Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an air conditioner having a panel for ceiling radiation air conditioning.

[Conventional technology]

FIG. 2 is a schematic diagram of a conventional ceiling radiation type air conditioner.

In FIG. 2, a cooled medium or a heated heat medium is sent from the outdoor unit 2 to the panel 21 made of a porous ceiling material through the pipe 3. The indoor space 4 has a panel 21 made of a porous ceiling material that has been cooled or warmed.
To cool or heat. Further, on the ceiling side of the ceiling panel 21, an air blower 5 for disposing condensed water during cooling operation is arranged.

FIG. 3 shows a sectional view of a panel 21 made of a conventional porous ceiling material. Ceiling panel 2 made of porous material
1 includes a pipe 22 which is cooled or warmed and through which a heat medium passes, and a cloth 23 is arranged on the indoor space side thereof, and the cloth 23 is fixed to a side surface 24 of a panel 21. In addition, the lower surface 28 of the ceiling panel 21 made of a porous material
Is flat. When the cooling operation is performed using such a ceiling panel 21, a cold heat medium passes through the pipe 22, the panel 21 made of a porous material is cooled, and the cloth 23 attached to the indoor side of the panel 21 is cooled. The surface is also cooled, and the water in the room is condensed and adheres as dew 26. Dew 26
Is sucked up from the lower surface 28 of the panel 21 made of porous material as shown by an arrow 29 and reaches the upper surface 27 of the panel 21.
The dew 26 is condensed with the condensed water 29 by the air 25 sent by the blower device 5 and evaporated to be discharged to the outside.

[Problems to be solved by the device]

The ceiling panel 21 made of the above-mentioned conventional porous material has the following problems.

(1) When the cooling operation is performed for a long time by the ceiling panel 21, a gap 30 is formed between the panel 21 and the cloth 23 due to the hanging of the cloth 23. Therefore, the dew 26 on the cloth 23 cannot be sucked up by the porous material of the panel 21, and the condensed water 29 drips from the cloth 23 into the room.

(2) Due to the gap 30, heat is not transferred between the ceiling panel 21 and the cloth 23, and the cooling capacity of the ceiling panel 21 decreases.

The present invention is intended to solve the above drawbacks of the air conditioner having the conventional ceiling panel.

[Means for Solving the Problems]

The ceiling radiant air conditioner of the present invention uses a porous material containing a heat medium pipe for cooling and heating the ceiling panel to make its interior side convex, and a sheet is attached to the interior side surface of the ceiling panel, The convex surface of the panel was made to project from the panel side where the cloth was fixed to the inside of the room.

[Action]

In the present invention, the inner surface of the porous material that constitutes the ceiling panel is convex as described above, and the cloth is attached to this, so that there is a gap between the sheet and the surface of the porous material during use. The dew condensed on the cloth is sucked up to the ceiling side of the ceiling panel by the porous material and does not fall into the room.

Further, since no gap is formed between the sheet and the surface of the porous material of the ceiling panel during use, the cooling and heating capacity of the ceiling panel does not deteriorate.

〔Example〕

An embodiment of the present invention will be described with reference to FIG. In this embodiment, the ceiling panel 21a is arranged on the ceiling portion of the indoor space 4 as shown in FIG. 2 similarly to the above-mentioned conventional apparatus, and the surface 27 on the ceiling side is provided with the air blower 5 for sending the air 25. ing.

The ceiling panel 21a, like the above-mentioned conventional ceiling panel,
A heat medium pipe for cooling and heating, which is made of a porous material, is built in, a cloth 23 is arranged on the surface on the indoor side, and the cloth 23 is fixed by a fixing portion 24 on the side surface of the panel 21a.

A surface 28a on the indoor side below the ceiling panel 21a is convex downward and forms a curved surface having a central portion protruding from the fixed portion 24.

In this embodiment, when the cooling operation is performed, the pipe 22
The cooled heat medium passes through, the ceiling panel 21a is cooled, the surface of the cloth 23 attached to the indoor side of the panel 21a is also cooled, and the moisture in the room is condensed to form the dew 26 and the cloth 23.
Adhere to. This dew 26 is formed on the lower surface 2 of the ceiling panel 21a.
8a is sucked up through the pores of the porous material as indicated by an arrow 29, and the upper surface 27 is provided on the ceiling space side of the ceiling panel 21a.
And is vaporized by the air 25 sent by the air blower 5 and discharged to the outside.

In this embodiment, even if the ceiling panel 21a is used for a long time,
Since the interior-side lower surface 28a of the ceiling panel 21a is formed so as to project downward, the dew 26 attached to the surface of the cloth 23 does not cause the cloth 23 to hang down as in the conventional example.

As described above, in the present embodiment, the cloth 23 does not hang from the lower surface 28a on the indoor side of the ceiling panel and a gap is not formed between the two, so that the dew condensed on the cloth 23 becomes the ceiling porous material. Therefore, it is not sucked up by the ceiling-side surface 27 of the ceiling panel 21a and evaporated, and does not fall into the indoor space 4. Further, as described above, since no gap is generated between the ceiling panel surface 28a and the cloth 23 during use, the cooling and heating capacities do not deteriorate.

In the present embodiment, the lower surface 28a of the ceiling panel 21a is
Although the cloth 23 is pasted on the cloth, the same effect can be obtained with cloth, paper or the like.

[Effect of device]

As described above, the present invention can achieve the following effects because the seat and the surface of the convex ceiling panel on the indoor space side are not separated from each other during operation, and a gap is not formed therebetween.

(1) Condensation formed on the seat surface during cooling operation is sucked up and evaporated through the porous material of the ceiling panel and does not fall into the indoor space.

(2) The heat conduction from the ceiling panel to the seat is improved, and the cooling and heating effect can be enhanced.
