Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-tank connected ice heat storage equipment which can simplify a piping system and can take out ice slurry having a high IPF.

[0002]

2. Description of the Related Art Recently, it has been proposed to manufacture ice slurry by using electric power at night and use the cold heat for cooling in the daytime. However, it is a double pit built in the basement of a building. In the case of the ice heat storage utilizing, it is difficult to freely move the ice slurry between the heat storage tanks as compared with the case of the water heat storage.

Therefore, when the ice slurry is stored in the heat storage tank, as shown in FIG. 6, distribution pipes 2a, 2b, 2 are provided.
The heat storage tanks 1a, 1b, 1 by branching c and 2d
The ice slurry S was distributed to c and 1d. Further, at the time of thawing ice (during heat dissipation), after taking out low-temperature cold water or brine from the first tank (first tank) 1a, each heat storage tank 1a, 1b, 1
A method of spraying hot water B'in c and 1d has been adopted.

However, in the conventional heat storage tank, the distribution pipes 2a, 2b, 2c, 2d for distributing the heat medium such as the ice slurry S and the hot water B'and the water spray pipes 3a, 3 between the respective tanks.
Since it is necessary to provide b, 3c, 3d, etc. in each tank 1a, 1b, 1c, 1d, there is a problem that these pipes become very complicated. Further, there is a problem that the piping space and cost increase. Further, since it was difficult to transfer the ice slurry between the tanks, it was difficult to take out the ice slurry having a high IPF.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a conventional problem, and its purpose is not only to provide a pipe for distribution or water sprinkling for each tank. It is another object of the present invention to provide a multi-tank connected ice heat storage equipment which allows ice slurry to freely move between tanks and can take out ice slurry of high IPF when the ice is thawed (when heat is released).

[0006]

In order to achieve the above-mentioned object, the multi-tank type ice heat storage equipment of the present invention has a J-shaped pipe and one end with a non-return connection between many heat storage tanks filled with cold water or brine. A straight pipe having a valve or a pipe integrally formed with the J-shaped pipe and the straight pipe is connected to each other, and at the time of ice making, cold water or brine taken out from the final tank is made into an ice slurry by an ice making machine and returned to the first tank, and when the ice is thawed. It is characterized in that the ice slurry taken out from the first tank is returned to the final tank via a load.

As described above, a large number of heat storage tanks filled with cold water or brine are communicated with each other by a J-shaped pipe and a straight pipe having a check valve at one end, or a pipe formed integrally with the J-shaped pipe and the straight pipe. At the same time, during ice making, cold water or brine taken out from the final tank is made into ice slurry by an ice making machine and returned to the first tank, and at the time of defrosting, the ice slurry taken out from the first tank is returned to the final tank via a load for distribution. Not only does it not have to provide a pipe for water sprinkling for each tank,
The ice slurry can freely move between the tanks, and the ice slurry having a high IPF can be taken out when the ice is thawed (when heat is released).

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, A is an ice heat storage equipment, and the ice heat storage equipment A includes five connected heat storage tanks 1a, 1b, 1c, 1
d, 1e, each tank 1a, 1b, 1c, 1d,
The brine B is filled in 1e. Water may be used in place of brine B.

Further, as shown in FIGS. 2 and 3, a check valve 10 is provided on the partition wall 6 between the first tank 1a which is the first tank and the fifth tank 1e which is the last tank. The J-shaped tube 12 is integrally connected to the straight tube 11 provided in the above, and is communicated with each other by a bifurcated communication tube 13. Furthermore,
After the brine B taken out from the fifth tank 1e of the final tank is made into the ice slurry S by the ice making machine 4,
A pipe 2 for returning to the tank 1a and a pipe for returning the ice slurry S taken out from the first tank 1a which is the first tank to the fifth tank 1e which is the final tank as hot water B'through the load 5 side such as a heat exchanger. 3 and 3 are provided.

Next, the operation of the above ice heat storage equipment will be described. First, at the time of ice slurry distribution (during ice making), the brine B is taken out from the final tank 1e and enters the ice making machine 4,
The generated ice slurry returns to the first tank. On the other hand, when a predetermined amount of ice slurry S is stored in the first tank 1a, a bifurcated communication pipe 13 attached to the partition wall 6 between the first tank 1a and the second tank 1b.
The ice slurry S flowing in from the left end 11a of the straight pipe 11 (on the side where the check valve 10 is not provided) is discharged from the right end 11b of the straight pipe and the top end 12b of the J-shaped pipe 12 into the second tank 1b. Then, the ice slurry S is accumulated in the upper part of the second tank 1b, and the top end 12b of the J-shaped tube 12 is
Straight tube 1 as the ice resistance in
The discharge amount of the ice slurry S from the right end 11b of No. 1 increases.

When a predetermined amount of ice slurry S is stored in the second tank 1b in this manner, the ice slurry S is sent through the second bifurcated tube 13 to the third tank 1c having a low resistance. In this way, the first tank 1a to the second tank 1b, the third tank
The ice slurries S are stored in the tanks 1a, 1b, 1c, 1d, and 1e evenly by the self-balancing action, in succession with the tanks 1c.

On the other hand, when the ice slurry S is taken out (at the time of thawing)
The ice slurry S is taken out from the first tank 1a, which is the first tank, and is circulated to the fifth tank 1e, which is the final tank, via the load 5 such as the heat exchanger on the consumer side. During this time, the ice slurry S enters from the top end 12b of the J-shaped tube 12 of the bifurcated communication tube 13 provided on the partition wall 6 between the fifth tank 1e and the fourth tank 1d, and from the left end 11a of the straight tube 11 to the fourth end. It is discharged into the tank 1d. However, the return hot water B'in the tank does not enter from the right end 11b of the straight pipe 11 due to the function of the check valve 10.

In this way, the ice slurries S having a high IPE are successively transferred to the upstream tanks and the high IPE ice slurry S is the first tank 1a.
Taken from. In the above embodiment, the bifurcated communication pipe 13 in which the J-shaped pipe 12 and the straight pipe 11 shown in FIG. 4 are integrated has been described.
As shown in FIG. 5, a J-shaped tube 12 and a straight tube 11 may be separately arranged, or an inverted T-shaped tube may be adopted. The heat storage tank can be appropriately selected depending on the shape of the heat storage tank and the state of the ice slurry.

[0014]

As described above, according to the present invention, between a large number of heat storage tanks filled with cold water or brine, a J-shaped pipe and a straight pipe having a check valve at one end, or the J-shaped pipe and the straight pipe are provided. The cold water or brine taken out from the final tank is made into an ice slurry by an ice making machine and returned to the first tank during ice making, and the ice slurry taken out from the first tank is passed through the load to the final tank during defrosting. Since there is no need to provide a pipe for distribution or water sprinkling for each tank, the structure of the pipe and the entire equipment is simplified. Furthermore, as the ice slurry can move freely between each tank,
The ice slurry with high IPF can be taken out when the ice is thawed (when heat is released).
