BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar system house that uses solar energy by air and a handling box used for the solar system house.

[0002]

2. Description of the Related Art It has long been practiced to open a large opening on the south side of a house to receive a large amount of winter solar radiation and to open a part of it in summer for ventilation. Taking this one step further, it is also practiced to create a solarium outside the living room and use it as a greenhouse to take in warm air from here. The applicant has previously proposed and filed a solar system house that can reasonably promote this and can effectively utilize the air collected by sunlight regardless of the direction. Japanese Patent Application No. 61-311485 (Japanese Patent Laid-Open No. 63-16
5633) and Japanese Patent Application No. 62-234666 (Japanese Patent Laid-Open No. 64-75858).

The outline will be described with reference to FIG. 4. An air passage 2 having a roof slope is formed immediately below a roof plate 1, and one end of this air passage 2 is ventilated to the lower surface of the eaves or the attic. The space is opened as an outside air intake 3, and the other end is communicated with a ridge duct 4 as a heat collecting box made of a heat insulating material.

A backflow prevention damper 6, a fan 7 and a flow path switching damper 8 are provided inside, and one of the outflow sides of the flow path switching damper 8 is provided with a handling box 5 open to the outside by an exhaust duct 9 in the attic space. The inflow side of the backflow prevention damper of the handling box 5 is communicated with the ridge duct 4, and one of the outflow sides 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 was opened to the air circulation space 13 between the heat storage soil concrete 11 and the floor panel 12, and the air outlet 14 from the air circulation space 13 to the room was provided.

Although the inflow side of the backflow prevention damper 6 of the handling box 5 is connected to the ridge duct 4 as described above, the inflow side of the backflow prevention damper 6 is connected to the circulation duct 19 that opens into the room at the ceiling or the like. The backflow prevention damper 6 is configured as a flow path switching damper that switches the flow path between the ridge duct 4 side and the circulation duct 19 side. In addition, a suction port 20 in which the circulation duct 19 opens
If the room to be installed is on the second floor, it is desirable that the room has a blow-through structure so that air can freely flow on the first floor where the floor panel 12 having the air outlet 14 to the room is provided.

In the handling box 5, a hot water coil 15 is provided between the backflow prevention damper 6 and the fan 7, and the hot water coil 15 is connected to the hot water storage tank 1 by a circulation pipe 16.
An auxiliary boiler 18 for reheating is provided in the hot water storage tank 17 in the middle of the hot water storage tank 17, and a hot water supply pipe 21 is connected to a bath, a washroom, or a kitchen.

In this way, the roof plate 1 which is a metal plate heated by sunlight warms the outside air entering the air flow path 2,
This warmed air rises along the roof slope. Then, this heated air is collected in the ridge duct 4 and then enters the handling box 5 by the fan 7, flows down from the handling box 5 in the falling duct 10, and the air circulation between the heat storage soil concrete 11 and the floor panel 12 is performed. Enter space 13. In this air circulation space 13, the heating air directly heats the bottom of the floor through the floor panel 12, the heat storage soil concrete 11 stores heat, and the air is blown directly into the room from the outlet 14 as warm air. There are three ways of heating.

On the other hand, in the hot water removing coil 15, the water sent from the hot water storage tank 17 through the circulation pipe 16 to this is heated and stored in the hot water storage tank 17 as hot water, and from here it is used for additional heating. It is reheated by the auxiliary boiler 18 and hot water is supplied to various places from the hot water supply pipe.

By the way, in a season such as summer when there is no need for heating at a high temperature, it is necessary to discharge all the heated air heated by the roof plate 1 to the outside air and dispose of it. In that case, the flow path switching damper 8 closes one of the outlet ducts 10 that is the outflow side, and opens the other one of the outlet sides, which is the exhaust duct 9, so that the heated air is exhausted from the handling box 5 to the exhaust duct. Abandoned outdoors via 9. The heated air passes through the handling box 5 to remove the hot water coil 1
Since the heating of No. 5 is performed, it is possible to ensure that hot water can be obtained by utilizing solar heat even at high temperatures such as summer.

In such a solar system house utilizing heated air collected by sunlight, it is effective when the amount of solar radiation is sufficient and long, but at night without sunlight or in the morning when sunlight is not strong. There is a risk that the amount of heat will be insufficient and the effect will diminish. Of these, for nighttime, if a sufficient amount of solar radiation is obtained in the daytime, the heat stored in the heat-storing soil concrete 11 is radiated, so that a certain heating effect can be maintained, but this also increases with time. There is no shortage of things.

On the other hand, in the morning or on days when the weather is not good, the heat radiation amount from the heat storage soil concrete 11 decreases and the heat amount becomes insufficient.

Therefore, in JP-A-3-134435, the hot water take-up coil 15 of the handling box 5 is used as a heat exchanger, and hot water heated by a boiler is sent to the heat exchanger and circulated so as to be returned to the boiler again. If so, the heat exchanger generates heat, which causes the air circulated by the fan 7 to be heated and heated as warm air in the room.

[0013]

However, this Japanese Unexamined Patent Application Publication No.
If the heat exchanger is separately used for hot water removal and auxiliary heating as in Japanese Patent Publication No. 134435, the effect is completely opposite. If the pipe is used in accordance with the hot water removal standard, the auxiliary heating efficiency is poor.

On the other hand, if the hot water removing coil and the auxiliary heating coil are separately provided in the handling box 5, a large space is required and the handling box 5 itself becomes large.

An object of the present invention is to eliminate the above-mentioned inconvenience and to ensure that underfloor heating can be continued even when there is not enough sunlight when the heated air collected by sunlight is to be used for heating. However, since the hot water removal coil and the auxiliary heating coil can be housed in the handling box as one dual-purpose coil, it does not take up much space and the handling box does not need to be large in size. The purpose of the present invention is to provide a solar system house and a handling box used for the solar system house, which can use less fins as compared with the case where a coil and an auxiliary heating coil are provided respectively, and thus require less ventilation resistance.

[0016]

In order to achieve the above object, the present invention provides a solar system house in which an air passage having a roof slope is formed immediately below a roof plate, and one end of this air passage has an air intake port. , And the other end is connected to the ridge duct as a heat collecting box, and a handling box containing a fan and a water heating coil is installed in the attic space, and the inflow side of this handling box is connected to the ridge duct, The outflow side is connected to the upper end of the descending duct, the lower end of the descending duct is opened in the air circulation space between the heat storage soil concrete and the floor panel, and an air outlet is provided from the air circulation space to the room. In the solar system house, the coil is connected to the hot water storage tank by circulation piping, and the hot water storage tank is connected to the hot water supply piping leading to the bath, washroom, and kitchen. To provide the auxiliary heating coil in the dring box, the hot water removing coil and the auxiliary heating coil are fin tube type coils, and the hot water removing tube and a heating tube slightly thicker than this hot water removing tube are arranged in parallel on the same fin. The auxiliary heating coil is connected to the heating only boiler, and the heating only boiler is installed in the auxiliary boiler for additional heating provided in the hot water supply pipe from the hot water tank. Also, as a handling box used for a solar system house, it should be installed in an attic space, etc., and it should be connected to the ridge duct as a heat collecting box that communicates with the air flow path formed directly under the roof plate, and outdoors. An end in the air flow space between the open exhaust duct connection and the heat storage soil concrete and floor panel It is a box with a fan installed and a connection port to the falling duct that opens, and a backflow prevention damper that prevents backflow is installed at the connection port of the box to the ridge duct, and the connection port to the exhaust duct is set up. At the connection port to the down duct, a flow path switching damper for switching air supply to both connection ports is provided, and a hot water coil and an auxiliary heating coil are provided before or after the fan,
The hot water removal coil and the auxiliary heating coil are fin-tube type coils, and it is assumed that they are one dual-purpose coil in which the hot water removal tube and a heating tube slightly thicker than this hot water removal tube are arranged in parallel on the same fin. Is the gist.

[0017]

According to the present invention as set forth in claims 1 and 3, when the heated air is not sufficiently collected in the ridge duct in the morning, the boiler for heating is operated to heat the auxiliary heating coil in the handling box. For example, the air that enters the handling box is heated by the auxiliary heating coil to generate heated air, and the heated air is made to flow from the handling box to the air circulation space between the heat storage soil concrete and the floor panel through the falling duct. The heated air directly warms the bottom surface of the floor via the floor panel, and is blown directly into the room as warm air from the air outlet. The same applies to the case where the amount of heat released from the heat stored in the thermal storage clay concrete decreases at night or the like or when the weather is poor.

Moreover, since the hot water removing coil and the auxiliary heating coil can be housed in the handling box as one combined type coil, it does not take up space and the handling box does not need to be large. In addition, the fins can also be used as compared to the case where the hot water removing coil and the auxiliary heating coil are provided, so that the ventilation resistance is small and the load on the fan is also small. Further, since the hot water take-up tube and the heating tube are not used at the same time, it is possible to give one of the unused tubes a heat exchange function like a fin.

According to the second aspect of the present invention, in addition to the above-mentioned function, the heating only boiler which is a heat source of the auxiliary heating coil is an auxiliary boiler for reheating hot water obtained from the hot water coil in the handling box. Since the built-in heating only boiler can be used, it is not necessary to install this heating only boiler in a special place, and the facility can be simplified.

[0020]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a vertical sectional side view showing an outline of a solar system house of the present invention, and FIG. 2 is a vertical sectional side view of a handling box used in the present invention. In FIG. The same reference numerals are attached.

The general outline of the solar system house is the same as the above-mentioned conventional example, and an air flow path 2 having a roof slope is formed immediately below the roof board 1, and one end of this air flow path 2 is located on the lower surface of the eaves or in the attic. Outside air intake 3 in a ventilated backyard space
And the other end is connected to a ridge duct 4 as a heat collecting box made of a heat insulating material, a handling box 5 is installed between the ridge duct 4 and the falling duct 10, and the lower end of the falling duct 10 stores heat. An opening is made in the air circulation space 13 between the soil concrete 11 and the floor panel 12, and an air outlet 14 from the air circulation space 13 to the room is provided.

The details of the handling box 5 are shown in FIG. 2. The handling box 5 is provided with a backflow prevention damper 6, a fan 7 and a flow path switching damper 8, and the inflow side of the backflow prevention damper is communicated with the ridge duct 4. Then, one of the outflow sides of the flow path switching damper 8 is connected to the falling duct 10
It is connected to the upper end of. The flow path switching damper 8 is a rotating plate that axially supports in the width direction between the exhaust duct connection port 35 and the falling duct connection port 36 of the handling box 5. Further, a partition plate 37 for horizontally partitioning the exhaust duct connection port 35 is provided so as to project inward, and one end of the flow path switching damper 8 is brought into contact with the end of the partition plate 37. In this way, when the flow path switching damper 8 closes the inside of the handling box 5 and the falling duct connection port 36, one end of the channel switching damper 8 engages with the partition plate 37 as shown by the dotted line in FIG. Falling duct connection port 36 and exhaust duct connection port 35
Position it so that it communicates with the lower half.

The inflow side of the backflow prevention damper 6 of the handling box 5 is connected to the ridge duct 4, and the inflow side of this backflow prevention damper 6 is also connected to the circulation duct 19 which is opened indoors by a suction port 20 such as a ceiling. The backflow prevention damper 6 is connected and configured as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 19 side.

The hot water removing coil 15 and the auxiliary heating coil 23 are both fin-tube type coils, and the hot water removing tube 15a and the heating tube 23a are arranged in parallel on the same fin 27 to form the hot water removing coil 15 and the auxiliary heating coil 23. Is configured as one dual-purpose coil, and this is housed in the handling box 5. In this case, the heating tube 23a is a tube slightly thicker than the hot water removing tube 15a.

The hot water removing coil 15 is connected to a hot water storage tank 17 by a circulation pipe 16, and an auxiliary boiler 18 for additional heating is provided in the hot water storage tank 17 in the middle of the hot water supply pipe 17 to connect to a bath, a washroom, or a kitchen. 21 is connected. In addition, an auxiliary heating coil 23 is provided between the fan 7 and the flow path switching damper 8, and the auxiliary heating coil 23 is connected by a circulation pipe 26 to a heating-dedicated boiler 24 installed outdoors or the like. This heating-dedicated boiler 24 is the auxiliary boiler 18 for reheating.
It is possible to use a heating-only boiler that is built into the.

Further, the motor of the fan 7 is surrounded and secured by a case 30 which does not hinder the rotation of the blades, and a pipe 31 which communicates with the inner space around the case 30 is provided. Provided. The pipe 31 penetrates the handling box 5 in the vertical direction. In addition,
The case 30 and the pipe 31 may be covered with a heat insulating material or may be formed of a heat insulating material.

Next, temperature control in the solar system house of the present invention will be described. As shown in FIG. 3, a temperature sensor 25a is provided in the ridge duct 4 to detect the heat collecting temperature in the ridge duct, and as a high temperature sensor to detect the heat collecting temperature near the hot water removing coil 15 in the handling box 5. The temperature sensor 25b is provided. Further, temperature sensors 25c and 25d are provided in the room. Of these, the temperature sensor 25c is for setting the room temperature, and the temperature sensor 25d is for setting the temperature of hot water. Further, the hot water storage tank 17 is provided with a temperature sensor 25e as a low temperature sensor corresponding to the temperature sensor 25b as the high temperature sensor.

These temperature sensors 25a to 25e are connected to the control device 28, and the drive motor of the backflow prevention damper 6 of the handling box 5 and the motor of the fan 7,
The pump of the hot water tank 17, the ignition mechanism of the auxiliary boiler 18 and the heating-dedicated boiler 24 are also connected to the control device 28.

In the morning when the sunlight does not hit the roof plate 1, the temperature of the air in the ridge duct 4 sensed by the temperature sensor 25a is low. In this case, the backflow preventing damper 6 opens the circulation duct 22 side and closes the ridge duct 4 side. Further, the flow path switching damper 8 closes the exhaust duct connection port 35 and connects the fan 7 and the falling duct connection port 36 to each other. When the fan 7 is driven in this state, cool air is discharged from the outlet 14 into the room, which has the opposite effect to heating. Therefore, when the temperature sensor 25c is equal to or lower than the set temperature, first, the heating dedicated boiler 24 is ignited to heat the auxiliary heating coil 23. As a result, the air that enters the handling box 5 from the room through the circulation duct 19 is heated by the auxiliary heating coil 23, becomes warm air, and descends the duct 1.
It goes down from 0 and is blown out into the room from the air outlet 14 for heating.

When the sunlight hits the roof plate 1 and the temperature sensor 25a in the ridge duct 4 exceeds the set temperature, the backflow prevention damper 6 is inverted to open the ridge duct 4 side and close the circulation duct 22 side. Then, the fan 7 starts to start collecting heat. Even if this heat collection is started, the auxiliary heating coil 23
Is still heating. However, if the heat collecting air temperature is equal to or higher than the surface temperature of the auxiliary heating coil, the load of the auxiliary heating boiler is virtually eliminated. The temperature sensor 25c automatically stops the heating only boiler 24 via the control device 28 when the room temperature exceeds the set temperature, whereby the auxiliary heating coil 23 is stopped.
Also stops heating in.

The heated air collected in the ridge duct 4 enters the handling box 5, flows down from the handling box 5 into the falling duct 10, and the heat storage soil concrete 1
1 enters the air circulation space 13 between the floor panel 12 and directly heats the floor below the floor through the floor panel 12, stores heat in the heat storage soil concrete 11, and directly blows indoor air as hot air from the outlet 14 The room temperature gradually rises by performing three types of heating actions such as being blown out to, but the hot water is not started yet until the room temperature rises too high.

When the room temperature reaches the set temperature for hot water removal as sensed by the temperature sensor 25d, the pump in the hot water storage tank 17 is activated to start circulating hot water with the hot water removing coil 15 through the circulation pipe 16. In order to operate the pump, it is necessary that the temperature sensor 25b in the handling box 5 and the temperature sensor 25e in the hot water storage tank 17 have a temperature difference equal to or higher than a certain temperature. Although there is a considerable difference in temperature in the morning when the hot water is taken, the temperature inside the hot water tank 17 rises rapidly as the hot water is repeatedly circulated in the hot water coil 15, and the pump stops when the temperature falls below a certain level. , Stop taking hot water.

The heating-dedicated boiler 24 and the auxiliary heating coil 23 are automatically driven when the room temperature sensed by the temperature sensor 25c does not exceed the set temperature.
This auxiliary heating coil 23 is used even at night or in bad weather.
Can be heated by.

When the fan 7 is driven, the fan 7
When the temperature rises, a rising air current is generated in the pipe 31 by a chimney effect, and the motor in the case 30 is cooled by the flow of air flowing through the handling box 5 from below to above.

On the other hand, when heat is collected in a season such as summer when heating is not required, the backflow prevention damper 6 closes the connection port of the circulation duct 19 and opens the connection port connected to the ridge duct 4. Further, the flow path switching damper 8 is connected to the fan 7 and the falling duct connection port 3
6 is closed, and the fan 7 and the exhaust duct connection port 35 are connected. In this state, one end of the backflow prevention damper 6 engages with the locking flange at the end of the partition plate 37 to connect the falling duct connection port 36 and the half of the exhaust duct connection port 35 below the partition plate 37. When the fan 7 is driven in this way, the heated air collected in the ridge duct 4 enters the handling box 5, heats the hot water coil 15 and then flows through the exhaust duct 9 through the exhaust duct connection port 35 to the outside. Be thrown away. At this time, the air thus sent from the fan 7 directly to the exhaust duct 9 gives an attractive force to the falling duct 10, and the air under the floor enters the exhaust duct 9 through the falling duct 10 and the falling duct connection port 36. Since it is sucked in, it is possible to perform ventilation under the floor at the same time.

[0036]

As described above, the solar system house of the present invention and the handling box used therefor do not have sufficient sunlight when the heated air collected by the sunlight is to be taken in and used for heating. Even under the circumstances, the underfloor heating can be surely continued. Moreover, since the auxiliary heating coil is incorporated in the handling box to compensate for the insufficient heat quantity, the system equipment can be effectively used without taking up space.

Further, since the hot water removing coil and the auxiliary heating coil are housed in the handling box as one combined type coil, the handling box does not have to be large-sized, and the hot water removing coil and the auxiliary heating coil are not required. The fins can also be used as compared to the case where each is provided, so there is less ventilation resistance, and the fan load is also smaller. Moreover, since the hot water take-up tube and the heating tube are not used at the same time, it is possible to give one of the unused tubes a heat exchange function like a fin.
