DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple triple-membrane building which can be widely used as an artificial cultivation house for plants such as horticulture or a temporary hut such as a work place or an exhibition place.

[0002]

2. Description of the Related Art As a building having a simple structure of this type, for example, an artificial cultivation house for plants such as vegetables, fruits and flowers is typical, and it is well known as a plastic house (pipe house). Ideally, this type of building should be easy to assemble, easy to remove, and keep the temperature and humidity inside the building constant throughout the year, with little dependence on the external climate.

For example, JP-A-6-209658 discloses a pipe house having a double membrane structure as a winter cultivation method. This is done by setting up a small vinyl tunnel surrounding a nursery in a large pipe house (plastic house), burying a carbon-based surface heating element in the soil inside the small vinyl tunnel, and air conditioning inside the small tunnel pipe above the soil. And install a surface heating element for far infrared radiation,
This is suitable for plant cultivation in the winter period (prior art 1).

Japanese Patent Application Laid-Open No. Hei 5-308859 discloses, as an air conditioner for an agricultural cultivation house, a night cooling curtain (tunnel-shaped partition) provided in a vinyl house via rails so as to be able to expand and contract. Air conditioner that sends conditioned air through a duct into the night cooling curtain inside the greenhouse, that is, both cooling and dehumidification functions that are effective for growing crops in the greenhouse are adjusted. A configuration provided with a possible air conditioner is disclosed (prior art 2).

[0005] On the other hand, Japanese Patent Application Laid-Open No. Hei 9-144382 discloses that a ship is repaired, painted, constructed on a construction site, a temporary exhibit, a ballpark, etc. In order to be able to work, a lightweight air-injection type rain dust guard air membrane roof with a double membrane structure with a number of perforated ribs forming a rib-like hoje film between the top and bottom membranes It is disclosed (prior art 3).

[0006]

In the prior art 1 described above, the pipe house as a roof and the small vinyl tunnel inside the pipe house have a double membrane structure. It is not a self-supporting structure, and requires a large amount of aggregates and struts, such as iron pipes, to cover each with a film of vinyl chloride, etc. It takes time, the handling is complicated, and the construction cost is high.

[0007] Although an intermediate air layer exists between the greenhouse and the small vinyl tunnel, there is no air conditioner for blowing fresh air into the intermediate air layer and the small vinyl tunnel. It is not enough to maintain proper air conditioning.

In the prior art 2, a double-film structure in which a night cooling curtain is provided in a greenhouse is used. However, as in the above-mentioned prior art 1, the structure is not self-supporting by air pressure, but is an aggregate such as an iron pipe or a column. It requires a lot of materials, and assembling and installing as a building, dismantling, removing and transporting is troublesome and takes a lot of time,
Handling is complicated and construction costs are high.

Although an air layer exists between the greenhouse and the night cooling curtain, conditioned air is directly blown into the night cooling curtain via a duct by an air conditioner. The temperature difference between the part close to the wall and the part close to the wall becomes large, and there is no uniformity, which is insufficient to maintain proper air conditioning for growing crops.

On the other hand, the lightweight air-injection type rain dust guard air film roof according to the prior art 3 is entirely self-supported by the air pressure by injecting air between the upper surface film and the lower surface film. Since it is equipped with a roof, it can maintain the strength as a roof, and it does not require aggregates or supports such as iron pipes, so it is easy to assemble, install, remove and transport, but when it is converted as it is as a greenhouse for plant cultivation etc. In addition, the lower surface film has poor air permeability, so that air cannot be injected into the building, and there is no air conditioner for controlling temperature and humidity, and the internal air conditioning is insufficient.

In each of the above-mentioned prior arts 1 to 3, since a double-layered structure and an air layer exist between them, a certain degree of heat insulating effect can be obtained and the influence of external climate or the like is very small. Air conditioning inside the building is possible without
There are insufficient points such as the influence of sunlight and measures against heat intrusion from the outside due to weather conditions, so that appropriate air conditioning and energy saving effects cannot be expected so much.

The present invention has been made in view of the above circumstances,
Its purpose is to be able to maintain moderate strength as a building independently by air pressure blown from air conditioning equipment,
Aggregates and struts such as iron pipes are unnecessary or small,
To provide a simple building with a triple membrane structure that is easy to assemble, install, remove and transport as a building, has low construction costs, has excellent heat insulation from the outside, and is always blown with fresh air and can be properly air-conditioned. is there.

Also, the air-conditioning inside the building can always be maintained in a proper state with a small amount of energy, and is excellent in heat insulation, is little affected by sunlight, and is hardly affected by changes in the climate. It is an object of the present invention to provide a simple triple-membrane building that is optimal for a house or the like, is very energy-saving, and can reduce costs.

[0014]

According to the present invention, first, a part or all of the peripheral surface of a building is formed of a triple layer comprising an air-permeable inner membrane, an air-impermeable intermediate membrane and an outer membrane, respectively. As a membrane structure, an inner air chamber between these inner membranes and the intermediate membrane,
A configuration in which an outer air chamber is formed between the intermediate film and the outer film, and required air can be blown into the inner air chamber and the outer air chamber from the air conditioning equipment so that the triple film becomes independent by air pressure. This is a simple building having a triple membrane structure.

That is, the triple membrane becomes independent by the air blown from the air conditioner into each of the air chambers between the inner membrane, the intermediate membrane, and the outer membrane, so that an appropriate strength as a building can be maintained. Almost no steel frames or columns are required, and assembly and installation, removal and removal, transportation, etc. are easy, and construction costs can be reduced.

Further, since the air conditioner has a triple membrane structure in which air chambers into which air is blown from the air conditioning equipment are provided, the heat insulation with the outside is excellent, and the air conditioning in the building is hardly influenced by changes in climate or the like. It can always be maintained in an appropriate state with a small amount of energy, and is most suitable as a greenhouse for plant cultivation and the like.

Second, in the first invention, the inner air chamber and the outer air chamber are formed by providing a plurality of reinforcing ribs between the inner film and the intermediate film and between the intermediate film and the outer film. Each of the compartments is divided into a plurality of compartments, and the compartments of the inside air compartment and the compartments of the outside air compartment are each provided with a blow duct for blowing required air from the air conditioner. This is a simple building having a triple membrane structure, wherein an exhaust duct for discharging air is provided.

With such a configuration, since the reinforcing ribs are interposed between the triple membranes, the self-standing strength of the building is further improved, and the air conditioning in the building can be made more uniform, so that the plant can be grown. Proper air conditioning can be maintained.

Third, in the first or second invention,
This is a simplified triple membrane structure building, wherein the intermediate film and the outer film are heat insulating films.

As a result, the heat insulation with the outside is further improved, and the air conditioning in the building can be always maintained in an appropriate state with less energy, without being largely influenced by changes in the climate. The energy saving type can reduce expenses.

Fourthly, in any one of the first to third inventions, the air conditioner may further comprise a blower for blowing outside air into the outside air chamber, and an amount of outside air and air discharged from the outside air chamber as required. Air conditioner that takes in air as air conditioning air, blows the air as conditioned air of the required temperature and humidity into the inner air chamber, passes through the inner membrane, and sends it into the building, and uses discharged from the building A simple structure having a triple membrane structure, comprising: a heat exchanger that conducts the conditioned air as needed and exchanges heat with air-conditioning air taken in by the air conditioner.

[0022] This makes it possible to effectively use the invasion heat from the outside such as sunlight and the heat energy of the used conditioned air exhausted from the building depending on the set environmental condition and the weather condition in the building. , Energy saving can be realized.

Fifthly, in any one of the first to fourth aspects of the present invention, there is provided a simple triple membrane structure building, wherein the intermediate film is an infrared shielding film and the outer film is a light transmitting film. .

This makes it possible to perform air-conditioning with less influence of sunlight on the building, thereby reducing cooling energy which is dominant in the southern part of the southeastern and southern regions, thereby realizing further energy saving.

The air conditioner includes a blower 21, an air conditioner 22, and a heat exchanger 23.

The blower 21 has a blower duct 24 connected to the blow ducts 12 on both sides of the outer air chamber 8, and takes in outside air and sends the building 1 from the blow duct 12.
Are blown into the respective compartments 8a of the outside air chamber 8 from both sides. In addition, each compartment 8 of the outer air chamber 8

The air conditioner (air conditioner) 22 has a suction duct 26 connected to the heat exchanger 23 and a blowing duct 27 connected to the air blowing ducts 11 on both sides of the inner air chamber 7. Have.

The air conditioner 22 uses the fresh outside air in the atmosphere and the exhaust air which is conducted from the outside air chamber 8 as required through the exhaust duct 13 and the conduction duct 25 as heat for air conditioning. Exchanger 23 and suction duct 26
The conditioned air is converted into conditioned air of a required temperature and humidity, and the conditioned air is supplied from the ventilation duct 27 through the air blowing duct 11 to each of the compartments 7a of the inner air chamber 7 of the building 1. Into both sides.

The conditioned air blown into each of the compartments 7a of the inner air chamber 7 forms an air layer sufficient to make the inner film 3 and the intermediate film 4 independent, that is, maintains the air pressure (positive pressure). While passing through the inner membrane 3 (air-permeable membrane) as shown by the arrow, the air is sent into the building 1a from substantially the entire area of the membrane 3, and the building 1a is uniformly air-conditioned.

The conditioned air that has air-conditioned the building 1a is discharged from the outlet 6a of the wall 6 on the back of the building 1 by a ventilation device (not shown).

The heat exchanger 23 is connected to the air conditioner 2 as described above.

At the same time as the outlet 6a
The used conditioned air discharged through the circulating air is conducted through the conducting duct 28 as needed, and heat is exchanged between the used conditioned air and the air-conditioning air.

The triple membrane constituting the covering 2 of the building 1, that is, the inner membrane 3, the intermediate membrane 4, and the outer membrane 5 will be described in more detail. First, the inner membrane 3 needs to be air-permeable. is there. Its air permeability is 0.1 to 10 cc / sec / cm ³
Something is good. The appropriate air permeability is appropriately selected from the self-sustainability of the inner film 3 and the intermediate film 4 and the air flow required for air conditioning. Although the air-permeable film 3 constitutes most of the ceiling surface and both side surfaces of the convex arc-shaped coating 2, the air-impermeable film portion may be partially present.

The inner film 3 is desirably heat conductive.
In addition, infrared shielding properties are desirable. As an example of this film material,
A base fabric made of a woven or knitted fabric such as flame-retardant nylon or polyester and processed with a resin in order to obtain an appropriate air permeability is used.

The intermediate film 4 needs to be air-impermeable. However, leakage of less than about 0.1 cc / sec / cm ³ is acceptable. It is desirable that the intermediate film 4 has a high heat insulating property so that vegetables, fruits, flowers and the like can be artificially cultivated with appropriate conditioned air regardless of day and night of the year.
Since cooling is often performed except during the winter season, it is desirable to use an infrared opaque (blocking) or reflective film that blocks infrared rays that irregularly affect the conditioned air.

As an example of the film material of the intermediate film 4, a woven or knitted fabric such as flame-retardant nylon or polyester is used as a base cloth.
In order to impart the above-mentioned characteristics, a sheet which has been subjected to resin processing such as a vinyl chloride resin or has been subjected to an infrared shielding treatment is used.

The outer film 5 needs to be air-impermeable and heat-insulating, like the intermediate film 4. In general, the building 1 is often provided outdoors,
The outer membrane 5 is preferably a membrane that can be used without being affected by weather such as rain throughout the year, that is, a weather-resistant membrane that is impermeable to water and can withstand various weather conditions. In addition, a light-transmitting film that can absorb the heat of sunlight into the outer air chamber 8a is preferable.

As the film material of the outer film 5, a material made of a woven or knitted fabric such as flame-retardant nylon or polyester and subjected to a resin processing such as a vinyl chloride resin in order to impart the above-mentioned properties is used. it can.

Further, the triple membranes 3, 4, and 5 are desirably made of a transparent or translucent membrane material so that visible light useful for photosynthesis of plants artificially cultivated in the building 1a is easily transmitted. .

The operation of the simple building having a triple membrane structure according to the above-described embodiment will now be described. By the action of the blower 21 and the air conditioner 22 of the air conditioner 20, required air is supplied to the inner air chamber 7 between the inner membrane 3 and the intermediate membrane 4, and the outer air chamber 8 between the intermediate membrane 4 and the outer membrane 5. The air pressure causes the triple membranes 3, 4, and 5 to stand on their own, and the cover 2 becomes a convex arc,
The front and rear walls 6 are also stretched, so that the whole building 1 has a hollow-cave-like shape, and the conditioned air sent to the inside air chamber 7 is transmitted through the inside membrane 3 and sent into the building 1a. Air conditioning of the indoor 1a is performed.

That is, it is possible to assemble and install without using a steel frame or a pillar, and to maintain a proper strength as the building 1, to easily remove, remove, transport, etc., and the construction cost is reduced. Will be cheaper.

Also, since the air conditioner has a triple membrane structure in which air chambers 7 and 8 into which air is blown from the air conditioner 20 are excellent in heat insulation with the outside, and are hardly influenced by changes in the outside climate and the like. Since the conditioned air is supplied to the building 1a through substantially the entire surface of the air-permeable inner membrane 3, the entire building 1a is uniformly air-conditioned.
The air-conditioning system can always maintain the proper condition with little energy, and is most suitable as a greenhouse for plant cultivation and so on.

A plurality of reinforcing ribs 9 and 10 are provided between the inner film 3 and the intermediate film 4 and between the intermediate film 4 and the outer film 5 so that the inner air chamber 7 and the outer air chamber 8 are respectively formed. Since the required air is blown into the plurality of compartments 7a and 8a from the air conditioner 20 through the blow ducts 11 and 12 into the compartments 7a and 8a, the self-standing strength of the building 1 is further improved. At the same time, the air conditioning of the building 1a can be made more uniform, and appropriate air conditioning for growing crops can be maintained.

Further, since the intermediate film 4 and the outer film 5 are heat-insulating films, the heat insulation with the outside is further improved, and the air-conditioning of the building 1a is furthermore hardly affected by changes in climate and the like. It can always be maintained in a proper state with little energy, and it is possible to save money by using a very energy-saving type.

On the other hand, the air conditioning equipment 20 (blower 21
And the air conditioner 22 and the heat exchanger 23), the fresh air and the air discharged from the outside air chamber 8 are taken into the air conditioner 22 as air conditioning air as needed, and the air in the building as conditioned air. The used conditioned air sent into the building 1a or discharged from the building 1a can be conducted to the heat exchanger 23 as needed to exchange heat with the air-conditioning air taken in by the air conditioner 22. 1a, the effective use of invasion heat from the outside such as sunlight,
The heat energy of the used conditioned air discharged from the building 1a can be effectively used, and the energy consumption can be further reduced and the energy consumption can be reduced.

In addition, the inner film 3 and the intermediate film 4 are composed of an infrared shielding film, and the outer film 5 is composed of a light transmitting film. . In other words, since the building 1a blocks infrared rays that irregularly affect the temperature of the conditioned air, such as a rise in the temperature of the conditioned air, air conditioning that is less affected by sunlight during cooling, such as in summer, becomes possible.
An increase in energy consumption can be prevented, and further energy saving can be realized.

On the other hand, sunlight other than infrared rays that have passed through the intermediate film 4 from the outer film 5 also penetrates the inner film 3 and illuminates the building interior 1a. This light is necessary for photosynthesis of plants grown in the building 1a. When the illuminance is insufficient, the light is supplemented by an electric light or the like, but the power is reduced by the amount of the transmitted sunlight.

For example, when the outside air temperature is high in the summer,
When the cooling of a is required, the daytime sunlight passes through the outer membrane 5 and enters the outer air chamber 8, but since the intermediate membrane 4 is an infrared shielding or reflecting property, The air in the outer air chamber 8 cannot be permeated and is heated. The warmed air is conducted from the exhaust duct 13 to the heat exchanger 23 through the conduction duct 25, but is not used as air for air conditioning or heat exchange because it is higher than the required air conditioning temperature of the building 1a. Discharge as it is. That is, the air in the outer air chamber 8 acts as a heat insulating layer for maintaining the cooling state in the building.

The outside air in the atmosphere, which is lower in temperature than the air discharged from the outside air chamber 8, is taken into the air conditioner 22 from the heat exchanger 23 through the suction duct 26. The air inside the air chamber 7 is conditioned as humidity-conditioned air from the ventilation duct 27 through the air blowing duct 11.
And is supplied to the building 1a through the inner membrane 3 to air-condition (cool) the building 1a.

Since the used air-conditioned air in the building 1a is in a low temperature state to some extent, it flows from the exhaust port 6a to the heat exchanger 23 through the conduction duct 28, where the air-conditioner 22
Exchanges heat with the outside air taken in as air conditioning air. As a result, the outside air whose temperature has been lowered to some extent is further air-conditioned (cooled) to a predetermined temperature and humidity by the air conditioner 22, and supplied from the inside air chamber 7 to the building 1a as described above. That is, the thermal energy of the used air-conditioned air in the indoor 1a in the low temperature state can be effectively used.

When the outside temperature is low in winter or the like and the building 1a needs to be heated, the infrared rays of the solar rays transmitted through the outer membrane 5 and incident on the outer air chamber 8 cannot pass through the intermediate membrane 4 as described above. The air in the outer air chamber 8 remains in the outer air chamber 8 and is heated by the heat transfer. The warmed air is discharged from the discharge duct 13. Since the discharged air is higher in temperature than the outside air and close to the required air-conditioning temperature of the building 1a,
The air is conducted to the heat exchanger 23 through the conduction duct 25, and the discharged air and fresh outside air taken in from the atmosphere are mixed by a required amount, and are taken into the air conditioner 22 as air conditioning air.

Thus, the air for air conditioning, which has been heated in advance, is further conditioned by the air conditioner 22 to the required temperature and humidity to be conditioned air, and is supplied from the ventilation duct 27 to the inside air chamber 7 via the air blowing duct 11. The pressure is sent, and from there, it passes through the inner membrane 3 and is supplied to the building interior 1a, and the building 1a is air-conditioned (heated to a required temperature).

According to the above-described embodiment, the conditioned air of the building 1a is always used for artificial cultivation of vegetables, fruits, flowers, etc., in response to external changes such as temperature and solar radiation regardless of the season or day and night of the year. It can be maintained in a proper state.

[0063]

As described above, the simple triple-structure building of the present invention can stand alone by the air pressure blown from the air-conditioning equipment and can maintain an appropriate strength as a building, and can be used for aggregates such as iron pipes. The pillars are unnecessary or small, and the building is easy to assemble, install and remove / transport, and the construction cost is low. In addition, it is excellent in heat insulation with the outside, and fresh air is always blown into it so that appropriate air conditioning is possible.

Also, the air-conditioning inside the building can always be maintained in an appropriate state with little energy, with excellent heat insulation, little influence of sunlight, little influence of external changes such as climate throughout the year, and little energy. Ideal for greenhouses for cultivation, etc., it is a very energy-saving type and can save money.
