DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling radiant cooling / heating panel capable of exhibiting a sound absorbing effect and securing fireproofness.

[0002]

2. Description of the Related Art As a conventional ceiling radiation heating panel, for example, there is one shown in FIG. The box-shaped radiation panel 1 has a plurality of sound-absorbing holes 2 penetrating the surface thereof. If the radiant panel 1 is installed on the ceiling side, the sound in the room is absorbed by the sound absorbing holes 2 and is hardly reflected, so that the sound absorbing effect can be enhanced. On the back surface of the radiation panel 1, heat exchange pipes 3 are arranged at an appropriate pitch. As the heat exchange pipe 3, although not specifically shown, a type in which one pipe is meandering,
There is a type in which multiple pipes are arranged in parallel.

[0003] A heat insulating material 4 is provided so as to cover the heat exchange pipes 3. The heat insulating material 4 is for preventing the heat inside the ceiling where the temperature changes drastically from being transmitted to the heat exchange pipe 3 and preventing the heat of the heat exchange pipe from escaping to the space above the ceiling. Radiant panel 1 thus constructed
Is installed on the ceiling side, and the heat exchange pipe 3 is connected to a pump and a tank (not shown). Heating is performed by flowing a warm fluid through the heat exchange pipe 3.

[0004]

In recent years, heat exchange pipes 3
Is often formed of resin, for example, polypropylene or the like. This is because the processing is simple, and cost reduction and weight reduction can be achieved. However, in the ceiling radiant heating panel of the conventional example, in order to enhance the sound absorbing effect, a plurality of sound absorbing holes 2 are formed on the surface of the radiant panel 1.
Is formed. As a result, when a fire occurs, the following problem may occur. That is,
When a fire occurs, the fire enters the radiant panel 1 through the sound absorbing hole and ignites the heat exchange pipe 3.

[0005] Even without direct ignition, the heat causes the heat exchange pipe 3 made of polypropylene to melt. For this reason, there is a danger that the heated polypropylene drops from the sound absorbing holes 2 on the surface of the radiation panel 1. In addition, since this polypropylene is easily burnt, if it drips in a ignited state, the floor may be burned and the area around the fire may be sped up. An object of the present invention is to provide a ceiling radiation cooling / heating panel which can form a heat exchange pipe irrespective of a material, and which can ensure a soundproofing effect and a fireproof property.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a radiant panel, a plurality of sound absorbing holes formed through the surface of the radiant panel, a heat exchange pipe disposed on the back of the radiant panel, and a heat exchange pipe. It is assumed that the radiant panel is provided on the ceiling, and the radiant panel is installed on the ceiling, and a fluid is passed through the heat exchange pipe to perform cooling and heating. The first invention is characterized in that a noncombustible sheet material or a noncombustible plate material is interposed between the back surface of the radiation panel and the heat exchange pipe.

According to a second aspect of the present invention, in the first aspect, a non-combustible plate material is used in which a cross section cut in the width direction has a wavy shape in which peaks and valleys are repeated. It is characterized in that it is arranged on the back side of the panel and the pipes arranged in a plurality of rows are each laid in a valley. The third invention is characterized in that, in the second invention, a sound absorbing hole is formed near the peak of the mountain. The fourth invention is characterized in that, in the third invention, the height of the peak is higher than that of the pipe in a state where the pipe is laid in the valley. The fifth invention is characterized in that in the first to fourth inventions, a non-combustible heat insulating material such as glass wool is used as the heat insulating material.

[0008]

1 and 2 show a first embodiment of a ceiling radiant heating panel according to the present invention. The radiant panel 1 is formed of a metal such as aluminum or iron, gypsum board, concrete, or the like, and has a plurality of sound absorbing holes 2 formed on the surface thereof as in the conventional example. Then, a heat exchange pipe 3 made of polypropylene is arranged on the back surface of the radiant panel 1, and at this time, a noncombustible sheet material 5 is attached to the back surface of the radiant panel 1. Therefore, the non-combustible sheet material 5 is interposed between the back surface of the radiation panel 1 and the heat exchange pipe 3. Here, a ceramic sheet is used as the non-combustible sheet material 5. The ceramic sheet has high thermal conductivity as well as nonflammability, so that the presence of the ceramic sheet does not impair the heating effect. In addition, since it has good hygroscopicity, it is possible to prevent moisture from being trapped in the radiation panel 1.

If the ceramic sheet is made, for example, in a wool shape, sound can be absorbed there and the soundproofing effect can be enhanced. Moreover, in this case, friction occurs between the heat exchange pipe 1 and the non-combustible sheet material 5, so that the heat exchange pipe 1 is hardly displaced. Therefore, the positioning of the heat exchange pipe 3 can be performed more easily than when the heat exchange pipe 3 is directly installed on the back surface of the radiation panel 1.
Further, a heat insulating material 4 is provided so as to cover the heat exchange pipe 3. Here, glass wool is used as the heat insulating material 4. Glass wool has not only high heat insulating properties but also nonflammability. In addition, since it has a fibrous shape, a further sound absorbing effect is exhibited in combination with the sound absorbing hole 2.

In the ceiling radiant heating panel of the first embodiment as described above, even if a fire occurs and the heat exchange pipe 3 is melted, the melted polypropylene is interposed by interposing the non-combustible sheet material 5. It is possible to prevent dripping from the sound absorbing hole 2. Therefore, the high-temperature polypropylene can prevent a person from being burned and the area around the fire from becoming fast. In addition, the above glass wool,
When provided so as to be pressed against the heat exchange pipe 3 already arranged, a gap 6 is formed between the glass wool and the heat exchange pipe 3. Therefore, even if the heat exchange pipe 3 melts, it only accumulates in the gap 6. As shown in FIG. 2, if the end of the non-combustible sheet material 5 is attached to the side of the back surface of the radiant panel 1, the melted polypropylene can be disposed between the back surface of the radiant panel 1 and the non-combustible sheet material 5. It is more effective without penetrating into

In the second embodiment shown in FIGS. 3 to 6, a noncombustible plate 7 is interposed between the glass wool and the heat exchange pipe 3 instead of the noncombustible sheet 5. The non-combustible plate member 7 is made of a metal plate such as aluminum, and as shown in FIG. 3B, the cross section cut in the width direction has a wave shape in which peaks 8 and valleys 9 are repeated. As shown in FIG. 4, the non-combustible plate member 7 is provided such that its valley 9 is in contact with the rear surface side of the radiation panel 1. Each of the heat exchange pipes 3 arranged in a plurality of rows is laid in these valleys 9. Therefore, the heat exchange pipe 3
Will be neatly aligned along these valleys 9. Further, a glass wool is provided as a heat insulating material 4 on the mountain 8 side of the noncombustible plate member 7 as in the first embodiment.

In the ceiling radiant heating panel of the second embodiment as described above, even if a fire occurs and the fire tries to enter the radiant panel 1 through the sound absorbing hole 2, the fire is cut off by the non-combustible plate member 7. Therefore, there is no direct ignition of the heat exchange pipe 3. Further, even if the heat exchange pipe 3 made of polypropylene melts out due to heat, the melted polypropylene only accumulates in the valley 9. Therefore, it does not drip from the sound absorbing hole 2, and it is possible to prevent a person from being burned or the area around the fire from being quickly fired by the high-temperature polypropylene.

Further, a space 8a behind the sound absorbing hole 2 and the mountain 8 is formed.
In the place where the sound energy is matched, the sound absorbed by the sound absorbing hole 2 is cut off by the non-combustible plate member 7. Therefore, the sound is not transmitted to the ceiling and the room does not get stuck in the next room or the room on the upper floor. As described above, not only the sound absorbing effect but also the sound insulating effect can be obtained, and it is possible to optimize the ceiling material. Furthermore, noncombustible plate material 7
Is formed into a wave shape in which the peaks 8 and the valleys 9 are repeated, so that the heat exchange pipes 3 can be aligned neatly, and uneven temperature hardly occurs. In addition, the corrugated shape can increase the surface area, easily release heat, and improve thermal efficiency.

As shown in FIG. 5, a sound absorbing hole 10 may be formed in the vicinity of the peak of the mountain 8 of the noncombustible plate member 7.
In this way, when the sound absorbing hole 10 is not formed, the sound absorbing effect is exhibited, but the sound in the space 8a behind the mountain 8 is absorbed and combined with the sound absorbing hole 2 formed in the radiation panel 1. , Will exhibit a further sound absorbing effect. However, in this case, it is desirable that the height H of the peak 8 be higher than the heat exchange pipe 3 with the heat exchange pipe 3 laid in the valley 9.

That is, by forming the sound absorbing holes 10 in the non-combustible plate 7, it is conceivable that the fire that has entered the radiant panel 1 through the sound absorbing holes 2 will further enter through the sound absorbing holes 10. At this time, if the height H of the peak 8 is set higher than the heat exchange pipe 3, the fire does not approach the heat exchange pipe 3 and it is possible to avoid ignition. The shape of the wave of the noncombustible plate 7 is not limited to a trapezoid. For example, as shown in FIG.
If the curvature is made substantially the same as the curvature of the heat exchange pipe 3, the contact area with the heat exchange pipe 3 can be secured by that much, and the thermal efficiency can be improved. In the first and second embodiments described above, the heating panel has been described. However, cooling may be performed by flowing a cold fluid through the heat exchange pipe 3.

[0016]

According to the first aspect of the invention, in order to reduce the cost and weight, even if the heat exchange pipe is made of a resin such as polypropylene, it is possible to secure the fire resistance. That is, when a fire occurs, the heat exchange pipe melts out. However, since the non-combustible sheet material is interposed, it is possible to prevent the melted polypropylene from dripping from the sound absorbing hole. Therefore, the high-temperature polypropylene can prevent a person from being burned or the area around the fire from being burned quickly. In this way, the heat exchange pipe can be formed irrespective of the material, and it is possible to secure the fireproof property while exhibiting the sound absorbing effect.

According to the second invention, in the first invention, even if a fire occurs and the fire tries to enter the radiant panel from the sound absorbing hole, the fire is cut off by the non-combustible plate material. There is no ignition of the heat exchange pipe.
Further, even if the heat exchange pipe melts out due to heat, the melted heat exchange pipe only accumulates in the valley. Therefore, it is possible to prevent a person from getting burned or to get around the fire fast by the high-temperature polypropylene without dripping from the sound absorbing hole.

Further, in a place where the sound absorbing hole and the space behind the mountain coincide, the sound absorbed by the sound absorbing hole is cut off by the non-combustible plate. Therefore, the sound is transmitted to the inside of the ceiling, so that the next room or the room on the upper floor does not get stuck. As described above, not only the sound absorbing effect but also the sound insulating effect can be obtained, and it is possible to optimize the ceiling material. Furthermore, by forming the non-combustible plate material into a wave shape in which peaks and valleys are repeated, the heat exchange pipes can be aligned neatly, and temperature unevenness is less likely to occur. In addition, the corrugated shape can increase the surface area, easily release heat, and improve thermal efficiency.

According to the third invention, in the second invention, even the sound in the space behind the mountain can be absorbed, so that a further sound absorbing effect is exhibited in combination with the sound absorbing holes formed in the radiant panel. According to the fourth invention, in the third invention, even if the fire that has entered the radiant panel from the sound absorbing hole further enters from the sound absorbing hole of the non-combustible plate, the fire does not approach the heat exchange pipe, It can avoid ignition. According to the fifth aspect, in the first to fourth aspects, the non-combustible heat insulating material is used, so that the flame resistance can be improved. And, for example, if fibrous glass wool is used, the sound will be absorbed there as well, and in combination with the sound absorbing holes, a further sound absorbing effect will be exhibited.
