Description

[Detailed explanation of the invention] This invention consists of placing heat storage units filled with heat storage material under the floor.
DESCRIPTION OF THE PREFERRED EMBODIMENTS An underfloor heat storage device that can be easily formed based on interconnection, can improve construction efficiency, and can effectively air-condition a room will be described below with reference to the drawings.

1 and 2, the underfloor heat storage device 1 of the present invention has heat storage units 2 arranged side by side and connected under the floor F, and as shown in FIG.
and filling the inside with heat storage material 5,
It is formed by arranging the pipe material 6 across the heat storage tank 3.

The heat storage tank 3 has a rectangular parallelepiped shape with an open top, and on its upper edge,
A flange 9 facing outward and in contact with the upper surface of the support wall 7 in the form of a cloth foundation is provided around the circumference, while the above-mentioned flange 9 is provided at approximately the center of the rising wall 10 located on both sides in the longitudinal direction of the heat storage tank 3 and near its upper edge. An insertion hole 11 for inserting the tubular material 6 is formed, and a small hole 12 for air venting is appropriately formed around the insertion hole 11.

Note that 13 is a protrusion for a pedestal provided on the lower surface of the heat storage tank 3.

The heat storage tank 3 is made lightweight using plastics such as F, R, P, steel plates, aluminum plates, etc., and its dimensions are determined in this embodiment in consideration of transportation convenience, efficiency of construction, etc. The vertical length is approximately 2 m, and the width is approximately 1 ml.

Further, as the heat insulating material 4, synthetic resin foams such as expanded polystyrene, expanded polyethylene, expanded polystyrene, expanded polyurethane, glass wool, wood wool cement, etc. can be suitably employed.

The pipe material 6 is formed using a vinyl chloride pipe or a steel pipe, and is inserted through the insertion hole 11 and placed across the heat storage tank 3, and one end of the pipe material 6 is flush with the rising wall lea of -. The other end of the opposing rising wall 10b is formed with a protrusion 16 that protrudes outward by about twice the width of the flange 9, and is connected to the tip of the protrusion 16 through a step 17. 19 are connected to each other, and a packing material 20 such as neoprene rubber is fitted into the stepped portion 17.

In addition, a large number of blow-off holes 21 are arranged in parallel on the lower surface of the tube material 6 within the heat storage tank 3.

As the heat storage material 5, stone materials such as gravel and pumice, which have excellent heat storage ability and are inexpensive, can be suitably used, and are filled to the extent that they reach the lower surface of the pipe material 6.

Therefore, the heat storage unit 2 formed in this way is
2, between the adjacent supporting walls 7, which are arranged in parallel in advance under the floor F at an interval equal to the width of the heat storage tank 3,
The heat storage unit 2 of - is placed side by side with the protrusions 16 of the tubes 6 facing in the same direction and the collars 9 in contact with the upper surface of the support wall 7.
The connection 19 at the other end of the tube member 6 disposed at a is connected to the collar portion 9°9 at one end a of the tube member 6 of another adjacent heat storage unit 2b.
By fitting until the two contact each other, the above-mentioned protrusion 1
Due to the relationship between the lengths of the tubes 6, the two tubes 6, 6 can be connected while being kept airtight by the packing material 20, and the respective terminal ends 22 of the tubular shapes sequentially connected in this way are sealed,
The starting end 23 is connected through a communication pipe 25, and the open end is connected to an air heating source 26, which is a solar heat collector installed on the roof surface.
By interposing and connecting a blower fan F to the outlet of the heat storage unit 2, and by laying a floor plate 29 on the upper surface of the flange 9 forming the joist, each heat storage unit 2... is substantially sealed by the floor plate 29. The underfloor heat storage device 1 of the present invention is formed in which the heat storage units 2 are connected to each other.

However, for example, when the blower fan F is operated in winter, the air heated by the air heating source 26 is blown out from the blow-off hole 21 toward the heat storage material 5 with force because the terminal end 22 is sealed, and the heat storage material 5 is heated. The material 5 is heated by contact with the air and stores the heat collected by the air heating source 26.

Therefore, even after sunset, the floorboard 29 is heated by the release of the heat stored in the heat storage material 5 during the day, heating the room.

Note that the air inside the heat storage unit 2 that has been deprived of heat flows through the small holes 1.
2 is released under the floor.

Also, since the air heating source 26 can be used as an air cooler at night in the summer, the heat storage material 5
It is also possible to store cold energy and cool the room.

As shown above, the underfloor heat storage device of the present invention has a structure in which pre-unitized heat storage units are placed side by side and connected under the floor.As a result, it is possible to reduce the number of on-site construction steps and improve the efficiency of construction, and each heat storage unit The amount of heat storage material filled into
Since the amount of heated air distributed can be made equal, variations in quality can be reduced.

In addition, since the room can be efficiently heated and cooled by releasing the warm or cold heat stored in the heat storage material, it is possible to save a large amount of power and is easy to maintain, compared to devices that use heating and cooling machines such as heat pumps. It has a large economic effect.

In addition, when the tube material is embedded in the heat storage material in the heat storage unit, the heat storage material can be heated from inside as the air blown out from the blowout hole rises, and the heat storage material can also be heated by heat conduction from the tube material. Because it can heat the material, it increases heat storage efficiency.

Further, when the upper surface of the flange is used as a joist as shown in the embodiment, the stored warm heat can be efficiently dissipated into the room through the floor surface.

When placing heat storage units under the floor, the height can be adjusted by interposing blocks between them and the subfloor surface, and the attic and upper part of the room, where heated air tends to accumulate, can be used as an air heating source. It can also be used.
