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, a sunroom is created outside the living room, and this is used as a greenhouse to take warm air from here into the living room. The applicant has previously proposed and applied for a solar system house that promotes this reasonably and can effectively use air collected by sunlight without being limited to the direction. Japanese Patent Application No. 61-311485 (Japanese Patent Application Laid-Open No. 63-165633) and Japanese Patent Application No. 62-234666 (Japanese Patent Application No. 64-75858) are such.

Referring to FIG. 7, an air flow path 2 having a roof slope is formed directly under a roof plate 1, and the lower surface thereof is formed as a heat insulating layer provided with a heat insulating material such as glass wool. One end of the air flow path 2 is opened as an outside air intake 3 in the underside of the eaves or the space behind the hut for ventilation in the hut, and the other end is communicated with a ridge duct 4 as a heat collection box made of a heat insulating material. Near the top of the roof 1, a glass plate 25 was provided above a metal plate.

[0004] The temperature of the heat-collecting air at the roof portion is increased by the temperature rise at the heat-collecting surface of only the roof sheet 1 as a result of heat loss to the outside air through the roof sheet 1 at the same time as the solar heat of the roof sheet 1 is obtained by the metal sheet. Although there is a limit, a glass plate 25
In this case, the rising limit of the temperature of the collected air can be increased, and a higher temperature can be collected, and the influence of the external wind on the collected temperature can be reduced.

[0005] A backflow prevention damper 6, a heat collecting fan 7 and a flow path switching damper 8 are provided, and one of the outflow sides of the flow path switching damper 8 is provided with an exhaust duct 9 to open a handling box 5 which is opened outdoors in an attic space. With
The inflow side of the backflow prevention damper of the handling box 5 is communicated with the ridge duct 4, and a flow path switching damper 8 is provided.
Is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 opens into an air circulation space 13 between the heat storage soil concrete 11 and the floor panel 12, and the air circulation space
An outlet 14 from 13 to the room was provided.

As described above, 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 the backflow prevention damper 6 is opened to the room by a suction port 23 at the ceiling or the like. The backflow prevention damper 6 is also configured as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 22 side. Further, if the room provided with the suction port 23 in which the circulation duct 22 opens is the second floor, the room on the first floor where the floor panel 12 provided with the outlet 14 to the room has a blow-through structure or a staircase room It is desirable to allow air to flow freely, for example.

In the handling box 5, a hot water supply coil 15 is provided between the backflow prevention damper 6 and the heat collection fan 7,
The hot water supply 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 to connect a hot water supply pipe 24 leading to a bath, a washroom, and a kitchen. I do. On the other hand, the pit was dug down into the thermal storage soil concrete 11
20 to form a fan vector as an auxiliary heating device here
Install 21. The heat source coil of the fan vector 21 is connected to a heating-only boiler incorporated in the auxiliary boiler 18.

Next, the method of use will be described. When collecting heat in winter, the backflow prevention damper 6 closes the connection port of the circulation duct 22 and opens the connection port connected to the ridge duct 4. Further, the flow path switching damper 8 closes the exhaust duct connection port, and connects the heat collection fan 7 and the falling duct connection port. The roof plate 1 as a metal plate warms the outside air that has entered the air flow path 2, and the heated air rises along the gradient and is collected in the ridge duct 4, and then enters the handling box 5 by the fan 7 and is handled. It flows down from the box 5 through the falling duct 10 and enters the air circulation space 13 between the heat storage clay concrete 11 and the floor panel 12. In this air circulation space 13, the heated air directly warms under the floor via the floor panel 12, stores heat in the thermal storage clay concrete 11, and is directly blown into the room as warm air from the outlet 14. Performs three heating functions. On the other hand, in the hot water supply coil 15, the water fed from the hot water storage tank 17 through the circulation pipe 16 is heated and stored in the hot water storage tank 17 as hot water, and further from here the auxiliary boiler 18 for additional heating is used as needed. It is reheated and hot water is supplied to various places from the hot water supply pipe.

At the time of non-heat collection such as nighttime, the backflow prevention damper 6 closes the connection port connected to the ridge duct 4 and opens the connection port of the circulation duct 22. If the heat collecting fan 7 is driven in this state, the indoor air enters the handling box 5 from the suction port 23 via the circulation duct 22 and flows down from the handling box 5 into the falling duct 10, and the heat storage soil concrete Enter the air circulation space 13 between 11 and the floor panel 12,
The heat storage soil concrete 11 is heated by the heat radiated, is blown into the room as warm air from the outlet 14, and repeats the circulation entering the inlet 23 again. In this case, hot water is not collected by hot water supply coil 15. In addition, when the amount of heat is insufficient only by the heat release from the heat storage soil concrete 11, the fan vector 21 is operated as an auxiliary heating device.

In a season such as summer when the temperature is high and heating is not required, it is necessary to discharge all the heated air heated by the roof panel 1 to the outside air and discard it. 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 discharged from the handling box 5 through the exhaust duct. Discarded outside through 9. Since the hot air passes through the handling box 5 to heat the hot water supply coil 15, it is ensured that hot water can be obtained by utilizing solar heat even at high temperatures such as in summer.

[0011]

[0005] The recent spread of air conditioning has
Not only is the peak power demand peaking, a major energy policy problem, but it is also creating a heat island in urban areas, creating a vicious circle of increasingly uncooled air conditioning. . Also, conventional cooling is not always healthy for the elderly and the weak.

By the way, in the above-mentioned solar system house, hot water can be obtained by using solar heat in a high temperature period such as summertime when heating is not required, and cooling is not used at all. An object of the present invention is to solve the above-mentioned inconvenience, to perform cooling at a high temperature such as in summer, and to provide a comfortable cooling suitable for environmental protection without using Freon gas, and to use a heating system facility as such a cooling facility. Therefore, an object is to provide a solar system house which is inexpensive and energy saving.

[0013]

According to the present invention, in order to achieve the above object, first, an air passage having a roof gradient is formed immediately below a roof plate, and one end of the air passage is provided as an outside air intake. It is open and the other end communicates with the ridge duct as a heat collection box.Between this ridge duct and the falling duct whose lower end opens into the air circulation space between the thermal storage clay concrete and the floor panel, the ridge duct is opened. A backflow prevention damper, a fan, and a handling box provided with a flow path switching damper for switching between an exhaust duct and a falling duct are interposed, and air is blown into the room from the air circulation space between the heat storage soil concrete and the floor panel. In a solar system house provided with an outlet, between the handling box and the falling duct, a cooling fan, an adsorbent panel filled with an adsorbent, and a radiation coil. A bypass for cooling is provided that passes through an adsorption tower provided with a cooling coil that circulates a refrigerant, and the adsorption tower has a circulation path that connects the air outflow side of the cooling coil and the air inflow side of the adsorbent panel. Secondly, a plurality of adsorption towers are connected in parallel, and a cycle switching damper is provided at the junction of the inflow side and the outflow side. Of these, the location of the cycle switching damper on the inflow side is handling. The inflow side of the box fan and the circulation duct that opens into the room are switchably connected, and the falling duct and the outflow side of the handling box fan can be switched at the cycle switching damper installation point on the outflow side. Thirdly, the gist of the invention is to provide an outlet into a room having a damper in the middle of the falling duct.

[0014]

According to the first aspect of the present invention, when cooling is performed at a high temperature such as in summer, by driving a cooling fan incorporated in the adsorption tower, indoor air is adsorbed from the circulation duct that opens into the room. Enter the tower and pass through the adsorbent panel. In this adsorbent panel, the humid air from the room is dehumidified by the adsorbent by the adsorbing action of the dried adsorbent. At this time, the latent heat of the moisture absorbed by the adsorbent is transferred to the air, but the adsorption heat generated by the adsorption is removed by the cooling coil that circulates the refrigerant with the heat radiation coil that radiates heat. Dry air exits the adsorption tower, flows down the falling duct, passes through the air circulation space between the heat storage clay concrete and the floor panel, is blown out into the room, receives moisture generated in the room, is humidified and cooled, A good cool feeling can be obtained.

Further, a part of the air cooled by the cooling coil is recycled through the circulation path, and the temperature of the adsorbent is kept low to maintain the adsorption efficiency.

According to the second aspect of the present invention, in addition to the above operation, one of the plurality of adsorption towers connected in parallel performs the adsorption operation as described above, while the other one has the desorption operation. Do. In the adsorption tower that performs the desorption operation, the inflow side is connected to the inflow side of the fan of the handling box, and the outflow side is connected to the outflow side of the fan of the handling box, and the roof plate, which is a metal plate, has a roof gradient directly under the roof plate. The outside air that has entered the flow path is warmed to high-temperature, ultra-dry air. This ultra-dry air is collected in the ridge duct and then enters the handling box by a fan, enters the adsorption tower from the handling box, desorbs and dries the wet adsorbent by the action of the adsorbent, and forms the wet air. It is discharged from the exhaust duct connected to this handling box. As a result, the adsorbent of the adsorption tower becomes dry and is ready for the next adsorption.

According to the third aspect of the present invention, an outlet to a room having a damper is provided in the middle of the falling duct so that air cooled by the cooling coil does not pass under the floor as required. Since the air can be blown directly into the room, the cooling efficiency can be further improved.

[0018]

In the explanatory view showing the embodiment, the same reference numerals are given to the same components as those in FIG. 6 showing the conventional example.

That is, an air flow path 2 having a roof gradient is formed immediately below a roof plate 1, and the lower surface thereof is configured as a heat insulating layer provided with a heat insulating material such as glass wool. This air channel 2

An outlet 14 from the air circulation space 13 to the room was provided. In the vicinity of the top of the roof 1, a glass plate 25 is provided above a metal plate.

The inflow side of the backflow prevention damper 6 of the handling box 5 is connected to the ridge duct 4 as described above, and the inflow side of the backflow prevention damper 6 is opened to the room by a suction port 23 at the ceiling or the like. The backflow prevention damper 6 is also configured as a flow path switching damper for switching the flow path between the ridge duct 4 side and the circulation duct 22 side. Further, if the room provided with the suction port 23 in which the circulation duct 22 opens is the second floor, the room on the first floor where the floor panel 12 provided with the outlet 14 to the room has a blow-through structure or a staircase room It is desirable to allow air to flow freely.

Although the above is the same as the conventional example, the present invention relates to an adsorbent panel 30 filled with an adsorbent having a huge surface area, such as silica gel, theodolite, activated carbon, etc., that is, a substance having an infinite number of pores. The adsorption towers 31 and 32, two of which are arranged in a V-shape so that air passes through them, are connected in parallel by connecting the inflow side and the outflow side with ducts.

FIGS. 2 and 3 show the details of the adsorption towers 31 and 32. The adsorbent panel 30 is such that the adsorbent is housed in a flat basket-like container made of a mesh material. They are arranged in a V-shape such that their lower ends are connected, which may be provided with a load sensor 26. Also, this adsorption tower
In 31, 32, the cooling fan 27 was installed above the adsorbent panel 30, and the cooling coil 38 was installed below. The cooling coil 38 and the heat radiating coil 37 disposed inside the well 55 were connected by a circulation pipe 56 for circulating the coolant by a pump 39. Note that the cooling coils 38 are connected to each other, and a cooling water switching valve 57 is provided at the interconnection. Although illustration is omitted,
A cooling tower may be used in place of the well 55, or an air-cooled type that exposes the radiation coil 37 to the outside air may be used.

The adsorption towers 31 and 32 have a circulation path 28 connecting the air outflow side of the cooling coil 38 and the air inflow side of the adsorbent panel 30.
If necessary, a flow rate adjusting damper 29 may be provided in the circulation path 28, or a damper 40 may be provided at the inlets and outlets of the adsorption towers 31 and 32.

A summer / winter switching damper 42 is provided on the inflow side of the heat collecting fan 7 of the handling box 5, the summer / winter switching damper 42 is used as a first damper, and the flow path switching damper 8 is used as a second summer / winter switching. Configure as a damper. At the junction where the cycle switching dampers 33 on the inflow side of the adsorption towers 31 and 32 are disposed, a branching point on the inflow side of the heat collection fan 7 of the handling box 5 and the middle of the circulation duct 22 opening into the room is provided. And the cycle switching damper
Connect switchably at 33.

At the junction where the cycle switching damper 34 on the outflow side of the adsorption towers 31 and 32 is provided, it is possible to switch between the outflow side of the heat collecting fan 7 of the handling box 5 and the middle of the falling duct 10. Connecting.

A hot water supply coil 15 is provided between the heat collecting fan 7 of the handling box 5 and the flow path switching damper 8, and the hot water supply coil 15 is connected to the hot water storage tank 17 by a circulation pipe 43. An auxiliary boiler 18 for heating is attached, and a hot water supply pipe 24 leading to a bath, a washroom, and a kitchen is connected.

An auxiliary heating coil 41 is provided in the handling box 5 between the backflow prevention damper 6 and the fan 7, and the auxiliary heating coil 41 is connected to the auxiliary boiler 18 by a circulation pipe 45. To be connected.

Next, the usage will be described. When cooling is performed at a high temperature in summer or the like, the backflow prevention damper 6 of the handling box 5 connects the inflow side of the handling box 5 to the ridge duct 4 and closes the circulation duct 22 as shown in FIG. Further, the flow path switching damper 8 closes the falling duct 10 side. Further, the adsorption towers 31 and 32 are connected, for example, as shown in the drawing, to the inflow side of the adsorption tower 32 with the inflow side of the heat collecting fan 7 of the handling box 5, and to the inflow side of the adsorption tower 31 into the room. The cycle switching damper 33 is set so as to be connected in the middle, the outflow side of the adsorption tower 32 is connected to the outflow side of the heat collection fan 7 of the handling box 5, and the outflow side of the adsorption tower 31 is in the middle of the falling duct 10. The cycle switching damper 34 is set to connect. In this case, the summer / winter switching damper 42 is closed, and the outflow side of the adsorption tower 32 is connected to the exhaust duct 9 via the handling box 5.

As shown in FIG. 4, the cooling fan 27 built in each of the adsorption towers 31 and 32 is driven. In the adsorption tower 31, room air is sent from the circulation duct 22 that opens into the room, and when passing through the adsorbent panel 30, the humid air from the room is dehumidified by the adsorbing action of the dried adsorbent. .

The phenomenon of adsorption is a phenomenon in which molecules are physically incorporated into a substance having a huge surface area such as an adsorbent, that is, a substance having an infinite number of pores. The molecule jumps out. This is desorption. Water molecules in the air, that is, water vapor, have kinetic energy (latent heat) because they are vigorously moving. When water molecules are adsorbed by the adsorbent and become immobile, the latent heat is released and the air temperature rises. Adsorption-type dehumidifying cooling uses this principle.

FIG. 6 shows changes in the air temperature. The lower left is the movement of the air used for cooling, but the indoor air from the circulation duct 22 was adsorbed by the adsorbent material when the moisture of the moist air was adsorbed by the dried adsorbent as described above. The latent heat of the minute moisture is transferred to the air, and the air temperature rises.

The dehumidified air whose temperature has risen passes through a cooling coil 38 which circulates coolant water with a radiating coil 37 by a pump 39 to lower the temperature to some extent (radiation cooling in FIG. 6).
Although the relative humidity rises slightly with this temperature drop, it is still dry air.

In the adsorption tower 31, some of the air is recycled through the circulation path 28 to maintain the temperature of the adsorbent at a low temperature and maintain the adsorption effect.

Next, the air exits the adsorption tower 31 and flows down the falling duct 10, enters the air circulation space 13 between the thermal storage concrete 11 and the floor panel 12, is blown out from the outlet 14, and is blown out of the room. The humidified water is cooled by humidification by receiving the moisture generated in the step, and a good cooling feeling is obtained. In the middle of the falling duct 10, if an outlet 47 into the room having a damper 46 is provided, the air cooled by the cooling coil 28 is blown directly into the room as necessary without passing under the floor. I can do it.

When a small cooling tower or the like is used without using the well 55, the cooling becomes insufficient. Therefore, it is sufficient to perform humidification cooling by spraying water after leaving the adsorption tower.
Also, the cold air thus obtained flows down the falling duct 10, enters the air circulation space 13 between the heat storage soil concrete 11 and the floor panel 12, is stored in the heat storage soil concrete 11, and There are three types of cooling operations: cooling the room through the panel 12 and blowing out from the outlet 14.

Thus, the adsorbent panel of the adsorption tower 31
In 30, when the entire adsorbent becomes wet, the cycle switching damper 33 is switched so that the inflow side of the adsorption tower 31 is connected to the inflow side of the heat collection fan 7 of the handling box 5, and the outflow side of the adsorption tower 31 is connected. The cycle switching damper 34 is switched so as to be connected to the exhaust duct 9. This causes the adsorption tower 32 to perform the adsorption in turn.

While the adsorption tower 31 is performing adsorption, the adsorption tower 32
Performs desorption. This desorption will be described.
When the cooling fan 27 built in the roof is driven, the roof plate 1 which is a metal plate has an air flow path 2 having a roof gradient just below the roof plate.
Warm the outside air (temperature of about 30 ° C, humidity of about 85%) into high-temperature, ultra-dry air with a temperature of about 80 ° C and a humidity of about 10% or less. The ultra-dry air is collected in the ridge duct 4 and then enters the handling box 5, enters the adsorption tower 32 from the inlet side of the heat collection fan 7 of the handling box 5, and enters the wet adsorbent in the adsorbent panel 30. Is dried by the desorbing action of the adsorbent.

When the wet adsorbent is desorbed and humidified as described above, the ultra-dry air moves on a line having the same enthalpy as shown in FIG. 6, that is, the latent heat is increased and the latent heat is exposed. The temperature is lowered, and the air is discharged from the exhaust duct 9 through the handling box 5 as humid air. As a result, the adsorbent in the adsorbent panel 30 of the adsorption tower 32 becomes dry, and prepares for the next adsorption.

Also in this case, part of the air in the adsorption tower 32 is recycled through the circulation path 28 to enhance the desorption effect.

The air discharged from the exhaust duct 9 is still hot, and the hot water supply coil 15 heats the water sent from the hot water storage tank 17 through the circulation pipe 45, so that the hot water is supplied as hot water. The hot water is further stored in an auxiliary boiler 18 for reheating as needed, and is supplied to various places from a hot water supply pipe 24.

As described above, in this embodiment, two adsorption towers 31 and 32 are used.
The adsorbent panel 30 alternately repeats adsorption and desorption, and the desorbed and dried adsorbent has lost energy by the amount of water, and this lost energy is recovered during adsorption. However, at this time, the heat capacity and the temperature difference of the device are lost. It should be noted that the mutual switching between the adsorption and the desorption of the adsorption towers 31 and 32 is carried out by increasing the weight of the adsorbent as the adsorption progresses.
In the method of detecting, or by providing a temperature sensor in the room, when the adsorbent material becomes wet, it detects that the outlet temperature of the adsorption tower in the adsorption cycle suddenly starts to decrease, and automatically switches, A method in which a humidity sensor is provided in the adsorption tower and the degree of wetness of the adsorbent is sensed can be adopted. Further, it is also possible to simply perform temporal switching by a timer.

As described above, the two adsorption towers 31 and 32 are provided for desorption / desorption.
The adsorption cycle operates alternately at intervals of about every 20 minutes, during which a short (2-3 minutes) intermediate cycle begins. After the completion of the desorption cycle, the cycle switching damper 33 and the cooling water switching valve 57 are switched in advance to discharge the heat remaining in the adsorption tower. After discharging, the cycle switching damper 34 switches to start a new desorption / adsorption cycle. As a result of exhausting room air in this intermediate cycle,
Ventilation takes place at the same time.

Generally, when cooling is required, the weather is often sunny, so that the present invention can rely almost on solar energy. In addition, the power for air transportation such as fan driving is about 0.25 KW, and it is possible to rely on a solar cell.

However, there are days when it is cloudy and sultry. In such a day, the amount of heat collection is insufficient. In such a case, the air for desorption can be obtained with the auxiliary heating coil 41 in the heating state.

FIG. 5 is a flowchart showing the operation when cooling is not performed, the operation during the intermediate period, and the operation during heating. However, since this is almost the same as the conventional example, it will be briefly described below and detailed description will be omitted.

When cooling is not being performed, the summer / winter switching damper 42 separates the adsorption towers 31 and 32 as in the intermediate period, and the heat collecting fan 7 operates to remove hot water from the collected air and exhaust the same.
Thereby, the heat reception of the roof surface is also discharged, and the flow of heat into the room is reduced. When the heat collection is stopped, the space between the roof and the heat collecting surface is closed by the backflow prevention damper 6, and the supply of humidity from the room to the inside of the roof surface is stopped to prevent dew condensation at night.

During winter heating, the summer / winter switching damper 42 and the flow path switching damper 8 close the adsorption towers 31 and 32 and the summer exhaust path, and the heat-collecting air is sent directly below the floor by the heat-collecting fan 7. . Thus, three kinds of heating actions are performed: heat is stored in the heat storage soil concrete 11, warms the room through the floor panel 12, and is blown out from the outlet 14.

When the room temperature is insufficient, the heating-only boiler 44 works to heat. When the room temperature becomes excessive, the hot water supply coil 15 takes hot water first to prevent overheating. When the heat is not collected, the backflow prevention damper 6 opens the indoor circulation path. When the room temperature is insufficient, the room is heated and circulated to maintain the room temperature.
The hot water supply coil 15 and the auxiliary heating coil 41 do not work at the same time.
