DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice heat storage system.

[0002]

2. Description of the Related Art When cooling and heating by circulating cold and hot water stored in a heat storage tank to a water-side heat exchanger of a fan coil unit and a water heat source heat pump unit disposed in a building, the cooling heat during cooling is stored. In recent years, a so-called ice heat storage system for storing ice in a tank has attracted particular attention because a small-scale device can store a large amount of cold heat.

The ice stored in the heat storage tank in such an ice heat storage system is classified into an ice block and a sherbet according to the type of the ice to be generated and used. I. P. F. (The filling rate of ice) can be increased, and the heat storage efficiency can be improved.

In producing such sherbet-like ice, for example, JP-A-63-217171, JP-A-63-231157, and JP-A-1-11468.
In the technology disclosed in Japanese Patent Laid-Open Publication No. 2 (1993) -210, a method and an apparatus for continuously generating supercooled water have already been proposed. In this subcooler, for example, a heat transfer tube through which water flows is disposed in a cooling vessel, and brine of a refrigerator is circulated as a cooling medium in the cooling vessel, or the cooling vessel is evaporated by a heat pump device. The superheater is configured so as to discharge supercooled water of 0 ° C. or less from the discharge end of the heat transfer tube.

According to these known techniques, supercooled water is continuously discharged into the air from a discharge port of a heat transfer tube of a supercooler, and the discharged flow collides with a supercooling releasing means such as a collision plate to generate an impact. By applying the water, the sherbet-like ice can be continuously and efficiently generated in a slurry state with water (ice / water slurry). Since the ice heat storage system that generates and supplies this to the heat storage tank and stores it in the heat storage tank is extremely efficient, it is being widely used for air conditioning of buildings and the like.

In recent years, in consideration of an increase in demand and application to large-scale buildings, for example, an ice heat storage system having a plurality of heat storage tanks using an underground slab has been proposed and developed. The intake of water to be supplied to the subcooler is performed for each heat storage tank. The reason is, for example, when each heat storage tank is simply communicated with an appropriate communication pipe and water is taken from one of the heat storage tanks, ice adheres to the communication pipe to form an ice layer, and as a result, This is because the passage resistance of the water passing through the ice layer increases, and the water level difference between the heat storage tanks becomes excessively large, which may cause an operation failure. Therefore, conventionally, even if each heat storage tank is connected, water is often taken from each heat storage tank.

On the other hand, in order to stably generate supercooled water, it is necessary to prevent ice nuclei from being mixed into the water supplied to the supercooler. The nucleus separation device has been used, for example, in individual intake lines to perform the ice nucleus separation operation.

[0008]

However, the above-mentioned prior art has the following problems. First, if a configuration is adopted in which water is taken from individual heat storage tanks, the amount of piping on the water intake side increases with an increase in the number of heat storage tanks, and the entire system becomes complicated and bloated, including around pipes.

On the other hand, regarding an ice nucleus separation apparatus using a membrane filter, if a large-scale system using an underground pit or the like is used, clogging of the membrane due to long-time operation occurs, and management of filter replacement and the like is complicated. In addition, if an ice nucleus separation device using such a membrane filter is installed for each heat storage tank, the labor required for filter replacement is increased. Furthermore, when the membrane filter is in the tank, the filter has to be pulled out of the tank at the time of replacement, maintenance and the like of the filter, which is an extremely troublesome operation.

The present invention has been made in view of the above points, and in the above-mentioned ice heat storage system having a plurality of heat storage tanks, basically, these heat storage tanks are communicated to supply water for a heat source to a supercooler. By taking water from one place, the pipes and the system are simplified, and ice is not attached to the communicating part to suppress the difference in water level between the heat storage tanks, which hinders the operation of the system. The purpose is not to cause.

Further, according to the present invention, the function of separating ice nuclei, which has conventionally been installed in individual heat storage tanks, is integrated into one place. Further, the filter medium directly responsible for ice nucleus separation is made a new one, and maintenance of the filter medium is performed. It is another object of the present invention to easily perform various managements including the above.

According to the first aspect, a water permeable pipe having a water permeable portion is provided at the bottom of a plurality of heat storage tanks, and the water permeable tubes are connected to each other by the water permeable pipe so that the water permeable portions are located in the respective heat storage tanks. Therefore, it is not necessary to take water from each heat storage tank, and it is sufficient to take water from one of the communicating heat storage tanks.

Furthermore, since each of these heat storage tanks communicates with a water-permeable pipe having a water-permeable portion, ice blocks and coarse ice nuclei are trapped by the water-permeable portion and do not enter the inside of the water-permeable pipe. Therefore, it is possible to prevent the ice from adhering to the communicating portion and the water level difference between the heat storage tanks from occurring.
Also, since the above function is realized by the water permeable pipe installed at the bottom of the heat storage tank, the construction is easy, and the piping can be planned by the pipe resistance using water as a fluid. is there.

FIG. 1 is a plan view of a heat storage tank 1 in an ice storage system of an ice heat storage system according to an embodiment, and FIG. 2 is a main view of the ice storage system. FIG. 3 is an explanatory view of components, and a heat storage tank 1 in the present embodiment is a heat storage tank using, for example, an underground slab.
As shown in FIG. 1, the water intake tank 5 and the tanks 6, 7, and 8 are provided through the partition walls 2, 3, and 4, respectively.

At the bottom of the water intake tank 5, an intake chamber 1 is provided.
1 is provided. The water intake chamber 11 has an upper surface formed of a water permeable plate 12 made of, for example, a punched plate, and a granular filter medium 13 is spread over the water permeable plate 12 in a multilayered manner. In this case, for example, when a 1 mm diameter punching plate is used as the water permeable plate 12, gravel of about 2 to 3 mm may be spread first, and fine gravel may be spread sequentially from above. A water intake 15 a of a water intake pipe 15 for taking water from the water intake tank 5 by the pump 14 is arranged in the water intake chamber 11.

The heat source water taken in by the water intake pipe 15 is supplied to a supercooler 16 installed outside the heat storage tank 1. Then, the heat source water supplied to the subcooler 16 is discharged into the atmosphere as supercooled water of 0 ° C. or less,
Further, the discharge flow of the supercooled water falls into the vertical pipe 17.

The vertical pipe 17 has a vertical pipe structure having an inner diameter sufficient to receive the discharge flow of the supercooled water. The lower end communicates with the transport pipe 19. The impact when the supercooled water falls into the vertical pipe 17 generates an ice / water slurry composed of fine ice and water having fluidity.

The ice / water slurry conveyed by the conveying pipe 19 is supplied to the water supply tank 5 and the corresponding supply pipes 25, 26, 27 and 28 via on-off valves 21, 22, 23 and 24, respectively. The tanks 6, 7 and 8 are supplied. A water permeable pipe 31 is laid at the bottom of each of the tanks 6, 7, and 8. This permeable pipe 31
As shown in FIG. 3, it has a structure in which a punching plate provided with a large number of holes 32 is formed into a cylindrical shape, and the diameter of the holes 32 is set to 1 mm and the pitch thereof is set to 2 mm. .
That is, the entire periphery of the water permeable pipe 31 in this embodiment forms a water permeable portion. The diameter of the water permeable pipe 31 is the same as the diameter of the communicating portion of the heat storage tank 1.
Is determined by setting the pressure loss of the flow path according to the difference in the water level.

The permeable pipe 31 penetrates the lower part of the partition walls 2, 3, and 4 in the heat storage tank 1 so that the tank 6,
An opening / closing valve 33 is provided at the bottom of the partition 7, 8, and at one end opening 31 a located below the partition 2.

The ice storage system according to the present embodiment has the above-described structure. When the ice making and ice storage operation is normally performed at night, the operation of the pump 14 is performed with the on-off valve 33 opened.
The heat source water taken from the water intake tank 5 is converted into supercooled water by the supercooler 16 and ice / water slurry is generated by the vertical pipe 17.

The generated ice / water slurry is supplied to a supply pipe 19.
Is supplied to the water intake tank 5 and each of the tanks 6, 7, 8 through which the ice is stored. At this time, the supply to each of the water intake tanks 5 and each of the tanks 6, 7, 8 is performed by the corresponding on-off valve 21,
By the operations of 22, 23 and 24, it is possible to uniformly supply these tanks or to sequentially supply them by opening only one valve.

In the case of simultaneous supply, in the course of ice storage, a difference in the amount of ice stored between the water intake tank 5 and each of the tanks 6, 7, and 8 occurs due to a difference in pipeline resistance. Since the pressure loss due to ice increases in an enlarged tank, in such a case, the amount of ice stored is still small, and ice flows into a small tank having a small pipe resistance. That is, since the ice is always supplied to the tank having a small ice storage amount, even if there is a slight difference in the ice storage amount between the water intake tank 5 and each of the tanks 6, 7, and 8 during the ice storage. , Finally the water intake tank 5 and each of the tanks 6, 7,
8, ice is stored almost uniformly. In this manner, ice is stored in the water intake tank 5 and each of the tanks 6, 7, and 8, while water is simultaneously taken from the water intake tank 5.

In that case, the water intake tank 5 and each tank 6,
7 and 8 are communicated with each other by a water permeable pipe 31. Since the water permeable pipe 31 has a large number of holes 32 formed around it,
When the heat source water in each tank flows into the water-permeable pipe 31 and flows into the water intake tank 5, the ice already in the tank is trapped by the water-permeable portion of the water-permeable pipe 31 and does not flow into the pipe. Therefore, when ice is stored, ice does not adhere to the inside of the water-permeable pipe 31, that is, the inside of the communicating portion, to form an ice layer. It is possible to operate the system stably.

Further, when water for a heat source is taken from the water inlet 15 a of the water intake pipe 15,
2. Since the water passing through the filter medium 13 is taken in, the ice nuclei in the tank are trapped by the water permeable plate 12 and the filter medium 13, so that the ice nuclei are not mixed into the taken water for the heat source and are supercooled. The vessel 16 can exhibit its function stably, and can generate supercooled water stably.

In this embodiment, an opening / closing valve 33 is provided at the end of the water-permeable pipe 31 on the side of the water intake tank 5. By closing the open / close valve 33, the water intake tank 5 is closed.
It is possible to drain only. Therefore, the operation for cleaning the water permeable plate 12 and the filter medium 13 after operating for a long time is extremely simple. Moreover, since the filter medium 13 is granular, the cleaning itself can be easily performed.

In view of such a series of operations, for example, the water permeable plate 12 has a bottom surface and a side wall at an end thereof.
If the filter medium 13 is packed in a substantially box body having an open upper surface, and the filter medium 13 is detachably configured as a ceiling portion of the water chamber 11, the filter medium 13 can be removed as it is during the washing as described above. It can be washed, and the work of regenerating the filter medium can be performed simply and quickly.

The heat storage tank 1 in the above embodiment has a water intake tank 5 and a plurality of tanks 6, 7, and 8 separated by partitions 2, 3, and 4. However, the present invention is not limited to this. The present invention is applicable to a so-called independent multi-tank type heat storage tank in which each tank is located at a remote place. The permeation pipe used in such a case is different from the above-described embodiment, and a pipe material as shown in FIG. 3 is used for a part located in the tank, and a part for connecting a part between the tanks is usually used. What is necessary is just to lay so that these may be used and these may be connected.

In the above embodiment, the present invention is practiced by newly constructing a heat storage tank. However, the present invention can be easily applied to existing operating equipment. For example, as shown in FIG. 4, the heat storage tank 41 of the cold / hot water multiple tank type in the existing ice heat storage system includes partition walls 42, 43, 4.
The tanks 45, 46, 47, and 48 are communicated with each other by the openings 42a, 43a, and 44a provided in the nozzle 4. The openings 42a, 43a, and 44a are formed alternately in the vertical direction with respect to the partition walls. They are arranged in a staggered pattern.

In such a case, first, each of these openings 42
a, 43a, and 44a are covered with communication chambers 42b, 43b, and 44b, respectively, extending to the bottom of the tank. Each of these communication chambers 42b, 43b, 44b is
1, and an opening / closing valve 49 may be provided in the opening 42a. In FIG. 4, members indicated by the same reference numerals as those in FIG. 2 indicate the same members as those in the above-described embodiment.

When the heat storage tank 41 having such a configuration is used, the same effect as that of the above-described embodiment is obtained. When the water for the heat source is taken by the water intake pipe 15, the ice in the tank is placed in the water-permeable pipe 31. Is not mixed, and the system can be operated stably. In addition, since the openings 42a, 43a, and 44a serving as communication portions are arranged in a “staggered” shape, it is of course possible to use the same as a conventional cold / hot water tank.

Further, without using the water permeable pipe 31 as described above, for example, as shown in FIG.
The heat storage tank 51 may be configured such that the heat storage tanks a, 43a, and 44a themselves are covered with water-permeable chambers 42c, 43c, and 44c in which a large number of holes formed by a punching plate, expanded metal, and the like are formed.

Even when such a heat storage tank 51 is used, since the openings 42a, 43a, and 44a serving as communication portions are covered with the water-permeable chambers 42c, 43c, and 44c, ice in the tank adheres to the communication portions. Since this does not block the water, the passage resistance of the heat source water in the tank does not increase. Also, in the case of the heat storage tank 51, as in the case of the heat storage tank 41, the heat storage tank 51 can be used as it is as a cold / hot water tank. Further, as can be seen from the above embodiments, when the present invention is implemented, it is possible to easily perform the construction using a water-permeable pipe and a water-permeable plate having a simple configuration.

[0041]

According to the present invention , since it is sufficient to take water from one of the communicating heat storage tanks, the system can be simplified, including the piping of the water intake system. In addition, since it is possible to prevent ice from adhering to the communicating portion and to generate a water level difference between the heat storage tanks, it is possible to operate the system stably. Moreover, since it can be realized by a simple construction such as installing a water permeable pipe at the bottom of the heat storage tank, the construction is also easy, and the piping can be planned by the resistance of the pipeline using water as a fluid.

[0042]

[0043] In addition, be capable of easily filter media playback, such as by washing with water, it is easy to manage. In addition, as described above, for example, it is only necessary to take water from one of the communicating heat storage tanks, so that the maintenance and the system are simplified.

Furthermore , it is possible to drain only the water intake tank that is taken in for supply to the subcooler,
Removal of filter media for regeneration, replacement, etc. can be easily performed, and maintenance and management are further facilitated.
