Description

  The present invention relates to a humidity control container and an air conditioning unit, and more specifically, is a component of a regulated air supply device that feeds air in which characteristic conditions such as temperature and humidity are adjusted to the interior of a building such as a house. It is intended for the air conditioning unit and the humidity control container that constitutes the air conditioning unit.

As a method of ventilation or air supply that supplies fresh air to the interior of a house, outdoor air is temporarily introduced into the underfloor space, and air that has been conditioned or humidity-controlled in the underfloor space is supplied from the underfloor space to the indoor space. The technology to do is known.
The underfloor space is less susceptible to large outdoor temperature changes due to seasonal changes, day / night differences, and differences in solar radiation. Therefore, air adjusted to a temperature range comfortable for the occupant can be supplied by supplying the air kept in the underfloor space for a certain period of time to the indoor space.
Furthermore, a technology has also been proposed in which a storage room containing humidity control material such as shale shale is installed in the underfloor space, and the air in the underfloor space is brought into contact with the humidity control material in the storage room before being supplied to the indoor space. (See Patent Document 1). If air conditioned in a certain humidity range by the humidity conditioner is supplied to the indoor space, a more comfortable humidity environment for the occupant can be realized. It is known that humidity-controlling materials such as sandy shale are excellent in the function of removing odor and VOC (volatile organic compounds) such as formaldehyde in addition to the humidity-controlling function. Even if the air stays in the underfloor space and smells or contains VOCs generated from building materials, it is clean and comfortable when these air is supplied to the indoor space. Become air. It is also effective for sick house measures.
JP 2003-105879 A

Even with the technology of the humidity control material storage chamber described above, if the outdoor or underfloor space is in a high humidity environment, the humidity of the air may not be sufficiently reduced. Also, the odor and VOC removal function may be insufficient.
Increasing the humidity conditioning material storage room or increasing the amount of humidity conditioning material accommodated in the storage room can improve the humidity control function and deodorization function. It will increase.
Furthermore, since the humidity control function and deodorization function by the humidity control material largely depend on the environmental conditions, there is a problem that the performance or function varies greatly depending on the season or day and night.

For example, high-temperature air can contain a large amount of moisture, and even when it is brought into contact with the humidity control material, the moisture may not be sufficiently removed. Since Japan's rainy season is hot and humid, the humidity control function of the humidity control material does not work sufficiently, and air from which moisture has not been sufficiently removed may be supplied to the indoor space. The deodorizing function and the VOC removing function are also affected by the temperature condition as in the case of moisture, and the function may be deteriorated by being affected by the humidity condition.
As a technique for solving such problems of the prior art, some of the applicants of the present patent application have previously proposed the technique disclosed in Japanese Patent Application No. 2004-217411.
In this prior art, an air conditioning chamber in which an inorganic porous humidity conditioning material is accommodated is embedded in the ground of the underfloor space. The air in the underfloor space is supplied to the indoor space after passing through the air conditioning chamber. The temperature of the air passing through the air adjustment chamber is appropriately adjusted by heat transfer from the ground. By adjusting to an appropriate temperature condition, an appropriate humidity control function, deodorization function, and VOC removal function are exhibited. The air conditioning chamber is configured by connecting a plurality of tubular air conditioning units.

  An object of the present invention is to provide an air conditioning unit for use in the above-described prior art regulated air supply apparatus that further improves the air conditioning function and facilitates handling such as transportation and storage.

A humidity control material storage container according to the present invention is a humidity control material storage container that stores an inorganic porous humidity control material that performs an air adjustment function in an air control unit that adjusts air and supplies the air to an indoor space. An air conditioning pipe that accommodates the inorganic porous humidity conditioning material and can be sequentially connected in the length direction, and of the air conditioning pipe, closes both ends of the accommodation location of the inorganic porous humidity conditioning material, and allows ventilation. And a possible vent lid.
The air conditioning unit includes the humidity conditioning material storage container and an inorganic porous humidity conditioning material stored in the humidity conditioning material storage container.
〔Building〕
Applicable to ordinary houses and other buildings. It is suitable for installation in a house where the underfloor space and the indoor space are adjacent. In addition to being applied to the indoor space of the first floor in a one-story house or a multi-storey house, it can also be used for ventilation of indoor spaces on the second floor and above. It is also suitable for relatively small apartment houses, factories and buildings.

The underfloor space is surrounded by a foundation structure such as a cloth foundation. The bottom surface of the underfloor space is a ground surface or a soil concrete layer, an ant-proof layer, a moisture-proof layer, etc. constructed on the ground surface. The upper surface of the underfloor space is the back surface of the floor structure that constitutes the floor surface of the indoor space. Usually, the foundation structure surrounding the underfloor space is provided with a ventilation port for taking in outdoor air. A ventilating gap may be provided between the foundation structure, the floor structure, and the wall structure.
[Supply air supply]
Air adjusted in the under-floor space of the building can be supplied to the indoor space.
It is necessary to supply the indoor space with fresh air having a ventilation amount necessary for the residence. The air supplied to the indoor space can be supplied to the indoor space after being adjusted in the underfloor space. The ventilation of the indoor space can also supply outdoor air to the indoor space without passing through the underfloor space. Ventilation through windows and ventilation openings can be used in combination.

Air conditioning means adjusting the physical properties, chemical properties, components, and the like of air to an appropriate state that is comfortable and useful for the occupants of the indoor space. Conditioned air means air in which these characteristics are appropriately adjusted.
The characteristic conditions to be adjusted include temperature, humidity, odor, VOC, ion amount, and the like. Among these characteristic conditions, at least one characteristic condition is adjusted and supplied to the indoor space. The preferable range or adjustment range of each characteristic condition varies depending on the construction condition, environmental condition, and required performance of the house.
[Regulated air supply device]
The adjusted air supply device functions to adjust air and supply it to the indoor space. It can be installed in the ground of the underfloor space and the underfloor space.

An air inlet opening in the underfloor space, an air conditioning chamber embedded in the ground of the underfloor space, communicating with the inlet and flowing in the air in the underfloor space, and an inorganic porous material housed in the air conditioning chamber and in contact with the air A humidity control material and an indoor air supply opening that opens into the indoor space and supplies the air adjusted in the air adjustment chamber to the indoor space are provided.
A part or all of the conditioned air supply device can be installed not on the ground in the underfloor space but on the ground on the outdoor side outside the foundation structure of the building.
[Introduction port]
It opens to the underfloor space, and the air in the underfloor space can be taken into the adjusted air supply device.

It is desirable to set the arrangement structure of the inlet so that the air flowing into the underfloor space from the outside stays in the underfloor space for a certain period of time and then taken into the inlet. For example, the introduction port can be provided at a position slightly away from the ventilation port that connects the underfloor space and the outdoors. The opening direction of the introduction port can be shifted or directed in the opposite direction with respect to the front direction of the airflow flowing from the ventilation port.
A blower fan for forcibly introducing air can be provided at or near the introduction port. A filter that removes foreign matter, a damper that can be opened and closed, a sensor that detects the temperature, humidity, and speed of air can also be provided. These devices can also be provided in an air conditioning chamber, an indoor air supply port, or an air flow path connecting them.

The air conditioning chamber embedded in the ground and the inlet are connected by a pipe or duct through which air flows.
The introduction port can be opened not in the space under the floor but in the outdoor space outside the building. In this case, air having the same temperature and humidity as the outside is introduced instead of air adjusted to some extent in the underfloor space.
[Air conditioning room]
It can be buried in the ground below the floor. Air communicates with the inlet and flows from the inlet. The inflowing air is sent out with the desired adjustment. An inorganic porous humidity conditioning material is accommodated. The air that has been subjected to the predetermined adjustment in the air adjustment chamber is sent out to the indoor air supply port. The air conditioning chamber has an entrance / exit and a conduit connected to the introduction port and the indoor air supply port.

The whole or a part of the air conditioning room can be embedded in the ground outside the building.
A tubular air conditioning chamber is constructed using an air conditioning unit as a part of the air conditioning chamber that fulfills these functions. For the other air conditioning chamber attachment structures, materials, and shape dimensions, the same technology as the normal air conditioning technology can be applied.
[Air adjustment unit]
The air conditioning unit includes a humidity conditioning material container including an air conditioning tube that has a hollow tubular shape and can be sequentially connected in the length direction, and a ventilation lid that closes both ends of the air conditioning tube and allows ventilation. An inorganic porous humidity conditioning material housed in a housing container.

<Air adjustment pipe>
An inorganic porous humidity conditioning material is accommodated and air to be adjusted is circulated.
The air conditioning pipe material needs to have mechanical strength and durability that can be used by being buried in the ground. It is desirable to have moisture barrier properties and water resistance that prevent moisture and groundwater from entering the interior. It is desirable that the heat transfer between the outside and the inside of the air conditioning pipe is good. Specific examples include synthetic resin materials such as vinyl chloride, metal materials, glass materials, ceramic materials, cement-cured materials, and fiber materials. A composite material or a laminated structure combining a plurality of materials can also be employed.

The cross section of the air conditioning pipe is usually circular, but rectangular, other square, trapezoidal, oval, etc. can also be employed.
The dimensions of the air adjustment pipe are determined by the construction conditions and required performance. For example, the inner diameter is adjusted to the amount of air to be circulated. The larger the inner diameter, the less air flow resistance. The smaller the inner diameter, the larger the heat transfer area with the relative ground. A preferable range is an inner diameter of 50 to 400 mm. More preferably, the inner diameter is 100 to 350 mm. The inner diameter or the outer diameter may change in the length direction of the air adjustment pipe. The thinner the wall of the tube, the better the heat transfer, but the thicker the better the mechanical strength. A preferable wall thickness is 5 to 15 mm. The longer the total length, the better the humidity control action for air, but the equipment becomes large and a large amount of inorganic porous humidity control material is required. A preferred length is 0.5 to 4 m.

The air adjustment pipe may be a straight line or a curved line such as an arc. There may be a case where a straight line and a curve are combined, or a bent portion, a branched portion, or a merging portion is included.
<Connection structure of air adjustment pipe>
As a connection structure for sequentially connecting the air adjustment pipes in the length direction, a connection structure in a normal pipe material or building material can be adopted.
For example, a pipe having the same diameter as a whole can be provided with a diameter-expanded connecting portion having an enlarged inner diameter at one end. The inner diameter of the enlarged diameter connecting portion is matched with the outer diameter on the other end side of the air adjustment pipe. They can be connected to each other by fitting the enlarged diameter connecting portion to the end of another air conditioning pipe.

Instead of the expanded diameter connecting portion, the reduced diameter connecting portion can be provided by reducing the outer diameter at one end, and the end can be connected to the end of another air conditioning pipe.
<Ventilation lid>
Both ends of the air conditioning pipe are closed so that the inorganic porous humidity conditioning material accommodated in the air conditioning pipe does not leak. In addition, air can be circulated in the axial direction of the air adjusting pipe.
The material of the ventilation lid can be selected from the same materials as those of the air conditioning pipe. The same material as the air conditioning pipe may be used, or a different material may be selected. Since a large external force such as the pressure of the ground is not directly applied to the vent lid, a very large mechanical strength is not required. A flexible cloth-like or sheet-like material may be used. In order to perform the reinforcing function of the air adjusting pipe, it is effective to have a certain mechanical strength.

As a means for allowing the ventilation lid to be ventilated, the material of the ventilation lid itself can be made of a breathable material. Breathability can be imparted using a porous material or a fiber material. A knitted fabric or a non-woven fabric can be used. A mesh sheet can also be used.
<Vent hole>
It is also possible to provide air permeability by providing air holes in a material having no air permeability. The ventilation hole is set to an inner diameter such that the inorganic porous humidity conditioning material cannot pass through. Specifically, the inner diameter can be set to 5 to 30 mm. Preferably, the inner diameter is 5 to 20 mm. Ventilation holes with different inner diameters can be mixed. The shape of the vent hole is usually a circle, but an ellipse, an ellipse, a polygon, etc. other than a circle can also be adopted. An elongated slit-shaped vent can also be used. In the case of a slit-shaped air hole, the inner diameter is defined by the inner width dimension.

A large number of vent holes can be arranged on the entire surface of the vent lid. They can be arranged at regular intervals on the front, rear, left and right, arranged in a zigzag pattern, arranged in a radial pattern, or arranged in a spiral pattern. The interval or installation density of the air holes may be constant or may vary depending on the location. For example, the center side of the vent lid can increase the proportion of the vent holes to improve the air flow, and the peripheral side can reduce the vent holes to prevent the inorganic porous humidity control material from falling off. .
<Ventilation lid mounting structure>
The ventilation lid is attached to both ends of the accommodation place of the inorganic porous humidity control material in the air conditioning pipe. The ventilation lid may be permanently fixed to the air adjustment pipe or may be detachable.

For example, after the inorganic porous humidity control material is accommodated in the air adjustment pipe, the ventilation lid may be permanently fixed to the air adjustment pipe. As permanent fixing means, adhesion, thermal fusion, joining with nails or screw nails, etc. can be employed.
It is also possible to integrally mold the air adjusting tube and the one-side vent lid. The inorganic porous humidity conditioning material may be accommodated before attaching the opposite-side vent lid.
If the ventilation lid is detachably attached to the air conditioning pipe, the inorganic porous humidity conditioning material can be easily taken in and out as needed. As the detachable attachment means, there are fitting, engagement, and attachment by a detachable fastener. It can also be attached with adhesive tape.

One side air cover can be permanently fixed to the air adjustment tube, and the other side air cover can be detachably attached.
<Sealing lid>
In addition to the ventilation lid, a sealing lid can be attached to the air adjustment unit.
Until the air conditioning unit is used, it is possible to prevent the fine powder of the inorganic porous humidity conditioning material from falling off or to prevent the inorganic porous humidity conditioning material from absorbing moisture. The hermetic lid should be easily removed during use.
The sealing lid can be configured by using the same material as the ventilation lid so as not to have air permeability. For example, the thing without the ventilation hole of the ventilation lid can be used as a sealing lid.

It can be set as a sealing lid by sticking a sheet with airtightness to both ends of the air adjusting tube, or by sticking a sealing film on the outer surface of the ventilation lid.
The entire air conditioning unit can also be stored in a sealed bag.
<Other structures>
A partition or a guide wall for controlling the air flow can be provided inside the air adjustment pipe.
A member or a structure for transporting the air conditioning tube or supporting it on the ground may be provided on the outer surface of the air conditioning tube.
The air conditioning unit can be used for transportation storage or distribution sales in an individual state. This saves the trouble of separately packaging and handling the air conditioning tube and the inorganic porous humidity conditioning material. It is possible to prevent the inorganic porous humidity conditioner from being altered or deteriorated during transportation and handling, and from being deteriorated in humidity control function and deodorization function.

[Assembly structure of air conditioning unit]
A plurality of air conditioning units are connected in the length direction to form an air conditioning chamber. Tubular air conditioning chambers constructed by connecting air conditioning units can smoothly distribute air, have excellent mechanical strength such as deformation resistance, and have sufficient heat transfer area with the ground, making installation easy It has advantages such as. By connecting the air conditioning unit, the overall structural strength can be increased as compared with an air conditioning chamber composed of only one pipe.
The air conditioning chamber buried in the ground is usually buried so as to extend in a horizontal direction parallel to the ground surface. It may extend in an inclined direction or a vertical portion may exist. If an air adjustment unit having a branch structure or a bent structure is used, an air adjustment chamber having a branch structure or a bent structure can be configured.

A tubular air conditioning chamber can be constructed efficiently and easily simply by connecting an air conditioning unit at the construction site of the regulated air supply device.
In the air conditioning chamber, a sufficient contact distance between the inorganic porous humidity conditioning material and the air is provided in the air conditioning chamber so that the inflowing air can be sufficiently affected by the humidity control effect of the inorganic porous humidity conditioning material. It is desirable to keep it. Specifically, the contact distance between air and the inorganic porous humidity conditioning material can be set to 0.5 to 10 m. However, depending on the flow rate of air, the degree of humidity control may vary even at the same contact distance. In order to sufficiently exert the cooling effect by the ground, it is desirable to set a relatively long contact distance.

It is desirable that the air conditioning chamber is buried at an appropriate depth in the ground so that the heat transfer effect from the ground can be sufficiently received. The deeper the location, the more stable the ground temperature can be used. If the burial position is deep, it takes time for the burial work, and the air flow path from the burial position to the ground surface becomes long. A preferable embedding depth is such that the depth expressed by the difference between the center position in the height direction of the air adjustment chamber and the ground surface is in the range of 0 to 10 m. The ground temperature is stable at around 10m underground.
[Inorganic porous humidity conditioner]
It is housed in an air conditioning chamber and comes into contact with air to provide the intended regulating action.

Basically, the same material as the inorganic porous humidity control material used for performing the humidity control function can be used in a normal ventilation humidity control device or the like. Examples include siliceous shale and silica gel.
As the humidity control material, a grain-shaped humidity control material is easy to use. The shape of the agglomerates can be used as a sphere, polygon, or indefinite shape. An indefinite shape with a corner obtained by pulverizing a rock raw material easily forms a gap between the humidity control materials at the time of use, and the contact efficiency with air is improved. The particle size defined by the maximum delivery diameter can be set in the range of 20 to 80 mm. Preferably, the particle size is 20-50 mm. A block body, a honeycomb body, or the like formed by molding a powdery inorganic porous humidity conditioning material together with a binder or the like can also be used.

[Indoor air inlet]
The air that opens to the indoor space is supplied to the indoor space.
It can also be provided on the floor surface or side wall surface of the indoor space, or on the ceiling surface. Air is sent from the air conditioning chamber to the indoor air supply port through piping and ducts.
A blower fan, an openable / closable damper, and a sensor for detecting the temperature and humidity of air can be provided in the indoor air supply port. The supply air volume can also be controlled by comparing the temperature and humidity information of the indoor space with the temperature and humidity information of the air sent to the indoor air supply port.
[Wind]
The flow of air from the introduction port to the air conditioning chamber and the indoor air supply port can be created by forcibly blowing air with a blower arranged in the path.

A normal ventilation or air conditioning fan can be used as the blower.
The amount of air flow or the air blowing force is determined by the ventilation amount required in the indoor space, the adjustment capacity in the air adjustment chamber, and the like. Usually, it can set to about 50-200 m < ³ > / h ventilation volume.
Ventilation of the indoor space can be performed by combining air passing through the regulated air supply device of the present invention and air sent directly from the underfloor space into the indoor space without passing through the regulated air supply device of the present invention. In the case where temperature adjustment or humidity adjustment by the adjusted air supply device is not particularly required, ventilation without going through the adjusted air supply device can be performed.

The air flow from the introduction port to the air adjustment chamber and the indoor air supply port can be generated by natural convection and wind without performing forced ventilation by the blower provided in the adjusted air supply device. For example, if the air in the indoor space is exhausted outdoors by an exhaust fan provided on the wall surface of the indoor space, the air is sucked into the indoor space from the indoor air supply port accordingly. It can be ventilated by natural ventilation due to the temperature difference between the room and the space under the floor.
[Adjusted air supply method]
Using the adjusted air supply device described above, the air adjusted in the underfloor space of the building can be supplied to the indoor space.

Step (a):
Air in the underfloor space is sent from the introduction port to the indoor space through the air adjustment chamber and the indoor air supply port.
Step (b):
In the middle of the step (a), air is brought into contact with the inorganic porous humidity conditioning material in the air conditioning chamber.
Since the air conditioning chamber is buried in the ground, a temperature difference is generated between the space under the floor. For example, when the outdoor temperature is high, such as in summer or during the day, the temperature in the underfloor space is lower than that in the outdoors, but the temperature of the underfloor space is still affected by the outdoor temperature. However, the ground is not affected by outdoor temperatures. As a result, the temperature of the air conditioning chamber is considerably lower than the temperature of the underfloor space. On the other hand, when the outdoor temperature falls, such as in winter or at night, the temperature in the underfloor space also falls, but becomes higher than the outdoor temperature. The air conditioning chamber in the ground has a lower temperature drop than the underfloor space, and the temperature does not drop much. Compared to the underfloor space, the temperature of the air conditioning chamber is maintained at a considerably high level.

The air in the underfloor space is subjected to the effects of temperature control and humidity control by passing through the air adjustment chamber with little temperature change. For example, in summer, warm air is cooled by passing through an air conditioning chamber. Although the humidity increases with cooling, the inorganic porous humidity conditioner can dehumidify the high-humidity air and supply cold and low-humidity air to the indoor space. Conversely, when the low-humidity air passes through the air conditioning chamber, it is humidified and a humidity control action is performed. In the air conditioning chamber where the temperature is stable, the humidity control action by the inorganic porous humidity control material is performed, so that a stable humidity control action is exhibited with little humidity change.
Of course, the air in contact with the inorganic porous humidity conditioner also receives a deodorizing action and a VOC removing action.

It is desirable that the air in the underfloor space flows from the outside into the underfloor space, stays in the underfloor space for a certain period of time, is subjected to temperature control or humidity control, and then introduced from the introduction port. As a result, the temperature of the air before being introduced into the regulated air supply device is regulated to some extent in the underfloor space. Temperature control and humidity control by the regulated air supply device can be performed more effectively. The air from the outside may be mixed with the air whose temperature has been adjusted to some extent in the underfloor space and enter the inlet.
If the air in the underfloor space repeatedly passes through the air adjustment chamber, the adjustment action can be exerted more strongly. A circulation channel that returns to the inlet side of the air conditioning chamber can be provided in the middle of the channel from the air conditioning chamber to the indoor air supply port.

In the step (b), a difference in function occurs due to a temperature difference between the underfloor space and the air conditioning chamber. The greater the temperature difference between the underfloor space and the air conditioning chamber embedded in the ground, the stronger the moisture release and absorption by cooling or heating the air, and the exchange of moisture between the inorganic porous humidity conditioning material and the air. Is done efficiently. The temperature control action of air also becomes strong. However, since the temperature difference that occurs naturally is used, there is a certain limit and it varies depending on the season and time zone.
The air volume of the air brought into contact with the porous humidity conditioner can be set to 50 to 200 m ³ / h. The smaller the amount of air, the more the air will contact the porous humidity conditioner over a longer period of time and receive a humidity control action. The larger the air volume, the more air can be supplied to the indoor space.

  The higher the humidity of the air flowing into the air conditioning chamber, the greater the amount of moisture removed by the porous humidity conditioning material. In addition, the amount of moisture released from the air that has cooled down due to heat transfer from the ground also increases. The change in humidity before and after air adjustment can be increased.

The air conditioning unit according to the present invention is embedded in the ground of the under-floor space by connecting a necessary number of humidity control containers containing hollow inorganic tubes and containing an inorganic porous humidity control material in the length direction. The air conditioning chamber can be easily configured. Since both ends of the air conditioning pipe containing the inorganic porous humidity conditioning material are closed with ventilation lids, the inorganic porous humidity conditioning material contained inside falls off both in the storage and air conditioning chambers. It will not be placed or biased.
Such a regulated air supply device equipped with an air conditioning chamber has a temperature condition in which the inorganic porous humidity conditioning material and air come into contact with each other in the air conditioning chamber due to the difference in temperature environment between the outdoor space and the underfloor space and the ground. It is adjusted to more preferable conditions for humidity control or deodorization and VOC removal.

In particular, since the inorganic porous humidity conditioning material is evenly arranged in each space defined by the airflow lid of each air conditioning unit constituting the air conditioning chamber, the inorganic porous material is disposed only on one side of the air conditioning chamber. The humidity control material does not harden and harden, and the ventilation resistance does not increase. The air adjustment function of the inorganic porous humidity conditioner existing in the entire air adjustment chamber can be efficiently exhibited.
As a result, it is possible to adjust air in the air adjustment chamber more appropriately without requiring a special device and without greatly increasing the operating cost. The air supplied to the indoor space can be adjusted to a more comfortable and high-quality air by the resident.

<Construction of adjustment air supply device>
A necessary number of air conditioning units 60 are carried into a construction site of the regulated air supply device 20 such as a construction site of a house. The relatively short air conditioning unit 60 can be easily transported by ordinary trucking or the like. Necessary materials such as pipes constituting the introduction pipe part 31 and the discharge pipe part 33 are also carried in.

At the construction site, the air conditioning unit 30 is assembled by connecting the air conditioning unit 60. The air adjustment units 60 can be bonded with an adhesive between the enlarged diameter connecting portion 64 and the end of the adjacent air adjustment pipe 62. When the end of the vent lid 66 is sealed during transportation and storage, the air adjustment pipes 62 are connected to each other after the sealing is released. For example, the air adjustment chamber 30 can be configured by connecting four air adjustment units 60.
If the pipes constituting the introduction pipe portion 31 and the discharge pipe portion 33 are sequentially connected to both ends of the air adjustment chamber 30, the adjusted air supply device 20 is configured.
The air conditioning chamber 30 or the regulated air supply device 20 assembled in this way is embedded in the ground E of the underfloor space 18. The air conditioning chamber 30 may be placed at the bottom of a hole or groove dug in the ground E, and the earth and sand may be backfilled with the upper ends of the introduction pipe portion 31 and the discharge pipe portion 33 extending upward. Dirt concrete can also be placed.

If the upper end of the discharge pipe part 33 is connected to the blower fan 40 attached to the floor structure 12, the construction of the regulated air supply device 20 is completed.
Even if the floor plan of the house or the shape and size of the underfloor space 18 change, it can be easily handled by simply increasing or decreasing the number of air conditioning units 60 to be used. The troublesome work of transporting and handling the inorganic porous humidity conditioning material 50 in a bulked state becomes unnecessary. During transportation and storage, it is possible to prevent the inorganic porous humidity conditioning material 50 from absorbing excessive moisture or saturating the deodorizing function or the VOC function.
When the air conditioning unit 60 is manufactured, a curved or bent tubular air conditioning unit 60 can be manufactured by using an air conditioning tube 62 that is a curved tube or a bent tube. If the straight, curved, and bent tubular air conditioning units 60 carried into the construction site are appropriately combined, not only the regulated air supply device 20 having a simple linear air conditioning chamber 30 but also more complicated. The adjustment air supply device 20 including the air adjustment chamber 30 having a structure curve or a bent portion can also be easily constructed. It becomes possible to arrange the air conditioning chamber 30 by bypassing the pillars and pipes existing in the underfloor space 18.

[Adjusted air supply method]
In FIG. 1, when the blower fan 40 is driven, the air in the underfloor space 18 passes from the introduction port 22 through the introduction pipe unit 31, the air adjustment chamber 30, the discharge pipe unit 33, the blower fan 40, and the indoor air supply port 24. , Supplied to the indoor space 16.
The blower fan 40 may be driven at all times regardless of the season and day and night, or can be driven only when a large amount of fresh air is supplied to the indoor space 16 quickly. Even if the blower fan 40 is not driven, an air flow from the underfloor space 18 to the indoor space 16 through the air adjustment chamber 30 can be generated by natural convection or wind. A damper or a shutter may be provided at the indoor air supply port 24 or the like to cut off or start the supply of air or arbitrarily control it.

[Air adjustment]
The air passing through the air conditioning chamber 30 comes into contact with the inorganic porous humidity conditioning material 50 in the air conditioning unit 60, and various kinds of properties possessed by the inorganic porous humidity conditioning material 50, such as humidity conditioning, deodorizing, and VOC removing. Air that has been subjected to the action and subjected to the target adjustment is sent out to the indoor space 16.
The air adjustment chamber 30 is buried in the ground E. The temperature of the ground E is quite different from the temperature of the underfloor space 18.
For example, the outdoor environment becomes relatively hot during summer and daytime. At this time, since the underfloor space 18 does not receive solar energy directly, the temperature is a little lower than the outdoor environment. The ground E has a lower temperature than the underfloor space 18. The ground E present on the bottom surface of the underfloor space 18 is not warmed by solar radiation and has a huge heat capacity. Therefore, even if the outdoor temperature changes, the temperature of the ground E hardly changes.

In this state, the air sent from the underfloor space 18 to the air conditioning chamber 30 in the ground E is deprived of heat and cooled, and the temperature drops. When the temperature of the air decreases, the relative humidity of the air increases, moisture contained in the air is condensed and easily released from the air, and is easily absorbed by the inorganic porous humidity conditioning material 50. Compared with the state where the temperature does not decrease, the moisture removed by the inorganic porous humidity conditioning material 50 increases, and the air becomes more dry. Specifically, when the air in the underfloor space 18 passes through the air conditioning chamber 30, the temperature decreases to a humidity of 80% or more, and after passing through the air conditioning chamber 30, the humidity is reduced to about 10 from before the passage. % Can also be reduced.
In general, summer in Japan is hot and humid at the same time, so the above-described action can effectively reduce the humidity of the humid air and adjust the indoor space 16 to a comfortable humidity environment. Can do. Since the temperature of the air is also lowered, cold and comfortable air is supplied to the indoor space 16.

Furthermore, when high humidity air as described above is brought into contact with the inorganic porous humidity conditioning material 50, a phenomenon occurs in which a large amount of negative ions are released from the inorganic porous humidity conditioning material 50. This is considered that negative ions are efficiently generated when water particles enter and exit the pores of the inorganic porous humidity conditioning material 50 or when water particles are generated or disappear. Thus, air rich in negative ions can be supplied to the indoor space.
Contrary to the summer and daytime described above, the outdoor environment is relatively low in winter and night. The underfloor space 18 is maintained at a temperature slightly higher than that of the outdoor environment because there is little effect of radiation cooling, the influence of wind, and the like. The ground E remains at a higher temperature than the underfloor space 18.

The air sent from the underfloor space 18 to the air conditioning chamber 30 is efficiently warmed by the heat supplied from the ground E. Since the heated air has a capacity capable of containing moisture, the efficiency of supplying moisture from the inorganic porous humidity conditioning material 50 to the air is improved. More moisture is contained in the air than when the temperature is low.
In general, in winter in Japan, the temperature is low and at the same time dry. The dry low-temperature air is supplied to the indoor space 16 after passing through the air conditioning chamber 30, thereby obtaining a comfortable air environment for the occupant including relatively warm and appropriate humidity. .
As a result, air is allowed to pass through the air conditioning chamber 30 embedded in the ground E as compared with the case where the air is brought into contact with the inorganic porous humidity control material 50 and then supplied to the indoor space 16 only in the underfloor space 18. As a result, it is possible to supply the indoor space 16 with air adjusted to more appropriate environmental conditions such as temperature and humidity.

  The air conditioning unit using the humidity control container of the present invention constitutes an air conditioning chamber of a regulated air supply device installed in the underfloor space of a general house, and the temperature, humidity, smell of the air supplied to the indoor space, VOC, the amount of negative ions, and other characteristic conditions can be adjusted appropriately. It can provide comfortable and high-quality air for residents, and can greatly contribute to the improvement of the living environment.
