Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is used for a cooling system by blowing cold air from a ceiling plate and cooling radiation, especially for a house, which has a place where steam is generated, such as a kitchen and a bathroom. Air conditioner ceiling plate.

(Prior Art) Conventionally, for example, an in-ceiling space is formed through a ceiling plate having an air blowing hole, and cool air is blown into the in-ceiling space to blow cold air from the air blowing hole and cool the ceiling plate from the ceiling plate. In a cooling system that radiates radiation, an aluminum plate, an iron plate, or the like having good heat conductivity and a small heat capacity is used for the ceiling plate.

(Problems to be solved by the invention) However, in the cooling system equipped with such a ceiling plate, a large amount of water vapor generated in the kitchen, bathroom, etc. during the summer cooling is condensed on the lower surface of the cooled ceiling plate, which is extremely large. Sometimes it had the drawback of dropping water drops.

The purpose of this plan is to eliminate the conventional drawbacks.

(Means for Solving the Problem) As a means for solving the above problems, an air conditioning ceiling board of the present invention has a ceiling space formed through a ceiling board having an air blowout hole, and an air conditioner having a dehumidifying function. The air intake of the machine is opened in the room, the air outlet is opened in the space above the ceiling, and it is a ceiling plate in the cooling system that blows cold air from the ceiling plate and radiates cold air. The configuration is characterized by the provision of

The humidity-conditioning material in this plan has hygroscopicity, water-absorbing property, and moisture-releasing property, and absorbs dew-condensed water when it comes into contact with it, but dissipates absorbed water as the indoor humidity decreases. It is a paint, sheet or spraying material that mainly contains polymers. For example, Kikusui Chemical Co., Ltd.'s anti-condensation paint "Keturo Nine", anti-condensation wall material "Keturo Nine sheet", and spraying material "Glite" manufactured by Glight Industry Co., Ltd. are available.

An embodiment of the present invention will be described below with reference to the drawings.

(Embodiment) In FIG. 1, a ceiling board (2) having a large number of air blowing holes (3) ... ) Is formed on the upper side wall of the room, and a cooler (5) having a dehumidifying function is attached to the room, the air intake (6) of the cooler (5) is installed in the room, and the air outlet (7) is installed in the ceiling above the ceiling. Each of the openings is opened in the space (4), whereby the air taken in from the room by the air conditioner (5) is cooled to send dehumidified cooling air into the space above the ceiling (4), and the ceiling plate (2) is cooled. The ceiling plate (2) is used as a radiation panel to radiate cold air into the room, and at the same time, cool air is emitted into the room through the air outlet holes (3) of the ceiling plate. There is.

The ceiling plate (2) has a humidity control material layer (9) formed on the inner surface of the ceiling substrate (8) made of an aluminum plate having air blowout holes (3) ... .
The humidity control material layer (9) is formed by applying a coating material containing the humidity control material as a main component, attaching a sheet containing the humidity control material as a main component, spraying a spray material containing the humidity control material as a main component, and the like. As an example, the thickness of the humidity control material layer is about 1 mm or less.

When cool air is sent from the air conditioner (5) into the space above the ceiling (4) partitioned by the ceiling plate (2) in the summer, the ceiling substrate (8) made of an aluminum plate is immediately cooled, and then the adjustment is performed. The wet material layer (9) is also cooled, whereby cold radiation is performed from the inner surface of the interior of the humidity control material layer (9), and cold air is blown into the room from the blowout holes (3).

When water vapor generated in the kitchen, bathroom, etc. enters the room, it will come into contact with the humidity control material layer (9) surface of the cooled ceiling plate (2) to cause dew condensation, and these dew condensation water will be absorbed by the humidity control material layer (9). It will not drop as water drops. Since water vapor in the kitchen, bathroom, etc., enters the room only temporarily, if the cooling continues, the room humidity will decrease due to its dehumidifying action, and as a result, it will be absorbed by the humidity control material layer (9). The water is dissipated,
Eventually it is released outdoors. Then, the humidity control material layer (9) returns to the original state.

In another embodiment of FIG. 1, a strip-shaped ceiling component plate (10a) having a humidity control material layer (9a) formed on the outer surface of an aluminum substrate (8a) having a flat cross section is formed into a rod shape. The ceiling support frames (11a) assembled in a grid pattern are fixed to each other at small intervals with a set screw (12a).
0a) (10a), ... Slit-like air blowout holes (3a) ...
It is a ceiling plate (2a) that has formed.

(Effect of the device) According to the ceiling plate for air conditioning of the present invention, even if a large amount of water vapor enters the room temporarily and dew on the ceiling plate, the humidity control material absorbs the condensed water and prevents it from dripping into the room. In addition, the humidity control material that has absorbed the water can dissipate the water by the dehumidifying action of the air conditioner so that the humidity control material can absorb the next condensed water.
