=== embodiment ===
<< About the structure of the display case >>
FIG. 1 is a schematic plan view for explaining the arrangement of the display case 10 of the present embodiment, and FIG. 2 is a perspective view of the display case 10 of the present embodiment.

  In the following, each direction is set as shown in the figure. That is, two orthogonal directions in the horizontal plane are defined as a front-rear direction and a left-right direction. Of these, the direction connecting the front and back of the display case 10 is referred to as the front-rear direction, and the front side as viewed from the back of the display case 10 is “front”, and the opposite side is “rear”. In the left-right direction, the right side when viewing the front side from the rear side is “right” and the left side is “left”. In addition, a direction perpendicular to the front-rear direction and the left-right direction is defined as a vertical direction (vertical direction), the ceiling side is defined as “up”, and the opposite side (floor side) is defined as “down”.

  The outer wall 1 shown in FIG. 1 is a wall in a facility such as a museum or a museum, and is a wall at a boundary between a room and the outside. That is, the front side of the outer wall 1 is indoors (inside the facility: here, the exhibition room), and the rear side of the outer wall 1 is outdoor (outside the facility).

  The display case 10 (corresponding to a display device) of the present embodiment is provided in front of the outer wall 1 (display room). The display case 10 is a case for displaying an exhibit, such as an art work or a printed matter, so as to be able to be appreciated in the facility. In addition, the above facilities are fully equipped with air conditioning equipment not shown.

  In the present embodiment, the air conditioner operates in a predetermined time zone of 24 hours a day (for example, facility opening time). Thereby, the air conditioned by the air conditioning equipment (hereinafter, referred to as conditioned air) is supplied to the exhibition room, and the temperature is adjusted to be appropriate. On the other hand, in other time periods, the operation of the air conditioner is stopped to save power. However, when the operation of the air conditioner is stopped in this way, the conditioned air is not supplied to the exhibition room, and the storage environment of the exhibited items may be deteriorated. Therefore, in the display case 10 according to the present embodiment, as described later, the storage environment of the exhibits is improved.

  As shown in FIG. 2, the display case 10 includes a heat insulating wall portion 11, a housing portion 12, an upper heat storage portion 13, an upper heat transfer portion 14, a mounting plate 15, a ventilation gap 16, a humidity control case 17, and a lower heat A transmission unit 18 and a lower heat storage unit 19 are provided.

  The heat insulating wall portion 11 is a plate-shaped wall member provided on a surface of the display case 10 facing the outer wall 1 (in this embodiment, a rear surface of the display case 10). The heat insulating wall portion 11 has heat insulating performance and is a member that is hardly affected by the external environment (such as a temperature change) from the external wall 1. The front, right, and left sides of the display case 10 are formed of a transparent material (eg, glass). As a result, the front, right and left sides become viewing surfaces, and the exhibits can be viewed.

  FIG. 3A is a diagram illustrating an example of a configuration of the heat insulating wall portion 11. The heat insulating wall portion 11 is formed by laminating the LGS 2, the heat insulating material 3, the plaster board 4, the moisture-proof sheet 5, the plywood 6, the adhesive 7, and the cloth 8 in this order from the outside (outer wall 1 side).

  LGS2 is a lightweight steel (steel) base material. The heat insulating material 3 is a member having heat insulating performance. Details of the heat insulating material 3 will be described later. The blaster board (also called gypsum board) 4 is a plate-like panel made of gypsum. The moisture-proof sheet 5 is a sheet that prevents moisture and water vapor from permeating to prevent dew condensation, and is made of polyethylene or the like. The plywood 6 is a wooden board obtained by laminating thinly cut veneers and bonding them by heat and pressure. The cloth 8 is an interior finishing material, and is attached to the surface of the plywood 6 with an adhesive 7.

  As described above, since the heat insulating material 3 is provided, the heat insulating wall portion 11 is hardly affected by the external environment from the outer wall 1. In this embodiment, a vacuum heat insulating material is used as the heat insulating material 3. The vacuum heat insulating material is a heat insulating material in which a core material having a porous structure is covered with a jacket material, and then the inside of the jacket material is reduced in pressure and hermetically sealed. The vacuum heat insulating material has an extremely low heat conduction and a high heat insulating performance. Further, the vacuum heat insulating material can be thinner and lighter than other heat insulating materials. Therefore, by using a vacuum heat insulating material as the heat insulating material 3, the heat insulating performance can be improved, the thickness of the heat insulating wall portion 11 can be reduced, and the space of the housing portion 12 can be widened. Further, the display case 10 can be reduced in weight.

  FIG. 3B is a diagram illustrating another example of the configuration of the heat insulating wall portion 11. 3A are denoted by the same reference numerals. In this example, the heat insulating material 3 is provided between the plaster board 4 and the moisture-proof sheet 5. Also in this case, it is possible to reduce the influence of the external environment (such as temperature change). Note that the heat insulating wall portion 11 is not limited to FIGS. 3A and 3B and may have another configuration. However, when the moisture-proof sheet 5 is provided as in the present embodiment, it is desirable that the heat insulating material 3 is disposed outside the moisture-proof sheet 5.

The latent heat storage material 133 is a heat storage material that stores the temperature of the air taken into the upper heat storage unit 13, and is a heat storage material that utilizes latent heat when a substance undergoes a phase change between a solid phase and a liquid phase. . That is, when the temperature of the latent heat storage material 133 in the solid phase rises and reaches the melting point, the latent heat storage material 133 melts and absorbs heat of fusion from the outside. On the other hand, when the temperature of the liquid-phase latent heat storage material 133 decreases and reaches the freezing point, the latent heat storage material 133 solidifies and releases heat of solidification to the outside. In general, the melting point and the freezing point are the same, and this point (temperature) is hereinafter also referred to as a phase change point. The latent heat storage material 133 is for cooling, and in the present embodiment, the phase change point is set to 28 ° C.

  The upper heat transfer section 14 is a member having a high thermal conductivity, and is provided between the housing section 12 and the upper heat storage section 13. The upper heat transfer section 14 partitions the housing section 12 and the upper heat storage section 13 and transmits the temperature of the upper heat storage section 13 to the housing section 12.

  The ventilation gap 16 is a gap provided on the rear side of the mounting plate 15 and communicates the housing section 12 and the humidity control case 17. As a result, the accommodation section 12 and the humidity control case 17 can be ventilated.

The upper heat transfer section 14 partitions the storage section 12 and the lower heat storage section 19, and transmits the temperature of the lower heat storage section 19 to the storage section 12 via the humidity control case 17 and the ventilation gap 16.

  The lower heat storage unit 19 is provided below the housing unit 12 (more specifically, below the lower heat transfer unit 18). The lower heat storage unit 19 is a part that takes in conditioned air (warm air) during heating to store heat. The lower heat storage unit 19 is provided with an inlet 191, an outlet 192, and a latent heat storage material 193.

However, the latent heat storage material 193 is for heating, and the phase change point is set to 20 ° C. in the present embodiment.

<< About the exhibition method >>
First, as shown in FIG. 1, the display case 10 is disposed inside the facility (here, the exhibition room), and the exhibit is stored in the storage section 12 of the display case 10. In the storage section 12, an optimal humidity is secured by the humidity control agent 20. In summer and winter, the air conditioner is operated during the period when the facility is open (a predetermined time period of 24 hours a day) to supply air to the exhibition room. Thereby, the temperature of the exhibition room is adjusted to an appropriate temperature. On the other hand, in other time zones, the operation of the air conditioner is stopped. Although no air-conditioning air is supplied to the exhibition room, the display case 10 of the present embodiment can improve the storage environment of the exhibits as described later.

<When cooling>
When cooling is used in summer or the like, the fan 131a of the intake 131 is driven in conjunction with the operation of the air conditioner (cooling). Thereby, the conditioned air (cool air) is taken into the upper heat storage unit 13 from the intake 131. Due to this cool air, the temperature of the upper heat storage unit 13 becomes lower than the phase change point of the latent heat storage material 133 (28 ° C. in the present embodiment), and the latent heat storage material 133 becomes a solid phase.

  When the operation of the air conditioning equipment is stopped, the supply of the conditioned air (cool air) is stopped, so that the indoor temperature rises. When the temperature reaches the phase change point (28 ° C.) of the latent heat storage material 133, the latent heat storage material 133 gradually changes from a solid phase to a liquid phase. The latent heat storage material 133 absorbs heat of fusion from the surroundings (in other words, releases cold heat) during the phase change from the solid phase to the liquid phase. This cold heat (temperature) is transmitted to the storage section 12 via the upper heat transmission section 14. Further, since the display device 10 is provided with the heat insulating wall portion 11 on the surface facing the outer wall 1, it is hardly affected by temperature changes outside the facility. Thereby, an increase in the temperature of the storage section 12 can be suppressed, and the storage environment of the exhibits can be improved.

<When heating>
When heating is used in winter or the like, the fan 191a of the intake 191 is driven in conjunction with the operation of the air conditioner (heating). Thereby, the conditioned air (warm air) is taken into the lower heat storage unit 19 from the lower heat storage unit 19. Due to this warm air, the temperature of the lower heat storage unit 19 becomes higher than the phase change point (20 ° C. in the present embodiment) of the latent heat storage material 193, and the latent heat storage material 193 becomes a liquid phase.

  When the operation of the air conditioning equipment is stopped, the supply of the conditioned air (warm air) is stopped, so that the indoor temperature decreases. When the temperature reaches the phase change point (20 ° C.) of the latent heat storage material 193, the latent heat storage material 193 gradually changes from a liquid phase to a solid phase. Then, the latent heat storage material 193 emits heat of solidification to the surroundings during the phase change from the liquid phase to the solid phase. This heat of solidification (temperature) is transmitted to the storage section 12 via the lower heat transfer section 18 and the humidity control case 17. Further, since the display device 10 is provided with the heat insulating wall portion 11 on the surface facing the outer wall 1, it is hardly affected by temperature changes outside the facility. Thus, a decrease in the temperature of the storage section 12 can be suppressed, and deterioration of the storage environment of the exhibits can be suppressed.

  In the present embodiment, the latent heat storage material 133 is provided in the upper heat storage unit 13 and the latent heat storage material 193 is provided in the lower heat storage unit 19. However, the latent heat storage material 133 and the latent heat storage material 193 may be omitted. Also in this case, the air (air) during operation of the air conditioner is stored and stored in the internal space of the upper heat storage unit 13 and the lower heat storage unit 19 to store the heat (temperature) when the air conditioner stops. It can be transmitted to the unit 12. Alternatively, the latent heat storage material 133 may be detached from the upper heat storage unit 13, changed in phase at another location, and then reattached. Similarly, the latent heat storage material 193 may be removed from the lower heat storage unit 19, changed in phase at another location, and then reattached.

  In the present embodiment, the upper heat storage unit 13 is used for cooling, and the lower heat storage unit 19 is used for heating. That is, the upper heat storage unit 13 may be used for heating, and the lower heat storage unit 19 may be used for cooling. However, since the warm air rises and the cool air falls, the present embodiment has better heat (temperature) transmission efficiency. That is, it is possible to efficiently suppress an increase or decrease in the temperature of the storage unit 12.

  The phase change points of the latent heat storage material 133 and the latent heat storage material 193 may be set to be substantially the same, and both the upper heat storage unit 13 and the lower heat storage unit 19 may be used for cooling or both for heating.

  Further, only one of the upper heat storage unit 13 and the lower heat storage unit 19 may be provided. In this case, the heat storage unit may be used for cooling or heating, or may be used for both cooling and heating.

For example, in FIG. 5, the inlet 131 and the outlet 132 may be provided vertically on the front surface of the upper heat storage unit 13.

  By providing the air-conditioning air intake 131 (191) and the exhaust port 132 (192) on the surface where the heat-insulating wall 11 (vacuum heat-insulating material) is not provided, it is possible to suppress a decrease in heat-insulating performance. Can be.
