete between the floors 11 as a heat storage body under the floor.

It is to be noted that the heat storage of the hot or cold heat may be carried out separately from the soil concrete 11. The example shown in FIG. 8 is an example in which a heat storage body 42 is provided in the air flow space 13 between the floor panel 12 and the air flow space 13.

According to the present invention, a panel (PV panel) of a solar cell 22 is installed on a roof which is a solar heat collecting section, while a sirocco fan is used as a heat collecting fan 7 of the handling box 5, and a drive motor 7a thereof is used. Used a DC (direct current) motor. DC motors were also used for the drive motors 6a and 8a of the backflow prevention damper 6 and the flow path switching damper 8.

The solar cell 22 is an amorphous silicon solar cell, and the roof panel 1 is composed of a roof steel plate 37 and an amorphous silicon solar cell 22 laminated thereon via a filler 38 as shown in FIG. A solar cell module 40 was formed by laminating a fluorine resin 39 as a resin coating on the upper surface of the amorphous silicon solar cell 22 with a filler 38 interposed therebetween.

Although not shown, the amorphous silicon solar cell 22 is formed by laminating electrodes and an amorphous silicon thin film on the surface of a stainless steel thin plate having a thickness of 125 μm.

As described above, the solar cell 22 constitutes a solar cell module as an integral type with the roof panel 1, and heat collection by the roof panel 1 and power generation by the solar cell 22 can be performed simultaneously. At that time, the efficiency of the solar cell is several percent of the acquired solar energy, and has substantially no effect on the solar heat collection performance.

Further, the amorphous silicon solar cell 2
Numeral 2 designates a solar cell module 40 as an integral type with the roof steel plate 37.
It has the strength backed by. Therefore, the solar cell module 40 can be bent upward and downward, and depending on the bending angle, even if bent at the power generation portion of the solar cell 22, the function of the solar cell is not impaired. It can be applied to roofing material of form.

In the case of an amorphous silicon type solar cell, the power generation with a rise in temperature is relatively small, but there is an air flow path having a roof gradient immediately below the roof plate.
Since the roof slab does not rise above a certain temperature due to the air flowing through it, power generation performance can be maintained.

In addition to this, since the roof structure itself can be used as a solar cell mount, the cost of the mount can be reduced, and the installation of the solar cell is completed simultaneously with the installation of the roof. Costs can be saved.

As shown in FIG. 3, a driving motor 7a for the heat collecting fan 7 is connected to the solar cell 22, and a storage battery 23 is connected to the solar cell 22 via a DC / DC converter 33. The motor 7a is connected to the storage battery 2
3, and the drive motors 6a, 8a and the control device 20 are also connected to the storage battery 23.
The drive motor 7a of the heat collection fan 7 is AC (alternating current).
It is connected to a commercial power supply 34 via an AC / DC converter 35.

A relay contact R5 is inserted in the circuit connecting the solar cell 22 and the drive motor 7a of the heat collection fan 7, and the electricity from the solar cell 22 is supplied to the drive motor 7a of the heat collection fan 7 and the storage battery 23. It flows through the storage battery 23 until the relay contact R5 that activates the heat collection fan 7 is turned on. Thereafter, when the relay contact R5 is turned on, electricity also flows to the heat collecting fan 7.

The circuit of the storage battery 23 drives basic control. Relay contact R5 is ON / OFF of heat collecting fan 7
The relay contact TR1-4 is for opening and closing the drive motors 6a and 8a of the damper, and the relay contact R6 is for ON / OFF of the circulation pump 19 for removing hot water.

The solar cell 22 'only activates the circulation pump 19 for removing hot water, but is synchronized with the activation of the heat collection fan 7 in order to increase efficiency.

The use of the solar cell 22 will be described. The case of using solar cells in winter is the same as the conventional example. In the morning when sunlight does not hit the shingle 1 yet, the air temperature in the ridge duct 4 is also low. In this case, the backflow prevention damper 6 closes the ridge duct 4 side. Further, the flow path switching damper 8 closes the exhaust duct 9 side, and connects the heat collection fan 7 and the falling duct 10.

When sunlight hits the solar cell 22, power is generated,
The storage battery 23 is charged through the control device 20. Storage battery 2
When the battery 3 is sufficiently charged, a circuit in the control panel of the control device 20 is activated. Further, the heat collecting fan 7, the backflow prevention damper 6, the flow path switching damper 8, and the circulation pump 19 in the handling box 5 are linked with the circuit in the control panel.

When the sunlight hits the shingle 1 and the temperature inside the ridge duct 4 exceeds the set temperature, the backflow damper 6
Turns over and opens the ridge duct 4 side. Then, the heat collecting fan 7 starts to start collecting heat. The outdoor air is first introduced into the air flow passage 2 formed immediately below the roof panel 1 from the air intake port 3 such as the eaves by the heat collecting fan 7, and is heated by the roof panel 1 heated by the sunlight here. After being collected in the wing duct 4, it enters the handling box 5. Even if the solar cell 22 is on the roof, the area occupied by the solar cell 22 is not so large, so that the existence of the solar cell 22 does not hinder the heating of the air passage 2 in the roof panel 1.

The heated air entering the handling box 5 flows down from the handling box 5 through the falling duct 10, and the slab concrete 11 and the floor panel 12 for heat storage.
And directly under the floor via the floor panel 12, heat is stored in the slab concrete 11, and is directly blown into the room as warm air from the floor outlet 14. By performing three types of heating action, the room temperature gradually rises.

When a dedicated switch on the control device 20 is pressed, the circulating pump 19 is operated and the circulating pipe 1 is removed.
The hot water starts to circulate between the hot water removing coil 15 and the hot water removing coil 6. The temperature in the hot water storage tank 17 rises while the heat medium circulates slowly in the hot water collecting coil 15, and when the temperature falls below a certain level, the pump stops and hot water collection stops.

When the heat collecting fan 7 is driven, the cooling fan 28 built in the heat collecting fan 7 is driven, so that the motor of the heat collecting fan 7 is cooled.

In this way, before the solar radiation, the control relay (relay contact R5) is opened and the storage battery 23 is consumed, and when the solar radiation occurs, the solar battery 22 generates electric power and the storage battery 23
Charge. (Because the voltage passes through the DC / DC converter 33, the charging becomes constant voltage when the voltage falls within the set voltage range.)

Thereafter, the ridge duct bimetal thermostat (MSS summer time / MSW winter time) linked with the first temperature sensor 25a, which will be described later, which controls the temperature is turned on, and the electricity of the solar cell 22 is connected to the heat collecting fan 7. . At this time, the heat collection fan 7 starts. Thereafter, although the storage battery 23 is naturally fully charged, electricity flows directly to the control relay (relay contact R5).

When the solar battery 22 does not generate enough power in the rain or the like even in the event of sunshine and the heat collection fan 7 does not start, only the storage battery 23 is charged. By repeating such charging and discharging, a circuit (independent control circuit) that does not use the AC (alternating current) commercial power supply 34 in terms of energy is obtained.

On the other hand, the backflow prevention damper 6 opens the ridge duct 4 side, as shown during daytime heat collection in a season when heating is not required, such as in summer. Further, the flow path switching damper 8 closes the heat collecting fan 7 and the falling duct 10 side, and connects the heat collecting fan 7 and the exhaust duct side. When the heat collection fan 7 is driven in this manner, the heated air collected in the ridge duct 4 from the air inlet 3 such as the eaves through the air flow path 2 enters the handling box 5 and heats the hot water coil 15. Then, it flows through the exhaust duct 9 and is discarded outside.

During the summer night, the backflow prevention damper 6 opens the ridge duct 4 side in the same manner as in the daytime, but the flow path switching damper 8 includes the heat collection fan 7 and the falling duct 10.
And the heat collecting fan 7 and the exhaust duct 9 are closed. The power of the drive motor 7a of the heat collection fan 7 is supplied from the solar cell 22 or the storage battery 23 to an AC (AC) commercial power supply 3.
Switching is performed so that the AC / DC converter 35 is connected to four.

In this state, when the heat collecting fan 7 of the handling box 5 is turned, the cool air at night enters from the air inlet 3 such as the eaves and the like into the air passage 2 formed immediately below the roof plate 1 and radiatively cools there. Is made. Then, after being collected in the ridge duct 4, it enters the handling box 5, falls from the handling box 5, flows down the duct 10, and enters the air circulation space 13 between the heat storage soil concrete 11 and the floor panel 12. In addition, the cooling operation is performed such that the cold storage is performed on the heat storage concrete 11 and the cold air is directly blown into the room from the outlet 14 as the cool air. (Night radiation cooling operation)

Further, the solar system house of the present invention performs the following temperature control so that
Effective use of the system house can be rationalized in connection with energy saving in using the storage battery 23 and in connection with taking in outside air and performing radiant cooling in the nighttime in summer.

As shown in FIG. 3, a first temperature sensor 25a is provided in the ridge duct 4 for detecting the heat collection temperature in the ridge duct, and a high-temperature sensor for detecting the heat collection temperature in the handling box 5 is provided. Second temperature sensor 25
b is provided.

A thermostat 24 is provided in the room for switching between heating and exhaust. Further, a third temperature sensor 25c as a low-temperature sensor is provided in the hot water storage tank 17 so as to correspond to the second temperature sensor 25b as the high-temperature sensor. Further, a fourth temperature sensor 25d is provided for sensing the room temperature and a fifth temperature sensor 25e is provided for sensing the outside air temperature for taking in outside air at night in summer or the like. Further, a humidity sensor 26 is provided for sensing the humidity of the outside air.

The temperature sensors 25a to 25e and the humidity sensor 26 are connected to the control device 20. The driving motor of the backflow prevention damper 6 of the handling box 5, the motor of the heat collecting fan 7, the circulation pump 19, the solar battery 22, The storage battery 23 and the like are also connected to the control device 20.

In the morning when the sunlight does not hit the shingle 1, the temperature of the air in the ridge duct 4 detected by the temperature sensor 25a is also low. In this case, the backflow prevention damper 6 is a ridge duct 4
The side is closed. In addition, the flow path switching damper 8 closes the exhaust duct 9 side to allow the heat collecting fan 7 to communicate with the falling duct 10.

When sunlight hits the solar cell 22, power is generated,
The storage battery 23 is charged through the control device 20. Storage battery 2
When 3 is charged, the circuit in the control panel is activated.

When the sunlight hits the roof panel 1 and the temperature in the ridge duct 4 exceeds the set temperature, the backflow prevention damper 6 reverses and opens the ridge duct 4 side. Then, the heat collecting fan 7 starts to start collecting heat.

The outdoor air is first introduced by the heat collecting fan 7 from the air inlet 3 such as the eaves into the air passage 2 formed immediately below the roof panel 1, where the roof panel 1 heated by sunlight is heated.
And is collected in the wing duct 4 before entering the handling box 5.

The heated air flows down in the falling duct 10 from the handling box 5, enters the air circulation space 13 between the heat storage soil concrete 11 and the floor panel 12, and directly heats the floor under the floor via the floor panel 12. The heat is stored in the concrete soil for heat storage 11 and the outlet 14
The room temperature gradually rises by performing three types of heating actions, which are directly blown into the room as warm air from the room.

When the hot water is removed, the circulating pump 19 is operated by pressing a dedicated switch on the remote control device 27, and the hot water starts to circulate with the hot water coil 15 via the circulation pipe 16. In the operation of the pump, the solar cell 22 is receiving solar radiation, and the temperature difference between the temperature sensor 25b in the handling box 5 and the temperature sensor 25c in the hot water tank 17 is equal to or higher than a certain temperature. is necessary. This temperature difference is considerable in the morning of the start of hot water collection, but when the heat medium circulates repeatedly in the hot water collecting coil 15, the hot water storage tank 1
The temperature in the inside 7 rises rapidly, and when the temperature difference falls below a certain level, the pump is stopped and the hot water is stopped.

When the room temperature sensed by the thermostat 24 in the room becomes higher than the set temperature, the flow path switching damper 8
Opens the exhaust duct side 9 and the heated air is discarded outdoors. When the temperature falls below the set temperature, the flow path switching damper 8 falls and opens the duct side 10 to perform a heating action.

In the above operation, the heat collecting fan 7, the damper motor and the circulation pump 19 are driven by the solar cell 22 to save energy. In addition, since electric power is also supplied from the solar cell 22 to the control device 20, energy is similarly saved.

In the summer night, there is a difference between the temperature sensor 25e for sensing the outside air temperature and the temperature sensor 25f for sensing the room temperature of a certain temperature or more, and the humidity sensor 26 for sensing the outside air humidity is below the set temperature. Then, the backflow prevention damper 6 opens the ridge duct 4 side, the flow path switching damper 8 connects the heat collecting fan 7 and the falling duct 10 side, and closes the heat collecting fan 7 and the exhaust duct 9 side. .

In this state, when the heat collecting fan 7 of the handling box 5 is turned, the cool air at night enters from the air inlet 3 such as the eaves or the like into the air flow passage 2 formed immediately below the roof plate 1 and radiatively cools there. Is made. After being collected in the ridge duct 4, the person moves to the handling box 5, flows down the falling duct 10 from the handling box 5, and enters the air circulation space 13 between the heat storage slab concrete 11 and the floor panel 12, The cooling operation is performed between the cold storage in the heat storage interstitial concrete 11 and the direct discharge of the cold air from the floor outlet 14 into the room.

As another embodiment, as shown in FIG.
A direct air outlet 41 into the room may be provided near the lower end of the falling duct 10. Although not shown, an opening / closing door may be provided at the outlet 41 so that it can be opened and closed freely.

As still another embodiment, as shown in FIG. 10, the falling duct 10 may not be opened under the floor panel 12, but may be provided only with the direct outlet 41 into the room provided near the lower end.

In the example of FIG. 10, the warm air is blown directly into the room without passing under the floor, so that it is optimal for warming a specific room in a short time.
