Description

Description: TECHNICAL FIELD The present invention relates to a panel unit type ventilation duct, such as a building air conditioning system in which structural surfaces such as walls and floors are formed by arranging a plurality of panel units. Available for

[Background Art] In recent years, prefabricated buildings have been promoted in buildings such as houses,
A living room is configured by assembling a capsule unit, a panel unit, or the like, which is formed in a box shape in advance, into a box shape. Such a prefabricated building is easy to construct and cost-saving, and because each unit is manufactured in advance in the factory with high precision, it has excellent airtightness and soundproofing, and also has high heat insulation, so it can be used for heating and cooling. It can be done efficiently.

On the other hand, with the improvement of the airtightness of the building, the importance of the equipment for air conditioning such as ventilation and heating / cooling of each room is increasing.

Conventionally, an air conditioner is installed in each room as a simple air conditioner, but one indoor unit is shared by multiple indoor units to improve operating efficiency and consolidate the installation space. Centralized air conditioners are also used. However, in an air conditioner that circulates these refrigerants, a space for installing an indoor unit is required for each room, and piping for passing the high-pressure refrigerant is intricate, which requires a professional work. On the other hand, a duct that branches from the integrated centralized air-conditioning unit that integrates various air-conditioning functions to each room of the building is configured, and air that has been conditioned in advance to a predetermined state is supplied to air-condition each room. Have been attempted.

According to such a centralized air-conditioning system that supplies conditioned air, it is possible to omit the indoor unit for each room and the refrigerant pipes that reach each room, and the air duct can be easily structured and constructed, so that the metering and cost reduction can be achieved. It will be possible. Further, since the air itself is supplied, in addition to cooling and heating and dehumidification that are performed in a normal air conditioner, ventilation and air blowing can also be performed together.Furthermore, filtration of the supplied air, electrostatic adsorption of dust and the like, sterilization, It becomes possible to intensively and efficiently perform advanced air conditioning such as adjustment of components such as oxygen and carbon dioxide and addition of fragrance.

[Problems to be Solved by the Invention]

By the way, the branch duct used in the above-mentioned centralized air conditioning system is usually constructed by sequentially connecting pipes. It is desirable that these pipes be embedded in a structure such as a wall or floor of a building so as not to be exposed in the living room and spoil the appearance. Also, considering the flow rate of air in the duct and the flow path resistance, it is necessary to make the flow path cross-sectional area of the pipe large, especially at the base end side where the air distributed to each chamber collectively passes. Required.

However, in a duct using such pipes, each connection work becomes complicated. In addition, these connection work must be performed separately after the assembly of structures such as walls and floors.
Workability is inevitable. Furthermore, since the diameter of the pipe that can be accommodated in the internal space such as the wall or floor is limited, there is a problem that it is necessary to use a plurality of pipes in parallel to increase the cross-sectional area of the flow path.

It is an object of the present invention to provide a panel unit type ventilation duct that is simple in structure and construction and can increase the flow rate.

[Means for Solving the Problems]

The present invention is a ventilation duct formed in a predetermined path in a building structure surface configured by arranging a plurality of panel units, each panel unit along the duct being formed in a hollow box shape. As a duct panel, an opening is formed on each surface that is in close contact with each other when the duct panels are joined, and each duct panel is sequentially connected through this opening to form a series of ducts that can ventilate. It is a duct.

Here, as the structural surface of the building forming the ventilation duct, a floor surface or a wall surface configured by arranging a plurality of panel units can be used.

In addition, as the route of the ventilation duct, a route that requires ventilation in the building may be set as appropriate, and there are multiple routes such as when the air conditioning of multiple living rooms is performed by a central air conditioning unit or the like, or when a central ventilation system is configured. It may be formed as a branch duct that branches off.

In addition, for the duct panel, prepare a box-shaped duct panel that has approximately the same external dimensions and strength as the normal panel unit arranged on the floor or wall that is the structural surface of the building, and The original panel unit may be replaced and arranged, or a normal panel unit arranged in the relevant portion may be processed to form a box-shaped duct panel.

[Action]

In the present invention as described above, an appropriate panel unit and a duct panel are prepared according to a building to be built in advance,
A wall surface or floor surface is formed by arranging these panels in combination at the site. At that time, the duct panels are arranged in the panel unit so as to form a predetermined path, and the surfaces of the duct panels are brought into close contact with each other in sequence.
By communicating the interiors of the interiors with the openings provided on the surface, a series of ducts is formed according to the arrangement of the panel group, and a ventilation duct is configured. Therefore, since the ventilation ducts are connected at the same time by the panel assembling work, the construction is simple, and the box body of the duct panel serves as an air passage as it is, so that it is not necessary to separately provide a pipe or the like. In addition, the structure is simple, and it is possible to increase the air flow rate by maximizing the use of the original cross-sectional shape of the panel unit.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a house 10 of the present embodiment has a plurality of living rooms 11 (shown by thick frame lines in the figure) on the first and second floors, a corridor 12 leading to each room, and connecting the first and second floors. The second-floor floor surface 14 having the stairs 13 and also serving as the first-floor ceiling is formed by arranging a plurality of panel units 15.

Further, an integrated central air conditioning unit 20 is installed along the outer wall in order to perform air conditioning inside the house 10. This unit 20 is configured integrally with a plurality of functional modules that perform heating / cooling, dehumidification, ventilation, air purification, etc., sucking the air in the house 10 from the suction side 21 and adding processing by each module. The air previously conditioned in a desired state is supplied from the outlet side 22 into the house 10.

Further, in order to blow the pre-conditioned air supplied from the integrated centralized air conditioning unit 20 to each living room 11 and the corridor 12, the space of the second floor 14 of the house 10 is used to branch into a plurality of branches. A ventilation duct 30 is configured.

As shown in FIG. 2, the ventilation duct 30 is installed in the air conditioning unit 20.
A plurality of main duct panels 31 connected to the outlet side 22 and sub-duct panels 32 connected to the side surfaces thereof to reach each living room 11.

As shown in FIG. 3, each of these duct panels 31 and 32 is in the form of a box whose interior is airtight, and is combined with another panel unit 15 as shown in FIG. It also serves as a structural material constituting the above, and has substantially the same external dimensions and strength as those of the ordinary panel unit 15 originally arranged in the relevant portion.

The main duct panel 31 has two openings 33 on the end surface,
By being arranged in the portion along the corridor 12 in FIG. 1, the respective end faces are brought into close contact with each other and communicate with each other through the openings 33. Of these, the main duct panel 31 on the air conditioning unit 20 side is connected to the discharge side 22 via the outlet side duct 34, and the conditioned air from the air conditioning unit 20 is supplied and filled in each panel 31. Also, the main duct panel on the other side
An air outlet 35 is formed on the ceiling side of the first floor 31 and the conditioned air inside is supplied into the corridor 12 on the first floor. The ceiling height of the corridor 12 part is slightly lower than that of the living room 11 part, and the thickness of the main duct panel 31 of the part is set to be relatively large.

The auxiliary duct panel 32 has a width half that of the main duct panel 31, and one opening 33 is formed in the end surface. However, since the ceiling height of the living room 11 part is higher than that of the corridor 12 part, the thickness of the sub-duct panel 32 is slightly thinner than the main duct panel 31, and even if the two sub-duct panels 32 are arranged in parallel,
Not equal to 31. These sub-duct panels 32 are arranged in the portion facing the living room 11 in FIG. 1, so that their end surfaces are brought into close contact with the side surfaces of the main duct panel 31. Here, on the side surface of the main duct panel 31, an opening 33 is also formed in a portion where the sub duct panel 32 is in close contact,
The conditioned air filling the inside of the main duct panel 31 is supplied and filled into the sub duct panel 32 through each opening 33. In addition, a ventilation port 35 is formed on the ceiling side of the first floor at the opposite end of the auxiliary duct panel 32, and the conditioned air inside is supplied to the living room 11 on the first floor.

By the way, as shown in FIG. 4, the living room 11 on the second floor and the wall surface 16 of the corridor 12 are also configured by the panel unit 15. Of these, in the portion connected to the end of each duct panel 31, 32,
A wall duct panel 36 is arranged in each case. The wall duct panel 36 has a lower end surface in close contact with the upper surface of each duct panel 31, 32, and conditioned air is supplied from each duct panel 31, 32 through an opening 33 formed in each corresponding portion, and is formed in the upper portion. The conditioned air is also supplied from the ventilation port 35 to the living room 11 and the corridor 12 on the second floor.

In addition, in FIG. 3 and FIG. 4, each duct panel 3
An air volume adjusting mechanism 37 using a blade plate or the like whose opening can be adjusted is arranged in each of the blower ports 35 formed in 1, 32, 36, and is provided in each living room 11 and the corridor 12 on the first and second floors. The blown air volume of the conditioned air supplied can be adjusted individually.

Further, each duct panel 31, 32, 36 accommodates a built-in cable 38A inside along the longitudinal direction, and this cable 38A is provided on the back side (the side not exposed to the room at the time of installation) near each opening 33 and the like. It is connected to the connector 38B arranged on the surface, and after each duct panel 31, 32, 36 is assembled and connected as the duct 30, it is assembled by sequentially connecting each connector 38B from the outside with the connection cable 38C. A series of wires 38 are formed along the duct 30. By such wiring 38, the centralized air conditioning unit 20 performs centralized control of the air volume adjusting mechanism 37 and the like of each part, and by arranging an operation unit or the like in each living room 11 and connecting it to the nearby wiring 38, the centralized air conditioning unit 20 remote controls are possible.

Returning to FIG. 2, in order to return the air inside the house 10 of the integrated centralized air conditioning unit 20, a recovery pipe 40 is connected to the suction side 21 of the air conditioning unit 20, and this pipe 40 is introduced into the house 10. It is extended to the 13th part of the stairs through the floor 17 under the first floor. The recovery pipe 40 is branched into a first floor side pipe 41 and a second floor side pipe 42 at the stairs 13 portion. Of these, the first-floor side pipe 41 is connected to the first-floor side recovery port 43 opened on the riser surface at the bottom of the stairs 13.
It is possible to suck and collect indoor air near the floor surface 17 on the first floor.
In addition, the second-floor side pipe 42 is connected to a second-floor side recovery port 44 that is opened on the uppermost riser surface of the stairs 13, and the room air in the vicinity of the second-floor floor surface 14 can be sucked and recovered from the recovery port 44. The collection ports 43 and 44 on each floor are each provided with a suction air volume adjustment mechanism, and the suction air volume of the air on the first and second floors can be adjusted individually.

In this embodiment configured in this way, the conditioned air that has been previously mixed with the desired temperature, humidity and the outside air from the outlet side 22 of the integrated centralized air conditioning unit 20 is supplied,
By blowing out from each ventilation port 35 through the main duct panel 31 and the sub duct panel 32 of the ventilation duct 30,
The air condition inside each living room 11 and the corridor 12 on the first and second floors is adjusted to air-condition each part in the house 10.

On the other hand, along with the supply of air, the air in each living room 11 is collected in the corridor 12 on each floor through a door, an appropriate ventilation slit, etc., and the air on the first floor and the second floor are respectively on the first floor side recovery port 43 or the second floor side. It is sucked and collected from the collection port 44, and each pipe 40, 41,
It is returned to the suction side 21 of the integrated centralized air conditioning unit 20 via 42, whereby the air is circulated, sequentially conditioned in a predetermined state, and then supplied again to each part in the house 10.

Here, the air-conditioning state from the blower port 35 to each room 11 and the corridor 12 is individually performed by adjusting the amount of air blown out from each blower port 35 by the air flow rate adjusting mechanism 37. Also, when air conditioning is performed only on the first floor and there is no need for the second floor, for example, by adjusting the intake air volume for each floor at the recovery ports 43, 44, switching (so-called zoning, etc.) for each floor can be performed. The air-conditioning state is switched according to.

According to this embodiment, there are the following effects.

That is, by arranging the duct panels 31 and 32 together with the normal panel unit 15 when the second floor 14 is installed, the duct panels 31 and 32 are connected at the same time, and the branch-shaped ventilation duct 30 is formed. It is possible to construct a ventilation path for air conditioning very simply and in a short period of time.

Especially, as compared to the case where a ventilation pipe or the like is separately installed in the panel unit 15 as in the past, each pipe is connected to each unit.
Since the work of inserting into 15 and the work of connecting the inserted pipes can be omitted in a lump, the work efficiency can be greatly improved as the number of processes is reduced.

Further, in a conventional ventilation pipe or the like, there is a high possibility that a connection failure or the like will occur due to performing a connection work in a narrow place in the panel unit 15, but in the present embodiment, the duct panels 31, 32
When they are arranged, they are communicated with each other through the openings 33, so that the connection can be surely made. In particular, when a highly viscous adhesive or the like is used around the opening 33 for connection, airtightness can be secured and more reliable connection can be performed.

Further, by preparing the box-shaped duct panels 31 and 32 in advance for installation, the work at the time of construction can be simplified.

Here, as the duct panels 31 and 32, a plate-shaped member similar to that used for the normal panel unit 15 is combined, and a box-shaped member having an outer dimension and strength corresponding to each unit 15 can be used, and the structure can be used. It is easy and cost can be reduced.

Further, in the main duct panel 31, by making it a box shape having substantially the same external dimensions as the normal panel unit 15, almost all of the cross-sectional shape of this unit 15 can be used as a flow path, and even with the same external shape, the flow rate can be increased. Can be big.

Further, in the auxiliary duct panel 32, the flow rate with respect to the outer shape can be made large, and by making it half the width of the normal panel unit 15, only one side is used as a passage, which is unnecessary in the terminal portion where the flow rate is low. It is possible to prevent the passage from becoming large, or to prevent the flow velocity and the internal pressure from decreasing.

In addition, the main duct panel 31 is placed in the corridor 12 part,
By providing the sub-duct panel 32 that branches into parts with a thickness, the basic air flow rate before branching can be increased, and efficient air distribution can be performed.

Furthermore, since these duct panels 31 and 32 can be replaced with the panel unit 15 as appropriate, by adjusting the number of installations according to the flow rate, pressure, etc. of the relevant part, it is possible to obtain an appropriate amount suitable for the supplied air. The ventilation duct 30 can be formed.

On the other hand, in the present embodiment, when the second floor 14 is installed, the duct panels 31 and 32 interposed between the panel units 15 form the predetermined ventilation duct 30. The internal space of the body can be effectively used.

In particular, since the ventilation duct 30 is arranged inside the second-floor floor surface 14 which also serves as the ceiling on the first floor, the ventilation port 35 formed vertically is provided.
As a result, air can be supplied to the first floor and the second floor all at once, and space efficiency can be further improved.

In addition, the main duct panel 31 is installed in the corridor 12 that runs through the house 10.
Since the sub-duct panel 32 of each living room 11 is arranged in the crossing direction, the sub-duct panel 32 can be securely connected to the side surface of the main duct panel 31 no matter where it is placed in each living room 11. it can. Therefore, the ventilation duct 30
Can increase the degree of freedom in design and can evenly supply the air from one central air conditioning unit 20 to each part of the house 10.

Furthermore, a blower port 35 is provided on the lower surface of the duct panels 31, 32,
Air can be blown to each living room 11 and the corridor 12 on the first floor from the ceiling surface, and a wall duct panel 36 having a blower port 35 at the top is connected to the upper end sides of the end portions of the duct panels 31, 32 to connect the second floor. It is also possible to blow air to each living room 11 and the corridor 12 from a predetermined height, and it is possible to avoid inconveniences such as blowing up from the floor surface 14.

In addition, each blow port 35 can appropriately adjust the blown air volume by the air volume adjustment mechanism 37, and can individually set the air conditioning state in each living room 11 and the corridor 12.

In addition, each duct panel 31, 32, 36 has a built-in cable 38A
And a connector 38B is provided, and each of them is configured so that they can be sequentially connected by the connection cable 38C when connecting each panel, so that a series of wirings 38 along the duct 30 can be installed very easily, and each part from the central air conditioning unit 20 can be installed. In addition to being able to perform centralized control of the air volume adjusting mechanism 37 and the like, it is also possible to easily perform remote control of the centralized air conditioning unit 20 by an operation unit or the like arranged in each living room 11.

In addition, for the ventilation duct 30, a collecting pipe 40 that continues from the stairway 13 part to the central air conditioning unit 20 is provided to collect the air supplied to each living room 11 and the corridor 12 from the stairway 13 part. It is not necessary to install a recovery duct, etc. that continues from 11th. Therefore, the interior of the second-floor floor surface 14 can be used exclusively as the ventilation duct 30, and there is no problem that a plurality of types of ducts are intermingled, and the structure of the house 10 can be simplified and the construction can be facilitated. .

Further, the recovery pipe 40 continuing from the portion of the stairs 13 to the central air conditioning unit 20 is branched into the pipes 41 and 42 on the first floor side and the second floor side, respectively, and the recovery ports 43, 4 at the lower part and the upper part of the stairway 13, respectively.
Since it is configured so that the air on the first floor and the air on the second floor can be collected separately from 4, so-called zoning can be performed,
It is possible to perform efficient air conditioning operation without waste.

The present invention is not limited to the above embodiment,
The following modifications are also included.

That is, each duct panel 31, 32, 36 may be formed in a box shape having a shape and size corresponding to the normal panel unit 15, and its material, detailed structure, etc. may be appropriately selected for implementation. .

For example, the interior of each duct panel 31, 32, 36 may be lined with a heat insulating material to maintain the temperature of the supplied air to improve energy efficiency and prevent dew condensation. Therefore, it is advantageous for improving durability.

Further, when joining the duct panels 31, 32, 36 to each other or the panel unit 15, the joining bolts and hooks used in the normal unit 15 may be used as they are, but the duct panels 31, 32 When connecting 32 and 36, it is desirable to use stronger joints or the like so that they are closely contacted to prevent leakage, or to arrange packing etc. around the opening 33. .

Furthermore, the openings 33 for mutual communication of the duct panels 31, 32, 36 are provided.
May be formed at an appropriate position on each surface, and an opening may be formed on each longitudinal end surface or the side surface of the main duct panel 31.
33 may be formed in advance, and if there is no connection, it may be closed by a blind lid or the like as appropriate, and each duct panel 31, 32, 36
It is possible to simplify the preparatory work and reduce the cost by mass production.

Further, the number of the openings 33 at the connecting portion between the main duct panels 31 is not limited to two, but may be one or three or more, and the main duct panel 31, the sub duct panel 32, or the wall duct panel.
The number of the openings 33 at the connecting portions such as 36 is not limited to one each, and may be two or more. Here, generally, if the total area of the openings 33 is increased, the flow path resistance is decreased, but the strength is likely to decrease, while
If the number of openings 33 is increased and the number of openings is increased, the strength is increased, but resistance is likely to occur, and it is desirable that the number, shape, size, etc. of the openings 33 are appropriately set according to the properties, pressure, flow rate, etc. of passing air.

Further, the air blow port 35 has openings formed in the respective duct panels 31, 32, 36, and the air blow port 35 and the air volume adjusting mechanism 37 are unitized.
May be installed appropriately by, for example, separately mounting them, or may be mounted in advance on each duct panel 31, 32, 36 before carrying on site. Here, the blower port 35 corresponds to each duct panel 31, 32, 36.
The air volume adjusting mechanism 37 can be appropriately changed or omitted as long as it is an opening portion that blows the air inside the room 11 into the living room 11 or the corridor 12.

Further, the provision of the built-in cable 38A and the connector 38B in each duct panel 31, 32, 36, and the configuration in which these are sequentially connected by the connection cable 38C to form a series of wirings 38 are not essential to the present invention, and normal wirings are not necessary. May be adopted, and may be appropriately selected for implementation.

On the other hand, in the embodiment, the main duct panel 31 having the same width as the normal panel unit 15 and slightly thicker is arranged in the corridor 12 portion,
Two duct panels 32 each having a half width and slightly thin width are arranged in parallel in the living room 11 part, but the duct panel forming the ventilation duct 30 is not limited to such a configuration.

For example, the number of the sub duct panel 32 reaching the living room 11 may be one, and it can be applied when maintaining the flow velocity when the branch flow rate is small or when limiting the branch flow rate. In this case, a half-width panel unit may be arranged in parallel with the sub duct panel 32, or two sub duct panels 32 may be arranged in parallel but one of them may not be communicated with the main duct panel 31.

Further, the auxiliary duct panel 32 may have the same width as that of the normal panel unit 15, and when the two ducts arranged in parallel are constantly ventilated as in the above embodiment, the structure and work can be simplified.

Further, the main duct panel 31 and the sub-duct panel 32 may have the same thickness, or the two duct panels such as the main duct panel 31 and the sub-duct panel 32 are not limited to, and other ducts having a width such as 1/3 may be used. Although a panel may be used, it is not essential to the present invention to use various kinds of duct panels having different widths, and a duct panel having a single width is used, and a branching portion is provided with a resistance plate or the like so as to reduce the flow rate. It is desirable to set appropriately so that an appropriate ventilation state can be obtained, such as responding to changes.

By the way, in the above embodiment, the ventilation duct 30 is used to
In order to return the air supplied into the central air conditioning unit 20 to the central air conditioning unit 20, the tip of the recovery pipe 40 is branched into the pipes 41, 42 and the recovery ports 43, 44 to perform zoning on the first floor side and the second floor side. Is not essential, and the air may be sucked out from an appropriate portion of the house 10 at the time of collection.

Further, the ventilation duct of the present invention may be used for such recovery. In this case, it is desirable to use the floor surface of the first floor, the ceiling surface of the second floor, or the wall surface of each floor as the collection side, and separate the ducts on the blower side and the collection side as appropriate to avoid interference between the ventilation passages.

Further, the ventilation duct 30 in the above embodiment is the second floor
The structure is not limited to 14, and may be configured by using the floor surface of the first floor, the ceiling surface of the second floor, or the wall surface of each floor.

Further, the ventilation duct of the present invention is not limited to the comprehensive air conditioning system that circulates the conditioned air by the air conditioning unit 20 as in the above embodiment, but other air such as a central ventilation system that performs only ventilation is circulated. It is also available for the system.

〔The invention's effect〕

As described above, according to the panel unit type ventilation duct of the present invention, since the inside of the box-shaped duct panel is used as a flow path, it is not necessary to separately arrange a ventilation pipe or the like, and the structure and construction are In addition to being simple, the flow passage area can be set to the full cross-sectional shape of the unit, so that the flow rate can be increased.
