Description

The present invention relates to an air supply chamber installed in a linear outlet for supplying conditioned air into a room, and a structure of the linear outlet using the air supply chamber.

In various buildings such as office buildings, commercial facilities, and medical facilities, when installing air-conditioned air outlets in rooms such as living rooms and corridors, elongated outlets called linear outlets are installed on the ceiling. In some cases. In the case of a living room, such linear outlets are arranged along the aisle in the corridor, which is an elongated room, at the position near the wall or window near the perimeter near the outer wall (note that in the interior part of the living room). Is mainly installed so that a circular or square outlet called an anemostat etc. satisfies the indoor load, but also in this interior part, when a linear outlet is installed instead of the anemostat. There is also).

6 and 7 show an example of a ceiling and a room in which linear air outlets are arranged, and linear air outlets are used as air outlets for air-conditioned air 2 in the ceiling 1 above the room A, which is the target space for air conditioning. 3 is installed. The linear outlet 3 is arranged in the vicinity of the installation position of the window 4 (near the window) and in the vicinity of the wall 5 opposite the window 4 (near the wall) so that the longitudinal direction is along the window 4 and the wall 5.

In particular, in a room that requires a calm design such as a drawing room or an officer's room, a line above the window 4 that is the perimeter part, as in the example shown here, to give a clean impression to the ceiling. While the linear outlet 3 is installed, the linear outlet 3 may be provided above the wall 5 corresponding to the non-perimeter portion so as to be symmetrical with the linear outlet 3.

As shown in FIG. 8, the linear outlet 3 has a configuration in which a plurality of feather plates 3b are arranged along the longitudinal direction in an elongated rectangular frame 3a. An air supply chamber 6 that matches the shape of the linear outlet 3 is connected to the upper side of the linear outlet 3, and an end portion of the air supply duct 7 is connected to the air supply chamber 6.

As shown in FIG. 7, the linear outlet 3 is arranged along the ceiling 1 so that the lower surface faces the room A. The linear outlet 3 is placed on, for example, a field edge or a field edge receiver, and the face is applied from the lower surface of the ceiling 1 and is installed so as to be flush with the ceiling 1 or slightly downward from the ceiling 1. Will be done. The air supply chamber 6 is installed so that the lower surface thereof fits inside the linear air outlet 3, and is suspended and supported from above by a hanging tool or the like (not shown). The lower surface of the air supply chamber 6 is formed as an opening, and the opening communicates with the room A via the linear outlet 3.

As shown in FIG. 8, for example, the air supply chamber 6 has a trapezoidal shape with the linear outlet 3 as the base when viewed from the horizontal direction orthogonal to the longitudinal direction of the linear outlet 3, and the side surface of the trapezoidal shape. The end of the air supply duct 7 is connected to the connection port 6a provided in the air supply duct 7. Then, the conditioned air 2 sent through the air supply duct 7 is sent into the internal space of the air supply chamber 6 and is sent downward through the linear outlet 3.

As prior art documents related to the structure of this type of air supply chamber and outlet, for example, the following Patent Document 1 and the like are available.

Japanese Unexamined Patent Publication No. 10-11105

When the air-conditioned air 2 is supplied to the room A by the air supply chamber 6 and the linear outlet 3 as described above, especially when the room A is a living room, the linear outlet 3 installed on the ceiling 1 is used in the room. It is necessary to bring the conditioned air 2 to the vicinity of the floor surface of A. That is, in the corridor, people who are subject to health and air conditioning are mainly active in a standing position, whereas in the case of a living room, people are often sitting still. Therefore, in order to ensure a comfortable feeling for people in the living room, not only the air-conditioning air temperature corresponding to the indoor load but also the conditioned air 2 blown out from the linear air outlet 3 reaches the immediate vicinity on the floor as an air flow. I have to do it. In particular, in rooms such as drawing rooms and executive rooms, the demand for comfort is high, and the reach of the conditioned air 2 is even more important.

Here, during cooling, the heavy conditioned air 2 sinks downward due to its own weight, but during heating, the light conditioned air 2 tends to stay near the ceiling 1 above the room A. Therefore, especially during heating, the conditioned air 2 blown out from the linear air outlet 3 is required to have a blowout air speed of a certain level or higher.

Commercially available linear outlets 3 and air supply chambers 6 are designed according to the general space dimensions (particularly ceiling height) assumed for room A, and are usually used during heating. However, the wind speed sufficient to allow the conditioned air 2 to reach the vicinity of the floor surface can be satisfied. However, for example, when the linear outlet 3 or the air supply chamber 6 is installed in the specific room A, the height of the ceiling 1 is higher than expected at the time of designing the linear outlet 3 or the air supply chamber 6. In some cases, it may not be possible to obtain a wind speed sufficient for the conditioned air 2 to reach the vicinity of the floor surface. In the drawing room and boardroom, the ceiling height may be designed to be higher than usual, so it can be said that such problems often occur.

When the room A faces a low temperature space such as outdoors through the window 4, the indoor air cooled by the inner surface of the window 4 is cold air 8 (cold) as shown in FIG. 7. It may flow downward as a draft) and stay near the floor. Such a flow of the cold air 8 does not immediately mix with the air flow of the conditioned air 2 flowing from the linear outlet 3 of the ceiling 1 toward the floor surface due to a temperature difference, and has two layers together with the conditioned air 2. It tends to form a flow, which makes it more difficult for the conditioned air 2 to reach the floor surface. In this case, a part of the warm air stays in a layer above the room and does not contribute to the comfort of people near the floor. In the drawing room and the boardroom, a large window 4 is often installed due to the demand for a view, and in combination with the above-mentioned setting of the ceiling height, such a situation is more likely to occur.

With respect to such a linear outlet 3 and an air supply chamber 6, for example, a mechanism for adjusting the wind direction by changing the opening degree of the blade plate 3b has been often used. For example, in the line-type air outlet device described in Patent Document 1, a pair of wind direction adjusting blades are arranged on a coma shaft installed in a vertical wall forming the main body, and the wind direction is changed by rotating the coma shaft. You can do it. Then, the wind direction can be adjusted so that the air-conditioned air is blown in the vertical direction when the warm air is blown out as the air-conditioned air, and the air-conditioned air is blown out in the horizontal direction when the cold air is blown out as the air-conditioned air.

However, with respect to the linear outlet 3 and the air supply chamber 6 as described above, when the ceiling height is higher than expected at the time of designing the linear outlet 3 and the air supply chamber 6, the blowing air speed is increased to provide conditioned air. There is no known technique that can extend the reach of 2. The above-mentioned Patent Document 1 discloses a slide air volume adjusting mechanism that changes the communication opening area by a fixing blade and a slide blade at the base opening of a vertical wall, but this mechanism is referred to as a valve or a duct in terms of piping. However, the parts corresponding to the dampers are built in the main body of the outlet, and it is a mechanism that throttles the amount of air blown out from the linear air outlet so as to reduce it, and the wind speed cannot be higher than the rated air outlet speed.

In view of such circumstances, the present invention aims to provide an air supply chamber and an outlet structure capable of ensuring a reachable distance of conditioned air from a linear outlet with a simple configuration.

The present invention comprises a housing that has a longitudinal direction and forms an internal space into which conditioned air is introduced.
A connection port provided on a side wall installed along the longitudinal direction of the housing and to which an air supply duct is connected,
A lower opening provided below the housing and to which a linear outlet for sending conditioned air from the internal space is attached.
A partition plate that partitions the internal space by forming surfaces that intersect in the longitudinal direction of the housing and that can move the internal space along the longitudinal direction is provided .
A groove is provided along the longitudinal direction on the inner surface of the side wall along the longitudinal direction of the air supply chamber.
The partition plate is provided with a protrusion that engages with the groove.
It is related to the air supply chamber, which is characterized in that.

The air supply chamber of the present invention can be formed of glass wool or rock wool.

In the air supply chamber of the present invention, the outer surface of the housing may be provided with a reinforcing structure made of a metal plate.

Further, the present invention relates to an outlet structure characterized by applying the above-mentioned air supply chamber.

In the outlet structure of the present invention, an outlet angle adjusting unit that changes the angle of the blade plate provided in the linear outlet according to the temperature can be provided.

According to the air supply chamber and the air outlet structure of the present invention, it is possible to obtain an excellent effect that the reachable distance of the conditioned air from the linear air outlet can be secured by a simple configuration.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 5 show an example of the form of the air supply chamber and the air outlet structure according to the implementation of the present invention, and in the drawings, the parts with the same reference numerals as those in FIGS. 6 to 8 represent the same objects. ..

In this embodiment, the linear outlet 3 having the same shape as the outlet structure of the conventional example shown in FIG. 8 is adopted, but the shape and structure of the air supply chamber 10 is different from that of the conventional air supply chamber 6. It is different and is characterized in that a partition plate 11 is provided inside the air supply chamber 10.

The air supply chamber 10 is a box-shaped component that forms an internal space into which the conditioned air 2 is introduced. The housing 10h forming the main body of the air supply chamber 10 has a longitudinal direction and is formed with an opening below, and the dimension of the lower opening 10i is set according to the linear outlet 3. Then, the linear outlet 3 is attached to the lower opening 10i. The air supply chamber 10 includes first and second side walls 10a and 10b forming surfaces along the longitudinal direction, third and fourth side walls 10c and 10d forming both end faces in the longitudinal direction, and four side walls 10a to these. It is provided with a top surface member 10e that covers the upper part of the space surrounded by 10d. The lower opening 10i is a flanged opening in which a steel plate or the like is subjected to a dew condensation prevention treatment, and a linear outlet 3 is fitted therein.

The first side wall 10a is provided with a connection port 10f that communicates inside and outside. The connection port 10f is a flanged opening in which a steel plate or the like is treated to prevent dew condensation, and the end portion of the air supply duct 7 is connected to this opening. In this way, as shown in FIG. 1, the conditioned air 2 sent through the air supply duct 7 is sent into the internal space of the air supply chamber 10 and is sent downward from the linear outlet 3 at the lower part. In this embodiment, the connection port 10f is provided in the central portion in the longitudinal direction of the first side wall 10a, but in carrying out the present invention, the position of the connection port 10f in the air supply chamber 10 is not limited to this. , It can be changed depending on the positional relationship with the air supply duct 7 and other conditions. For example, the connection port 10f may be provided at a position near the end of the first side wall 10a.

A partition plate 11 is provided inside the air supply chamber 10 as shown in FIGS. 2 to 5, and the space in which the air conditioning air 2 is sent from the air supply duct 7 by partitioning the internal space of the air supply chamber 10. The size can be changed.

The partition plate 11 is installed so as to intersect in the longitudinal direction of the air supply chamber 10, and has a cross-sectional shape of the internal space so as to fit in the internal space surrounded by the first and second side walls 10a and 10b and the upper surface member 10e. It has a shape along with. In the case of this embodiment, the internal space of the air supply chamber 10 has a substantially rectangular parallelepiped shape, but two grooves 10g are formed along the longitudinal direction on the inner surfaces of the first and second side walls 10a and 10b. As shown in FIG. 4, the cross section orthogonal to the longitudinal direction of the internal space has a shape in which the left and right sides of the rectangle each project by the amount of the groove 10 g. The partition plate 11 has a shape in which a total of four protrusions 11a are provided on the left and right sides of a rectangular shape in accordance with the groove 10 g so as to follow this shape.

In this way, the partition plate 11 moves in the longitudinal direction along the groove 10g in the internal space of the air supply chamber 10 in a state where the left and right protrusions 11a are engaged with the grooves 10g of the first and second side walls 10a and 10b. You can do it. The groove 10g serves as a rail that engages with the protrusion 11a to regulate the movement of the partition plate 11 and at the same time also serves to hold the partition plate 11 and prevent it from falling off.

As the material of the housing 10h and the partition plate 11, various materials can be used as long as they have the strength to form an appropriate space and the nonflammability and fire resistance required as a building material. For example, it may be formed of metal, or may be formed of glass wool or rock wool. Since the air supply chamber 10 is a member forming a flow path for supplying the conditioned air 2, external dew condensation may occur when cold air is blown out as the conditioned air 2, and internal dew condensation may occur when warm air is blown out. It is preferable to use a material that can insulate the inside and outside of the chamber 10. In this embodiment, glass wool is assumed as the material of the air supply chamber 10 and the partition plate 11, and the members such as the side walls 10a to 10d and the upper surface member 10e are formed by cutting thick sheet-shaped glass wool. .. Further, the members are connected to each other by an adhesive, a fastener (not shown), or the like. Glass wool and rock wool have soundproofing properties that absorb vibrations and sounds, and at the same time, have heat insulating properties, can prevent the generation of dew condensation due to the circulation of conditioned air 2, and are also excellent in fireproofing properties. In addition, it is inexpensive, has appropriate strength and workability, and is excellent in that it can be easily formed into a required shape. Further, the outer surface of the housing 10h may be appropriately provided with a reinforcing structure (not shown) by a metal plate.

The groove 10g can be provided on the first and second side walls 10a and 10b over the entire area in the longitudinal direction, but it is not necessary to provide the groove 10g in the vicinity of the connection port 10f in the first side wall 10a. .. This is because the groove 10g plays a role of movably supporting the partition plate 11 along the longitudinal direction, but it is not necessary to arrange the partition plate 11 at the position of the connection port 10f. From the viewpoint of maintaining the reliability of the connection structure with the air supply duct 7 at the connection port 10f, it can be said that it is preferable not to provide the groove 10g in the vicinity of the connection port 10f.

Similarly, it is not necessary to provide the groove 10g in the portion of the second side wall 10b facing the connection port 10f. However, regarding the second side wall 10b, even if the groove 10g is formed in the entire area in the longitudinal direction, there is no particular inconvenience. When the air supply chamber 10 is made of glass wool or rock wool, it is easier to process by providing the groove 10g over the entire area of the second side wall 10b.

Although not shown, a pinion gear is installed in the housing 10h, for example, in order to prevent the partition plate 11 from tipping over in the housing 10h and to enable easy movement of the partition plate 11. A rack is formed in the groove 10 g and the partition plate 11 so as to mesh with each other. A hand or an instrument is inserted through the gap between the wings of the linear outlet 3, and the pinion gear is rotated to move the partition plate 11 along the groove 10 g.

Further, in the case of this embodiment, the outlet angle adjusting unit 12 is installed above the linear outlet 3. The blowout angle adjusting unit 12 is provided with a bimetal, and the bimetal is deformed according to the temperature to change the angle of the blade plate 3b. More specifically, the wing plate 3b pivotally supported by the linear air outlet 3 is provided with a bimetal so as to urge the wing plate 3b in a predetermined direction, and the wing plate is provided in the direction opposite to the bimetal. Equipped with a pull spring that urges 3b, the conditioned air 2 is sent downward with the wing plate 3b at an angle close to vertical (blow-out angle during heating) below a predetermined temperature, and the wing plate 3b is sent downward above a predetermined temperature. The conditioned air 2 is sent out diagonally downward at an oblique angle (blow-out angle during cooling).

Next, the operation of the above-described embodiment will be described. In carrying out the present invention, the target space can be assumed to have the same structure as the examples shown in FIGS. 6 and 7, and will be described below with reference to FIGS. 6 and 7 as necessary.

After constructing the ceiling 1 of the target space (indoor) A and installing the linear outlets 3 above the windows 4 and the walls 5, respectively, the outlet structure by the air supply chamber 10 of this embodiment is installed. That is, the air supply chamber 10 as shown in FIGS. 1 to 5 is connected to the upper part of the linear air outlet 3 arranged near the window or the wall of the ceiling 1, and the air supply duct 7 is connected to the connection port 10f of the air supply chamber 10. To connect.

Then, a trial run of the air conditioning equipment is performed. First, the conditioned air 2 is supplied from the air supply duct 7 to the air supply chamber 10 in a state where the partition plate 11 is brought close to the end portion in the longitudinal direction in the internal space of the air supply chamber 10. At this time, the conditioned air 2 is set to a temperature (a temperature that is not cold) so that the conditioned air 2 from the linear outlet 3 does not become the conditioned air at the time of cooling due to the operation of the conditioned air. Then, the reachable distance of the conditioned air 2 in the height direction is measured by an air flow meter or the like.

If the height of the ceiling 1 is higher than expected at the time of designing the linear outlet 3, or if strong cold air 8 is generated from the window 4, the wind speed of the conditioned air 2 at the linear outlet 3 is sufficient. Therefore, sufficient conditioned air 2 may not reach the vicinity of the floor surface. In that case, the partition plate 11 in the air supply chamber 10 is brought close to the connection port 10f (see FIGS. 2 and 3), the conditioned air 2 is supplied again from the air supply duct 7, and the reach is measured.

When the position of the partition plate 11 is brought closer to the connection port 10f, the space to which the conditioned air 2 is sent from the air supply duct 7 becomes smaller, and the space is lowered from the space through the linear outlet 3 provided in the lower opening 10i. The flow path of the conditioned air 2 blown out to is narrowed. The conditioned air 2 supplied from the air supply duct 7 is blown out at a high flow velocity, and the blowing air speed from the linear outlet 3 is increased.

The position of the partition plate 11 can be changed along the groove 10 g, and the wind speed changes according to the position of the partition plate 11. If the wind speed is too low, a sufficient amount of conditioned air 2 will not reach the vicinity of the floor surface, and if the wind speed is too high, it may become a draft and cause discomfort to residents and the like near the floor surface of the room A. Therefore, the position of the partition plate 11 is adjusted so that the wind speed near the floor surface of the conditioned air 2 which is not cold air becomes appropriate. The partition plate 11 can be moved by inserting a hand or a rod-shaped object from below the linear outlet 3. Here, when the moving mechanism of the partition plate 11 by the rack and the pinion as described above is built in the air supply chamber 10, the pinion gear is rotated from the gap between the blade plates 3b of the linear outlet 3 to partition the partition. The position of the plate 11 can be adjusted.

As described above, in the air supply chamber 10 and the outlet structure of the present embodiment, when the wind speed of the conditioned air 2 at the linear outlet 3 is insufficient, the required wind speed can be obtained only by adjusting the position of the partition plate 11. It can be easily obtained, and as shown by the broken line in FIG. 7, the conditioned air 2 can reach the vicinity of the floor surface of the target space A. The housing 10h forming the main body of the air supply chamber 10 can be easily formed by forming grooves 10g on the rectangular side surfaces 10a and 10b and combining them with the rectangular side surfaces 10c and 10d and the upper surface 10e. These members may be manufactured according to the dimensions of the linear outlet 3 at the time of construction, and while adopting a ready-made commercial product as the linear outlet 3, an air supply chamber 10 having the appropriate dimensions is used each time. Can be manufactured. Therefore, when installing the air-conditioning equipment in an actual facility, for example, it is troublesome to separately conduct a complicated study on the required wind speed according to the ceiling height and change the shape and dimensions of the linear air outlet 3 accordingly. It is not necessary and it is possible to set an appropriate wind speed for each site at low cost and easily. In particular, if the air supply chamber 10 and the partition plate 11 are manufactured of glass wool or rock wool, the material cost is low, the processing is easy, and the manufacturing cost can be minimized.

Although the case where two partition plates 11 are installed so as to sandwich the connection port 10f to which the air supply duct 7 is connected to the air supply chamber 10 is described here, the number of partition plates 11 is limited to this. Not done. Even if there is only one partition plate 11, if it is arranged between the connection port 10f and the third or fourth side wall 10c, 10d at the end, it communicates with the air supply duct 7 to provide the conditioned air 2. The size of the space to be introduced can be changed by the partition plate 11, and the wind speed of the conditioned air 2 blown out from the linear outlet 3 can be adjusted.

In this way, the wind speed of the conditioned air 2 during heating can be secured by changing the position of the partition plate 11. On the other hand, when the position of the partition plate 11 is determined based on the reach of the conditioned air 2 during heating, the wind speed becomes excessive during cooling, and a strong air flow hits the occupants near the floor surface. It can cause discomfort.

Here, although it is not impossible to manually change the position of the partition plate 11 between cooling and heating, although the partition plate 11 can be easily moved, a resident who is not an equipment supplier or the like In reality, it is difficult to imagine the use of the partition plate 11 by inserting a hand or an object from the linear outlet 3. Therefore, in this embodiment, the linear outlet 3 is provided with the outlet angle adjusting unit 12, so that the angle of the blade plate 3b is automatically changed according to the temperature.

That is, during heating, the wing plate 3b is set at an angle close to perpendicular to the floor surface (blow-out angle during heating), and the conditioned air 2 is sent downward so that the conditioned air 2 reaches the vicinity of the floor surface (broken line in FIG. 7). (Refer to), the angle of the wing plate 3b is slanted while maintaining the same wind speed of the conditioned air 2 during cooling, and the conditioned air 2 is slanted with respect to the floor surface (blow-out during cooling closer to the ceiling 1 than the blow-out angle during heating). By sending out (at the corner) (see the one-point chain line in Fig. 7), it is possible to prevent a strong air flow from reaching the floor surface as a cold draft as it is, and as a result, warm air staying in a layer above the room. I am doing it. By doing so, it is possible to realize comfort in the room A both during heating and during cooling.

Here, an example is shown in which the angle of the wing plate 3b is automatically changed by the blowout angle adjusting unit 12 provided with bimetal without any external operation, but the wing is changed according to heating or cooling. The mechanism for adjusting the angle of the plate 3b is not limited to this, and for example, a mechanism for adjusting the angle of the blade plate 3b by the operation of a motor or the like may be separately provided. However, if the bimetal type blowout angle adjusting unit 12 that automatically changes the angle of the blade plate 3b according to the temperature is adopted as in this embodiment, the blowout angle of the conditioned air 2 can be adjusted particularly inexpensively and easily. It is possible.

As described above, the air supply chamber 10 of the present embodiment and the outlet structure to which the air supply chamber 10 is applied have a longitudinal direction, and a housing 10h forming an internal space into which the air conditioning air 2 is introduced and a housing 10h. A linear outlet 3 provided on the side wall 10a installed along the longitudinal direction of the above and to which the air supply duct 7 is connected and below the housing 10h to send out the conditioned air 2 from the internal space. The lower opening 10i is provided with a partition plate 11 for partitioning the internal space by forming a surface intersecting the longitudinal direction of the housing 10h and allowing the internal space to be moved along the longitudinal direction. By doing so, the required wind speed can be easily obtained at the linear air outlet 3 only by adjusting the position of the partition plate 11.

In the air supply chamber 10 of this embodiment, a groove 10 g is provided along the longitudinal direction on the inner surfaces of the side walls 10a and 10b along the longitudinal direction of the air supply chamber 10, and the partition plate 11 is engaged with the groove 10 g. Since the matching protruding portion 11a is provided, the movement of the partition plate 11 can be defined in the direction along the groove 10g, and the partition plate 11 can be held by the groove 10g to prevent it from falling off.

The air supply chamber 10 of this embodiment can be formed of glass wool or rock wool, so that the air supply chamber 10 can be easily manufactured at low cost according to the dimensions of the linear outlet 3. can. Further, in the air supply chamber 10, it is possible to prevent the occurrence of dew condensation due to the flow of the conditioned air 2.

The air supply chamber 10 of this embodiment may be provided with a reinforcing structure by a metal plate on the outer surface of the housing 10h.

In the outlet structure of the present embodiment, an outlet angle adjusting unit 12 that changes the angle of the blade plate 3b provided in the linear outlet 3 according to the temperature can be provided, and in this way, the air-conditioned air 2 can be provided. By changing the angle of the wing plate 3b between heating and cooling while maintaining the wind speed of the above, comfort in the room A can be realized in both heating and cooling.

Therefore, according to the present embodiment, the reach of the conditioned air from the linear outlet can be secured by a simple configuration.

The air supply chamber and outlet structure of the present invention are not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
