Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal storage tank used in, for example, a thermal storage type air conditioning system and, more particularly, to a connected temperature stratified thermal storage tank in which a plurality of storage tanks for storing a liquid thermal storage medium are connected. .

[0002]

2. Description of the Related Art Conventionally, heat source equipment has been used at night to reduce the capacity and operating cost of heat source equipment by absorbing fluctuations in air conditioning loads of buildings and the like, and to save energy by operating heat source equipment with high efficiency. A regenerative air-conditioning system has been adopted in which cold water, hot water, and the like, generated by operating a full load, are stored in a heat storage tank and are used as a heat medium to be supplied to a secondary device such as an air conditioner.

When such a thermal storage type air-conditioning system is employed, it is common to use a double-layered underground slab space of a building to be air-conditioned as a thermal storage tank. As shown in FIG. 5, a plurality of storage tanks 52 partitioned by underground beams 51 are used.
Are connected type heat storage tanks connected in series via a communication hole 53 formed in the underground beam 51.

As shown in FIG. 6, an S-shaped communication pipe 54 as a rectifying means is provided in a communication hole 53 formed in an underground beam 51 for partitioning each storage tank 52, as shown in FIG. The S-shaped communication pipe 54 provides one storage tank 52.
By guiding the heat storage medium from the upper part of the storage tank 52 to the lower part of the adjacent storage tank 52 or from the lower part of the other storage tank 52 to the upper part of the one storage tank 52, the high temperature stored in the storage tank 52 is increased. There is a so-called connected-temperature stratified-type heat storage tank 50 that moves the heat storage medium using a temperature difference while minimizing the mixing of the heat storage medium and the low-temperature heat storage medium.

[0005] Further, since the above-described connected-temperature stratified-type heat storage tank 50 has a plurality of storage tanks 52, it is shown in FIG. 1 to check and clean each storage tank 52. As described above, it is desirable to install a maintenance manhole 55 for each storage tank 52, but it may be difficult to install the manhole 55 for each storage tank 52. In such a case, FIG. As shown in FIGS. 7 (a) and 7 (b), a human passage hole 56 is separately provided in the underground beam 51 that separates the storage tank 52 provided with the manhole 55 from the storage tank 52 provided with no manhole. An operator who has entered the installed storage tank 52 can be directly moved to the storage tank 52 where the manhole 55 is not installed through the human hole 56. Since the human through-hole 56 is not used except during inspection, it is usually closed by a plate 57 or the like so that it can be removed at the time of inspection or the like.

[0006]

In the connection temperature stratified heat storage tank 50 as described above, the heat storage medium is gently moved so as not to mix the high-temperature heat storage medium and the low-temperature heat storage medium. Underground beam 5
The communication hole 53 formed at 1 generally has a relatively large diameter through which a human can pass in order to reduce the flow rate of the heat storage medium. Therefore, if the communication hole 53 having such a large diameter can be used as a human through hole, it is not necessary to separately form the human through hole 56 in the underground beam 51, and the hole to the underground beam 51 leading to a decrease in strength is not required. Formation can be minimized.

However, in the connection temperature stratified type heat storage tank 50 as described above, the communication hole 53 has
Since the V-shaped communication pipe 54 is provided, the communication hole 5
It is difficult to use 3 as it is as a human hole,
At present, it is necessary to separately provide a human communication hole other than the communication hole 53.

Therefore, an object of the present invention is to form a separate through hole in a partition that partitions each storage tank, even if a maintenance manhole cannot be installed in each storage tank. An object of the present invention is to provide a connection temperature stratified heat storage tank which is not necessary.

[0009]

In order to solve the above-mentioned problems, the present invention is directed to forming a plurality of storage tanks for storing a liquid heat storage medium, which are partitioned by a partition, in the partition. The heat storage medium that is connected through the communication hole and moves between the adjacent storage tanks through the communication hole, from the upper part of one storage tank to the lower part of the other storage tank, or the other. Rectifying means for guiding from the lower part of the storage tank to the upper part of one of the storage tanks, in a connection temperature stratified type heat storage tank installed at a connection part of each storage tank,
A part or all of the rectifying means respectively installed in the connection part of each storage tank is installed so as to surround the opening end of the communication hole opened in one of the storage tanks, so that one of the communication holes and one of the rectification means are provided. The upper side flow path forming member that forms the flow path of the heat storage medium between the upper part of the storage tank, and the other by installing so as to surround the opening end of the communication hole opened to the other storage tank. A lower-side flow path forming member that forms a flow path of the heat storage medium between the communication hole and the lower part of the other storage tank; and the upper-side flow path forming member and the lower-side flow path forming member. The enclosed communication hole is formed to have a size that allows a human to pass through, and the upper channel forming member and the lower channel forming member each have a surface facing the opening end of the communication hole. In addition, a human doorway that can be opened and closed was formed.

[0010] In the connected temperature stratified type heat storage tank configured as described above, if the entrances and exits formed in the upper flow path forming member and the lower flow path forming member, which are rectifying means, are closed, for example, the adjoining ports are formed. When the heat storage medium moves from one storage tank to the other storage tank, the upper heat storage medium in the one storage tank in which the upper flow path forming member is installed has the flow formed by the upper flow path forming member. Through the passage and the communication hole, to the other storage tank side where the lower flow path forming member is installed, and through the flow path formed by the lower flow path forming member, to the lower side of the other storage tank. The heat storage medium is released.

Conversely, when the heat storage medium moves from the other adjacent storage tank to the one storage tank, the lower heat storage medium in the other storage tank in which the lower flow path forming member is installed is moved to the lower flow path. Through the flow path and the communication hole formed by the forming member, move to one storage tank side where the upper side flow path forming member is installed, and through the flow path formed by the upper side flow path forming member The heat storage medium is discharged to the upper side of one storage tank.

In addition, when performing maintenance and inspection of the storage tank,
For example, after performing maintenance and inspection while entering one of the adjacent storage tanks, when opening the entrance of the upper side flow path forming member or the lower side flow path forming member installed in the storage tank, communication with the entrance / exit is performed. Since the hole is in a state of facing, it moves into the flow path formed by the lower side flow path forming member or the upper side flow path forming member installed in the other storage tank through the communication hole from the entrance / exit, When the entrance of the lower-side channel forming member or the upper-side channel forming member is opened, it is possible to enter the other storage tank.

As described above, in this temperature-stratified heat storage tank, the adjacent storage tank passes through the flow path formed by the upper side flow path forming member and the lower side flow path forming member that constitute the communication hole and the rectification means. Even if it is not possible to install a maintenance manhole for each storage tank, it is not necessary to separately form a human through hole in the partition body, and holes formed in the partition body can be moved back and forth. Can be minimized.

Further, as in the temperature stratified type heat storage tank according to the second aspect, it is possible to lock in a closed state the entrances and exits respectively formed in the upper flow path forming member and the lower flow path forming member. A door is provided, and a lock operation portion is provided outside the formed flow path on one of the upper side flow path forming member and the lower side flow path forming member, and the other door is formed on the other side of the door. If a lock operation part is provided inside the flow path, the lock will be released if it moves from one of the adjacent storage tanks to the other storage tank and returns to the other storage tank again Then, the moving operation between the storage tanks, such as moving while opening each door and returning while closing and locking the opened door, can be performed smoothly.
