Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiation air conditioner for cooling or heating by absorbing or radiating infrared rays.

[0002]

2. Description of the Related Art Conventionally, a radiation air conditioner of this type is described in, for example, Japanese Utility Model Publication No. 2-28339. That is,
As shown in FIG. 5, 1 is a radiant air conditioner, 2 is a heat medium pipe serving as a heat source for cooling or heating, 3 is a front plate having a radiating surface 4, 5 is a back plate, and 6 is a hollow of the radiant air conditioner 1. It is a heat insulating material filled in the part.

When a heat medium such as cold water or hot water is supplied to the heat medium pipe 2, heat is exchanged between the heat medium pipe 2 and the surface plate 3, and the radiation surface 4 of the surface plate 3 absorbs or emits infrared rays. Radiation cooling or heating in the room is performed.

[0004]

Radiant air conditioning is comfortable for the user because no airflow is generated during air conditioning. However, during cooling, the radiation surface is at a low temperature, so in the above-mentioned configuration, when the humidity is high during cooling, the surface temperature of the outer pipe decreases, condensation occurs on the surface, and corrosion and mold due to the drop of water drops occur. There was a problem.

The present invention has been made in view of the above-described facts, and an object thereof is to prevent dew condensation on the outer pipe and prevent corrosion and mold while performing good radiation air conditioning. .

[0006]

According to the present invention, there is provided a heat source for cooling or heating having a radiation surface, and an infrared-transparent heat insulator covering the radiation surface of the heat source.

[0007]

[Function] Since the heat radiating surface of the heat source is provided with the infrared permeable heat insulator, the radiant surface of the heat source can be insulated and the dew condensation on the radiant surface can be prevented without hindering the infrared ray from being radiated and absorbed. It is possible to prevent corrosion and mold.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 2 is a heat medium pipe serving as a heat source for cooling or heating, 4 is a radiation surface of the heat medium pipe 2, and 7 is a radiation surface.
Is a heat insulator covering the radiation surface 3. Further, as the heat insulating body 7, an infrared transparent heat insulating material such as a silica-based foam material which is transparent to infrared rays is used. As a result, the radiation surface 4 of the heat medium pipe 2 that is cooled during cooling can be isolated from the humid air, and infrared rays to the radiation surface 4 can be transmitted, so that dew condensation can be prevented and the heat insulator 7 Since it has infrared transparency, radiation air conditioning can be performed without any trouble.

Another embodiment of the present invention will be described with reference to the drawings. In FIG. 2, 2 is a heat medium pipe serving as a heat source for cooling or heating, 4 is a radiation surface of the heat medium pipe 2, and 8 is a radiation surface. Is an outer tube that is mounted outside the heat medium pipe 1 with a space S therebetween and covers the radiation surface 4 in an airtight manner, and the space S is maintained in a vacuum. The outer tube 8 is made of an infrared-transparent material such as Tuftran (a trade name of Montthiocol Co., USA), which is a composite material of zinc sulfide and zinc selenide, which is transparent to infrared rays, and halogen glass. There is. That is, in this embodiment, the space S and the outer tube 8 constitute the infrared-transmissive heat insulator 7.

As a result, the surface temperature of the radiation surface 4 decreases during cooling in which cold water is supplied to the heat medium pipe 2, but since the surrounding area is a vacuum layer, no condensation occurs on the radiation surface 4. Further, since the infrared ray transmissive material is used for the outer tube 8, the radiation air conditioning can be performed without any trouble.

Although the surface of the heat medium pipe 2 is described as the radiation surface 4 in the above-mentioned embodiment, as shown in FIG. 5, in the case where the heat medium pipe 2 is provided with the surface plate 3, the surface plate 3 is provided. The radiation surface 4 may be covered with an infrared permeable heat insulator, and the present invention is applicable to various radiation air conditioners.

[0012]

As described above, according to the present invention, since the infrared ray-transmitting heat insulating body for covering the radiation surface of the surface plate is provided, the radiation surface of the heat source is insulated to the radiation surface without hindering the radiation and absorption of infrared rays on the radiation surface. Since the dew condensation can be prevented and the heat insulator has infrared ray transparency, comfortable radiant air conditioning can be performed.
