Abstract

PURPOSE:To quickly raise the floor temperature and uniformly distribute the heat released by heat storing material throughout the floor by filling every other pipes which are in contact with each other and partitioned by a separator wall with the heat storing material, and causing said heat storing material to absorb the thermal energy from hot water across the separator wall, said hot water being supplied to the panel unit. CONSTITUTION:The hot water panel unit 21 is made with plastic material, and has multiple pipes which are in contact with each other. A pipe adjacent to a hot water supply pipe 22 and a return pipe 23 is filled with heat storing material 25. As hot water supplied from a heating device to an inlet 27 flows from the supply pipe 22 through separator walls 24 to the return pipe 23 and back to the heating device out of an outlet 28, the heat storing material 25 adjacent to the supply pipe 22 and the return pipe 23 absorbs the thermal energy from hot water across the pipe wall. Since the heat conducting area is large relative to the hot water circulation, the heat storing material 25 quickly changes its Phase from solid to liquid. Further, as the floor material 8 is in contact with the heat storing material 25 and hot water pipes 22, 23 via the panel top wall, the floor can be heated with a uniform temperature distribution.

In the figure, 1 is the panel main body, 2 is the outgoing path of hot water formed through the panel main body 1, and 3 is the returning path of hot water, the outlet of which is connected to a heating device such as a solar collector. .

FIG. 5 shows that a latent heat storage material (hereinafter referred to as heat storage material) 4, which is a plastic bag filled with salt hydrate, paraffin, etc., is embedded in a concrete floor 5 in close proximity to the panel main body 1. FIG. 6 is a sectional view showing a hot water floor heating system in which a heat insulating material 6 is provided, and FIG.

5 and 6 above, if the water is heated by the heat energy of the sun such as a solar heat collector during the day and this hot water is circulated inside the panel body 1, the heating temperature is usually 25 to 30%. Since the heat storage material 4, which changes phase from solid to liquid at ℃, is liquefied, the latent heat energy accumulated during this phase change can radiate heat energy of a predetermined heat capacity and heat the floor surface even if hot water circulation is stopped. do.

[Problem that the invention seeks to solve]

In the conventional hot water floor heating system as described above, the heat storage material 4 filled in a bag is provided between the panel body 1 that circulates hot water and the floor surface, so the heat storage material 4 is kept under external pressure. In order to protect the heat storage material 4 from damage, the heat storage material 4 is embedded in the concrete floor 5 as in the case of Fig. 5, or a strong material is used as the flooring material 8 above the heat storage material 4 as in the case of Fig. 6. Then, the flooring must be laid on top of the joists 7. Moreover, when heating is started by circulating hot water within the panel body 1 from when the heat storage material 4 is in a solid state, the heat storage material 4 receives heat energy from the bottom, as shown by the arrow in FIG. As a result, the heat storage material 4 gradually changes to a liquid phase 10, but the thickness T of the heat storage material 4
If it is relatively thick, the rate of heat conduction through the remaining solid phase 11 is slow, and it takes a long time to achieve the desired temperature rise on the floor surface. Further, there is a problem in that temperature unevenness occurs between areas where the heat storage material (4) is installed and areas where the heat storage material (4) is not installed with respect to the floor surface, causing discomfort to those in the room.

This invention was made to solve these problems, and it eliminates the need to embed the heat storage material in concrete to protect it from external pressure or use a strong flooring material, and it does not require hot water to be supplied to the pile body. The purpose of the present invention is to provide a hot water heating system that rapidly raises the floor surface temperature when started, and in which heat radiation from the heat storage material is evenly distributed over the floor surface.

[Means for solving problems]

The hot water heating device according to the present invention includes a panel body formed from a plastic material and consisting of a plurality of conduits connected via partition walls, and every other conduit is filled with a latent heat storage material and sealed. A hot water panel is installed in which the remaining pipes serve as the outbound and return routes for hot water, and a flooring material is provided in contact with the top surface of the hot water panel.

[Effect]

The heat storage material in this invention is subdivided and adjoins the hot water channel-3 through the partition wall, so when hot water starts circulating, the heat storage material rapidly changes from a solid phase to a liquid phase due to its large heat conduction area. Change. In addition, since the flooring material, the heat storage material, and the hot water channel are in contact with each other through the top wall of the panel,
Heating the floor surface with even temperature distribution.

〔Example〕

FIG. 1 is a sectional view of a hot water panel according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA in FIG.

21 is molded from a plastic material such as a polypropylene copolymer, and as shown in FIG.
The panel body 25 in which the hot water is formed is a heat storage material filled in a pipe adjacent to the outgoing path 22 and the returning path 23 of hot water, and is closed by plugs 26 at both ends of the pipe. 6
8 is a heat insulating material, and 8 is a floor material provided in contact with the upper surface of the panel body 21.

In the hot water type floor heating system according to the present invention configured as described above, as shown in FIG.
The hot water supplied to the inlet 27 flows from the outgoing path 22 through the bulkhead 24 to the incoming path 23 according to the direction of the arrow, and then flows to the incoming path 23 through the exit path 28.
Since the flow is returned to the heating device, the outgoing route 22 and the returning route 23
The heat storage material 25 adjacent to absorbs the thermal energy of the hot water through the partition wall of the pipe.

Here, as shown in FIG. 3, the above-mentioned hot water panel is installed between the flooring material 8 of the house and the heat insulating material 6 using a solar heat collector 29 as a heat source, and the circulation pump 30 is used to connect the pipe line of the panel body 21. When hot water is circulated, for example, hot water heated by solar heat during sunny days during winter warms the heat storage material 25 whose phase change temperature is 25 to 30°C through the partition wall while circulating through the pipes. The amount of heat due to the latent heat generated during this phase change is stored in the heat storage material 25 when the same phase is changed to the liquid phase.

Next, when the irradiation of solar heat ceases and the indoor temperature drops below the above phase change temperature (25 to 30°C), the heat from the heat storage material 25 is conducted indoors through the flooring 8 and the carpet 9, and the heat storage material 25 dissipates the amount of heat stored by the latent heat and changes from a liquid phase to a solid phase. In this case, since the heat storage materials 25 are distributed at even positions with respect to the eight surfaces of the floor material where heat is dissipated, heating can be performed without temperature unevenness over the entire floor surface.

In the above embodiment, an example of floor heating has been described, but the same effect as in the above embodiment can be obtained even if a hot water panel is provided in the wall to perform heating from the wall surface.

〔Effect of the invention〕

As explained above, in this invention, a heat storage material is filled in every other contiguous pipe line partitioned by a partition wall, and this heat storage material absorbs thermal energy from hot water through the partition wall. This has the effect that the phase change of the liquid phase of the heat storage material is faster than that of the solid phase, and that the floor surface can be heated with an even temperature distribution.
