〔Example〕

FIG. 1 schematically shows a part of the heat storage water tank of the present invention. The illustrated example shows a heat storage water tank in which a large water tank main body having a bottom surface 4 and an upper surface 5 formed of concrete slabs is divided into a number of small water tanks by a partition wall 6 extending from the bottom surface 4 to the upper surface 5. In the actual building, the height of the partition wall 6 varies depending on the height of the foundation and the shape of the floor according to the specifications of the structure, and the shape and volume of each small aquarium are also different. It is different, but which partition wall 6
Also, regarding the cold water and the hot water, the flow direction is reversed so that the water flows between the small water tanks in a certain order so that the flow liquid is formed by the communication pipe and the gutter of the present invention. Install the structure.

If the hot water is designed to flow from the illustrated small water tank (a) to the small water tank (g) in order (from left to right in the figure), the small water tank (a) side is High temperature tank,
When the side of the small water tank (g) is a low temperature tank and the hot water is made to flow through the small water tanks (b) to (f) in this order in order, a lower opening is made at the lower side of the high temperature tank for each partition wall 6. Gutter 2
An upper opening gutter 1 is provided on the upper side of the cryostat. When flowing cold water, keep the positions of these gutters and reverse the flow direction to the hot water. For example, looking at the small water tanks of (c) and (d), warm water flows from the small water tank (c) into the small water tank (d), and the cold water from the small water tank (d) into the small water tank (c). Therefore, a gutter 2 with a lower opening is installed horizontally in the lower part of the side surface on the small water tank (c) side of the partition wall 6 that separates these small water tanks. A gutter 1 with an upper opening is installed horizontally in the upper part of the side surface on the small water tank (d) side. Then, the upper opening gutter 1 and the lower opening gutter 2 are connected by a plurality of communication pipes 3. The installation relationship between the gutters 1 and 2 and the communication pipe 3 is the same when installed on any partition wall that divides the small water tanks (a) to (g).

FIG. 2 is a schematic view showing the state of connection between the gutters by the plurality of communication pipes 3. In FIG. 2, the right side of the partition wall 6 is a high temperature side, and the left side is a low temperature side small water tank. Upper opening gutter 1
Is horizontally installed on the upper side surface of the partition wall 6 facing the high temperature side. In the illustrated example, one edge of a flat bottom plate 8 is horizontally fixed to an upper side surface of the partition wall 6 (an upper side surface facing the high temperature side small water tank), and a vertical flat plate 9 is attached to the other side of the bottom plate 8. Gutter 1 with upper opening by standing up on the edge of
Are formed. Then, while fixing one edge of the flat upper plate 10 to the lower side surface of the partition wall 6 (the lower side surface facing the low temperature side small water tank) on the side opposite to the gutter 1 of this upper opening, A vertically open gutter 2 is formed by hanging a vertical flat plate 11 vertically from the edge of the upper plate 10.

Between the upper opening gutter 1 and the lower opening gutter 2, a plurality of communication pipes 3 penetrating the partition wall form a liquid communication passage. In this case, the bottom plate 8 of the gutter 1 is provided with The upper ends of the communication pipes 3 are penetrated at a predetermined distance from each other to open the pipe openings of the communication pipes 3 into the gutter 1, and the other ends (lower ends) of the communication pipes 3
If is opened from the side of the partition wall 6 into the gutter 2 having a lower opening, the installation is easy and the stability is good. That is, a horizontal pipe 13 having one end opened inside the gutter 2 having a lower opening is installed through the partition wall 6, and from the other end of the horizontal pipe 13 (the end located on the opposite side of the gutter 2). The pipe 14 may be raised, and the upper end of the rise pipe 14 may be inserted into the opening 12 of the bottom plate 8 of the gutter 1.

[Action effect]

According to the heat storage water tank of the present invention, the hot water flows from the lower opening gutter 2 under the small water tank to the adjacent upper opening gutter 1 of the small water tank through the plurality of communication pipes 3, and the vertical plate 9 of this gutter 1 The upper edge acts as a weir and flows into the upper part of the small water tank. That is, in any small water tank, hot water flows in from the top and at the same time flows out from the bottom, forming a piston pushing flow. When the cold water is supplied in the opposite direction to the hot water, the cold water flows from the gutter 1 at the upper opening of the small water tank to the adjacent gutter 2 at the lower opening through the multiple communication pipes 3 and the vertical direction of the gutter 2 The lower edge of the plate 11 flows into the lower part of the small water tank as a weir. That is, in any small water tank, cold water flows in from the bottom and at the same time flows out from the top, forming a piston pushing flow.

When the heat storage water tank of the present invention is divided into small water tanks,
Even if the volume of each aquarium and the height of the partition wall are mixed due to the interaction with the building, the upper opening gutter 1 and the lower opening gutter 2
The upper opening (the opening between the upper edge of the vertical plate 9 of the gutter 1 and the liquid surface) and the lower opening (the drooping plate 11 of the gutter 2) that can ideally form the piston pushing flow by adjusting the height of The opening between the floor and the floor surface 4) can be easily created.

In addition, in both the upper opening gutter 1 and the lower opening gutter 2, the water that flows in from each communication pipe 3 once joins in the gutter and then flows out horizontally into the small water tank. It is possible to avoid the occurrence of a mixed flow in which the flow velocity of the water flow flowing into the small water tank differs from place to place as in the case of the pipe system, and it is possible to form a preferable uniform extrusion flow.
