Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to air conditioning equipment for building structures, and particularly to a ceiling chamber type air supply device.

<<Background of the Invention>> As is well known, one of the air conditioning methods for building structures is to use the attic of the structure as an air supply chamber. It has various advantages, such as less duct work, shorter construction period, lower construction costs, and lower ventilation resistance, which reduces blower power.

However, this type of method also has the following problems.

In other words, if there is an obstruction in the air supply chamber in the attic that impairs the flow of conditioned air, circulation flow will likely occur locally within the chamber, but if there is an obstruction in the attic, such as a beam on the upper floor slab, However, there was a problem in that it was actually difficult to remove it, and it was easy to be affected by the negative effects of obstacles.

To prevent this, for example, you can increase the ventilation resistance at the outlet or install an air volume adjustment damper on each outlet, but if the ventilation resistance is increased, the power of the blower becomes excessive, and this type of method Moreover, if a damper is installed, it becomes a specially constructed air outlet, which loses its economic advantage.

On the other hand, in this type of system, conditioned air is blown downward from the air supply chamber, and the exhaust vents are generally installed near the indoor floor, and in order to connect the exhaust vents on each floor, Another problem was that the exhaust duct had to be routed inside the structure.

The present invention has been made in view of the above-mentioned background, and an object of the present invention is to maintain the advantages of the ceiling chamber air supply type, even with a relatively simple configuration, and to connect the supply/exhaust duct and chamber. An object of the present invention is to provide a ceiling chamber type air supply device that can be easily connected.

≪Means for Solving the Problems≫ In order to achieve the above object, the present invention opens the end of the air supply duct to the attic space, uses this space as an air supply chamber, and connects the air outlet provided in the ceiling with the air supply duct. In a ceiling chamber-type air supply device that blows conditioned air into a room, a pair of air supply chambers are formed on both sides of an exhaust chamber along the central axis of the attic space, and each of these supply and exhaust chambers has a The air supply/exhaust duct is connected to the air supply/exhaust duct provided integrally along the outer surface of the outer wall of the building structure, and the air supply duct is opened to each air supply chamber from the opposite side of the exhaust chamber. .

<<Operation>> In the supply air chamber, conditioned air flows from the opposite direction toward the central exhaust chamber side, so if a beam is provided in the same direction as the conditioned air, this influence can be prevented.

The supply and exhaust duct that connects the supply and exhaust chambers is
It is connected to the outer surface of the outer wall of the structure without straying inside, allowing effective use of internal space.

<<Example>> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show an embodiment of a ceiling chamber type air supply device according to the present invention.

The air supply system shown in the same figure is applied to a building structure with a rectangular horizontal cross section as shown in the overall plane in Fig. 1.
On the 4th floor), the attic space 10 is used as supply/exhaust chambers 12 and 14.

On the lower surface of each flat slab 16 that vertically defines each floor, a pair of partition walls 18, 18 are arranged parallel to each other at a predetermined interval along the central axis _O1 along the longitudinal direction of the attic space 10. The space between these becomes the exhaust chamber 14, and the pair of air supply chambers 1 are sandwiched between them on both sides.
2 and 12 are formed.

In the example shown in FIG. 1, the partition walls 18 are arranged along the pillars 19, but the invention is not limited thereto.

A ceiling material 22 supported by hanging fittings 20 is disposed below the supply/exhaust chambers 12, 14,
Chambers 12 and 14 are installed at appropriate locations on the ceiling material 22.
A conditioned air outlet 24 and a discharge outlet 26 are installed to communicate the air conditioner and the room.

Air supply ducts 30 are integrally formed along the outer surface of the outer wall 28 of the structure, and a pair of air supply ducts 30 are provided horizontally along the outer surface in the longitudinal direction on each floor. , are opened from the opposite side of the exhaust chamber 14 to the respective air supply chambers 12, 12 via an air supply port 31.

Details of the air supply duct 30 are shown in FIG.

The air supply duct 30 shown in the same figure is located slightly above the flat slab 16 of each floor, and integrally forms a convex portion 28a that protrudes outward from the outer wall 28 below the window frame 32 of the upper floor. A panel 34 having an L-shaped cross section is fixed between the portion 28a and the upper outer wall 28 of the window frame 32 on the lower floor, so that the outer wall 28 and the convex portion 28
The lower surface of a and the panel 34 define an air supply duct space 36 having a substantially rectangular cross section.

The air supply duct space 36 and the air supply chamber 12 communicate with each other via the air supply port 31 passing through the outer wall 28 .

The panel 34 is equipped with a heat insulating material 38 made of foamed urethane or the like, and includes the convex portion 28a in the air supply duct space 36, the outer surface of the outer wall 28, the air supply port 31, and the flat slab 1 in the air supply chamber 12.
A heat insulating material 38 made of a similar material is attached to the lower surface of the outer wall 6 and the inner surface of the outer wall 28.

In the air supply device having the above configuration, each air supply duct 30 is connected to the air supply chamber 1 through the air supply port 31.
The conditioned air sent to 2 and 12 is sent to each outlet 2.
4 and into the exhaust chamber 14 through the central exhaust port 26.

Here, the air flow from the air outlet 31 to the exhaust chamber 14 is directed to the air outlet 24 closest to the air outlet 31.
The air volume reaches its maximum at In this case, the amount of air is almost uniform, and good air conditioning is achieved.

Furthermore, if the beams reinforcing the flat slab 16 are provided in the same direction as the flow of conditioned air within the air supply chamber 14, that is, in the short direction of the attic space 10 in this embodiment, the beams reinforcing the flat slab 16 will not obstruct the flow of conditioned air. There's nothing to do.

Further, for example, if individual air conditioning equipment is provided on each floor, the air supply duct 30 and exhaust chamber 14 on each floor may be connected to the air conditioning equipment, respectively.
In addition, in a centralized system where air conditioning equipment is installed in the basement or rooftop, air supply ducts 3 and 3 on each floor are installed as shown in Figure 1.
The air supply intermediate duct 40 that vertically connects the air supply chambers 14 and the exhaust intermediate duct 42 that similarly connects the exhaust chambers 14 of each floor can be integrally provided along the outer wall 28 and connected to the air conditioning equipment. There is no need to run the exhaust duct inside the structure, and the internal space can be used effectively.

Note that the air supply port 31 opened to the air supply chamber 12 on the same floor may be provided with a damper for adjusting the amount of air.

In addition, the exhaust chamber 14 shown in the above embodiment
may also be provided along the central axis of the attic space 10 in the lateral direction.

<<Effects of the Invention>> As described above in detail in the examples, the ceiling chamber type air supply device of the present invention enables good indoor air conditioning while maintaining the characteristics of this system, and also improves air supply.・Since the exhaust duct and chamber can be connected without straying inside the structure,
Excellent effects such as the effective use of internal space can be obtained.
