Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ventilation duct panel unit, in which a ventilation duct is installed in a building in which a structural surface such as a wall or floor is formed by arranging a plurality of panel units. It can be used when forming.

[Background technology]

2. Description of the Related Art In recent years, prefabricated buildings have been promoted in buildings such as houses, and a living room has been configured by assembling a box-shaped capsule unit, panel unit, or the like in a box shape in advance. 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 the piping through which the high-pressure refrigerant passes is intricate, which necessitates the work by a professional. 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 and the refrigerant pipe to each room for each room, and since the air duct can be easily structured and constructed, it is possible to measure and reduce costs. It will be possible. Also,
Since the air itself is supplied, in addition to air conditioning and dehumidification that are usually performed in an air conditioner, ventilation and air blowing can also be performed.Furthermore, the supplied air is filtered, electrostatic adsorption of dust and the like, sterilization, oxygen and It becomes possible to intensively and efficiently perform advanced air conditioning such as adjustment of components such as carbon dioxide and addition of fragrance.

[Problems to be solved by the device]

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. Further, these connecting works need to be carried out separately after assembling the structures such as walls and floors, and the workability is unavoidably deteriorated. 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.

As a prior art related to the present invention,
No. 57-93735, No. 58-148538 and 1-12903
There is an issue.

An object of the present invention is to provide a ventilation duct panel unit that can be structured and constructed easily, can increase the flow rate, and can form the floor surface of a building.

[Means for solving the problem]

The present invention is a hollow structure that has substantially the same outer shape and strength as a panel unit that is arranged in plural to form a structural surface of a building, forms a floor surface of a building, and has conditioned air flowing in the longitudinal direction inside. A box-shaped body, a contacting surface that can be intimately contacted with another body when the body is arranged on the structural surface, and another body that is formed at a predetermined position on the surface and is in contact with the surface A ventilation duct panel unit in which an opening through which air inside can be mutually passed is provided, and a reinforcing member is divided into two in the width direction inside the main body and extends over the entire length in the longitudinal direction. Is configured.

Here, as the structural surface of the building in which the duct panels of the present invention are arranged, a floor surface formed by arranging a plurality of ordinary panel units can be used.

In addition, when the duct panel is arranged along the ventilation path of the building and is arranged with a normal panel unit to form a structural surface, a close contact surface is formed on the main body so that the duct panels come into close contact with each other. An opening may be provided on the surface of each main body, and the positions of the openings may be made to correspond to each other so that the insides of the main bodies communicate with each other when they are in close contact with each other.

[Action]

In the present invention, the floor is formed by arranging duct panels in combination with an ordinary panel unit in a supporting structure or the like of a predetermined part of the building. At that time, the duct panels are arranged along a predetermined path, the surfaces of the duct panels are brought into close contact with each other in order, and the interiors of the duct panels are made to communicate with each other by the openings provided on the surfaces, so that the interior space of each duct panel body is connected. Is formed, and a ventilation duct is formed. Therefore, since the ventilation ducts are connected at the same time by the floor assembly work using the panels, the construction is simple and the main body of the duct panel becomes an air duct as it is. However, it is possible to increase the air flow rate by maximally utilizing the original cross-sectional shape of the panel unit, thereby achieving the above object.

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.

On the other hand, as shown in FIG. 5, the auxiliary duct panel 32 includes a hollow box-shaped main body 32E whose interior is airtight as in the case of the main duct panel 31 described above. And one opening 32H is formed in the end face plate 31B. However, since the ceiling height of the living room 11 part is higher than that of the corridor 12 part, the thickness of the auxiliary duct panel 32 is made slightly thinner than that of the main duct panel 31.

These sub-duct panels 32 are used for the living room 11 in FIG.

The air filled in the sub-duct panel 32 is supplied into the living room 11 on the first floor through the air outlet 35 formed on the ceiling side of the first floor on the opposite end.

By the way, as shown in FIG. 6, the living room 11 on the second floor and the wall surface 16 of the corridor 12 are also composed of the panel unit 15,
Of these, wall duct panels 33 are respectively arranged in the portions connected to the ends of the duct panels 31, 32. The wall duct panel 33 connects the lower end surface of the main body 33E to each duct panel 31,
Apertures formed in each relevant part, closely attached to the upper surface of 32
The conditioned air is supplied from each of the duct panels 31 and 32 through 33H, and the conditioned air is also supplied to the living room 11 and the corridor 12 on the second floor from the blower port 35 formed in the upper portion.

In addition, in FIG. 5 and FIG. 6, each duct panel
An air volume adjusting mechanism 36 using a blade plate or the like whose opening can be adjusted is arranged in each of the air outlets 35 formed in 31, 32, 33, and is provided in each of the living rooms 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, 33 accommodates a built-in cable 37A inside along the longitudinal direction.
Is connected to a connector 37B arranged on the surface of the back side (the side not exposed to the room at the time of installation) near each opening 31J, 31H, 32H, etc., and each duct panel 31, 32, 33 is assembled to form the duct 30. After connecting as described above, a series of wirings 37 along the duct 30 assembled by sequentially connecting the respective connectors 37B from the outside with a connection cable 37C is formed. With such wiring 37, the centralized air conditioning unit 20 performs centralized control of the air volume adjusting mechanism 36 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 37, the centralized air conditioning unit 20 remote controls are possible.

Returning to FIG. 2, the house 10 of the integrated central air conditioning unit 20
In order to return the air inside, 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 and extends to the stairs 13 part through the floor 17 below the first floor. There is. 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.
From 42, it is possible to suck and collect indoor air near the floor surface 17 on the first floor. Further, the second-floor side pipe 42 is connected to a second-floor side recovery port 44 that is opened on the top riser of the stairs 13.
Indoor air near the second floor 14 can be suctioned and collected from 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 manner, the conditioned air that has been mixed with the desired temperature, humidity and the outside air in advance is supplied from the outlet side 22 of the integrated centralized air conditioning unit 20, and the ventilation duct 30 By blowing out from each air outlet 35 through the main duct panel 31 and the sub-duct panel 32, the air condition inside each living room 11 and the corridor 12 on the first and second floors is adjusted, and the air conditioning of each part in the house 10 is performed.

On the other hand, 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 and second floors is collected on the first floor side, respectively.
Alternatively, the pipes 40, 4 are sucked and collected from the recovery port 44 on the second floor side.
It is returned to the suction side 21 of the integrated centralized air conditioning unit 20 via 1, 42, whereby the air is circulated, sequentially adjusted to 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 36. 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 pipe unit 15 at the time of installing the second floor 14, the respective duct panels 31 and 32 are simultaneously connected, 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.

In particular, compared to the case where a ventilation pipe or the like is separately installed in the panel unit 15 as in the conventional case, the work of inserting each pipe into each unit 15 and the work of connecting the inserted pipes can be collectively omitted. Therefore, the construction efficiency can be significantly improved as the number of steps is reduced.

Further, in the case of a conventional ventilation pipe or the like, there is a high possibility that a connection failure or the like will occur due to performing the connection work in a narrow place in the panel unit 15, but in the present embodiment, the duct panels 31, 3
When the two are arranged, they are communicated with each other through the openings 31H, 31J, 32H, and the connection can be surely performed. In particular, when connecting, use a highly viscous adhesive around the opening 31H etc. to ensure airtightness,
A more reliable connection can be made.

Further, since the box-shaped main bodies 31E and 32E are formed in advance for installation, the work at the time of construction can be further simplified. As the main body 31E, 32E, it is possible to combine the same plate materials as those used for the normal panel unit 15 and to have the external dimensions and strength corresponding to each unit 15, and the structure is simple and the cost is also reduced. it can.

Inside the main bodies 31E, 32E, since the heat insulating material 31K and the like are used for lining, it is possible to maintain the temperature of the passing air to improve the energy efficiency during cooling and heating and prevent dew condensation. It is advantageous for improving durability.

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 11 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, the ventilation duct 30 on the second floor 40 that also serves as the ceiling on the first floor
Since it is placed inside the fan, it is formed in a vertical direction
With 35 and the like, 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 is installed in the 12 parts of the corridor that runs through the house 10.
31 is arranged and the sub-duct panel 32 of each living room 11 is arranged in the crossing direction, so that the sub-duct panel 32 is installed in each living room 11
It can be surely connected to the side surface of the main duct panel 31 at any position inside. Therefore, the ventilation duct
The design flexibility of 30 can be increased, and the air from one central air conditioning unit 20 can be uniformly supplied to each part of the house 10.

Furthermore, a ventilation port 35 is provided on the lower surface of the duct panels 31 and 32 so that air can be blown to each of the living rooms 11 and the corridor 12 on the first floor from the ceiling surface, and the duct panels 31 and 32 have upper portions on the upper surface side of the end portions. By connecting a wall duct panel 33 having a ventilation port 35 to each of the living rooms 11 and the corridor 12 on the second floor from a predetermined height, it is possible to avoid inconveniences such as blowing up from the floor surface 14. You can

In addition, a built-in cable 37A is installed on each duct panel 31, 32, 33.
Also, since a connector 37B is provided and each panel can be connected by a connecting cable 37C in sequence when connecting each panel, a series of wirings 37 along the duct 30 can be installed very easily, and each unit 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 36 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.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and includes the following modifications.

That is, each duct panel 31, 32, 33 may be formed in a box shape having a shape and size corresponding to the normal panel unit 15, and the material, the detailed structure, etc. may be appropriately selected for implementation. .

For example, the heat insulating material 31K and the like provided on the main body 31E and the like may be of an appropriate shape and material for implementation, or may be omitted as appropriate, but in consideration of thermal efficiency during cooling and heating, it is similar to the above-described embodiment. It is preferable to provide an insulating lining.

Further, the mounting nut 31G provided on the main body 31E or the like can be appropriately modified or omitted, and for joining with the panel unit 15 or the like, the joining bolts, hooks or the like used in the normal unit 15 may be used as they are. However, when connecting the respective duct panels 31, 32, 33 in which air is circulated to each other, a strong joint or the like that surely brings the close-contacting surfaces such as the end plate 31B into close contact with each other in order to prevent leakage, Alternatively, it is desirable to take measures such as arranging packing around the opening 31H and the like.

Furthermore, the openings 31H and 31 for communication between the duct panels 31 and 32 are provided.
J, 32H, etc. are formed in advance at appropriate positions on the end plates 31B, 32B and the side plates 31A that are the surfaces for close contact with each other, and when not in use, they may be covered with a blind lid or the like. Duct panel
By making 31,32,33 common, it is possible to simplify the preparatory work and reduce the cost by mass production.

Further, the number of these openings 31H, 31J, 32H and the like may be appropriately selected for implementation, for example, the opening 31H of the connection portion between the main duct panels 31 is not limited to two, and may be one or three or more, Opening 31 at the connecting portion of the main duct panel 31, the sub duct panel 32, or the wall duct panel 33
The number of J, 32H, etc. is not limited to one and may be two or more. Here, generally, if the total area of the openings is increased, the flow path resistance is decreased, but the strength is likely to decrease. On the other hand, if the number of partitioning the opening surface is increased, the strength is increased but the resistance is easily increased. It is desirable that the dimensions, etc., be appropriately set according to the properties, pressure, flow rate, etc. of the air passing through the portion.

Further, the air blow port 35 has openings formed in the respective duct panels 31, 32, 33, and the air blow port 35 and the air volume adjusting mechanism are unitized.
The 36 may be properly installed by separately attaching it, or may be attached to the duct panels 31, 32, 33 in advance when carrying in the site. Here, the blower port 35 is formed by each duct panel 31, 32,
The air volume adjusting mechanism 36 can be appropriately changed or omitted as long as it is an opening portion that blows the air inside the room 33 into each living room 11 or the corridor 12.

Further, the provision of the built-in cable 37A and the connector 37B in each duct panel 31, 32, 33, and the configuration in which these are sequentially connected by the connection cable 37C to form a series of wirings 37 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 above 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 part, and the sub duct panels 32 having the half width and slightly thin are arranged in parallel in the living room 11 part. However, the duct panel forming the ventilation duct 30 is not limited to such a configuration, and it is desirable to appropriately set the duct panel according to the allowable space of the installation position or the air flow rate passing through the portion.

Further, the duct panel of the present invention is not limited to the ventilation duct 30 of the comprehensive air conditioning system that circulates the conditioned air by the air conditioning unit 20 as in the above-mentioned embodiment, and other central ventilation system that performs only ventilation, etc. It can also be used to form ducts in a system for circulating air.

[Effect of device]

As described above, according to the ventilation duct panel unit of the present invention, since the inside of the hollow box-shaped duct panel body is used as a flow path of conditioned air, it is not necessary to separately arrange a ventilation pipe or the like. The structure and construction can be simplified, and the flow passage area can be set to the full cross-sectional shape of the unit, so that the flow rate can be increased. Further, since the main body has substantially the same outer shape and strength as the panel unit constituting the structural surface of the building, and further, the reinforcing member is provided in the inside thereof over the entire length in the longitudinal direction, it is possible to prevent bending in the longitudinal direction. , By this, the floor surface of the building can be configured.
