[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a latent heat storage type air conditioning panel, and more specifically to a heat storage body in which a latent heat storage agent is enclosed in a panel for partitioning a space in a building. However, by using inexpensive late-night power at night, hot or cold heat is stored in the latent heat storage agent, and the stored hot or cold heat is radiated to the air in the building to which the air conditioning panel is applied during the daytime, and thus air conditioning is performed. Related to the improvement of the air conditioning panel.

[Conventional technology]

As is well known, the heat storage method using a latent heat storage agent has a large heat storage density as compared with sensible heat utilization technology, and it is possible to obtain a considerable amount of heat and to compact the device. Has come to be used in various technical fields. This heat storage means is also applied to members that partition the space in the building, specifically wall materials and panels. That is, in the technology proposed in JP-A-57-74590 and JP-A-61-197921, in the box-shaped body constituting the wall material, heat or cold heat at the phase change of melting or solidification. Is stored as latent heat,
It contains a latent heat storage agent which radiates heat storage heat or cold heat into the air at the time of phase change of solidification or melting. in this case,
In these conventional techniques, the latent heat storage agent is directly sealed and accommodated in the entire box-shaped body.

[Problems to be solved by the device]

The above-mentioned conventional technique is a useful technique in which the latent heat storage method is applied to a wall material, a panel, and the like, and since the latent heat storage agent is accommodated in the entire box-shaped body, the heat storage temperature per box-shaped body or It has an advantage that the amount of cold heat becomes large, however, as a result of some examinations made by the applicant, the following problems were found. That is, at the time of heat storage using late-night power or the like, the latent heat storage agent is heated or cooled by heating means such as a heater or cooling means such as a cooling pipe. At this time, the latent heat storage agent itself is densely accommodated in the box-shaped body. However, since it is in direct contact with the component of the box-shaped body, the heat or cold provided from the heating means or the cooling means easily escapes from the surface of the component of the box-shaped body into the air by conduction heat transfer. Heat loss is likely to occur during heat storage. The stored hot or cold heat is radiated into the air by bringing the air into contact with the surface of the box-shaped body that contains the latent heat storage agent. Since heat is exchanged between the latent heat storage agent and the air by causing convection, the heat exchange efficiency has a certain limit, and improvement has been required. In addition, since the latent heat storage agent is tightly accommodated in the box-shaped body, it is considerably difficult to manufacture and maintain the box-shaped body as a sealed structure, and the weight becomes large even during construction. It was troublesome to handle.

[Object] Therefore, the object of the present invention is to form an air passage between the heat storage member and the constituent members of the box-shaped body when the heat storage body is housed in the box-shaped body. By blocking the air passage from the air in the building space, it is possible to use the air layer in the air passage as a blocking layer, heating or cooling the latent heat storage agent under this adiabatic state, by storing hot or cold heat, It is to provide a means for reducing the heat loss during heat storage.

Further, during air conditioning, air is forcibly convected in the air passage around the heat storage body arranged inside the box-shaped body, heat exchange efficiency with the air in the building to be air-conditioned is improved, and better air conditioning conditions can be provided. To do so.

In addition, it is to provide a latent heat storage type air conditioning panel that is easy to manufacture, easy to maintain, and easier to handle during construction.

[Means for solving the problem]

In order to achieve the above object, the present invention has the following technical means. That is, the present invention will be described with reference to the reference numerals in the accompanying drawings corresponding to the embodiments. According to the present invention, a box-shaped body 1 contains a heat storage body 3 in which a latent heat storage agent 2 is enclosed, and partitions a building space as a whole. Formed in the shape of a panel for the purpose of melting or solidifying the latent heat storage agent 2 by the heating means or the cooling means 20 so that hot or cold heat can be stored, while the air in the space where the latent heat storage agent 2 is to be conditioned. In the latent heat storage type air conditioning panel, the latent heat storage agent 2 is solidified or melted by contacting with it to radiate the hot or cold heat previously stored to the air, thereby air-conditioning the inside of the building; When accommodating the heat storage body 3 in the body 1, the heat storage body 3 is housed so that the air passage 13 is formed between the heat storage body 3 and the constituent members of the box body 1 and Dampers 14 and 15 are installed in each of the upper and lower parts to store heat The upper and lower dampers 14 and 15 are closed so that the air layer in the air passage 13 around the heat storage body 3 can be used as a heat insulating layer for heat storage operation, and the respective dampers 14 and 15 are opened during air conditioning. Moreover, the blower 16 accommodated in the box-shaped body 1 is driven to pass the air through the air passage 13 in the box-shaped body 1, and the forced air convection makes it possible to radiate hot or cold heat from the heat storage body 3 to the air. This is a latent heat storage type air conditioning panel.

[Action]

Based on the above configuration, the latent heat storage operation is performed when cheap midnight power can be used. That is, the upper and lower dampers
14, 15 are closed, the blower 16 is stopped, and the latent heat storage agent 2 in the heat storage body 3 is heated or cooled by the heating means or the cooling means 20. Then, the latent heat storage agent 2 is melted or solidified at the melting or solidifying temperature, and hot heat or cold heat is stored as latent heat. Storing cold energy here means storing cold, and the same applies hereinafter.

By the way, at this time, the air layer in the air passage 13 between the surface of the heat storage body 3 and the box-shaped member functions as a heat insulating layer, so that this air layer is closed by closing the upper and lower dampers 14 and 15. Since it is confined in the body 1, the above heat storage operation is performed under a better heat insulation condition. Therefore heating or cooling means 20
The heat or cold applied from the latent heat storage agent 2 to the latent heat storage agent 2 is suppressed from being transferred to the surrounding air or other members by conduction heat transfer during heat storage. Therefore, the heat loss is small, the latent heat storage agent 2 having a predetermined capacity can be melted or solidified more quickly, and the electric power required for this can be reduced.

Furthermore, during air conditioning, the blower 16 is driven and the upper and lower dampers are
14,15 are opened. Therefore, the air in the space to be conditioned is forcibly convected through the air passage 13 around the heat storage body 3 in the box-shaped body 1. Therefore, the heat exchange efficiency between the heat storage body 3 and the air becomes good, and the hot or cold heat stored in the latent heat storage agent 2 is transferred to the air faster. Therefore, desired air conditioning conditions can be obtained quickly.

〔Example〕

 Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the first embodiment will be described in detail with reference to FIGS. Appendix A shows the entire latent heat storage type air conditioning panel.
As schematically shown in the figure, it is used to partition one space B and the other space C in the building. Of course, it is the main material of the partition that divides the space itself, or an additional component that is installed along with other main materials, and is typified by the terms wall material, partition material, partition, panel, etc. Means everything.

Referring now to FIG. 2 and subsequent figures, this example will be described in detail. The rectangular thin box-shaped body 1 including the main body 1a and the cover 1b is provided. A heat storage body 3 in which the latent heat storage body 2 is enclosed is housed in the main body 1a. In the example of this figure, a plurality of heat storage bodies 3 are provided in upper and lower three stages.
Is housed. The heat storage body 3 itself is shown as a plate.

When the heat storage body 3 is housed in the box-shaped body 1, the following is done. Since the method of accommodating the heat storage bodies 3 in the respective stages is the same, the description will be given focusing on one heat storage body 3, and the support members 6 are attached to the upper part 4 and the lower part 5 of the heat storage body 3, respectively. Then, both ends 7 of the support member 6 are fixed to the inner surface 7 of the side surface of the main body 1a which is a component of the box-shaped body 1, and the plate-shaped heat storage body 3 is held in the box-shaped body 1 in a suspended state. As a result, an air passage 13 is formed between the surface 9 of the heat storage body 3 and the inner surface 11 of the cover 1b forming the box-shaped body 1, and the main body 1a
An air passage 13 is also formed between the inner surface 12 and the back surface 10 of the heat storage body 3. In the illustrated example, an air passage is also formed between the side surface of each heat storage body 3 and the inner surface 8 of the side surface of the main body 1a. Then, a damper 14 that opens and closes as shown by an arrow W is provided on the upper part and the lower part of the box-shaped body 1. Moreover, a blower 16 is provided below the upper damper 14.
To arrange. Therefore, the inflow port 17 formed in the cover 1b is formed upstream of the upper damper 14, and the outflow port 18 also formed in the cover 1b is formed downstream of the lower damper 15 and the blower 16. Reference numeral 20 is a heating means inserted in the latent heat storage agent 2 in the heat storage body 3, for example, a heater type is a cooling means, for example, a cooling pipe.

The use operation will be described based on the above configuration. For convenience of description, an example is shown in which the latent heat storage agent 2 for heating, which stores warm heat by melting and radiates the stored warm heat by solidification, is used. Such a latent heat storage agent is selected because it is industrially available in large quantities and because the melt-solidification phase change is stable, and particularly in an operating temperature range suitable for the temperature to be air-conditioned. Things are selected. For example, those containing sodium acetate or sodium sulfate having a melting / solidifying temperature of 45 ° C to 55 ° C as a main component are considered.

By the way, at the time of heat storage, the upper and lower dampers 14 and 15 are closed and the drive of the blower 16 is stopped. In this state, the air layer in the air passage 13 is shielded from the outside and forms a heat insulating layer. Here, the latent heat storage agent 2 in the heat storage body 3 is heated by the heating means 20 such as a heater and melted at a temperature equal to or higher than the melting temperature thereof, and warm heat is stored as latent heat. In this case, it is preferable to use late-night power, which has a low power rate. And, heating means for this melting
At the time of heating by 20, the air layer in the air passage 13 is interposed as a heat insulating layer between the heat storage body 3 itself and the cover 1b or the main body 1a which is a constituent member of the box-shaped body 1. It is difficult for heat to be transferred to the box-shaped body 1 by conduction heat transfer, and the supplied heat amount is effectively used for melting the latent heat storage agent.

Therefore, the phase change can be applied to the latent heat storage agent faster, and the power consumption can be reduced accordingly.

Then, during air conditioning, the blower 16 is driven and the upper and lower dampers 14 and 15 are opened. In the case of this example, since it is shown for heating, the air in the building to be air-conditioned enters from the inlet 17 as indicated by arrow S, passes through each air passage 13 as indicated by arrow R, and the lower outlet 18 is provided. It flows out like arrow T.

In the process of forced air convection, the latent heat storage agent 2 in the heat storage body 3
Radiates the warm heat previously stored to the air. In this way, the forced air convection and the contact efficiency of the air with the heat storage body 3 are improved, so that the required air conditioning conditions can be quickly achieved. In addition, each part of the surface of the heat storage body 3 comes into uniform contact with the air, and the heat radiation of each part of the surface of the heat storage body 3 becomes uniform.

Thus, if a latent heat storage agent 2 that stores heat radiation by solidification (cold storage) and radiates cold heat by melting (cooling) is used, cooling can be performed by the same operation as in the above example. In this case, it is advisable to force air to flow from bottom to top in the panel.

Further, the operation of the upper and lower dampers 14 and 15 may be manual, but may be opened and closed in synchronization with the driving and stopping of the blower 16.

That is, the switch 19 on the cover 1b of the panel may be operated to perform tuning under electrical control. Of course, the timer-controlled blower 16 and the upper and lower dampers 14 and 15 may be operated, or may be controlled using a sensor that detects the temperature in the building to be air-conditioned. Alternatively, for the dampers 14 and 15, various conventionally known shape memory materials, for example, shape memory alloys are used,
It is also conceivable to transform at a constant temperature to form an open shape or a closed shape, and to drive and stop the blower 16 in accordance with it.

Further, in the above example, the plate-shaped heat storage body 3 is supported on the side surface of the main body 1a constituting the box-shaped body 1, but the back surface 10 of the plate-shaped heat storage body 3 is the inner surface of the main body 1a. It is supported at 12 places, and an air passage is provided only between the surface 9 of the heat storage body 3 and the inner surface 11 of the cover 1b.
13 may be formed.

Further, as shown in FIGS. 7 and 8, peaks 21 and valleys 22 may be formed on the surface of the heat storage body 3 to increase the surface area thereof. In this example, the support member 6 of the heat storage body 3 is replaced by the heat storage body 3
An example is shown in which it is attached to the top of the upper portion 4, the end portion 7 of the support member 6 is bent upward, and this portion is attached to the inner surface of the side surface of the main body 1a.

Next, a second example of the present invention will be described with reference to FIG.

In this example, a Peltier element is used as the heating or cooling means 20, reference numeral 28 indicates a heat generating side conductor, and 29 indicates a heat absorbing side conductor. The heat generation side conductor 28 is introduced into the latent heat storage agent 2 of the heating heat storage body 3 in the one area 26, while the heat absorption side conductor 29 is in the other area 27 of the cooling heat storage body 3 of the latent heat storage agent 2. Has been introduced in. In this example, in the two heat storage bodies 3, the support member 6 is applied to the upper portion 4 of each, and the legs 23 of the support member 6 extend upward, while
The other areas 26 and 27 are divided and fixed to the upper surface 24 of the main body 1a.
On the other hand, the support member 6 is applied to the lower part 5 and the legs 23 of the support member 6 extend downward while the other region 26, 27 is provided.
It is fixed to the lower surface 25 of the main body 1a. Of course, several examples of this support method are conceivable.

As described above, in this example, the one area 26 and the other area 27 are divided, the blower 16 and the upper and lower dampers 14 and 15 are provided in each, and the inflow port 17 and the outflow port 18 are formed in each.
Therefore, focusing on one area 26, an air passage 13 is formed between the surface 9 of the heat storage body 3 and the inner surface 11 of the cover 1b in the one area 26, and focusing on the other area 27, the other area 27 An air passage 13 is formed between the surface 9 of the heat storage body 3 and the inner surface 12 of the main body 1a.

Based on such a configuration, at the time of heat storage, the heating / cooling means 20 as a Peltier element causes the heating conductor 28 in one region to generate heat, causing the latent heat storage agent 2 in the heat storage body 3 in the one region 26 to melt, The heat absorbing conductor 29 in the other area absorbs heat, and the latent heat storage agent 2 in the heat storage body 3 in the other area 27 is solidified. Therefore, warm heat is stored in the heat storage body 3 in the one area 26, and cold heat is stored in the heat storage body 3 in the other area 27.

Next, at the time of heat radiation, the upper and lower dampers 14 and 15 of the respective areas 26 and 27 are opened to drive the blower 16. On the other hand, in the area 26, air enters from the upper inlet 17, passes through the air passage 13, and flows out from the lower outlet 18. In the above process, the air and the heating heat storage body 3 are heat-exchanged with each other to heat the air.

On the other hand, in the area 27, air enters from the lower inlet 17,
It flows out of the upper outlet 18 through the air passage 13. In the above process, heat is exchanged between the air and the heat storage body 3 for cooling,
The air is cooled. The advantages during heat storage and during air conditioning are almost the same as those in the first example.

Thus, a plurality of Peltier elements may be provided, and the shortage of instantaneous capacity, which is a difficulty of the Peltier element itself, can be compensated by the combination with such a latent heat storage agent. In addition, by combining with this latent heat storage agent, the coefficient of performance of the Peltier element itself and its combination device can be improved.
