Below, the installation method of the radiation panel unit 1 is demonstrated.
A pipe 10, a plurality of panels 11, and a plurality of pressing members 12, which are main members of the radiating panel unit 1, are prepared. The pipe 10 is wound around a drum. Further, a plurality of clip fittings 50 and a positioning jig 60 are prepared.

  Note that the jig 60 is a jig for positioning the adjacent radiating panel single unit 6. As shown in FIGS. 15 and 16, the jig 60 has a flat plate-like portion 60a extending in the left-right direction and a fitting having a substantially U-shaped cross-section that is integrally formed on the left end side of the flat plate-like portion 60a and is opened downward. The joint recess 60b and a contact portion 60c having a substantially L-shaped cross section formed integrally on the right end side of the flat plate portion 60a are configured. Here, the length L in the longitudinal direction of the flat plate-like portion 60 a is set to a predetermined length corresponding to the interval between the adjacent radiating panel single bodies 6. A specific method of using the jig 60 will be described in the following installation method of the radiation panel unit 1.

  First, the configuration of the system ceiling will be described. On the system ceiling, as shown in FIG. 3, suspension bolts 4 are suspended from the ceiling slab 3. As shown in FIG. 4, a hanger hardware 70 is attached to the suspension bolt 4, and the cross member 5 is suspended from the suspension bolt 4 via the hanger hardware 70.

  Next, the main members of the radiating panel unit 1 are assembled to the cross member in a predetermined order, the radiating panel unit 1 is assembled, and the radiating panel unit 1 is installed on the system ceiling. Specifically, it is as follows.

  (1) First, a plurality of clip fittings 50 are attached to the cross member 5 along the extending direction, and the fitting recesses 31a and 31b of the pressing member 12 are fitted into the fitting portions 50a and 50b of the clip fittings 50. The plurality of pressing members 12 are suspended in parallel on the cross member 5. In consideration of the positioning process of the subsequent pressing member 12, the attachment of the clip metal fitting 50 to the cross member 5 is temporarily fixed.

  (2) Next, the adjacent pressing member 12 is positioned using the jig 60. Specifically, as shown in FIG. 17, the fitting recess 60 b is mounted from above the left pressing member 12 of the adjacent pressing members 12. At this time, since the left side surface 60b1 of the fitting recess 60b is pushed and expanded by the standing piece 32a of the pressing member 12, the left side surface 60b1 elastically abuts against the standing piece 32a. It will be fitted snugly. And the contact part 60c of the jig | tool 60 is made to contact | abut to the standing piece 32a of the right side pressing member 12 of the adjacent pressing members 12. FIG. Thereby, the space | interval of adjacent pressing member 12 can be made into the longitudinal direction length L of the flat-plate-shaped part 60a. Therefore, by using the jig 60, the plurality of pressing members 12 are attached to the cross member 5 at a predetermined interval.

  (3) Next, the panel 11 is arranged below each pressing member 12, the pipe 10 is fitted into the pipe receiving portion 18 of the panel 11, and the straight portion 10 a of the pipe 10 exists in the pipe receiving portion 18 and is adjacent thereto. Between the pipe receiving portions 18, there is a curved portion 10b of the pipe 10, and the pipe 10 is laid so as to have a meandering shape in plan view.

(4) Next, by pushing each panel 11 toward each pressing member 12, the pair of engaging portions 19 a and 19 b of the pressing member 12 are engaged with the pair of engaged portions 20 a and 20 b of the panel 11. As a result, the pipe 10 laid by the pipe receiving portion 18 and the pipe pressing portion 30 is held and fixed.
If necessary, a plurality of anti-separation fittings 15 are attached along the longitudinal direction of the radiating panel unit 6.
Thus, the radiation panel unit 1 is assembled at the construction site and installed on the system ceiling.

(Embodiment 2)
18 is an enlarged cross-sectional view of the main part of the radiant panel unit according to Embodiment 2, and FIG. 19 is the number of panels per unit of the radiant panel unit according to Embodiment 2 and per unit of the radiant panel unit according to Embodiment 1. It is a figure for comparing and explaining the number of panels. Although the panel 11 is arranged in parallel with the floor surface in the first embodiment, the panel 11 is inclined and arranged on the floor surface in the second embodiment. In the radiating panel unit 6A according to the second embodiment, the upright piece 32a of the holding member 12A is formed longer than the upright piece 32b, and the pipe holding portion 30 corresponding to this is predetermined with respect to the floor surface. Except for being formed at an angle (for example, about 45 degrees), it is the same as the radiating panel unit 6 according to the first embodiment. The method for installing the radiant panel unit 6A on the ceiling slab 3 is the same as the method for installing the radiant panel unit 6 on the ceiling slab 3 according to the first embodiment. In addition, as the arrangement | positioning state of the panel 11 inclined diagonally, it arrange | positions so that the both ends of adjacent panels 11 may overlap a little (horizontal distance L2 overlap). As a result, the ceiling surface becomes invisible from the indoor side, so that the aesthetics can be improved.

  Further, as shown in FIG. 19 (2), the radiating panel unit 1A including the radiating panel unit 6A group having the above-described configuration is arranged as shown in FIG. 19 (1) by arranging the panels 11 on the floor surface. In addition, compared to the case where the panels 11 are arranged in parallel to the floor as in the first embodiment, the number of panels per unit installation width M (for example, 4 to 5 panels in the first embodiment) In contrast, in the second embodiment, the number of panels is 7 to 8). In other words, compared with the first embodiment, the installation panel area per unit is increased in the second embodiment. Therefore, since the radiant heat transfer area is increased, the heat radiation capability is increased.

  Furthermore, compared with the case where the gap between the panels 11 is small in the horizontal direction as in the first embodiment, the gap between the panels 11 is large in the vertical direction in the second embodiment. As a result, the capacity of the gap between the panels 11 increases, so that natural convection is likely to occur. In addition, due to the property that the airflow flows along the surface of the object (Coanda effect), the diagonally arranged panels 11 serve as guides. Natural convection can be generated along the surface in a direction toward the target space.

  Thus, in the second embodiment, both radiant heat transfer and natural convection heat transfer that determine the overall heat transfer capability of the radiant panel are improved as compared to the first embodiment.

  In the present embodiment, all the panels 11 are arranged so as to incline from the upper right to the lower left in order to mainly cool (or heat) the right side of the room, but the standing pieces 32b are formed longer than the standing pieces 32a. If the presser member 12 formed so that the pipe presser 30 is inclined about 45 degrees with respect to the floor surface (inclined from the upper left to the lower right) is used, The panel 11 can be arranged in an inclined manner from the upper left to the lower right, and the left side of the room can be mainly cooled (or heated).

(Embodiment 3)
20 is a cross-sectional view showing the overall configuration of the radiating panel unit according to Embodiment 3, and FIG. 21 is a partially enlarged view of FIG. Although the flat panel 11 is used in the first embodiment, the third embodiment uses the panel 11A having a V-shaped cross section. A specific description will be given below with reference to FIGS.

  The radiating panel unit 6B has a symmetrical shape with respect to the vertical plane including the bottom of the V-shaped panel 11A, and is composed of the panel 11A and a pair of left and right pressing members 12A and 12B. The holding members 12 </ b> A and 12 </ b> B are suspended from the cross member 5 by clip fittings 50 and 50. The method of installing the radiant panel unit 6B according to Embodiment 3 on the ceiling slab 3 is the same as the method of installing the radiant panel unit 6 according to Embodiment 1 on the ceiling slab 3.

  The radiating panel unit 1B including the radiating panel unit 6B group having the above-described configuration uses a panel 11A having a V-shaped cross section, and thus has a unit installation area as compared with the case where the flat panel 11 as in the first embodiment is used. The panel area per unit increases. Therefore, since the radiant heat transfer area is increased, the heat radiation capability is increased. In addition, since the surface capable of performing heat radiation is formed in two left and right surfaces, heat radiation can be performed over a wide area.

  Further, in the inclined surface type panel as in the present embodiment, the flow velocity of the air flowing along the panel surface is larger than in the horizontal case, and the heat transfer coefficient between the air and the inclined surface type panel surface is high. As a result, good natural convection will occur.
