Storage container with heat storage material that provides heat to shelf included in storage container
The present invention is intended to provide a storage container that includes a shelf member holding a heat storage material arranged optimally. In a storage container that preserves an object at predetermined temperature, the storage container includes a storage room in which the object is preserved, and a shelf member disposed within the storage room, the shelf member including a flat portion on which the object is placed, and a heat storage material arranged to the flat portion in a way distributed depending on a temperature distribution near the flat portion within the storage room during steady operation. The heat storage material is arranged to be localized to a region of the flat portion at a relatively low-temperature side depending on the temperature distribution within the storage room.
1. A storage container that preserves an object at a predetermined temperature, the storage container comprising:
a storage room in which the object is preserved;
a shelf member disposed within the storage room, the shelf member including a flat portion on which the object is placed, and a heat storage material arranged to the flat portion in a way distributed depending on a temperature distribution near the flat portion within the storage room during steady operation; and
an opening/closing door to open and close the storage room; wherein
the heat storage material is arranged to be localized to a region of the flat portion at a low-temperature side with respect to the flat portion at a high-temperature side;
the heat storage material is arranged in the storage room and localized to a region toward a side opposite to the opening/closing door; and
the storage container maintains the predetermined temperature in the storage room by utilizing a latent heat when a phase of the heat storage material changes from a solid phase to a liquid phase during unsteady operation.
2. The storage container according to claim 1 , wherein
the shelf member has optical transparency.
3. The storage container according to claim 1 ,
wherein the heat storage material includes at least one of paraffin, an inorganic salt aqueous solution, an inorganic salt hydrate, and a clathrate hydrate.
4. The storage container according to claim 1 ,
wherein the heat storage material is arranged at a rear surface of the flat portion.
5. The storage container according to claim 4 ,
wherein the rear surface has a corrugated shape.
6. The storage container according to claim 1 ,
wherein the shelf member includes a tray disposed under the flat portion, and
the heat storage material is arranged on the tray.
7. The storage container according to claim 1 ,
wherein the heat storage material is packed with a packaging.
8. A storage container that preserves an object at a predetermined temperature, the storage container comprising:
a storage room in which the object is preserved;
a shelf member disposed within the storage room, the shelf member including a flat portion on which the object is placed, and a heat storage material arranged to the flat portion in a way distributed depending on a temperature distribution near the flat portion within the storage room during steady operation;
an opening/closing door to open and close the storage room; wherein
the heat storage material is arranged in a thickness, measured from the flat portion, increasing from a high-temperature side toward a low-temperature side depending on the temperature distribution;
the thickness of the heat storage material on an opposing side of the opening/closing door is greater than the thickness of the heat storage material on a side of the opening/closing door; and
the storage container maintains the predetermined temperature in the storage room by utilizing a latent heat when a phase of the heat storage material changes from a solid phase to a liquid phase during unsteady operation.
9. The storage container according to claim 8 ,
wherein the thickness of the heat storage material is continuously changed.
10. The storage container according to claim 8 ,
wherein the thickness of the heat storage material is discontinuously changed.
11. The storage container according to claim 8 ,
wherein the shelf member has optical transparency.
12. The storage container according to claim 8 ,
wherein the heat storage material includes at least one of paraffin, an inorganic salt aqueous solution, an inorganic salt hydrate, and a clathrate hydrate.
13. The storage container according to claim 8 ,
wherein the heat storage material is arranged at a rear surface of the flat portion.
14. The storage container according to claim 13 ,
wherein the rear surface has a corrugated shape.
15. The storage container according to claim 8 ,
wherein the shelf member includes a tray disposed under the flat portion, and the heat storage material is arranged on the tray.
16. The storage container according to claim 8 ,
wherein the heat storage material is packed with a packaging.
17. A storage container that preserves an object at a predetermined temperature, the storage container comprising:
a storage room in which the object is preserved;
a shelf member disposed within the storage room, the shelf member including a flat portion on which the object is placed, and a heat storage material arranged to the flat portion in a way distributed depending on a temperature distribution near the flat portion within the storage room during steady operation; and
an opening/closing door to open and close the storage room; wherein
the heat storage material includes a plurality of latent heat storage substances;
respective phase change temperatures of the plurality of latent heat storage substances are different depending on the temperature distribution;
the respective phase change temperatures of the plurality of latent heat storage substances arranged on a side of the opening/closing door is greater than the respective phase change temperatures of the plurality of latent heat storage materials arranged on an opposing side of the opening/closing door; and
the storage container maintains the predetermined temperature in the storage room by utilizing a latent heat when a phase of the heat storage material changes from a solid phase to a liquid phase during unsteady operation.
18. The storage container according to claim 17 ,
wherein the heat storage material includes at least one of paraffin, an inorganic salt aqueous solution, an inorganic salt hydrate, and a clathrate hydrate.
