[0005]

SUMMARY OF THE INVENTION
The heating method using solar heat in the case of winter shown in Japanese Patent Publication No. 0-200036 absorbs solar heat and air that is higher than the outside air temperature does not blow out directly into the room for heating, so the entire process is indirect heating. It only has the effect of assisting indoor heating. That is, the heating is based on the premise that there is a heater such as a stove in the room. In summer, solar heat is not used at all.

[0006] An object of the present invention is to solve the above-mentioned disadvantages of the prior art. When heating is required in winter, for example, warm air directly warms the floor below the floor, heat is stored in the heat storage body of the concrete slab, and the temperature is reduced. Effective heating can be obtained by performing the three functions of blowing out the air from the air outlet into the room and directly heating, and the hot air obtained by solar heat in both winter and summer when heating is unnecessary is An integrated function box that can always be supplied with hot water at an appropriate temperature, taking into account when solar heat is not available or in consideration of the temperature difference between hot air obtained in winter and summer. An object of the present invention is to provide a solar system house capable of simplifying a mechanism and realizing easy construction by providing a handling box.

[0007]

According to the present invention, in order to achieve the above object, an air flow path is provided along a ridge portion of a roof , the air flow path being provided directly below a roof plate having an end opened as an outside air intake on the underside of an eave.

[0008]

According to the first aspect of the present invention, the metal plate heated by the sunlight warms the outside air entering the air flow path, and the heated air rises along the gradient to form a long collection. Go into the heat box . Then, new air enters the air flow path from the outside air intake and is heated and enters a long heat collection box . Such a long heat collection box collects heated air here ,
Air became charged minute hot flows down the falling duct by handling box fan, fed to the air circulation space under the floor, and to warm the lower direct floor, causing the heat storage body of the concrete slab And direct heating from the warm air outlet into the room.

In the handling box, high-temperature air passes through a heat exchanger. In this heat exchanger, water fed from an injection pipe is heated and stored as hot water in a hot water storage tank via a water pipe. However, if this hot water disturbs the hot air heating, the water supply from the injection pipe is stopped. When the temperature of the hot water stored in the hot water storage tank is not sufficient, the hot water is reheated by the auxiliary hot water supply boiler and then supplied to various places by the hot water supply pipe.

When heating is not required at all in summer or the like, the switching damper is switched, and the exhaust duct communicates with the inlet side of the handling box. As a result, the heated air generated on the roof is discarded outside from the handling box via the exhaust duct. Also in this case, in the handling box, the hot air passes through the heat exchanger, and the water sent from the injection pipe is heated and stored as hot water in the hot water storage tank via the water supply pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory view of a solar system house according to the present invention. A roof 1 serves as a solar heat collecting section A, and a space is secured immediately below a metal plate 2 as a roof plate as a roofing material to reduce a roof gradient. An air flow path 3 is formed, and one end of the air flow path 3 is opened on the underside of the eaves or the like to form an outside air intake 4.

[0013] the lower surface of the air passage 3 is constructed as a heat-insulating layer 5 by heat insulating material such as glass wool, top portion near the roof 1 is a glass plate 6 is provided above the metal plate 2. The temperature of the heat collecting air has a limit on the temperature rise on the heat collecting surface of only the metal plate as a result of heat loss to the outside air through the metal plate at the same time as solar heat is obtained by the metal plate. By further covering the metal plate 2 as a roof plate with the glass plate 6, the rising limit of the temperature of the collected air rises, so that a higher temperature heat collection becomes possible, and the influence of the external wind on the heat collection temperature. Can be reduced.

Along the ridge portion of the roof 1 , the inside is a heat insulating layer 5
Long heat collection box 7 with a semicircular cross section surrounded by
G), and the air passage 3 of the roof 1 is communicated therewith. The long condensing heat box 7 becomes heat collector from the solar heat collector unit A.

The floor 8 serves as a heat storage and heat radiating section B, and has an air flow space 11 between the concrete slab 9 and the finishing floor 10.
The air circulation space 11 has an air outlet 12 into the room C.

In the figure, reference numeral 16 denotes a handling box which is disposed between the long heat collecting box 7 and the falling duct 14 and has a built-in fan 13. The box 16 is provided with a backflow preventing damper 18 at the entrance side where the duct 17 from the ridge duct 7 is connected.
So that the fan 13 is located close to the rear, and the outlet side behind the fan 13 is provided with a part connected to the exhaust duct 19 in addition to the part connected to the falling duct 14, but this part is The inside diameter of the box 16 is a narrowed portion 16a that is gradually reduced.

The space between the expansion portion 16a and the fan 13 is formed as an expansion room 16b, and a falling duct 14 is connected to the lower surface of the expansion room 16b. A partition plate 26 extends from the center of the expansion room 16b to the expansion portion 16a. At the end of the partition, a flow path switching damper 20 was provided.

The flow path switching damper 20 connects the inlet side of the box 16 in which the fan 13 is located to the falling duct 14 or connects the falling duct 14 to the exhaust duct 19 through one of the partitions 26 and the throttle 16a. It has a first blade plate 20a for communication. Further, the flow path switching damper 20 has a second blade plate 20b for connecting or disconnecting the falling duct 14 and the exhaust duct 19 through another section of the partition plate 26. The flow path switching damper 20 is a manual type or an electric type, and an operation handle 20c or a motor for rotating the blades 20a and 20b is provided outside the handling box 16.

The fan 13 may be either a sirocco fan or an axial fan, or a fan whose flow rate can be continuously adjusted by a controller in order to adjust the heat collecting temperature and the heat collecting amount. In the handling box 16, a first heat exchanger 21 is provided between the backflow prevention damper 18 and the fan 13.
The second heat exchangers 22 are respectively provided in sections of the section partitioned by the partition plate 26 in the expanded room 16b, which section connects the fan 13 and the exhaust duct 19, and the heat exchangers 2
Numerals 1 and 22 are hot water storage tanks 2 in a circulation line 23 for water injection pipes and water supply pipes.
4, the hot water storage tank 24 is provided with an auxiliary hot water supply boiler 25 and the like, and is connected to a hot water supply pipe leading to a bath, a washroom, and a kitchen.

Next, usage and operation will be described. When the solar heat is to be actively used in winter or the like, the first blade plate 20a of the switching damper 20 blocks the exhaust duct 19 side, and the second blade plate 20b is And the exhaust duct 19 is disconnected.

When there is daytime sunlight, the metal plate 2 of the roof 1 is heated, and the loss to the outside is reduced in a portion of the glass plate 6, so that the temperature becomes higher and the air immediately below the metal plate 2 is passed through the metal plate 2. The air in the flow path 3 is also warmed, rises along the gradient, and enters the ridge duct 7 as a heat collection box. At the same time, fresh air enters the air flow path 3 from the fresh air inlet 4 and is heated in the same manner.

When the fan 13 is operated, the roof 1 is moved as described above.
Heated air is elongated heat collection volume generated by solar heat collector unit A in
After being collected in the box 7 and having a sufficiently high temperature, it enters the handling box 16 while pushing and opening the damper 18 via the duct 17 to heat the first heat exchanger 21.

Then, it is sent into the air circulation space 11 of the floor 8 via the falling duct 14. The warm air blown into the air circulation space 11 is blown out from the warm air outlet 12 into the room C to perform warm air heating. And the room C always has the fan 13
Hot air is supplied to the room C through doors, windows and gaps between walls.
Although the air may come out, the cold air outside will not enter. Further, the warm air that has entered the air circulation space 11 also performs floor heating in which the floor surface is directly warmed via the finishing floor 10. Furthermore, the concrete slab 9 is warmed and heat is stored here.

On the other hand, the water sent from the injection pipe is heated by the heat exchanger 21 and the hot water is stored as hot water through the water supply pipe.
The hot water is stored in the hot water supply 24 and is reheated directly from the hot water supply boiler 25 to the hot water supply pipe. In addition, there is not enough sunlight in the morning or cloudy weather, and the hot water removal in this heat exchanger 21 lowers the temperature of the hot air passing through the heat exchanger 21 and lowers the temperature of the hot air to the air circulation space 11. If it becomes too much, the water supply from the injection pipe is stopped and hot water is not removed.

By the way, in the solar system house as described above, at night, warm air under the floor falls and the duct 14 rises as a chimney. On a sunny winter night, the roof surface is cooled by sky radiation, and the air in the heat collecting air layer descends on the roof surface. These two powers act as power, causing the air flow opposite to that during heat collection, and when this flow occurs, the humid air under the floor and in the room spills on the cooled roof surface to form condensation. Occurs.

In this case, when the operation of the fan 13 is stopped, the damper 18 is automatically closed, and the circuit of the heat collecting system is closed. As a result, the warm air under the room C and the floor 8 does not escape to the outside, and no new air is supplied to the air passage under the roof, so that dew condensation is also prevented. Further, under the floor 8, the heat radiation from the concrete slab 9 as the heat storage body continues the floor heating.

When no heating is required, such as in summer, the exhaust duct 19 side of the switching damper 20 is communicated with the inlet side of the handling box 16 by the first blade plate 20a. As a result, the heated air generated in the solar heat collecting section A of the roof 1
Simply entering the handling box 16 and making hot water in the heat exchangers 21 and 22, the waste water is discarded from the exhaust duct 19 to the outside. Therefore, in summer, it is used only as a hot water supply system. Since there is a heat exchanger 22 in addition to the heat exchanger 21, hot water can be produced by effectively utilizing solar heat. In addition,
In this case as well, the damper 18 is closed except during heat collection to prevent condensation on the roof surface.

Further, as described above, when the heat is exhausted by the exhaust duct 19, the second duct plate 20 b of the damper 20 is overlapped with the partition plate 26 so that the exhaust duct 19 and the falling duct 14
Can be communicated with. In this way, the air sent directly from the fan 13 to the exhaust duct 19 is
At 16a, the flow velocity increases, and an attractive force is applied to another section of the partition plate 26, that is, a communication portion with the falling duct 14.
As a result, the air in the falling duct 14 is attracted and sent to the exhaust duct 19, so that the air circulation space 11 below the floor 8 can be ventilated.

[0029]

As described above, in the solar system house of the present invention, the warm air directly heats the floor below the floor, the heat is stored in the heat storage of the concrete slab, and the hot air is blown into the room from the hot air outlet. Effective heating can be obtained by performing three types of heating action with direct heating, and hot air obtained by solar heat can be used for hot water removal in both winter and summer when heating is unnecessary, In addition, a handling box, which is an integrated function box, will be provided to ensure that hot water at an appropriate temperature can always be supplied in consideration of the case where solar heat cannot be obtained or the temperature difference between hot air obtained in winter and summer. Thereby, the mechanism can be simplified and the construction can be simplified.
