[0002]

2. Description of the Related Art Conventionally, the above-mentioned heat storage equipment has been used, for example, for air conditioning of a living space, and the performance of these heat storage equipment is mainly evaluated by the heat storage capacity. for that reason,
In conventional heat storage equipment, many heat storage materials are often arranged side by side or stacked to increase the heat storage capacity. When these heat storage facilities are installed in a building, the heat storage facilities are often installed in the underfloor space due to the storage space and the weight of a large number of heat storage materials. At that time, prior to the formation of the floor, the cooling / heating device, the circulation driving device, the plurality of heat storage materials and the like are arranged at predetermined positions, and the respective members are interconnected. Then, after completing the installation in the heat storage facility, the floor of the building is constructed.

[0003]

However, in the case of the above-mentioned conventional heat storage equipment, if the heat storage equipment is to be installed in a building that has already been completed, a wide area of the floor must be temporarily removed. In addition, the installation of heat storage equipment becomes very complicated. Further, once the heat storage equipment is installed and the floor is constructed, it is very troublesome to remove the floor again, so that the maintenance of the heat storage equipment cannot be performed substantially.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a heat storage facility which is easy to install and take out and which is easy to maintain.

[0005]

Means for Solving the Problems [Configuration 1] In the heat storage equipment of the present invention, a circulating drive device, a cooling and heating device, and a heat storage unit are arranged respectively, and along the direction in which they are arranged. It is characterized in that it has a connecting means that can be connected and disconnected. [Effects] According to the present configuration, for example, even in a narrow space that spreads only in a planar shape, heat storage equipment can be installed and taken out along the expansion direction of the space. Therefore, it is possible to assemble and disassemble the heat storage equipment from a specific work place while effectively utilizing the space in the building. As a result, it is possible to provide a heat storage facility that is easy to install and take out and that is easy to maintain.

[Structure 2] The heat storage equipment of the present invention is characterized in that
As described in above, a configuration having a plurality of the heat storage units can be adopted. [Effects] With this configuration, as long as it has a plurality of heat storage units, the heat storage capacity can be increased by the number of heat storage units. That is, in the heat storage equipment of this configuration, by connecting a predetermined number of heat storage units,
A heat storage facility having a required heat storage capacity can be obtained.
Therefore, it is possible to obtain a heat storage facility having a high degree of freedom in design according to the scale of a building or the like while using heat storage units of the same size.

[Structure 3] The heat storage equipment of the present invention is characterized in that
As described in the above, a buckle provided between members to be connected to each other can be used as the connecting means. [Effects] The buckle normally connects the locking member and the locked member, which are separately allocated to the members to be connected, while engaging the locking member and the locked member. By using such a buckle, the members to be interconnected can be sufficiently fitted, for example. As a result, it is possible to form a fluid flow path in which leakage of fluid circulated for air conditioning is prevented. In addition, the worker who performs the connection work will be able to obtain a sufficient response to operate the buckle, and thus can confirm that both members have been securely connected.

[Structure 4] The heat storage equipment of the present invention is characterized in that

[Effects] For example, a locked member and an elastic locking member are separately provided for each of the members connected to each other, and the locked members are elastically deformed by bringing both members close to each other and elastically deforming the elastic locking member. As long as the unit is engaged with the member, it is possible to connect both by simply pushing one of the units to be connected. Therefore, the work of connecting members in a narrow place becomes extremely simple. In addition, since the structure and mounting method of the elastic locking member are particularly simple, economical connecting means can be obtained.

[Structure 5] The heat storage equipment of the present invention is characterized in that
As described in above, a magnet can be provided between the members that are connected to each other as the connecting means. [Effects] If the connecting means is constituted by a magnet as in the present configuration, the structure of the connecting means becomes very simple. In addition, since the connecting operation is only required to simply move the two members close to and away from each other, the connecting operation of the heat storage unit or the like in a narrow place becomes extremely easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (Summary) FIG. 1 shows an example of a heat storage facility according to the present invention. The heat storage facility includes a cooling and heating device H for cooling and heating a fluid for air conditioning, and a heat storage unit Y for storing heat using a fluid separately from the cooling and heating device H. An example is shown in which air A is used as the fluid in the present embodiment. The heat storage unit Y incorporates a plurality of heat storage capsules 1. Further, the heat storage capsule 1
Is filled with a heat storage material 2 capable of storing and radiating heat by heat exchange with the air A.

The air A that has exchanged heat in the cooling / heating device H or the heat storage unit Y can be circulated and flown inside the heat storage facility or between the heat storage facility and the air conditioning space 3 by the circulation driving device J. At that time, the circulation flow
The operation mode switching means S can switch between two modes, a heat storage mode in which heat is stored in the heat storage material 2 and a heat release mode in which air conditioning of the air-conditioned space 3 is performed using the heat storage.
And in the heat storage equipment of the present invention, the circulation drive device J,
In addition, the cooling and heating device H and the heat storage unit Y are arranged side by side. These members can be connected and disconnected by the connecting means R, and are configured to be connected and disconnected along the direction in which they are arranged. In FIG. 1,
Although an example in which these members are arranged in a U-shape has been described, it is a matter of course that these members may be arranged in series, and the arrangement state can be appropriately changed according to the arrangement space of the heat storage facility.

(Cooling and heating device) In the heat storage equipment, air A for air conditioning or heat storage is cooled and heated by a cooling and heating device H. For this, for example, the heat exchanger 4 of a normal heat pump type air conditioner can be used. Although not shown, the heat exchanger 4 includes a compressor that pressurizes the heat medium circulated through the heat exchanger 4 or an expander that depressurizes the heat medium. These compressors etc.
Usually, an outdoor unit is provided at a position away from the heat storage facility.

At the time of cooling and heating, the air A is supplied to the first heat exchanger 4 adjacent to the heat exchanger 4 as one of the circulation driving devices J.
The fluid is caused to flow using the fan 5. As the first fan 5, for example, a sirocco fan or a cross flow fan is used. The air A is circulated through the heat exchanger 4 by the fan, and the air A is cooled and heated to a predetermined temperature.

The cooling and heating device H operates by, for example, inverter control. That is, when the air-conditioning space 3 is air-conditioned, if the temperature difference between the set temperature for air-conditioning and the temperature of the air A is large, or if the available heat storage amount is small, the operation output of the heat exchanger 4 is increased to operate. . On the other hand, when the temperature difference between the set temperature and the air A is small or when the available heat storage amount is large, the operation output of the heat exchanger 4 is reduced to operate.

As the cooling / heating device H, a heat exchanger 4 of a heat pump type air conditioner can be used as described above, or a general cooling device or heating device may be used.

(Heat storage unit and heat storage material) The heat storage unit Y stores heat using the air A cooled and heated by the cooling and heating device H. The heat storage unit Y incorporates a plurality of heat storage capsules 1. The heat storage capsule 1 is formed of, for example, a plate-shaped member as shown in FIG. Of course, other shapes may be used, such as a spherical shape, a spherical shape having dimples, and an oval shape. These heat storage capsules 1 each have an internal space in which a heat storage material 2 described later can be filled.

The heat storage capsule 1 can be juxtaposed inside the heat storage unit Y. A flow path through which the air A can flow is formed between the heat storage capsules 1 arranged adjacent to each other. The heat storage capsule 1 is made of, for example, polyethylene, metal, such as ordinary steel, aluminum, and copper.
It can be configured using a synthetic resin such as polypropylene.

The heat storage capsule 1 is filled with a heat storage material 2 capable of storing and releasing heat by exchanging heat with the air A. Examples of the heat storage material 2 to be filled in the heat storage capsule 1 include a mixture of calcium chloride hydrate and water,
Alternatively, low melting point plastics, paraffins,
It can be constituted by using a material such as wax that utilizes latent heat that undergoes a phase transformation with the absorption and release of heat. Thus, the heat storage material 2 that absorbs and emits heat during the phase transformation
When the heat storage material 2 is used, for example, a large heat absorption / discharge amount per unit mass of the heat storage material 2 can be secured. Moreover, it can also be configured using a material that simply uses sensible heat, such as a stone, various metals, and a cement board.

In this embodiment, an example is shown in which two types of heat storage materials 2 for cooling and heating are used as such heat storage materials 2. For example, a material having a low phase transformation temperature that undergoes phase transformation at about 0 ° C. is used for cooling, and a material having a high phase transformation temperature that undergoes phase transformation at about 50 ° C. is used for heating. If such two kinds of heat storage materials 2 are simultaneously filled in the heat storage capsule 1, the heat storage equipment can be used for both cooling and heating, which is convenient.

In constructing the heat storage equipment of the present invention, the number of the heat storage units Y can be arbitrarily determined. FIG. 1 shows an example in which three heat storage units Y are used, but by using a plurality of heat storage units Y in this manner,
The heat storage capacity can be set as appropriate. In other words, the heat storage capacity can be freely set by appropriately changing the number of heat storage units Y having the same shape and connecting them.

In the heat storage unit Y, air A flowing inside the heat storage unit Y is filled with all the heat storage capsules 1.
A flow rectifying plate P can be attached as shown in FIG. The current plate P is made of, for example, a punching metal provided with a large number of holes. By forming a substantially uniform flow rate of the air A around the heat storage capsule 1 in this manner, all the heat storage materials 2 can function effectively. However, the current plate P
Need not be provided for all connected heat storage units Y. For example, when connecting a plurality of heat storage units Y, the heat storage units Y may be provided at least on the front side of the heat storage unit Y through which the flowing air A first passes.

(Circulation drive unit) The air A that has exchanged heat in the cooling / heating unit H or the heat storage unit Y is supplied to the circulation drive unit J inside the heat storage unit or between the heat storage unit and the air conditioning space 3. Can be circulated and fluidized. At this time, the circulating flow can be switched by the operation mode switching means S to two modes, a heat storage mode for storing heat in the heat storage material 2 and a heat dissipation mode for air-conditioning the air-conditioned space 3.

As shown in FIG. 1, the circulation driving device J
Is composed of a first fan 5 and a second fan 6 provided separately. The first fan 5 is disposed adjacent to the cooling and heating device H, and is used mainly in the heat storage mode. The second fan 6 is provided at the base end of the outlet channel 7 that supplies air A from the heat storage unit Y to the air-conditioned space 3, and is mainly used in the heat dissipation mode. However, switching to the heat storage mode or the heat dissipation mode is performed by appropriately adjusting the drive output of the first fan 5 and the second fan 6 instead of using only one of the fans. The specific mode will be described later.

(Connecting Means and Connection Mode) In the heat storage equipment according to the present invention, the circulation drive device J, the cooling / heating device H, and the heat storage unit Y are used in a state where they are juxtaposed. In many cases, the members are arranged substantially in a plane. For example, it is often arranged side by side under the floor. Of course, it may be provided in the space behind the ceiling or inside the wall. In order to efficiently arrange a plurality of units in such a place, it is preferable to lay a carrying rail 8 on the grounding surface as shown in FIG. As the rail 8, for example, two L-shaped angle members are juxtaposed so as to hold the unit to be connected, and the unit is slid along the inner surface thereof. Although not shown, when installing the unit, the unit can be pushed in using, for example, a pushing rod or the like. In the case of removing each unit, although not shown, a pulling line is attached to each unit in advance, and after the connection state of the connecting means R is released, the pulling line is pulled. It can be.

With the above-described configuration, it is possible to reliably perform alignment between the connected units. The heat storage equipment of the present invention having such a configuration can provide the heat storage equipment even in a narrow place where the heat storage equipment can be spread only in a planar shape, and the installation work and the removal work are easy and the maintenance is easy. can do.

In the present embodiment, FIGS.
As shown in the figure, the first connecting means R of the connecting means R
An example using a buckle as 1 is shown. Here, an example in which the heat storage units Y are connected to each other will be described. The buckle is
As shown in FIG. 3, it has a locked member 9 and a locking member 10. The locked member 9 is simply the outer peripheral surface 11 of the heat storage unit Y or the like.
It just doesn't work.

On the other hand, the locking member 10 is mainly composed of a retraction member 13 having a locking pin 12 for locking the locked member 9.
And a swing handle 14 pivotally supported by the other heat storage unit Y to operate the drawing member 13. Further, an urging spring 15 is attached to a part of the drawing member 13 along the outer peripheral surface 11 of the heat storage unit Y.
The retracting member 13 is moved by the urging spring 15 to the outer peripheral surface 1.
Attract to one side.

FIG. 3A shows a released state before connecting both heat storage units Y. In this state,
The swing handle 14 is substantially perpendicular to the outer peripheral surface 11 of the heat storage unit Y. That is, the swing handle 14
Is pulled toward the existing heat storage unit Y by the biasing spring 15 and the pull-in member 13, but the swing handle 14
The stopper 16 provided at the base of the heat storage unit Y comes into contact with the outer peripheral surface 11 of the heat storage unit Y to prevent the swing handle 14 from falling down.

FIG. 3B shows a tightened state in which both heat storage units Y have been connected. In this state, the swing handle 14 is tilted in the opposite direction to the existing heat storage unit Y, and is in contact with the outer peripheral surface 11 of the heat storage unit Y. In this state, the biasing spring 15 is over-centered with respect to the pivot pin 17 fixing the swing handle 14. In other words, the mounting position of the biasing spring 15 in the retracting member 13 is displaced from a position above the pivot pin 17 to a position below the pivot pin 17 with the swing, whereby the swing by the bias spring 15 is performed. The biasing direction of the handle 14 is changed. As a result, the swing handle 14 is urged toward the outer peripheral surface 11 of the heat storage unit Y, and fixes the swing handle 14 at the tightened position.

The operation of the swing handle 14 is performed, for example, by pulling a pull cord 18 provided at the tip of the swing handle 14. Accordingly, even when the heat storage unit Y or the like is arranged in a place where it is difficult for an operator to enter, such as under the floor, the heat storage unit Y
Can be easily connected. The heat storage unit Y
Is released, the tip of the swinging handle 14 may be pushed in the direction opposite to the pulling direction. At this time, if, for example, a hollow rod-shaped member is externally inserted into the pull cord 18, the rod-shaped member can be reliably brought into contact with the tip of the swinging handle 14, and the buckle detaching operation can be easily performed. It can be carried out.

When the connecting means R having such a configuration is used, the swing handle 14 is directly operated by the drawstring 18.
Therefore, the operator can obtain a response when applying the pulling force for locking, and can confirm that the locking has been securely performed. Also, with the operation of the swing handle 14,
Since the locking pin 12 pulls the locked member 9, the members to be interconnected can be sufficiently fitted. As a result, a flow path of air A without leakage can be formed.

(Fitting Part) A fitting part 19 is formed between the members to be connected. In FIG. 3, a concave fitting portion 19a is formed at the end of the heat storage unit Y already installed, and a convex fitting portion 19b is formed at the end of the heat storage unit Y to be connected later. In addition, as shown in FIG. 3, an inclined portion 20 is formed in both fitting portions 19. Thereby, the convex fitting portion 19b of the heat storage unit Y connected later can be easily inserted into the concave fitting portion 19a of the existing heat storage unit Y.

Further, as shown in FIG. 3, a seal member 21 for improving the sealing property of the connection portion is attached to the inner peripheral surface of the concave fitting portion 19a. Specifically, a circumferentially continuous groove portion 22 is formed on the inner peripheral surface of the concave fitting portion 19a, and a ring-shaped seal member 21 is fitted into the groove portion 22 in advance. That is, when the connection is completed, the seal member 21 is placed between the inner peripheral surface of the concave fitting portion 19a and the outer peripheral surface 11 of the convex fitting portion 19b.
Will be pinched.

(Operation Mode of Heat Storage Facility) In the heat storage facility of the present invention, the operation mode can be roughly divided into three. That is, an operation mode in which heat is stored in the heat storage unit Y, an operation mode in which heat is released from the heat storage unit Y, and a mode in which air conditioning of the air-conditioned space 3 is performed using only the cooling and heating device H without using the heat storage unit Y. It is.

FIG. 4 shows an operation mode involving heat storage in the heat storage unit Y. This mode is called a heat storage mode in a broad sense. The heat storage modes are further classified into a pure heat storage mode in which only heat storage is completely performed, and a (heat storage + air conditioning) mode in which heat storage and air conditioning of the air-conditioned space 3 are simultaneously performed. In order to switch between these modes, the three shutters 23 are appropriately switched in this embodiment. The shutter 23 forms a part of the operation mode switching means S.

FIG. 4 shows an operation state in the (heat storage + air conditioning) mode. All shutters 23a, 23
b and 23c are open. However, in this mode,
It is necessary to set the air volume of the first fan 5 larger than the air volume of the second fan 6. In this state, an air flow circulating between the cooling and heating device H and the heat storage unit Y and an air flow circulating between the cooling and heating device H and the air conditioning space 3 are formed. That is, since the amount of air flowing through the first fan 5 is larger than the amount of air flowing through the second fan 6, air that cannot flow through the second fan 6 bypasses the heat storage unit Y. As a result, the cooling and heating device H and the heat storage unit Y
Heat is stored in the heat storage unit Y by the air flow circulating between the air conditioning space and the air conditioning space 3 can be directly air-conditioned by the air flow circulating between the cooling and heating device H and the air conditioning space 3.

Although illustration is omitted, the state shown in FIG.
When the shutter 23c is closed, only the air flow circulates between the cooling and heating device H and the heat storage unit Y, and the air flow is in the pure heat storage mode. The fan operates only the first fan 5. By setting the cooling and heating device H to an arbitrary temperature, the heat storage unit Y can store cold or warm heat.

FIG. 5 shows an operation mode in which the air-conditioning space 3 is air-conditioned by utilizing the heat radiation from the heat storage unit Y. This mode is referred to as a heat radiation mode in a broad sense. However, the heat dissipation mode further includes a pure heat dissipation mode in which the air conditioning space 3 is air-conditioned only by heat dissipation, and a cooling and heating device H in addition to heat dissipation.
(Air-conditioning + air-conditioning) mode in which the air-conditioned space 3 is air-conditioned using the heat generated in step (1). Switching of these modes is also performed by the three shutters 23a, 23b, and 23 described above.
This is performed by the switching operation of c.

FIG. 5 shows an operation state in the (radiation + air conditioning) mode. All shutters 23a, 23b, 2
3c is an open state. In this mode, the amount of air blown by the second fan 6 is set to be larger than the amount of air blown by the first fan 5. The direction of the air flow circulating in the heat storage unit Y is opposite to that in the (heat storage + air conditioning) mode.
In this state, the air-conditioned space 3 can be air-conditioned by the airflow circulating between the heat storage unit Y and the air-conditioned space 3, and the air-conditioned space is circulated between the cooling and heating device H and the air-conditioned space 3. 3 can be directly air-conditioned.
This mode can be used, for example, when the consumption of heat storage is advanced and air conditioning using only heat storage is insufficient, and the air conditioning of the air-conditioned space 3 is to be assisted by the cooling and heating device H.

Although illustration is omitted, the first state is changed from the state shown in FIG.
When the shutter 23a is in the closed state, the air flow only circulates between the heat storage unit Y and the air-conditioned space 3,
It becomes pure heat dissipation mode. The fan operates only the second fan 6. The operation in the pure heat dissipation mode is performed when it is desired to preferentially consume the heat storage of the heat storage unit Y.

FIG. 6 shows a mode in which the air conditioning space 3 is air-conditioned using only the cooling and heating device H without using the heat storage unit Y. This operation mode is particularly called a pure air conditioning mode. In the pure air-conditioning mode, for example, if no heat is stored in the heat storage unit Y, the air-conditioned space 3
Is used immediately when it is desired to air-condition, or when it is desired to air-condition the air-conditioned space 3 while keeping the heat storage of the heat storage unit Y. In this mode, the first shutter 23a and the third shutter 23c are opened, and the second shutter 23b is closed. The fans are the first fan 5 and the second fan 6
Both of them are activated. As described above, the heat storage facility of the present invention can be operated in any mode, and can perform air-conditioning without waste according to the user's request.

(Effects) As described above, the heat storage facility of the present invention provided with the circulation drive device, the cooling / heating device, and the heat storage unit, and the connection means capable of connecting and disconnecting along the direction in which they are arranged. For example, even in a narrow space that spreads only in a planar shape, a heat storage facility can be installed and taken out along the spreading direction of the space. Therefore, it is possible to assemble and disassemble the heat storage equipment from a specific work place while effectively utilizing the space in the building. As a result, it is possible to provide a heat storage facility that is easy to install and take out and that is easy to maintain.

(Another Embodiment) <1> FIGS. 7A and 7B show an example of the connecting means R2 according to the second embodiment of the connecting means R. FIG. That is,
The elastic locking member 10a and the locked member 9 may be separately provided over the heat storage units Y connected to each other. The connection means R according to this embodiment connects the two units by simply pressing the newly connected heat storage unit Y against the existing heat storage unit Y, for example. As shown in FIG. 7A, a locked member 9 is attached to the existing heat storage unit Y, and an elastic locking member 10a is provided to the newly connected heat storage unit Y. The elastic locking member 10a may be formed of any material such as a metal, a synthetic resin, and a rubber as long as it is elastically deformable.

The elastic locking member 10a is attached to the outer peripheral surface 11 of the heat storage unit Y with a single screw member 25, for example. Thereby, the free side end of the elastic locking member 10 a can be moved toward and away from the outer peripheral surface 11 along the normal direction of the outer peripheral surface 11. The elastic locking member 1
The free end of Oa is rotatable around the axis X of the screw member 25. Further, a projection 26 is provided at an intermediate portion of the elastic locking member 10a to apply a tensile force at the time of detachment to separate the free side end from the outer peripheral surface 11.

When a new heat storage unit Y is brought close to the existing heat storage unit Y, the inclined surface 2 formed at the free end
7 comes into contact with the inclined surface 27 of the locked member 9. Further, when the elastic locking member 10a is pushed in, the free side end rides on the locked member 9, and then the locked member 9 and the elastic locking member 10a are engaged as shown in FIG. I do.

To release the engaged state, the protrusion 26 may be pulled in the direction opposite to the pushing direction, and the free end may be separated from the outer peripheral surface 11. In this pulling operation, for example, the protruding portion 26 may be pulled using a long member.
It is also possible to pull a pull cord for retraction that has been attached in advance.

Further, since the elastic locking member 10a is rotatable about the axis X of the screw member 25 for mounting, the protrusion 26 is moved in any direction along the outer peripheral surface 11. The engagement state can also be released by pressing the elastic locking member 10a.

According to this configuration, since the heat storage unit Y to be connected later can be simply pushed in, the connection operation of the heat storage unit Y and the like in a narrow place can be made extremely easy. In addition, since the structure and mounting method of the elastic locking member 10a are particularly simple, an economical connecting means R can be obtained.

<2> FIG. 8 shows an example of the connecting means R3 according to the third embodiment among the connecting means R. That is, for example, the magnet 28 may be provided over the heat storage units Y connected to each other. For example, the magnets 28 are embedded in the butting end surfaces 29 of the heat storage units Y, respectively. The attraction force at the time of connection can be appropriately set by selecting the magnitude of the magnetic flux density of the magnet 28, the number of magnets 28, or the like.

Also in the case of the connecting means R of this configuration, since the unit to be connected only needs to be pushed in, the work of connecting the heat storage unit Y and the like in a narrow place can be made extremely easy. Further, the structure and attachment method of the connecting means R are very simple, and the economical connecting means R can be obtained.

<3> In the above embodiment, the example in which the carry-in rail 8 is laid on the grounding surface has been described. However, for example, a universal wheel may be attached to the bottom of the heat storage unit Y or the like. Good. If the individual units such as the heat storage unit Y are configured to be movable, the work of connecting the units can be easily performed only by arranging the floor on which the heat storage equipment is arranged to some extent.

<4> The floor on which the heat storage equipment is installed is:
Usually, it is often a horizontal surface. However, the installation surface may be configured so as to be inclined downward in the direction in which each unit is taken out. In other words, if a down slope is given,
Each unit can be easily taken out even if the rope for taking out each unit comes off.
In addition, if a downward slope is given, even if the heat storage material 2 leaks or dew condensation water generated in the heat exchanger 4 flows out, it is possible to prevent water and the like from accumulating below the heat storage equipment. At the same time, such water and the like flows out to the inspection port side, so that occurrence of inconvenience can be found at an early stage.
In this manner, by making the installation surface inclined downward, it is possible to improve the reliability of the heat storage facility, for example, the work of taking out the heat storage facility becomes easy, and the trouble can be easily found.

<5> The arrangement of the heat storage unit Y and the cooling and heating device H is not limited to the embodiment shown in FIG. In the equipment shown in FIG. 1, for example, a heat storage operation and an air-conditioning operation can be performed simultaneously using the cooling and heating device H, and a parallel circuit is configured as viewed from a so-called heat medium flow path. However, the present invention is not limited to this example, and the air conditioning space 3 and the heat storage unit Y, the cooling and heating device H, and the like may be connected in series. In this case, it is also possible to switch between the heat storage operation and the air-conditioning operation using the heat storage by appropriately providing the bypass passage and the flow path switching damper to adjust the flow direction or the flow rate of the heat medium.

<6> In each of the above embodiments, an example in which air as a fluid is circulated as a heat medium for air conditioning has been described. However, a liquid such as water may be used. When a liquid heat medium having a larger heat capacity than air is used, the circulation path can be made narrower than when air is circulated. As a result, space saving of the heat storage facility can be achieved. When a liquid heat medium is used, it is necessary to reliably prevent leakage during circulation. Therefore, it is preferable that a buckle is used in the above-described connection means. Of course, any structure may be used as long as a reliable connecting portion can be obtained.
