Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large number of beam members extending in parallel along a ceiling surface for air conditioning in a high quality space such as an office, a computer terminal room, a conference room, etc. The present invention relates to an air conditioning method for a system ceiling configured by mounting a board, a lighting fixture, or the like, or a double space ceiling partitioned by ceiling panels.

[0002]

2. Description of the Related Art Conventionally, for example, as an air conditioning method for the above-mentioned system ceiling, as shown in FIGS. 6 to 7, a suspension bolt and a T bar are assembled from an upper slab 25, and a ceiling panel 26 is arranged. A heavy space ceiling is formed, this ceiling space 27 is used as an air supply chamber, and conditioned air 30a such as cold air or warm air is supplied from the air supply port 28a to the ceiling space 27 by a blower 28, and the ceiling space is provided at a desired position. Outlet 29
The conditioned air 30a is supplied to the room 30 from. The conditioned air 30a filled in the room is blown by the blower 28 again.
The air is circulated by being exhausted to.

[0003]

However, in the above-mentioned air conditioning method, since the space 27 above the ceiling is used as the air supply chamber, there is a large heat loss to the upper slab 25 having a large heat capacity, and the radiation effect of the ceiling panel 26 is also increased. I can't expect much. Further, there is a drawback that the radiation effect to the room on the ceiling surface is not sufficiently obtained. That is, since the conditioned air blown out from the air outlets provided at a plurality of positions on the ceiling surface only blows vertically downward, this is good for warm air at the time of heating, but it is better for cold air at the time of cooling. In some cases, cold air will be blown out locally, which is not suitable for uniformly cooling the entire room, and the radiation effect on the ceiling surface can only be expected due to the fact that it is cooled only by the cold air inside the ceiling. It was not there.

The present invention has been made in view of the above problems, and cools and heats both surfaces of the ceiling surface by the conditioned air in the ceiling space and the conditioned air blown along the lower surface of the ceiling panel inside the room. It is an object of the present invention to provide an air conditioning method for a double space ceiling, which is configured to enhance the radiation effect on the ceiling surface.

[0005]

The gist of the present invention to solve the above problems and achieve the above objects is to provide a double space ceiling having an open closed space through which conditioned air on the ceiling passes. Conditioned air blown out from the air outlet into the room, with the outflow direction of the air outlet directed substantially parallel to the ceiling surface,
It lies in that the air was blown in parallel along the ceiling panel surface on the indoor side.

[0006]

According to the double space ceiling of the present invention, the conditioned air blown indoors from the air outlet is formed by the direction plate, and its outflow direction is made substantially parallel to the ceiling surface from the air outlet. Since it flows out in parallel with and flows along the ceiling panel surface due to the Counder effect, the ceiling panel is cooled and heated. Therefore, the ceiling panel is cooled / heated on both sides thereof by the conditioned air in the ceiling space and the conditioned air that has become a sympathetic air flowing along the ceiling panel surface on the indoor side.・ The amount of heating increases and the radiant heat increases.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an air conditioning method according to the present invention, and FIG. 2 is an enlarged partial cross-sectional view of an air outlet attached to a ceiling panel. 3 is a sectional view showing an air conditioning method according to another embodiment, and FIG. 4 is a partially enlarged sectional view thereof,
FIG. 5 is a plan view of the same. In the figure, reference numeral 1 is an upper slab, 2 is a ceiling panel, 3 is a ceiling space, 4 is an outlet, and 4
a is a direction board, 5 is a lighting device, 6 is an indoor space, 7 is a floor surface,
Reference numeral 8 is an air conditioner, 9 is an air supply duct, and 10 is an exhaust duct.

[0008] The method of adjoining flow radiation air conditioning in a double space ceiling of the present invention is to cool and heat both surfaces of the ceiling panel 2 with conditioned air. A hanging bolt or T on the lower side of the upper slab 1.
The ceiling surface is formed by the ceiling panel 2 suspended by a bar or the like (not shown) to form a double space ceiling. Then, on the ceiling panel 2, conditioned air outlets 4, 4, ... And a lighting device 5,
5, ... Are provided at appropriate intervals in the left-right direction and the direction perpendicular to the paper surface.

One end side of the air supply duct 9 of the air conditioner 8 is open to the ceiling space 3 so as to communicate therewith, and one end side of the exhaust duct 10 is opened from the indoor space 6 to be arranged. The other end side is communicated with and connected to the air conditioner 8.

At the air outlet 4, as shown in FIG. 2A, the conditioned air from the air conditioner 8 supplied to the ceiling space 3 passes through the inside of the air outlet main body 4b to form a T-shape. It collides with the direction plate 4a and flows in the left-right direction in the drawing as indicated by an arrow. The direction plate 4a is not limited to the shape shown in the figure, but it is also preferable that the direction plate 4a has a shape with a smooth curve so that the conditioned air can smoothly flow along the ceiling panel 2.

In this way, the double space ceiling is formed, and the ceiling panel 2 is further provided with the air outlet 4 having the direction plate 4a, and the conditioned air is supplied to the ceiling space 3 through the air supply duct 9 by the air conditioner 8. If supplied, the top surface of the ceiling panel 2 is cooled and heated by the conditioned air supplied to the ceiling space 3, and
On the lower surface of the ceiling panel 2 on the indoor space 6 side, the direction plate 4a causes the air to flow out in parallel with the ceiling panel 2 and is cooled and heated by conditioned air flowing along the ceiling panel 2 by the Counder effect.

Therefore, the upper and lower surfaces of the ceiling panel 2 are cooled and heated by the conditioned air, and the conditioned air is cooled and heated more efficiently than when the conditioned air is simply blown to the indoor space 6 in the vertical direction. The radiation effect by becomes large.

As another embodiment of such an air conditioning method,
The one shown in FIG. 3 can be proposed. In the air conditioning method described above, the ceiling space 3 is used as a conditioned air supply chamber,
In the other embodiment, the blowing device 11 and the lighting device 5 are suspended from the upper slab 1 by hanging bolts or the like to form a double space ceiling, and a fan 12 provided in the ceiling space 3 is used to form the indoor space 6
Air of the above is exhausted to the ceiling space 3 through the exhaust passage 13,
The ceiling space 3 is used as a return chamber.

The air supply duct 9 of the air conditioner 8 is directly connected to the blow-out device 11, and conditioned air is supplied from the air supply duct 9 to the blow-out device 11. 6 is supplied. Further, one end side of the exhaust duct 10 is opened to the ceiling space 3 and the other end side thereof is connected to the air conditioner 8.

As shown in FIG. 4, the structure of the blowing device 11 is a metal frame 1 having a rectangular cross section and long in the direction perpendicular to the plane of the drawing.
4, a heat insulating material 15 such as glass wool laid on the upper side of the frame 14 in a flat plate shape, and a metal or rock wool laid on the lower side of the frame 14 at a distance from the heat insulating material 15. The flat panel-shaped ceiling panel 16 and the left and right central portions of the frame 14 are pierced through the heat insulating material 15 from above and the lower portion is piped, while the branch pipe 9a of the air supply duct 9 is connected to the upper portion. Air supply pipe 17 and a direction plate 18 at the bottom of the frame 14.
And an outlet 19 formed by Note that FIG.
[Fig. 3] is a plan view showing an arrangement state of a blowing device 11 and a lighting device 5 as viewed from the inside of a room. The arrow in the figure indicates the flow of conditioned air blown out from the air outlet 19.

In the air-conditioning method based on the above-described formation, as shown in FIGS.
From each air supply pipe 17 through the air supply duct 9 and the branch pipe 9a.
And then split in the left and right direction at the mouth 20, and the blowing device 1
From the outlets 19 at the left and right ends of the frame 14 of the first ceiling panel 1
6 flows out into the indoor space 6.

Therefore, the conditioned air cools and heats both surfaces of the ceiling panel 16 as described above. On the other hand, the conditioned air that has flowed out into the indoor space 6 is convected as shown by the arrow in FIG. 3, and is exhausted from the exhaust passage 13 to the ceiling space 3 by the fan 12, and this ceiling space 3 becomes a return chamber and the exhaust duct 10 Return to the air conditioner 8 via. The conditioned air is also exhausted from the flow path from the indoor space 6 through the gap of the lighting device 5 to the ceiling space 3.

Although the air conditioning method according to the present invention is as described above, the structure of the conditioned air outlet is not limited to that shown in FIG. 2A, but the one shown in FIG. 2B is also preferable. is there. That is, the direction plate 21 can automatically move in and out of the air outlet depending on whether the conditioned air is cold air or warm air. The direction plate 2 is used for the direction plate 2
This is done by connecting and supporting a support 22 made of a shape memory alloy on top of 1.

Therefore, when the conditioned air is warm air, the direction plate 21 rises upward, and the warm air is blown out to the indoor space 6 in the vertical direction, which promotes the convection of warm air (shown by a solid arrow). become. When the conditioned air is cool air, the direction plate 21 is lowered downward, and cool air (shown by a dashed arrow) is blown out along the ceiling panel 2. This is done so that when the conditioned air is warm air, it does not collect near the ceiling, and it promotes convection of warm air rather than expecting the radiation effect of the ceiling panel 2, and when cold air is used. This is because both the radiation effect and the convection effect of the ceiling panel 2 can be expected.

As described above, it is needless to say that the shape, size and the like of the outlet can be variously changed within the scope of the present invention. Further, the air conditioning method of the present invention can be applied not only to the structure of the double space ceiling but also to the chamber box system by arranging a large number of chamber boxes in parallel and putting them on the ceiling surface.

[0021]

As described above, according to the method of co-existing radiant air conditioning in a double space ceiling of the present invention, the conditioned air blown out from the air outlet to the room from the double space ceiling ceiling space is blown. The direction plate provided at the outlet directs the outflow direction of the outlet to be substantially parallel to the ceiling surface, and blows it parallel to the ceiling panel surface on the indoor side. The radiant heat from the heated ceiling panel is much higher than before and the radiant efficiency is improved. As a result, the indoor space is not locally heated or cooled,
The entire room is air-conditioned to provide a comfortable living and work space.
