This panel 10 is a PC
It is composed of a (precast concrete) panel, and a cold / hot water pipe (pipe) 11 for circulating cold water or hot water is embedded in the center of the inside thereof.

FIG. 2 shows a concrete pipe example of the cold / hot water pipe 11. The cold / hot water forward path L1 and the return path L2 form one system of pipeline for circulating the cold / hot water.
The cold / hot water pipe 11 has an inner diameter of 7 mm and an outer diameter of 10 mm, for example.
It is composed of cross-linked polyethylene pipe. Also,
FIG. 3 shows a specific configuration example of the panel 10. A wire mesh 12 is arranged on the outside of the hot and cold water pipe 11 (a position near the surface 10A of the panel 10 in the figure). The wire mesh 12 has a function of reinforcing the panel 10 and, in particular, transmitting heat evenly between the cold / hot water pipe 11 and the entire surface of the panel 10.

In the panel 10 having the above structure,
By passing cold water or hot water through the cold / hot water pipe 11, the front surface 10A and the back surface 10B of the panel 10 radiate or absorb heat, and the rooms R1 and R2 can be simultaneously radiantly cooled or radiantly heated. By the way, according to an experiment by the present inventors, the heat transfer function of the wire mesh 12 causes the surface 10A on which the wire mesh 12 is located during radiation cooling.
The temperature on the side was 0.5 ° C. lower than that on the back surface 10B side.

Therefore, the amount of heat radiation and the amount of heat absorption on the front surface 10A and the back surface 10B of the panel 10 can be made different depending on the bar arrangement position of the wire mesh 12.
Further, by arranging the wire meshes 12 on both sides of the cold / hot water pipe 11 in the front-back direction of the panel 10, the heat radiation amount and the heat absorption amount on the front surface 10A and the back surface 10B of the panel 10 can be made equal.

As described above, according to the panel 10, the hot and cold water pipes 11 form one system of pipeline, and therefore the surface 10A
Although the amount of heat radiation and the amount of heat absorption on each of the back surface 10B and the back surface 10B cannot be controlled individually, the panel 10 can be made thin. As a result, a high-quality panel 10 that is thin and has a double-sided radiation function and satisfies the requirements of the boundary wall
Can be configured to shorten the installation period.

(Example 1) As an example of the panel 10, as shown in FIG. 2, a PC panel having a width W of 2,000 mm and a height H of 2,000 mm was used, and an inner diameter of 7 mm was used as a cold / hot water pipe 11. When a cross-linked polyethylene pipe having an outer diameter of 10 mm is piped for about 27 m and a wire mesh 12 formed of a wire having a diameter of 6 mm is laid, the thickness D1 (see FIG. 3) of the panel 10 may be 90 mm. did it. In this case, the concrete thickness W11 between the hot / cold water pipe 11 and the front surface 10A (the pipe cover thickness on the front surface side) and the concrete thickness W12 between the cold / hot water pipe 11 and the back surface 10B (the pipe cover thickness on the back surface side) W12 are It was 40 mm.
Then, under the environment of room temperature of 26 ° C., the panel 10
The cold water of 13 ° C is fed to the cold / hot water pipe 11 of 2.5 (l / m
In), the amount of heat radiated from both sides is 360
(Kcal / h), surface 10A is 18.8 to 19.5 ° C.
And the temperature of the back surface 10B was 19.5 to 20.0 ° C.

(Second Embodiment) FIG. 4 shows a second embodiment of the present invention.
The basic configuration of the panel 20 of this embodiment is shown, and this panel 20 also partitions the left and right rooms R1 and R2 between the floor 1 and the ceiling 2 of the building, similar to the panel 10 in the above-described embodiment.

It is configured by a panel, a heat insulating material 21 is provided in the center of the inside, and cold water or hot water pipes (pipes) 22 and 23 for circulating cold water or hot water on both sides of the heat insulating material 21.
Is embedded.

FIG. 5 shows a specific structure of the panel 20. Each of the cold / hot water pipes 22 and 23 is arranged in the same manner as the cold / hot water pipe 11 in the above-mentioned embodiment.
As a result, separate pipes for circulating cold and warm water are formed. Wire meshes 24 and 25 are arranged outside the cold and hot water pipes 22 and 23, respectively. Similar to the wire mesh 12 of the above-described embodiment, these wire meshes 24 and 25 have a function of reinforcing the panel 20 and at the same time transmitting heat evenly between the hot and cold water pipes 22 and 23 and the entire surface of the panel 20. It has.

To regulate R2 to different temperatures, they can be radiantly cooled or radiantly heated at the same time. That is, the surface 2 of the panel 20 is controlled by separately controlling the temperature and the flow rate of cold water or hot water passing through the cold / hot water pipes 22 and 23.
The temperatures of the rooms R1 and R2 can be individually adjusted by individually setting the amount of heat radiation and the amount of heat absorption in the back surface 20B and 0A.

The surface 20A of the panel 20 has an uneven shape from the viewpoint of preventing the formation of dew condensation during cold radiation operation. That is, when the surface 20A of the panel 20 comes into surface contact with furniture or the like during cold radiation operation, dew condensation may occur on the contact surface. Even if the cold water temperature is controlled so that the temperature of the surface 20A is higher than the dew point in the room, dew condensation may occur when furniture or the like is in contact with the surface 20A for a long time.

On the other hand, in the panel 20, the surface 20A is finished in a concavo-convex shape such as ribs or corrugations in consideration of such a situation, so that a gap with furniture or the like can be formed and air retention can be prevented. It is possible to prevent the occurrence of dew condensation. Further, by making the surface 20A uneven, the heat exchange area becomes large, and especially when used together with an air conditioner, it is also possible to increase the cooling and heating effect by heat transfer by the air flow near the surface 20A. become.

The irregularities on the surface 20A are
In addition to the finish of A, it can be formed by driving a metal. Further, the back surface 20B may also have an uneven shape. Further, when the dew condensation that has occurred inside the panel 20 oozes out, in order to deal with the fact that it causes mold, etc., the front surface 20A and the back surface 20B

Example 2 As an example of the panel 20, the width W is 2,000 mm and the height H is 2,000 mm.
A PC panel having a thickness D2 (see FIG. 5) of 165 mm is provided with a heat insulating material 21 having a thickness of 15 mm, and hot and cold water pipes 22 and 23 are piped with crosslinked polyethylene pipes each having an inner diameter of 7 mm and an outer diameter of 10 mm by about 27 m, and a diameter. The wire mesh 12 formed by 6 mm wire was arranged. The concrete thickness (pipe cover thickness on the surface side) W21 between the hot and cold water pipe 22 and the undulating surface 20A is 24.5 to 32.5.
mm, the concrete thickness between the hot and cold water pipe 23 and the back surface 20B (pipe back cover thickness on the back surface side) W22 is 32.5 mm.
And

When the cold water of 13 ° C. is circulated at a flow rate of 2.5 (l / min) in the cold / hot water pipe 22 of the panel 20 having such a structure under the environment of room temperature of 26 ° C.,
The heat radiation amount is 230 (kcal / h), the concave portion of the surface 20A is 17.6 to 18.1 ° C., and the convex portion is 18.3 to 18.8.

The temperature was increased by 0.7 ° C from the convex portion (the pipe cover thickness W21 was 32.5 mm). Also, when cold water is similarly circulated through the hot / cold water pipe 23, the back surface 20B has 18.1-1.
It reached 8.6 ° C. Further, the panel 20 has a doubled pipe length to be embedded as compared with the panel 10 of the above-described embodiment, and since the heat exchange area is increased due to the uneven surface 20A, the heat radiation amount is about 25%. It got bigger.

(Third Embodiment) The partition panel of the present invention is not limited by the installation form.
It can also be configured as a fireproof wall with fireproof performance forming a fireproof compartment. By using a reinforced concrete panel as the PC panel of the main body of the partition panel of the present invention, for example, the panel 10 of the first embodiment can be set to a thickness necessary for fire resistance performance to form a fire wall. In that case, since the panel 10 is made thick, the rise time until the surface temperature reaches the set temperature by the radiant cooling and heating function takes a long time, but there is no large change in the basic ability.
