Description

[Technical Field]

[0001] The present invention relates to a silent room structure. [Background technology]

[0002] Patent Document 1 discloses a technology related to a ceiling radiant air conditioner in which a heat radiation pipe for circulating a heating or cooling medium is arranged in the ceiling of the room to be air-conditioned. In this prior art, the ceiling radiant air conditioner has the heat radiation pipe arranged in an exposed state in the space below the upper slab that forms the room to be air-conditioned. In addition, a lattice-like body is arranged below the heat radiation pipe to form a boundary equivalent to the ceiling in the ceiling radiant air conditioner, and sound-absorbing material is attached to the underside of the upper slab.

[0003] Patent Document 2 discloses a technology related to an air conditioning system that conditions a target area via a radiating member. In this prior art, the air conditioning system includes a radiating member disposed above the target area and facing the target area, and a heat transfer pipe disposed along the radiating member. The target area is conditioned by circulating a heat transfer medium through the heat transfer pipe. The radiating member is formed of a long, elongated member having at least a bottom plate extending longitudinally and side plate portions rising from the bottom plate portion, with the top or sides open. The heat transfer pipe is placed on the top surface of the bottom plate portion of the radiating member. Multiple radiating members are disposed above the target area, with the side plate portions exposed to the target area and with a gap between the target area and the ceiling space.

[0004] [Patent Document 1] Publication No. 4-38175 [Patent Document 2] Japanese Patent Application Publication No. 2019-117023 Summary of the Invention [Problem to be solved by the invention]

[0005] Radiant heating and cooling systems produce little noise because they do not produce fan noise or wind noise. However, radiant heating and cooling systems often use radiant panels that are installed on the ceiling, making them part of the ceiling, and in such configurations, sound inside the room reverberates from the radiant panels that make up the ceiling.

[0006] In view of the above, an object of the present invention is to improve the noise reduction performance of a noise-reducing room that uses radiant heating and cooling. [Means for solving the problem]

[0007] The first aspect is a silent room structure comprising a silent room nested in a soundproof space and having sound-absorbing material on at least the ceiling, and a plurality of radiating members spaced apart from the sound-absorbing material and spaced apart from each other in the horizontal direction, with heat medium pipes through which a heat medium flows.

[0008] In the silent chamber structure of the first aspect, the silent chamber is nested in the sound-insulating space, so that the sound insulation is high and the intrusion of sound from outside the silent chamber is reduced compared to when the silent chamber is not nested.

[0009] The interior of the silent room is cooled or heated by a plurality of radiating members provided in the silent room and fitted with heat transfer medium pipes through which a heat transfer medium flows. The radiating members do not use fans, so no fan operation noise or wind noise is generated.

[0010] Furthermore, since the radiating members are installed at a distance from the sound-absorbing material on the ceiling, the sound-absorbing area of ​​the sound-absorbing material on the ceiling is secured. Some of the sound generated in the quiet room enters the gap between the radiating members and the ceiling through the horizontal gaps between the radiating members and is absorbed by the sound-absorbing material on the ceiling.

[0011] Therefore, the noise reduction performance of a quiet room that uses radiant heating and cooling is improved.

[0012] A second aspect is the silent chamber structure according to the first aspect, wherein the lower surface of the radiation member is formed with irregularities.

[0013] In the silent room structure of the second aspect, by forming an uneven surface on the underside of the radiation member, the radiation area is secured while flutter echoes caused by sound generated in the silent room being reflected back and forth between the underside of the radiation member and the floor are reduced, thereby further improving the noise reduction performance of the silent room that uses radiation heating and cooling.

[0014] A third aspect is the silent chamber structure according to the first or second aspect, wherein the lower surface of the radiation member is inclined with respect to the floor surface.

[0015] In the silent room structure of the third aspect, the underside of the radiation member is inclined relative to the floor surface, thereby ensuring a sufficient radiation area while reducing flutter echoes that occur when sound generated in the silent room is reflected back and forth between the underside of the radiation member and the floor surface. This further improves the noise reduction performance of the silent room that uses radiation heating and cooling. [Effects of the Invention]

[0016] According to the present invention, it is possible to improve the noise reduction performance of a noise-reducing room that uses radiant heating and cooling. [Brief explanation of the drawings]

[Figure 5] FIG. 3 is a cross-sectional view of a modified silent chamber structure corresponding to FIG. 2. DETAILED DESCRIPTION OF THE INVENTION

[0018] <Embodiment> A silent chamber structure according to one embodiment of the present invention will now be described.

[0019] [Overall configuration] First, we will explain a building to which a silent room structure is applied. The two directions that intersect at right angles to the horizontal direction are the X direction and the Y direction, and are indicated by arrows X and Y, respectively. The vertical direction that is perpendicular to the X direction and the Y direction is the Z direction, and is indicated by arrow Z.

[0020] As shown in FIGS. 1 and 4, the silent room structure 100 is configured to include a silent room 110 provided in a building 10 and a plurality of radiation members 150 provided in the silent room 110.

[0021] As shown in Fig. 4, the silent room 110 is provided in a nested structure within the soundproof space 12 of the building 10. In this embodiment, the soundproof space 12 is surrounded by walls 20 and slabs 22, 24 that constitute the skeleton of the building 10. The soundproof space 12 is a space surrounded by soundproofing materials such as the walls 20 and slabs 22, 24 that block or reduce sound propagating through the air. From another perspective, the soundproof space 12 is a space surrounded by the walls 20 and slabs 22, 24, etc., in which sound leakage from within the space to the outside and sound intrusion from the outside into the space are blocked or reduced.

[0022] The silent room 110 of this embodiment is configured to have a wall portion 120, a ceiling portion 122, and a floor portion 124. In the silent room 110, the wall portion 120, the ceiling portion 122, and the floor portion 124 are provided in the soundproof space 12 with a gap between them and the walls 20 and slabs 22, 24. Note that soundproofing material such as glass wool may be provided between the wall portion 120, the ceiling portion 122, and the floor portion 124 and the walls 20 and slabs 22, 24.

[0023] In this embodiment, the ceiling 122 of the silent room 110 has a vibration-isolating suspended ceiling structure connected to the upper slab 22 with vibration-isolating hangers 102 equipped with vibration-isolating rubber. The floor 124 of the silent room 110 is provided on vibration-isolating members 104 installed on the lower slab 24, forming a floating floor structure.

[0024] Note that the nested structure in which the silent room 110 shown in Fig. 4 is provided within the soundproof space 12 of the building 10 is an example and is not limited to this. In addition, the vibration-isolating suspended ceiling structure and floating floor structure shown in Fig. 4 are also examples and are not limited to these.

[0025] As shown in Fig. 1, an opening 52 for an RA duct 50 and an opening 62 for an SOA duct 60 of an outdoor air-conditioning unit (not shown) are provided in a ceiling portion 122 of the quiet room 110. Also, as shown in Fig. 2, a sound-absorbing material 70 is provided on a lower surface 122A of the ceiling portion 122 and an inner surface 120A of the wall portion 120. Note that, as shown in Fig. 1, the sound-absorbing material 70 of the ceiling portion 122 is not provided in the areas of the openings 52 and 62.

[0026] As shown in Figures 1 and 4, the interior of the silent room 110 is cooled and heated by a radiant air conditioner 140. The radiant air conditioner 140 has a plurality of radiating members 150 to which heat medium pipes 200 (see Figure 1) through which a heat medium flows are piped. A plurality of radiating members 150 are provided at intervals below the sound-absorbing material 70 on the ceiling 122 of the silent room 110. In this embodiment, as shown in Figure 4, the plurality of radiating members 150 are each suspended from the ceiling 122 by a suspension member 130, but the present invention is not limited to this.

[0027] As shown in Fig. 3, the radiation members 150 in this embodiment have rectangular outer shapes in a plan view, and are provided with a gap L between them in the lateral direction (see also Figs. 1 and 4). Note that, as shown in Fig. 1, in this embodiment, the opening 62 of the SOA duct 60 described above is arranged at a position overlapping the gap L between the radiation members 150 in a plan view.

[0028] 2, the radiation member 150 of this embodiment is made of a plate-like member with high thermal conductivity, which is made of a metallic material such as aluminum or steel, and has a structure in which first grooves 152 that open on the upper side along the X direction and second grooves 154 that open on the lower side are alternately arranged in the Y direction. From another perspective, the lower surface 150A of the radiation member 150 is formed with recesses 158 (second grooves 154) and downwardly facing protrusions 156 (first grooves 152). In other words, the radiation member 150 has unevenness formed on the lower surface 150A. Note that in figures other than FIG. 2 and FIG. 4 described later, the radiation member 150 is small, so the unevenness of the lower surface 150A is not shown.

[0029] Furthermore, a plurality of through holes 155 are formed in the lower surface 150A of the radiation member 150 at a location corresponding to the bottom surface of the second groove portion 154 (recess 158).

[0030] As shown in FIG. 3, the heat transfer pipe 200 is configured to include a main piping section 202 that is piped along the X direction and spaced apart in the Y direction, secondary piping sections 204 that are piped along the Y direction on both sides of the main piping section 202 in the X direction, a connecting pipe section 206 that connects the secondary piping sections 204 of adjacent radiation members 150, a supply pipe section 210, and a discharge pipe section 212.

[0031] The heat medium supplied from the supply pipe section 210 flows through the sub-piping section 204 and the main piping section 202 connected to the radiation member 150, and then flows through the sub-piping section 204 and the main piping section 202 of the adjacent radiation member 150 via the connecting pipe section 206 (see also FIG. 1). In this way, the heat medium flows sequentially through the radiation member 150 and is then discharged from the discharge pipe section 212 (see also FIG. 1).

[0032] As shown in FIG. 1, the heat transfer medium is supplied from the outward path 220 to the supply pipe section 210 by the pump 144, and after flowing through the sub-pipe section 204 and the main pipe section 202 which are connected to the radiation member 150 as described above, it is sent from the discharge pipe section 212 to the return path 222, passes through the heat exchanger 145, and is returned to the pump 144.

[0033] In the heat exchanger 145, the heat medium is subjected to heat exchange and other processes with a heat transfer medium (such as hot or cold water) supplied from a heat source device or the like (not shown).

[0034] The piping structures shown in FIGS. 1 and 3 are merely examples and are not limited to these.

[0035] [Action and effect] Next, the operation and effects of this embodiment will be described.

[0036] The silent chamber 110 of this embodiment is provided in a nested structure in the soundproof space 12, so that it has high sound insulation properties and reduces the intrusion of sound from outside the silent chamber 110 compared to a case without a nested structure.

[0037] Furthermore, the inside of the silent chamber 110 is heated or cooled by radiation from a plurality of radiation members 150 that are provided in the silent chamber 110 and have heat medium pipes 200 through which a heat medium flows. The radiation members 150 do not use a fan, so no fan operation noise or wind noise is generated.

[0038] Furthermore, the radiating member 150 is provided at a distance from the sound absorbing material 70 on the ceiling portion 122, ensuring a sound absorbing area of ​​the sound absorbing material 70 provided on the ceiling portion 122. Some of the sound generated inside the silent room 110 enters between the radiating member 150 and the ceiling portion 122 through the gap L between the radiating members 150, and is absorbed by the sound absorbing material 70.

[0039] Furthermore, a plurality of through holes 155 are formed in the portion of the radiation member 150 corresponding to the bottom surface of the second groove portion 154 (recess 158). Therefore, part of the sound generated in the silent chamber 110 also enters between the radiation member 150 and the ceiling portion 122 through the through holes 155 and is absorbed by the sound absorbing material 70.

[0040] Therefore, the noise reduction performance of the quiet room 110, which uses radiation heating and cooling, is improved.

[0041] Furthermore, by forming unevenness on the lower surface 150A of the radiation member 150, the radiation area is ensured while flutter echoes caused by sound generated in the silent room 110 being reflected back and forth between the lower surface 150A of the radiation member 150 and the floor surface 124A of the floor part 124 are reduced. Therefore, the noise reduction performance of the silent room 110, which performs heating and cooling by a radiation method, is further improved.

[0042] In addition, in plan view, the air processed by the radiation component above the radiating member 150 is gently blown down by the airflow from the opening 62 of the SOA duct 60, which is positioned at a position overlapping with the gap L between the radiating members 150.

[0043] [Variations] Next, a modification of this embodiment will be described.

[0044] In a modified silent room structure 109 shown in FIG. 5, a radiation member 150 is provided such that a lower surface 150A is inclined with respect to the floor surface 124A (see FIG. 1).

[0045] Therefore, flutter echoes caused by sound generated in the silent room 110 being reflected back and forth between the underside 150A of the radiating member 150 and the floor surface 124A (see FIG. 1) are further reduced while the radiation area of ​​the radiating member 150 is secured. This further improves the noise reduction performance of the silent room 110, which performs heating and cooling by a radiation method.

[0046] <Other> The present invention is not limited to the above embodiment.

[0047] For example, in the above embodiment, the lower surface 150A of the radiation member 150 is formed with irregularities, but this is not limiting. The lower surface 150A of the radiation member 150 may be a flat surface.

[0048] In the above embodiment, the radiation member 150 is formed of a plate-like member and has a rectangular outer shape in a plan view, but this is not limiting. For example, the radiation member may be in the shape of a long strip. Furthermore, the long strip-like radiation members may be arranged in a lattice pattern in a plan view.

[0049] Furthermore, the present invention can be embodied in various forms without departing from the spirit of the present invention. [Explanation of symbols]
