  A typical air conditioning system for air conditioning in a building is one that uses an air conditioner such as a room air conditioner. Recently, a heat medium is circulated and supplied to a radiator (radiant panel) placed in the building, An air conditioning system that heats or cools a building with hot air or cold air radiated from a radiation panel has been proposed (see, for example, Patent Documents 1 and 2).

  In the “concealed concealed heating / cooling system” described in Patent Document 1, a heating / cooling circulation type all-plastic resin is placed in a space in which the upper and lower portions of a building wall partition are closed by an upper receiving member and a lower receiving member, respectively. A heat sink (radiant panel) made of steel is suspended and a drain pan is placed at the bottom of the heat sink to collect condensed water generated in the heat sink during cooling operation and discharge it to a predetermined drainage path. .

  The radiator is formed by integrating a first heat radiating panel and a second heat radiating panel in which vertical pipe groups are connected in parallel between upper and lower main pipes in a multilayer form, and a supply pipe is connected to an upper main pipe of one of the heat radiating panels. The return pipe is connected to the upper main pipe of the other heat radiation panel.

  In the conventional radiator (radiant panel) type air conditioning system described in Patent Document 1, in order to cope with the thermal expansion / contraction of the radiant panel during heating / cooling operation, the radiant panel is the upper receiving material of the building. The drain pan (water receiving container) is fixed on the lower receiving material.

  For this reason, the relative positional relationship between the lower part of the radiation panel and the drain pan may change due to thermal expansion / contraction of the radiation panel. In particular, during the cooling operation, the radiation panel contracts and the distance between the lower portion of the radiation panel and the drain pan increases, so that the condensed water generated in the radiation panel may not reliably fall into the drain pan.

  In addition, the drain pan is fixed to the lower receiving material, and since the drain pipe and drainage pipe are routed through the lower receiving material from the drain pan, the position of the radiation panel after construction (after installing the radiation panel) It is difficult to move the drain pan accompanying the change.

The lower side of the radiant cooling / heating panel is held in an upright state by the condensation receiver. Therefore, in order to support the weight of the radiant cooling and heating panel, the dew condensation receiver has a large number of parts and must have a sturdy and complicated structure. Moreover, when employ | adopting as a heat radiation cooling / heating panel made from a synthetic resin, when a radiation cooling / heating panel expands / contracts with air conditioning operation, there exists a possibility that the process of condensed water may be obstructed. Furthermore, when the position of the radiant cooling / heating panel needs to be changed after construction (after the radiant cooling / heating panel is installed), it is difficult to move the dew condensation receiver along with the movement of the radiant cooling / heating panel.

  The problem to be solved by the present invention is that it is possible to prevent the dew condensation from splashing on the radiation panel of the thermal radiation type air conditioning system, and the movement of the radiation panel after the construction is easy to move in accordance with the position change of the radiation panel. It is to provide a condensed water drainage structure.

  With such a configuration, the radiant panel and the drain pan can be integrated by attaching the water receiving container to the radiant panel via the locking means, so that the radiant panel can be used during heating and cooling operations. Even in the case where the expansion / contraction expands, it becomes possible to keep the distance between the radiation panel and the drain pan substantially constant, and in particular, it is possible to prevent the condensation water from scattering during the cooling operation. Further, since the drain pan is attached to the radiant panel via the locking means, it is easy to move along with the position change of the radiant panel after construction. Furthermore, since the water receiving container of the drain pan has a bowl shape, it is possible to reliably receive the condensed water that has dropped from the radiation panel toward the drain pan and guide it to the drain outlet.

  In the following, drain pans 100, 200, 300, 400, 500, 600 constituting the condensed water drainage structure (hereinafter, abbreviated as “drainage structure”) of the radiation panel for air conditioning according to the embodiment of the present invention based on the drawings. , 700 and the like will be described.

  As shown in FIGS. 1-5, the drain pan 100 which comprises the drainage structure which is embodiment of this invention is the dew condensation water which arises in the fence-shaped radiation panel 80 formed with the synthetic resin material to the water receiving container 10. As shown in FIG. It is a member used by being attached to the radiation panel 80 in order to collect and discharge to a predetermined drainage path. Here, as shown in FIGS. 4 and 5, the radiation panel 80 includes a plurality of vertical pipes 81 arranged in the vertical direction, and horizontal pipes (in which the upper ends and the lower ends of the vertical pipes 81 communicate with each other in the horizontal direction ( A fence-like first panel 80a and a second panel 80b having a tubular upper header member 82 and a lower header member 83) are arranged in parallel.

  A supply pipe 84 for introducing a temperature-controlled heat medium supplied from a heat source device (not shown) such as a heat pump into the radiation panel 80 is provided at the right end portion of the upper header member 82 of the first panel 80a. A discharge pipe 85 for discharging the heat medium from the radiation panel 80 is connected to the right end portion of the upper header member 82 of the second panel 80b.

  The heat medium introduced from the supply pipe 84 circulates inside the plurality of vertical pipes 81 of the first panel 80a and the second panel 80b, and in this process, warm air or cold air is discharged from the surface of the vertical pipe 81 to thereby enter the building. After the air conditioning is performed, the air is discharged from the discharge pipe 85.

  As shown in FIGS. 1 to 4, the drain pan 100 is collected in the water receiving container 10 having the opening 11 for collecting the condensed water generated on the surface of the radiation panel 80 during the cooling operation, and the water receiving container 10. A drain port 13 provided at the bottom 12 of the water receiving container 10 for discharging the water to the drainage path, and two provided on the opening 11 side of the water receiving container 10 for attaching the water receiving container 10 to the radiation panel 80. Two locking members 14.

  The water receiving container 10 as a whole is a bowl-shaped member having a V-shaped vertical cross section, and both end portions thereof are closed by flat side walls 15. As shown in FIG. 7, the width W1 of the upper edge portion 10a of the opening 11 of the water receiving container 10 is larger than the arrangement width W2 of the two lower header members 83 of the radiation panel 80, and the upper edge portion 10a is Smoothing processing is performed. The upper edge 15 a of the side wall 15 is set lower than the upper edge 10 a of the opening 11. The distance L between the two side walls 15 is greater than the length of the lower header member 83.

  The two locking members 14 are provided upright on a portion of the opening 11 of the water receiving container 10 near the side wall 15. The locking member 14 is a flat plate member whose overall shape is a C-shape, and is capable of simultaneously holding the outer periphery of the two horizontal pipes (two lower header members 83 in parallel) of the radiation panel 80. It has the shape engaging part 14a.

  The drain pan 100 is formed by cutting a flat plate made of foamed polypropylene into a predetermined size, bending it to form a bowl shape having a V-shaped cross section, and forming triangular shapes made of the same material at both ends thereof. Can be formed by adhering two locking members 14 made of the same material to the upper edge portion 10a side. The drain pan 100 made of foamed polypropylene has good heat insulation and is lightweight, but is not limited to this, so it can be manufactured using other synthetic resin materials, metal materials, and the like. In addition to the method, an integral molding method can also be adopted.

  As shown in FIGS. 6 to 8, the drain pan 100 holds the two lower header members 83 of the radiation panel 80 with the bay-shaped engagement portions 14 a of the two locking members 14, thereby Removably attached to the bottom. In the water receiving container 10 of the drain pan 100 attached to the radiation panel 80, the longitudinal direction of the bowl shape is substantially parallel to the longitudinal direction of the lower header member 83 of the radiation panel 80. Since the number of the locking members 14 is not limited, it can be increased or decreased according to the size of the water receiving container 10 set according to the length of the lower header member 83.

  Although the method for attaching the drain pan 100 to the radiation panel 80 is not limited, for example, as shown in FIG. 9, the bay-like engagement portion 14 a of the locking member 14 is pulled on the lower header member 83 of the first panel 80 a of the radiation panel 80. If the lower header member 83 of the 2nd panel 80b is inserted in the bay-shaped engaging part 14a so that the water receiving container 10 may be rotated centering | focusing on the said lower header member 83 in that state, attachment will be completed. . Further, the drain pan 100 can be removed from the radiation panel 80 by performing the reverse operation to that described above.

  When the radiant panel 80 is in cooling operation, the dew condensation water generated on the outer peripheral surface of the vertical pipe 81 flows down along the longitudinal direction of the vertical pipe 81, reaches the lower header member 83, and then the outer periphery thereof. It passes along the surface, falls toward the opening 11 of the water receiving container 10 of the drain pan 100, and is collected in the water receiving container 10. The condensed water collected in the water receiving container 10 flows toward the drain port 13 and is discharged through the drain port 13 to a predetermined drain path.

  The drain pan 100 is attached to the radiant panel 80 via the locking member 14 so that the radiant panel 80 and the drain pan 100 are integrated. Therefore, even when the radiant panel 80 expands and contracts in the vertical direction during heating / cooling operation, The distance between 80 and the drain pan 100 can be kept substantially constant. Therefore, all the condensed water generated in the radiation panel 80 during the cooling operation is collected in the drain pan 100 without being scattered around and is discharged to a predetermined drainage path. Moreover, since the drain pan 100 is attached to the radiation panel 80 via the locking member 14, the movement with the position change of the radiation panel 80 after construction is also easy.

  Since the locking member 14 is provided on the opening 11 side of the water receiving container 10, it is easy to attach and detach the radiation panel 80 to the lower header member 83, and it is easy to check the attachment state. Further, the condensed water transmitted from the lower header member 83 to the locking member 14 can be reliably collected into the water receiving container 10, and functions as a guide for guiding the condensed water into the water receiving container 10. Since the locking member 14 is provided with a bay-like engagement portion 14a capable of gripping the lower header member 83, it can be attached without any processing on the radiation panel 80 side, and can be securely attached. .

  Further, since the water receiving container 10 of the drain pan 100 has a bowl shape that can be attached substantially parallel to the lower header member 83 of the radiation panel 80, it is possible to reliably collect the condensed water falling from the lower header member 83. In addition, the sense of unity when attached to the radiation panel 80 is good, and there is no sense of discomfort in appearance.

  Since the water flow path from the drain port 13 of the water receiving container 10 of the drain pan 100 to the predetermined drainage path is not limited, a method according to the construction site can be adopted. It can be set as embodiment shown.

  In the embodiment shown in FIG. 10, a water receiving device 20 having a funnel-shaped water receiving portion 20 a is disposed below the drain port 13 of the water receiving container 10 of the drain pan 100, and the lower drain port 20 b of the water receiving device 20 is The drainage channel 30 is communicated. Since it is not necessary to arrange another member between the drain port 13 and the water receiving device 20, alignment during construction is easy, and handling when the position of the drain pan 100 changes up and down is also easy.

  Moreover, since the water receiving device 20 has the funnel-shaped water receiving part 20a, it is only necessary to place the water receiving device 20 on the drainage path 30, and the drainage port 13 of the drain pan 100 and the drainage path 30 There is no need for a hose to connect. Furthermore, the position change of the drain port 13 of the drain pan 100 accompanying expansion and contraction of the radiation panel 80 during cooling and heating can be accurately handled.

  In addition, since the plan view shape of the water receiving portion 20a of the water receiving device 20 is a circle having a larger diameter than the outer diameter of the drain port 13, the lower end opening of the drain pan drain port 13 is within the circular region of the water receiving portion 20a. As long as there is a water receiving function. For this reason, in addition to easy alignment with the drain outlet 13 of the drain pan 100 during construction, the condensed water collected in the water receiving container 10 can be discharged to the drainage path 30 without leaking.

  In the embodiment shown in FIG. 11, a bellows-like drain pipe 21 is connected to the drain port 13 of the water receiving container 10 of the drain pan 100, and the lower end portion of the drain pipe 21 is connected to the drain path 30. Since the bellows-like drain pipe 21 has stretchability and flexibility, it is easy to align the drain port 13 and the drain passage 30 at the time of construction.

  In the embodiment shown in FIG. 12, a flexible drain pipe 22 is connected to the drain port 13 of the water receiving container 10 of the drain pan 100, and the lower end portion of the drain pipe 22 communicates with the drain path 30. Since the drain pipe 22 has flexibility and can be bent, it is easy to align the drain port 13 and the drain path 30 during construction.

  In the embodiment shown in FIG. 13, the drain pipe 23 is connected to the drain port 13 of the water receiving container 10 of the drain pan 100, and the lower end portion of the drain pipe 23 is communicated with the drain path 30. Since the drainage pipe 23 has a nested structure composed of a plurality of cylindrical bodies 23a, 23b, and 23c having different outer diameters and can be extended and contracted on the same axis, the drainage port 13 and the drainage path 30 can be aligned at the time of construction. Easy.

  Next, based on FIG. 14, FIG. 15, the drainage structure which is other embodiment of this invention is demonstrated. In the drain pan 200 constituting the drainage structure of the present embodiment, the locking member 24 is provided in the same manner as the locking member 14 of the drain pan 100 shown in FIG. 1, but the bay-like engaging portion 24 a of the locking member 24 is provided. One projecting piece 24b of the two projecting pieces 24b, 24c forming the shape is projected toward the other projecting piece 24c.

  Further, the radiation panel 70 to which the drain pan 200 is attached is a vertical pipe in which the first panel 80a and the second panel 80b forming the radiation panel 200 are adjacent to each other in the longitudinal direction of the horizontal pipe (upper header member 82, lower header member 83). The structure is displaced from each other by the same distance as the arrangement interval 81.

  When the drain pan 200 is attached to the lower header member 83 of the radiation panel 70, as shown in FIGS. 14 and 15, one protruding piece 24b of the locking member 24 is interposed between the vertical pipes 81 of the first panel 80a. The other projecting piece 24c is in a state of being located on the back side of the vertical pipe 81 of the second panel 80b (the side opposite to the first panel 80a). Accordingly, the protruding piece 24b of the locking member 24 is sandwiched between the adjacent vertical pipes 81 and functions as a stopper portion, so that the drain pan 200 extends in the longitudinal direction of the lower header member 83 of the radiation panel 70. Can be prevented from moving along.

  Although the method for attaching the drain pan 200 to the radiation panel 70 is not limited, for example, as in the attachment method shown in FIG. 9, one protrusion piece 24 b of the locking member 24 is attached to the lower header member 83 of the first panel 80 a of the radiation panel 70. In this state, the water receiving container 10 is rotated around the lower header member 83, and the other projecting piece 24c is hooked on the lower header member 83 of the second panel 80b. When the member 83 is fitted into the bay-like engagement portion 24a, the attachment is completed. Further, the drain pan 200 can be removed from the radiation panel 70 by performing the reverse operation to that described above. Since the structure and functions of other parts are the same as those of the drain pan 100, the same reference numerals as those in FIGS.

  Next, based on FIGS. 16-18, the drain pan 300 which comprises the drainage structure which is other embodiment of this invention is demonstrated. In the drain pan 300, the interval between the two projecting pieces 34b, 34c forming the bay-like engaging portion 34a of the locking member 34 is set wider than that of the locking member 14 of the drain pan 100 shown in FIG. . Further, an upright portion 10 x is provided on the upper edge portion 10 a of the water receiving container 10.

  Accordingly, as shown in FIGS. 17 and 18, for the three lower header members 83 of the radiation panel 60 having three fence-like panels (first panel 80a, second panel 80b, and third panel 80c), It can be suitably attached. Since the structure and functions of other parts are the same as those of the drain pan 100, the same reference numerals as those in FIGS.

  Next, based on FIG. 19, FIG. 20, the drain pan 400 which comprises the drainage structure which is other embodiment of this invention is demonstrated. The drain pan 400 has substantially the same structure as the drain pan 100 shown in FIG. 1, but can be attached to the radiation panel 50 having a slightly different structure from the radiation panel 80 shown in FIG. 4.

  The radiation panel 50 includes a plurality of horizontal pipes 51 arranged in parallel in the horizontal direction and vertical headers 52 (longitudinal pipes 52) having a diameter larger than that of the horizontal pipes 51. And two fence-like panels (the first panel 50a and the second panel 50b) are arranged in parallel. The locking member 44 of the drain pan 400 has a bay-shaped engaging portion (not shown) that detachably holds the two horizontal pipes 51 positioned at the lowermost part of the radiation panel 50.

  Next, based on FIG. 21, the drainage structure which is other embodiment of this invention is demonstrated. The drain pan 500 constituting the drainage structure of the present embodiment is substantially the same as the drain pan 400 shown in FIGS. 19 and 20, but in order to grip the horizontal pipe 41 of the radiation panel 40 having a structure different from that of the radiation panel 50, The positions of bay-shaped engaging portions (not shown) provided in the two locking members 54a and 54b are different from each other. Specifically, the position of the bay-shaped engagement portion of the left locking member 54a in FIG. 21 is higher than the position of the bay-shaped engagement portion of the right locking member 54b (separated above the water receiving member 10). Is set).

  The radiation panel 40 includes a plurality of horizontal pipes 41, and two fence-like panels arranged in parallel, each having a vertical header 42 (longitudinal pipe 42) having a diameter larger than that of the horizontal pipe 41 and communicating with the left and right ends thereof. The plurality of horizontal pipes 41 are inclined and arranged so as to form a downward slope, and the two vertical headers 42 are arranged in the vertical direction.

  As described above, since the position of the bay-shaped engaging portion of the locking member 54a is set higher than the position of the bay-shaped engaging portion of the locking member 54b, the horizontal pipe positioned at the lowermost portion of the radiation panel 40. 41, when the drain pan 500 is attached via the two locking members 54a and 54b, the water receiving container 10 of the drain pan 500 is held so that its longitudinal direction is substantially horizontal. Note that “maintained so as to be in a substantially horizontal state” is not limited to a complete horizontal state, but an inclined state in which the drain outlet 13 is slightly lowered (for example, an inclination of about 1 degree with respect to the horizontal). State).

  In the radiation panel 40 shown in FIG. 21, since the plurality of horizontal pipes 41 are inclined downwardly to the right, the dew condensation water generated in the radiation panel 40 is guided in the inclination direction (right side in FIG. 21), and the drain pan 500.

  Therefore, even if the condensed water generated in the radiation panel 40 falls into the water receiving container 10 of the drain pan 500 intensively from the lower side of the horizontal pipe 41, the drain port 13 of the water receiving container 10 in the horizontal state. It can be surely drained from.

  Next, based on FIGS. 22-24, the drainage structure which is other embodiment of this invention is demonstrated. A drain pan 600 constituting the drainage structure of the present embodiment has a locking member 64 having a shape different from that of the locking member 14 of the drain pan 100 shown in FIG. Two locking members 64 are provided. Other structures and functions are the same as those of the drain pan 100.

  As shown in FIG. 23, the drain pan 600 has a structure in which the left end portion 83a and the right end portion 83b of the lower header member 83 protrude outward from the vertical pipe 81a positioned at the left end and the vertical pipe 81b positioned at the right end, respectively. Suitable for mounting on panel 45.

  When the drain pan 600 is attached to the radiation panel 45, as shown in FIG. 23A, the drain pan 600 is inclined to the right and the drain pan 600 is moved to the right side in the drawing, thereby The hole engaging portion 64a is moved toward the left end portion 83a of the lower header member 83, and the left end portion 83a of the lower header member 83 is inserted into the hole engaging portion 64a of the left locking member 64.

  Next, as shown in FIG. 23B, the drain pan 600 is set in a horizontal posture, and the drain pan 600 is moved to the left side in the drawing, so that the hole-like engaging portion 64a of the right locking member 64 is moved to the lower header member 83. When the right end portion 83b of the lower header member 83 is inserted into the hole-shaped engaging portion 64a of the right locking member 64 as shown in FIG. 23 (c), the radiation panel 45 is moved. The installation of the drain pan 600 is completed.

  As shown in FIG. 24, the drain pan 600 after being attached to the radiation panel 45 is provided with two lower header members 83 in a hole-like engaging portion 64 a provided in the locking member 64 without a notch. Is held in a state of being inserted, the holding force is high, and it can be stably held for a long time after construction.

  Next, a drain pan 700 constituting a drainage structure according to another embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 25 to 27, the drain pan 700 includes a water receiving container 10 </ b> X having a shape different from that of the water receiving container 10 of the drain pan 100 shown in FIG. 1. That is, the cross-sectional shape of the water receiving container 10 of the drain pan 100 shown in FIG. 1 is V-shaped, whereas the cross-sectional shape of the water receiving container 10X of the drain pan 700 is an inverted trapezoid. Yes.
