Description

  The present invention relates to a cooling / heating panel that performs indoor cooling or heating by radiant heat.

  Conventionally, there has been a radiation type air conditioning panel installed on the ceiling. Such an air conditioning panel has a radiation panel made of metal or gypsum board, and a plurality of sound absorbing holes are formed through the radiation panel. A heat exchange pipe made of resin is disposed on the rear surface of the radiation panel. The air conditioning panel is installed on the ceiling, and a fluid having a desired temperature is allowed to flow through the heat exchange pipe for air conditioning.

  Resin heat exchange pipes are characterized by good workability, light weight and low cost, but when a fire breaks out, flames enter the back of the radiant panel through the sound absorption holes and ignite the heat exchange pipes. There is a risk. Even if it does not ignite, there is a risk of melting from heat and leaking from the sound absorption holes of the radiation panel. For this reason, the incombustibility certification in the Building Standard Law and the Fire Service Law could not be obtained.

In order to solve this problem, a ceiling radiant cooling / heating panel disclosed in Patent Document 1 is provided. In this ceiling radiant cooling and heating panel, a non-combustible sheet or a non-combustible plate material is interposed between a radiant panel in which sound absorbing holes are formed and a heat exchange panel. Further, as disclosed in Patent Document 2, the sound absorption holes of the radiant panel are formed in portions other than the heat exchange pipe and the metal heat equalizing plate covering the heat exchange pipe, The thing provided in the radiation panel between the boards is also proposed.

  In the case of the above conventional technology, the non-combustible sheet between the heat exchange pipe and the radiant panel uses a ceramic sheet having a high thermal conductivity, so the non-combustible sheet has a significantly higher thermal conductivity than metal. It was something that fell. Accordingly, heat cannot be reliably and efficiently transmitted as in the case of metal, and the thermal efficiency of the air conditioner becomes low.

  Moreover, when the position of the sound absorption hole of the radiant panel is provided at a position other than the mounting position of the heat exchange pipe as in Patent Document 2 and the heat exchange pipe is sandwiched between metal plates as non-combustible plate materials, the thermal efficiency is high. The construction man-hours required and the cost was likely to be high.

  The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide an air conditioning panel having a simple structure, high thermal efficiency, and high incombustibility.

The present invention provides a plate-shaped radiation panel, a plurality of sound absorbing holes penetrating the radiation panel, a metal receiver partially disposed on the back surface of the radiation panel, and a resin product held by the receiver The heat exchange pipe is provided with alternating straight portions and curved portions, and the support is a long member attached along the straight portion of the heat exchange pipe. , the cross-sectional shape of said receptacle, said the soaking plate is a flat plate body superimposed on the radiation panel, the retention portion is erected from the soaking plate that abolish engaging the heat exchange pipe upward opening A semicircular curved portion, and the heat equalizing plate reaches the curved portion continuously to the linear portion of the heat exchange pipe, and the vicinity of the end of the heat equalizing plate reaching the curved portion is the holding portion is removed, the holding unit, on both sides of side surfaces of the heat exchange pipe Is intended to et resilient manner sandwiching, the radiation panel back surface, incombustible sheet is laid on a portion other than portions where the soaking plate is provided, wherein the incombustible sheet, a ceramic sheet or a glass wool sheet, An air conditioning panel in which the edge is held by being inserted into a notch formed on the back surface of the heat equalizing plate, the back surface of the receiver is painted black, and the sound absorption holes are covered with the non-combustible sheet. is there.

  The heat exchange pipe is a gas barrier tube, a layer located on the inner peripheral surface is polyurethane, an outer layer thereof is an ethylene-vinyl alcohol copolymer (hereinafter referred to as EVOH), and an outer peripheral surface on the outer side thereof. The layer located at is polyurethane.

  Alternatively, in the heat exchange pipe, the layer located on the inner peripheral surface is nylon, the outer layer is polyurethane, the outer layer is EVOH, and the outer layer located on the outer peripheral surface is polyurethane. is there.

  The cooling / heating panel of the present invention has a simple structure and good thermal efficiency, and the metal receiver can reliably transmit the temperature of the heat exchange fluid in the heat exchange pipe to the radiation panel. In addition, a non-combustible sheet is provided in a portion other than the receiver, and even if a resin is used for the heat exchange pipe, the non-combustibility can be ensured reliably, and the soundproofing effect by the sound absorbing holes is maintained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show a first embodiment of the present invention, and a cooling and heating panel 10 of this embodiment is provided with a plate-like radiation panel 12. The radiation panel 12 is formed of a metal such as aluminum or iron, gypsum board, concrete or the like, and has a plurality of sound absorbing holes 14 formed therethrough.

  On the back surface 12a of the radiation panel 12, a heat exchange pipe 16 is provided via a receiving member 18 described later. The heat exchange pipe 16 is alternately provided with straight portions 16a that cross the width of the radiant panel 12 in one direction and curved portions 16b that are bent and bent before reaching the end of the radiant panel 12, and meander continuously. Yes.

  As shown in FIG. 5, the heat exchange pipe 16 is a gas barrier tube having a three-layer structure, the first layer 17 located on the inner peripheral surface is polyurethane, and the second layer 19 outside thereof is EVOH. The third layer 21 located on the outer peripheral surface outside is polyurethane. EVOH has a high gas barrier property and prevents oxygen in the air from being dissolved in the heat exchange fluid passing through the heat exchange pipe 16. EVOH is water-soluble, but since the inner and outer surfaces are covered with the first layer 17 and the third layer 21 made of polyurethane, it does not dissolve even when water is used as the heat exchange medium. Further, since EVOH is hard and easily cracked, the curved portion 16b is formed by bending during high temperature molding. When bending after molding, bend by heating. Since polyurethane is soft and easily deformed, it is easy to put it in a holding portion 22 of a receiving member 18 to be described later. Furthermore, since polyurethane has impact resilience, it returns to its original state after being put in the holding portion 22 described later, and is securely held in close contact with the holding portion 22, so that the thermal efficiency is improved.

  A receiver 18 that holds the straight portion 16 a of the heat exchange pipe 16 is attached to the back surface 12 a of the radiation panel 12. The receiving member 18 is made of metal such as an aluminum extruded shape member, is a long member attached along the straight portion 16a of the heat exchange pipe 16, and has a constant cross-sectional shape in the longitudinal direction. As shown in FIG. 3, the cross-sectional shape of the receiver 18 is provided with a soaking plate 20 that is a plate that is stacked on the back surface 12 a of the radiation panel 12, and a heat exchange pipe 16 is provided at the center of the soaking plate 20. A holding part 22 for holding is provided. The holding portion 22 is formed with a semicircular curved portion 22a that is erected from the heat equalizing plate 20 and opens upward. A wing portion 22b that spreads outward is integrally formed at the distal end of the curved portion 22a. Is formed. The inner peripheral surface of the bending portion 22a is formed to have an inner diameter that is in close contact with the outer peripheral surface of the heat exchange pipe 16, and the side surfaces of the heat exchange pipe 16 are elastically sandwiched from both sides. The back surface 12a of the radiation panel 1 to which the receiver 18 is attached is subjected to a primer treatment for ensuring adhesion, and is adhered to the back surface 12a with, for example, a thermoplastic resin hot melt adhesive or double-sided tape. . Further, the back surface of the receiver 18 is painted black so that it is difficult to see from the front side of the radiation panel 12 through the sound absorbing hole 14.

  Here, a method of attaching the heat exchange pipe 16 to the receptacle 18 will be described. The heat exchange pipe 16 is pressed between the pair of wing portions 22b to elastically deform the curved portion 22a and the heat exchange pipe 16, and are elastically locked between the curved portions 22a. At this time, a dedicated jig for pushing the heat exchange pipe 16 into the curved portion 22a of the support 18 may be used.

  On the back surface 12 a of the radiation panel 12, a non-combustible sheet 23 is laid on a portion other than the receiving member 18 to cover the sound absorbing hole 14. The non-combustible sheet 23 is, for example, a ceramic sheet, a glass wool sheet, or other non-combustible sheet. As shown in FIG. 3, the non-combustible sheet 23 is inserted into the notches 20 a formed on the back surfaces of both side edges of the heat equalizing plate 20 of the receiving device 18, and the edges are held.

  Next, the usage method of the panel 10 for an air conditioning will be demonstrated based on FIG. The cooling / heating panel 10 is mounted side by side on the ceiling of the room, and at this time, the back surface 12a of the radiation panel 12 is set to the attic side. Then, the end portions of the heat exchange pipe 16 are connected by a connecting member 24. One end of the heat exchange pipe 16 connected to the plurality of cooling and heating panels 10 is connected to the supply-side main pipe 26, and the other end is connected to the return-side main pipe 28. The supply side main pipe 26 and the return side main pipe 28 are connected to a heat source 30 such as a water heater.

  The heat source 30 supplies a heat exchange fluid having a desired temperature to the heat exchange pipe 16 of the air conditioning panel 10. The heat exchange fluid is, for example, water. Water of a predetermined temperature supplied from the heat source 30 to the supply-side main pipe 26 is supplied from one end of the heat exchange pipe 16, passes through the plurality of heat exchange pipes 16 connected by the connecting member 24, and passes through the other heat exchange pipe 16. It flows from the end to the return side main pipe 28 and returns to the heat source 30. In the process of water passing through the heat exchange pipe 16, heat exchange is performed with the radiation panel 12. In the heat source 30, water is adjusted again to a desired temperature and supplied to the supply-side main pipe 26.

  According to the panel 10 for air conditioning according to this embodiment, the structure is simple, the soundproofing effect by the sound absorption holes is maintained, the nonflammability is ensured, and the heat exchange can be surely performed. Since the receptacle 18 is made of a metal having high thermal conductivity, heat is exchanged between the heat exchange pipe 16 and the radiant panel 12 via the receptacle 18, and the thermal efficiency is good. When water is passed through the heat exchange pipe 16, the diameter of the heat exchange pipe 16 is slightly increased due to the temperature and pressure of the water, the heat exchange pipe 16 comes into close contact with the curved portion 22 a of the receiver 18, and the thermal efficiency is further increased. Further, since the soaking plate 20 is provided long along the heat exchange pipe 16 and is bonded to the radiation panel 12 in a wide area, the thermal efficiency is also improved from this point.

  Moreover, since the part other than the receptacle 18 of the radiation panel 12 is covered with the incombustible sheet | seat 23, the panel 10 for air conditioning improves nonflammability and prevents that the heat exchange pipe 16 is ignited at the time of a fire. . Even if an inexpensive synthetic resin is used for the heat exchange pipe 16, the incombustibility certification can be obtained.

  The heat exchange pipe 16 has a three-layer structure. The first layer 17 and the third layer 21 are made of polyurethane and are flexible and easy to process. The second layer 19 is an ethylene-vinyl alcohol copolymer (EVOH) having a high gas barrier property. It prevents the oxygen in the air from dissolving in the circulating water. Since oxygen does not dissolve in water, even if the connecting member 24 or the like is made of metal, it does not corrode and can have durability.

  Since the heat exchange pipe 16 is attached and held by the elastic force of the holding portion 22, a special locking device is unnecessary and has a simple structure. Further, the heat exchange pipe 16 can be easily attached and detached, and when the heat exchange pipe 16 is attached, the heat exchange pipe 16 can be simply operated by pressing between the wing portions 22b of the holding portion 22 and guided to the wing portion 22b of the holding portion 22. Thus, it can be easily pushed into the curved portion 22a. By being guided by the wing portion 22b, the holding portion 22 is not damaged due to excessive force, which is safe.

  In addition to the three-layer structure, the heat exchange pipe 16 may have a four-layer structure as shown in FIG. As for the gas barrier tube of the heat exchange pipe 32 shown in FIG. 6, the 1st layer 34 located in an internal peripheral surface is nylon, and the 2nd layer 36 of the outer side is polyurethane. The third layer 38 on the outer side is EVOH, and the fourth layer 40 located on the outer peripheral surface on the outer side is polyurethane. Since the nylon of the first layer 34 is resistant to water, durability of the metal connecting member 24 and the like can be improved. Further, nylon can be laminated on the outside of the gas barrier tube, or a known resin can be laminated other than nylon.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. Also in the air conditioning panel 42 of this embodiment, a receiving tool 44 that holds the straight portion 16 a of the heat exchange pipe 16 is attached to the back surface 12 a of the radiation panel 12. The receiving tool 44 is made of a metal such as an aluminum extruded profile, is a long member attached along the straight portion 16a of the heat exchange pipe 16, and has a constant cross-sectional shape in the longitudinal direction. The receiver 44 is provided with a soaking plate 46 that is a plate that is stacked on the back surface 12 a of the radiation panel 12, and the holding unit 22 is provided at the center of the soaking plate 46.

  The holding | maintenance part 22 is provided only in the part in which the heat exchange pipe 16 linear part 16a is located of the soaking | uniform-heating plate 46, and is holding the linear part 16a. An end 46 a in the longitudinal direction of the heat equalizing plate 46 is in contact with a curved portion 16 b that is continuous with the straight portion 16 a of the heat exchange pipe 16. The holding portion 22 is removed from the vicinity of the end portion 46a of the heat equalizing plate 46 in contact with the curved portion 16b. For this reason, the curved portion 16b is only placed on the soaking plate 46. At the central portion of the curved portion 16b, it is detached from the soaking plate 46, passes over the non-combustible sheet 23, and rests on the end portion 46a of the soaking plate 46 of the adjacent receiving tool 44 to become the straight portion 16a. Retained.

  In addition, the holding part 22 may be removed from only the side where the curved part 16b of the heat exchange pipe 16 is bent, and in this case, the same effect as described above is obtained. Further, the curved portion 16b may be connected to the holding portion 22 of the adjacent heat equalizing plate 46 so as to get over without removing the holding portion 22. In this case, the number of steps for removing the holding unit 22 can be reduced.

  The cooling / heating panel 42 of this embodiment has the same effect by the same usage as in the above embodiment. Since the soaking plate 46 is also located between the curved portion 16b of the heat exchange pipe 16 and the radiation panel 12, the area of the soaking plate 46 is increased, and the thermal efficiency is further improved.

  Next, a third embodiment of the present invention will be described with reference to FIGS. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the cooling / heating panel 50 of this embodiment, the support 18 that holds the straight portion 16 a of the heat exchange pipe 16 is attached to the back surface 12 a of the radiation panel 12.

  The heat exchange pipe 16 of this embodiment is attached to the holding portion 22 by being bent in the same direction every other piece with respect to the receiver 18 fixed to the radiation panel 12.

  The air-conditioning panel 50 of this embodiment also has the same effect by the same usage method as the above-described embodiment, and the bending direction of the heat exchange pipe 16 is constant since the bending direction of the heat exchange pipe 16 is constant. The curved portion 16b can be set more easily because the curved portion 16b is always curved in the direction.

  Similarly, as shown in FIG. 12, both ends of the heat exchange pipe 16 may be brought to both sides of the radiation panel 12. Also in this case, the same effect as the above embodiment can be obtained.
