Description

  The present invention relates to a ceiling radiation system that is installed on a ceiling and cools at least a room, and particularly relates to a ceiling radiation system that cools a room by radiation.

  Currently, the mainstream cooling system cools the air sucked from the room or the outside and supplies it to the room, which is unnatural to the human body because the room temperature does not correspond to the amount of radiant heat. Therefore, a cooling system has been developed that cools a room by heat radiation by flowing cold water through a heat radiation tube disposed in the room.

  Such a cooling system includes a wall-shaped radiation system in which heat radiation tubes are arranged in a wall shape and a drain member for receiving condensed water is disposed below, or a ceiling radiation device in which heat radiation tubes are disposed horizontally in the vicinity of the ceiling surface. There is a system.

  However, since the wall-shaped radiation system needs to be arranged indoors, the indoor space is consumed. Of course, since the cooling effect changes depending on the distance from the wall-shaped radiation system, it is difficult to cool the room uniformly.

  On the other hand, the ceiling radiation system does not consume indoor space and can cool the room substantially uniformly. However, in the ceiling radiation system, when cold water that has been sufficiently cooled is caused to flow into the heat radiation tube, condensation occurs and water drops fall into the room.

  For this reason, in some ceiling radiation systems, the temperature of the chilled water is controlled within a range where condensation does not occur, but this cannot sufficiently cool the room. Also, in some ceiling radiation systems, a single tray is placed below the multiple heat radiation tubes, and water droplets are condensed on the tray, but this prevents the cooling effect of the multiple heat radiation tubes from being affected by the tray. Will be.

  Therefore, the present inventors have invented and applied for a ceiling radiation system that has solved the above-described problems. The ceiling radiation system includes a plurality of heat radiation tubes, a plurality of heat radiation plates, a plurality of drain members, and the like.

  The plurality of heat radiation tubes are formed in an elongated shape, and are arranged in parallel below the ceiling surface in parallel in the front-rear direction and the longitudinal direction at predetermined intervals in the left-right direction. The plurality of heat radiating plates are individually formed downward from a substantially left-right position on the outer surface of each of the plurality of heat radiating tubes. The plurality of drain members are formed in an elongated bowl shape having a width wider than that of the heat radiating tube and having an upper surface opened, and are individually arranged substantially in parallel below the heat radiating tube.

  In this ceiling radiation system, when cold water flows into a plurality of heat radiation tubes, the room is cooled by the heat radiation of the heat radiation tubes and the heat radiating plate. Since the heat radiating plates are mounted on both sides of each of the plurality of heat radiation tubes, the heat radiation performance of the heat radiation tubes can be improved by the heat radiation plates.

  When sufficiently cooled cold water is flowed, water droplets are condensed on the surfaces of the heat radiation tube and the heat radiating plate. However, since the drain member is located below each of the heat radiation tube and the heat radiating plate, water droplets condensed on the heat radiation tube and the heat radiating plate can be reliably collected by the drain member.

For this reason, it is possible to sufficiently cool the room by flowing cold water sufficiently cooled in the heat radiation tube. In addition, since the air cooled by the heat radiation tube and the heat radiating plate can be circulated into the room through the gap between the drain members, the room can be cooled with good efficiency (see, for example, Patent Document 1).
JP 2006-112742 A

  In the above-described ceiling radiation system of Patent Document 1, it is assumed that cold water is supplied to one end of each of a plurality of heat radiation tubes arranged in parallel, and drainage is recovered from the other end. For this reason, it is necessary to form a cold water supply mechanism and a recovery mechanism on both sides of the ceiling radiation system, and the piping thereof becomes complicated.

  Further, in the above-described ceiling radiation system, when the ceiling has a large area, the heat radiation tube and the drain member are long. In that case, the heat radiation tube or the drain member may be bent due to its own weight. In order to prevent this, the heat radiation tube is formed thick to ensure mechanical strength, or the number of locations where the heat radiation tube is connected to the ceiling surface is increased.

  Furthermore, the drain member is preferably inclined for drainage. However, inclining a long drain member is not preferable because one end on the lower side thereof is positioned significantly below the ceiling surface.

  The present invention has been made in view of the above-described problems, and can easily prevent the heat radiation tube and the drain member from bending due to its own weight, and there is no portion positioned significantly below the ceiling surface. An object of the present invention is to provide a ceiling radiation system in which piping is easy.

  The ceiling radiation system of the present invention is a ceiling radiation system that is arranged below the indoor ceiling surface and performs at least cooling by heat radiation, and has a plurality of right side heat radiation tubes in which cold water flows in a shape elongated in the left-right direction. A plurality of right-side drain members that hold water drops falling from the right-side heat radiation tube in a shape elongated in the left-right direction, and a plurality of right-side heat radiation tubes and a plurality of right-side drain members are inclined in the front-rear direction with the right side facing upward Right-side support mechanism that supports in parallel, a plurality of left-side heat radiation tubes that are elongated in the left-right direction and at least cold water flows, and a plurality of left-side drains that are elongated in the left-right direction and hold water drops falling from the left-side heat radiation tubes A left side support mechanism that supports a member, a plurality of left heat radiation tubes, and a plurality of left side drain members in parallel in the front-rear direction in an inclined state with the left side facing upward; A central cover member into which the left ends of the right side heat radiation tube and the plurality of right side drain members are inserted and a plurality of left side heat radiation tubes and the right ends of the plurality of left side drain members are inserted; A central water supply member for flowing at least cold water to the plurality of right side heat radiation tubes and the plurality of left side heat radiation tubes, and a plurality of right side drain members and a plurality of left side drains disposed inside the central cover member. A central drainage member for discharging drainage from the member.

  Therefore, in the ceiling radiation system of the present invention, the plurality of right side heat radiation tubes and the plurality of right side drain members are supported in parallel in the front-rear direction in a tilted state where the right side is upward by the right side support mechanism, and The radiation tube and the plurality of left drain members are supported in parallel in the front-rear direction in a tilted state in which the left side is upward by the left side support mechanism. Since cold water flows from the central water supply member to the plurality of right-side heat radiation tubes and the plurality of left-side heat radiation tubes supported in this manner, the radiation of the plurality of right-side heat radiation tubes and the plurality of left-side heat radiation tubes The surroundings are cooled. At this time, even if condensation occurs on the surfaces of the plurality of right side heat radiation tubes and the plurality of left side heat radiation tubes and the water drops fall, the water droplets are held by the plurality of right side drain members and the plurality of left side drain members. Is done. Drainage of the plurality of right side drain members and the plurality of left side drain members is discharged by the central drainage member.

  In the ceiling radiation system as described above, a plurality of right side heat radiation tubes, a plurality of right side drain members, and a right side support mechanism form a right side radiation unit, and a plurality of left side heat radiation tubes and a plurality of left side drain members. The left radiation unit is formed by the left support mechanism, the central piping unit is formed by the central cover member, the central water supply member, and the central drainage member, and the right radiation unit and the left radiation unit are combined into the central piping unit. It may be detachably attached.

  In the ceiling radiation system as described above, the right side radiation unit and the left side radiation unit may be formed in the same symmetrical structure.

  In the ceiling radiation system as described above, a plurality of central piping units may be sequentially connected in the longitudinal direction.

  The ceiling radiation system as described above further includes an internal cleaning member that is movable within the central drainage member, and an internal cleaning mechanism that slides the internal cleaning member to clean the inner surface of the central drainage member. May be.

  The various components of the present invention do not necessarily have to be independent of each other. A plurality of components are formed as a single member, and a single component is formed of a plurality of members. It may be that a certain component is a part of another component, a part of a certain component overlaps with a part of another component, or the like.

  In the present invention, the front-rear and left-right directions are defined, but this is defined for convenience in order to briefly explain the relative relationship of the components of the present invention. It does not limit the direction of time or use.

  In the ceiling radiation system of the present invention, the plurality of right heat radiation tubes and the plurality of right drain members are supported in parallel in the front-rear direction in a tilted state where the right side is upward by the right support mechanism, and the plurality of left heat radiation tubes And the plurality of left drain members are supported in parallel in the front-rear direction in a tilted state in which the left side is upward by the left side support mechanism. Since cold water flows from the central water supply member to the plurality of right-side heat radiation tubes and the plurality of left-side heat radiation tubes supported in this manner, the radiation of the plurality of right-side heat radiation tubes and the plurality of left-side heat radiation tubes The surroundings can be cooled. At this time, even if condensation occurs on the surfaces of the plurality of right side heat radiation tubes and the plurality of left side heat radiation tubes and the water drops fall, the water droplets are held by the plurality of right side drain members and the plurality of left side drain members. Then, it can be drained by the central drainage member. In addition, the entire system can be formed symmetrically, and the central water supply member and the central drainage member are concentrated in the center thereof, so that the piping and the like can be simplified. Furthermore, since the heat radiation tube and the drain member are separated on the left and right, the total length of each can be made substantially half of that of the prior art. For this reason, it is possible to easily prevent the heat radiation tube and the drain member from being bent due to their own weights, and the center cover member needs to be positioned only about half of the conventional level from the ceiling surface.

  An embodiment of the present invention will be described below with reference to FIGS. The ceiling radiation system 1000 according to the present embodiment is disposed below the ceiling surface of the room and performs at least cooling by heat radiation.

  Therefore, as shown in FIGS. 1 to 3, the ceiling radiation system 1000 of the present embodiment has a plurality of right side heat radiation tubes 210 in which cold water flows in a shape elongated in the left-right direction, and a shape elongated in the left-right direction. A plurality of right side drain members 220 that hold water drops falling from the right side heat radiation tube 210, and a plurality of right side heat radiation tubes 210 and a plurality of right side drain members 220 are supported in parallel in the front-rear direction in an inclined state with the right side upward. A right support mechanism 230 that has a shape that is elongated in the left-right direction and a plurality of left heat radiation tubes 310 that flow at least cold water, and a plurality of left-side drains that retain a droplet that is elongated in the left-right direction and falls from the left heat radiation tubes 310. The left side support mechanism 330 that supports the member 320, the plurality of left heat radiation tubes 310, and the plurality of left side drain members 320 in parallel in the front-rear direction in an inclined state in which the left side is upward. The left ends of the plurality of right heat radiation tubes 210 and the plurality of right drain members 220 are inserted in the shape of a box elongated in the front-rear direction, and the right ends of the plurality of left heat radiation tubes 310 and the plurality of left drain members 320 are A central cover member 110 inserted, a central water supply member 120 disposed inside the central cover member 110 and allowing at least cold water to flow through the plurality of right side heat radiation tubes 210 and the plurality of left side heat radiation tubes 310; The central drainage member 130 is disposed inside the cover member 110 and discharges the drainage of the plurality of right side drain members 220 and the plurality of left side drain members 320.

  More specifically, in the ceiling radiation system 1000 of the present embodiment, as shown in FIGS. 4 and 5, the right radiation unit 200 includes a plurality of right heat radiation tubes 210, a plurality of right drain members 220, and a right support mechanism. The left radiation unit 300 is formed by the plurality of left heat radiation tubes 310, the plurality of left drain members 320, and the left support mechanism.

  The central cover unit 110, the central water supply member 120, and the central drainage member 130 form the central piping unit 100, and the right side radiation unit 200 and the left side radiation unit 300 are detachably attached to the central piping unit 100. Yes.

  The right side radiation unit 200 and the left side radiation unit 300 are formed in the same symmetrical structure. For this reason, the right side radiation unit 200 and the left side radiation unit 300 are formed as a common component.

  For example, as shown in FIG. 2, the right side radiation unit 200 and the left side radiation unit 300 each have six right side heat radiation tubes 210 and six left side heat radiation tubes 310, and six right side drain members 220. And six left-side drain members 320.

  The six right-side heat radiation tubes 210 and the six left-side heat radiation tubes 310 are formed in a structure in which one metal tube is bent in a zigzag, and is continuous from the first to the sixth. It is connected to.

  The six right-side drain members 220 and the six left-side drain members 320 are made of, for example, an aluminum channel material whose upper surface is opened, and the six right-side heat radiation tubes 210 and the six left-side heat radiation tubes 310 Individually located below.

  As shown in FIG. 1, the six right heat radiation tubes 210 and the six right drain members 220 are integrally connected by, for example, a right support mechanism 230, and the ceiling surface is in an inclined state in which the right side is upward. Supported below.

  Similarly, the six left heat radiation tubes 310 and the six left drain members 320 are integrally connected by, for example, a left support mechanism 330, and are supported below the ceiling surface in an inclined state in which the left side is upward. The

  The central cover member 110 of the central piping unit 100 is formed in an elongated box shape in the front-rear direction, and is supported below the ceiling surface by the central support mechanism 140 as shown in FIG.

  The center cover member 110 has a slit-like opening hole into which the right-side radiation unit 200 is inserted on the right side, and a slit-like opening hole into which the left-side radiation unit 300 is inserted on the left side.

  As described above, since the right side heat radiation pipe 210 and the left side heat radiation pipe 310 are continuously connected to each other, the central water supply member 120 of the central piping unit 100 is, for example, as shown in FIG. 2 and FIG. In addition, the center cover member 110 includes a pair positioned at the front end and the rear end, and is connected to the first and sixth of the six right heat radiation tubes 210 and the six left heat radiation tubes 310, respectively. .

  For this reason, the central water supply member 120 located at the front end and the rear end of the central piping unit 100 has, for example, a V shape with a predetermined angle as shown in FIG. 1 and a flat surface as shown in FIG. It consists of a deformed tube with a T-shape.

  The central drainage member 130 is also made of, for example, an aluminum channel member having an upper surface opened, and the six right drain members 220 and the six left drain members 320 face the upper surface opening from above. As shown in FIG. 3, for example, the central drain member 130 is in an inclined state with one end being upward, and a drain pipe 131 is connected to the other end on the lower side.

  Furthermore, as shown in FIG. 6, the ceiling radiation system 1000 of the present embodiment includes a cold water generation mechanism 400 that generates cold water, and a plurality of right side heat radiation tubes 210 and a plurality of left side heat radiation tubes 310 that generate the cold water. And a pump device 410 which is a cold water flow mechanism for causing the water to flow.

  The right heat radiation pipe 210 and the left heat radiation pipe 310 are connected to the outdoor underground tank 412 via the central water supply member 120 and the flowing water pipe 411, and the pump device 410 is connected to the flowing water pipe 411. The underground tank 412 is embedded in an outdoor basement with good heat insulation and stores water.

The cold water generating mechanism 400 includes a heat exchanger 401 and a heat pump 402, and a cooling pipe 403 that cools and circulates a refrigerant (not shown) is connected to the heat pump 402.
The cooling pipe 403 communicates with the heat exchanger 401 together with the flowing water pipe 411.

  In the heat exchanger 401, the water flowing through the flowing water pipe 411 is cooled by the refrigerant flowing through the cooling pipe 403. Further, the cooling pipe 403 is also connected to the indoor dehumidifier 430, and in this dehumidifier 430, ambient air is dehumidified by the refrigerant flowing through the cooling pipe 403.

  Further, as described above, the drain pipe 131 of the central drain member 130 is also piped from the room to the outside and is connected to a drain pump (not shown) outside the room. The drainage pump is driven in conjunction with the cold water generation mechanism 400 and the pump device 410.

  In the above configuration, in the ceiling radiation system 1000 of the present embodiment, the water stored in the underground tank 412 is caused to flow through the water flow pipe 411 by the pump device 410 as shown in FIG.

  At this time, the flowing water in the flowing water pipe 411 is cooled by the cold water generating mechanism 400. This cold water is supplied from the flowing water pipe 411 to one of the pair of central water supply members 120 of the central piping unit 100.

  Then, the cold water sequentially flows from the central water supply member 120 through the plurality of right side heat radiation tubes 210 and the plurality of left side heat radiation tubes 310, and is collected from the other central water supply member 120 to the water flow tube 411. As described above, the cold water flows through the plurality of right side heat radiation tubes 210 and the plurality of left side heat radiation tubes 310, whereby the room is cooled by the radiation.

  Further, as described above, water droplets may condense and fall on the surfaces of the right side heat radiation tube 210 and the left side heat radiation tube 310 through which cold water flows. However, the water drops fall on the right drain member 220 and the left drain member 320.

  The water droplets falling on the right side drain member 220 and the left side drain member 320 are collected in the central drainage member 130 of the central piping unit 100, and are sucked and drained from the drainage pipe 131 by a drainage pump, for example.

  Further, in the ceiling radiation system 1000 of the present embodiment, the entire system is formed symmetrically, and the central water supply member 120 and the central drainage member 130 are concentrated at the center thereof. For this reason, the piping etc. can be made simple and the construction is easy.

  Moreover, the central piping unit 100, the right side radiation unit 200, and the left side radiation unit 300 are separately unitized. For this reason, at the construction site, for example, the central piping unit 100, the right side radiation unit 200, and the left side radiation unit 300 may be connected in order under the ceiling surface, and the work is easy.

  Further, as shown in FIG. 2 and the like, the right-side radiation unit 200 and the left-side radiation unit 300 can be a common component having the same structure, so that the productivity of the entire system can be improved.

  Furthermore, since the heat radiation tubes 210 and 310 and the drain members 220 and 320 arranged in an inclined state are separated on the left and right, the overall length of each can be made substantially half of that of the conventional one. For this reason, it is possible to easily prevent the heat radiation tubes 210 and 310 and the drain members 220 and 320 from being bent due to their own weight, and the center cover member 110 only needs to be positioned about half as low as the conventional one.

  Furthermore, since the ceiling radiation system 1000 of this Embodiment also has the dehumidifier 430 arrange | positioned indoors, the humidification by dew condensation does not become a problem. In particular, in the cold water generating mechanism 400 that generates the cold water supplied to the right heat radiation tube 210 and the left heat radiation tube 310, the cooling pipe 403 of the heat pump 402 is also connected to the indoor dehumidifier 430. For this reason, both the production | generation of cold water and indoor dehumidification can be performed with the one heat pump 402. FIG.

  Furthermore, in the ceiling radiation system 1000 of the present embodiment, the plurality of right side heat radiation tubes 210 and the plurality of left side heat radiation tubes 310 are disposed in the vicinity of the indoor ceiling surface, and the dehumidifier 430 is disposed on the indoor floor surface. It is arranged in the vicinity.

  For this reason, the humidity due to condensation on the right side heat radiation tube 210 and the left side heat radiation tube 310 falls from the vicinity of the ceiling surface to the vicinity of the floor surface, and is dehumidified by the dehumidifier 430. Can be executed simultaneously with efficiency.

  The inventor actually made a prototype of the above-described ceiling radiation system 1000 and experimented on the cooling function. As a result, it was confirmed that the room can be cooled to an appropriate temperature even when the outside air is very hot, and that the room temperature can be maintained substantially constant even when the outside air temperature rises and falls.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above embodiment, the right heat radiation tube 210 and the left heat radiation tube 310 are illustrated as simple circular tubes for the sake of simplicity.

  However, such a heat radiation tube can be formed in various shapes in order to improve heat dissipation. For example, the heat radiation tube 500 illustrated in FIG. 7 includes a copper circular tube 510 and an aluminum heat dissipation member 520.

  The heat dissipating member 520 includes a pair of heat dissipating parts 521 and 522 having an open structure and the same shape. The heat dissipating member 520 includes a cylindrical portion 523 that is in close contact with the outer peripheral surface of the circular tube 510, an upper heat dissipating portion 524 that extends upward from both side portions of the cylindrical portion 523 and is joined at the upper end, and also both sides of the cylindrical portion 523. A lower heat radiation portion 525 that extends downward from the portion and is joined at the lower end.

  In this heat radiation tube 500, cold water flows through the copper circular tube 510, and the heat radiation member 520 made of aluminum generates heat radiation by heat conduction. Since the heat dissipating member 520 is formed in a cross-sectional shape that is elongated in the vertical direction, heat radiation can be generated satisfactorily at both sides thereof.

  Nevertheless, since the heat radiating member 520 includes the pair of heat radiating components 521 and 522, it is not necessary to cast the circular tube 510. Moreover, since the pair of heat radiation components 521 and 522 have an open structure with the same shape, it is not necessary to use an expensive drawing material.

  In the above embodiment, the plurality of right side heat radiation tubes 210 and the plurality of left side heat radiation tubes 310 are continuously connected in a structure in which one metal tube is bent zigzag.

  However, as shown in FIG. 8, the plurality of right side heat radiation tubes 610 and the plurality of left side heat radiation tubes 710 may be integrally piped by a connecting tube 611 or the like at the outer end thereof. In such a case, the central water supply member 810 may be formed, for example, as a pair that supplies cold water to half of the plurality of right side heat radiation tubes 610 and the plurality of left side heat radiation tubes 710 and collects cold water from the half. Good.

  Further, in the above embodiment, the right / left heat radiation tubes 210 and 310 and the right / left drain members 220 and 320 are arranged in a one-to-one relationship. However, the right / left heat radiation tubes 210 and 310 and the right / left drain members 220 and 320 may be arranged in a one-to-many or many-to-one relationship (not shown).

  In the above embodiment, the ceiling radiation system 1000 exemplifies that only cooling is performed by flowing cold water to the right heat radiation pipe 210 and the left heat radiation pipe 310. However, the right side heat radiation pipe 210 and the left heat radiation pipe 310 have It is also possible to perform heating by flowing hot water.

  Further, in the above embodiment, the right side drain member 220 and the left side drain member 320 are exemplified by only the aluminum material. However, diatomaceous earth can be applied to the lower surfaces of the right side drain member 220 and the left side drain member 320. It is.

  In this case, environmental hormones and the like can be adsorbed by diatomaceous earth, and the lower surfaces of the right drain member 220 and the left drain member 320 that become dead spaces can be used effectively. Furthermore, since the lower surfaces of the right drain member 220 and the left drain member 320 having good thermal conductivity can be insulated by diatomaceous earth, it is possible to prevent water droplets from condensing on the lower surfaces of the right drain member 220 and the left drain member 320.

  Further, in the above-described embodiment, the cold water is constantly flowed uniformly through the plurality of right side heat radiation tubes 210 and the plurality of left side heat radiation tubes 310. However, you may control the flow rate of the cold water which flows into the right side heat radiation pipe | tube 210 and the left side heat radiation pipe | tube 310 by controlling the output with the pump apparatus 410. In this case, the cooling strength can be adjusted appropriately and reliably and quickly with a simple structure.

  Further, in the above embodiment, the ceiling radiation system 1000 is formed by connecting one right radiating unit 200 and one left radiating unit 300 to one central piping unit 100.

  However, a plurality of central piping units 100 may be sequentially connected in the longitudinal direction, and a right side radiation unit 200 and a left side radiation unit 300 may be connected to each of them to form a ceiling radiation system (not shown).

  In this case, it is possible to cope with a long ceiling surface with a simple piping structure. Of course, by arranging the above-mentioned long ceiling radiation system in a direction perpendicular to the longitudinal direction, it is possible to cope with a large-area ceiling (not shown).

  Moreover, in the said form, it illustrated only that the right / left side drain members 220 and 320 and the central drainage member 130 were formed in the bowl shape of the upper surface opening. However, in this case, dust accumulated in the bottoms of the right / left drain members 220 and 320 and the central drainage member 130 may become a problem.

  Therefore, by installing a cleaning mechanism (not shown) that slides the cleaning member with a screw mechanism or the like inside the right / left drain members 220, 320 or the central drain member 130, the right / left drain members 220, 320 are mounted. Alternatively, dust that accumulates at the bottom of the central drainage member 130 may be eliminated.
