  Conventionally, in a housing heat storage air-conditioning system that stores heat in concrete such as floor slabs of buildings and performs indoor cooling and heating, as disclosed in Patent Documents 1 and 2, as a method of storing heat in a building housing, concrete There was a frame heat storage structure in which a hot water pipe was disposed in the slab, and heat was stored in the concrete slab through the hot water pipe. This hot water pipe is fixed to a reinforcing material such as a reinforcing bar.

  As another frame heat storage method, as disclosed in Patent Document 3, a hollow portion is formed as an air-conditioned air path in a concrete floor frame, and air for air conditioning is circulated in the hollow portion to store hot or cold heat. Air conditioning systems used for cooling and heating have also been proposed. The heat storage in this case is performed at night using night electricity.

  However, as in Patent Documents 1 and 2 of the prior art, when a hot water pipe is embedded in concrete, there is a problem that maintenance of piping cannot be performed and repair or the like cannot be easily performed. In addition, the concrete has to be poured after the hot water pipe is installed, so that the construction is troublesome and the hot water pipe may be deformed or crushed during the construction.

  In addition, in the case of the frame heat storage method disclosed in Patent Documents 3 to 5, the air for air conditioning is passed through the space in the frame to exchange heat with the frame concrete, but the air conditioner is operated at night. Therefore, the air for air conditioning is caused to flow through the hollow portion of the housing, so that the heat efficiency is poor and the operation cost is increased. Therefore, the energy consumption during operation is large, which is contrary to the social requirement of reducing CO2 emissions.

  Further, Patent Document 6 also operates the air conditioner at night as in Patent Documents 3 to 5, and as disclosed in Patent Document 6, a metal rod is projected into the air passage for air conditioning so that the frame concrete When the heat exchange is performed between the air and the air for air conditioning, the contact area between the metal rod and the air for air conditioning is small, the heat exchange efficiency between the air and the metal rod is not good, and sufficient heat efficiency cannot be obtained. In addition, a metal rod is an obstacle during maintenance and the like.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a first embodiment of the present invention. A housing heat storage structure 10 of this embodiment includes a plate-like radiation panel 12 made of metal such as an iron plate, and a surface on the back side of the radiation panel 12. A holding member 14 made of metal such as an aluminum extruded shape member fixed to the housing is provided. The radiation panel 12 is formed in a rectangular plate shape, four side edge portions 12a are erected, and a locking edge 12b of the side edge portion 12a is folded back inward. The holding member 14 holds a heat exchange pipe 16 described later, and is a long member that holds the heat exchange pipe 16 linearly. Further, if sound absorption is necessary as a function of the radiation panel 12, sound absorption holes may be formed in the radiation panel 12.

  As shown in the figure, the holding member 14 is provided with a heat equalizing plate 18 that is a plate that is superimposed on the back surface 12 c of the radiation panel 12 and a holding portion 19 that is provided at the center of the heat equalizing plate 18 and holds the heat exchange pipe 16. It is formed in the shape. The holding portion 19 is composed of a pair of semicircular curved portions 19a that are erected from the surface of the soaking plate 18 and open upward. The inner diameter of the holding part 19 by the curved part 19a is slightly smaller than the outer diameter of the heat exchange pipe 16 at normal temperature, and is formed so that the inner peripheral surface of the curved part 19a is in close contact with the outer peripheral surface of the heat exchange pipe 16, The side surface of the heat exchange pipe 16 is elastically clamped from both sides. The opening width between the pair of curved portions 19a is slightly narrower than the inner diameter of the holding portion 19, and the heat exchange pipe 16 is elastically deformed so as to be fitted between the curved portions 19a. The back surface 12c of the radiation panel 12 to which the holding member 14 is attached is subjected to a primer treatment for ensuring adhesion, and the back surface 12c is coated with a soaking plate of the holding member 16 with, for example, a thermoplastic resin hot melt adhesive. The back surface of 18 is bonded.

  The heat exchange pipe 16 is, for example, a gas barrier tube having a three-layer structure, the first layer located on the inner peripheral surface is polyurethane, and the second layer outside thereof is an ethylene-vinyl alcohol copolymer (hereinafter referred to as EVOH). And the third layer located on the outer peripheral surface outside thereof 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.

  A heat exchange member 22, which is a heat conductor made of a metal plate, is directly fixed to the surface of the frame concrete 20 constituting the frame on the ceiling side of the building by screws 24. The heat exchange member 22 includes a fixing portion 22a that is in direct contact with the frame concrete 20 and a locking step portion 22b that the locking edge 12b of the radiation panel 12 is locked. The locking edge 12b of the radiant panel 12 and the locking step 22b of the heat exchange member 22 are formed in a contact area where they are in contact with each other and heat conduction is performed satisfactorily. Thus, the radiation panel 12 is provided so as to be securely attached to the ceiling.

  Next, the heat storage effect of the housing heat storage structure 10 of this embodiment will be described. For example, when nighttime electricity is used to store heat and heat in the building concrete 20 on the ceiling of the building during the night, a heat exchange medium such as cold water or hot water is used as a heat exchange pipe during the night heat storage time. Run to 16. The heat energy of the heat exchange medium is transmitted to the holding portion 19 of the holding member 14 through the thickness of the heat exchange pipe 16, and is transmitted to the radiation panel 12 through the heat equalizing plate 18. Since the holding member 14 and the radiation panel 12 are made of metal and have good heat conduction, heat exchange with the heat exchange pipe 16 is performed well. The cold and warm heat transmitted to the radiation panel 12 is stored in the concrete frame 20 by radiation. Furthermore, the cold and warm temperature transmitted to the radiation panel 12 are transmitted from the side edge 12a to the locking edge 12b, and are thermally conducted from the locking edge 12b to the locking step 22b of the heat exchange member 22, Heat is transferred to the frame concrete 20 through the fixing portion 22a of the heat exchange member 22 and stored. Moreover, cold heat and heat are transmitted to the concrete frame 20 by radiation from the locking edge 12 b of the radiation panel 12. Thereby, the cold and warm heat from the heat exchange pipe 16 are stored in the concrete 20 which comprises the ceiling part of a building frame. Note that the heat and heat transmitted to the radiant panel 12 are stored not only in the ceiling concrete 20 but also in the entire building concrete, and also in indoor office equipment and the like.

  Next, at the time of indoor cooling during the daytime, the cooling effect by heat absorption from the frame concrete 20 is obtained by the cold stored in the frame concrete 20. Furthermore, if necessary, a heat exchange medium such as cold water can be passed through the heat exchange pipe 16 to absorb heat from the indoor side surface of the radiation panel 12. Thereby, the inside of a building can be controlled to desired temperature.

  Further, when heating is necessary, the nighttime power is similarly used, and heat is stored in the frame concrete 20 on the ceiling side of the building and used for air conditioning during the nighttime. The heat storage is performed by flowing a heat exchange medium such as hot water through the heat exchange pipe 16, and the heat is stored in the frame concrete 20 in the same manner as described above.

  In addition, air-conditioning is performed so that cold concrete is stored in the frame concrete 20 at night and radiant cooling is performed during the day, while a heat exchange medium such as hot water is passed through the heat exchange pipe 16 when necessary to raise the room temperature. It is also possible to perform. On the other hand, when it is necessary to lower the room temperature by operating lighting or electronic equipment while storing heat at night and radiant heating during the day, a heat exchange medium such as cold water is passed through the heat exchange pipe 16. It is also possible to perform air conditioning so as to lower the room temperature.

  According to the frame heat storage structure 10 of this embodiment, it is possible to efficiently store heat in the building frame at low cost by using nighttime power, and it is possible to reduce the size of the air conditioner. Furthermore, by efficiently storing heat in the housing at midnight, it is possible to reduce operating costs and CO2 emissions. Further, by using water as a heat exchange medium, it is possible to reduce the conveyance power as compared with air, and fine temperature setting is possible. In addition, the frame heat storage structure 10 can be attached not only to a newly built building but also to an existing building, and is easy to construct. Here, the heat storage effect of the frame heat storage structure 10 is higher when the building has an outer heat insulating structure.

  In addition, in the said embodiment, the structure where the level | step difference of the latching step part 22b of the heat exchange member 22 is taken large, and the edge 12b for latching of the radiation panel 12 is attached apart from the frame concrete 20 may be sufficient. Thereby, attachment of the radiation panel 12 becomes easy.

  Furthermore, since the cold or warm heat transmitted to the radiation panel 12 is stored in the concrete frame 20 by radiation and convection, the heat exchange member 22 is not necessarily a necessary member. For this reason, as shown in FIG. 3, the heat exchange member 22 may be slightly separated from the concrete frame 20 and fixed with screws 24. Furthermore, the heat exchange member 22 may be omitted, and anchor bolts (not shown) may be driven into the concrete body 20, for example, and the suspension bolts (not shown) may be suspended from the anchor bolts to fix the locking edge 12 b of the radiation panel 12. Thereby, the heat exchange member 22 can be attached irrespective of the surface property of the concrete frame 20. Also in this case, the cold heat of the heat exchange pipe 16 absorbs radiant heat and the like from the concrete frame 20 by the holding member 14 and the radiant panel 12 through the heat exchange pipe 16. Further, when warm heat is supplied to the heat exchange pipe 16, heat storage on the concrete frame 20 is performed by radiant heat from the heat exchange pipe 16.

The locking edge 34b is further bent at its edge 34c parallel to the side edge 34a. In addition, as shown in FIG. 4, the shape of the edge 34b for latching can be suitably set according to a use, intensity | strength, etc.

  The engagement of the heat exchange member 32 and the radiation panel 34 is formed by engaging the side edge portion 32a of the heat exchange member 32 with the locking edge 34b of the side edge portion 34a of the radiation panel 34.
