Abstract

A latent heat storage module includes a plurality of film packs configured to accommodate a phase change material configured to use phase change latent heat as a heat medium of room temperature (0° C. or more). A guide is configured to fix the plurality of film packs.

Claims

1. A latent heat storage module comprising:

a plurality of film packs configured to accommodate a phase change material, the phase change material configured to use phase change latent heat as a heat medium of room temperature (0°

C. or more); and

a guide configured to fix the plurality of film packs.

2. The latent heat storage module according to claim 1, further comprising a ballast configured to be fixed to the guide and prevent the film packs from floating on water.

3. The latent heat storage module according to claim 2, wherein the guide has a hollow into which the ballast is inserted.

4. The latent heat storage module according to claim 1, wherein the plurality of film packs are stacked, and

the guide stands facing end portions of the plurality of film packs and fixes the plurality of film packs.

5. The latent heat storage module according to claim 1, wherein the film packs are formed of a flexible material.

6. The latent heat storage module according to claim 1, further comprising a hot plate disposed on a surface of at least one of the film packs and configured to suppress deformation of the film packs.

7. The latent heat storage module according to claim 6, wherein the hot plate has a plurality of hills and valleys formed thereon, so as to form channels between the hot plate and the film packs.

8. The latent heat storage module according to claim 1, wherein the phase change material is an organic material.

9. The latent heat storage module according to claim 8, wherein the phase change material is an n-paraffin.

10. The latent heat storage module according to claim 9, wherein the phase change material is tetradecane (C₁₄H₃₀).

11. A latent heat storage apparatus comprising:

at least one latent heat storage module comprising a plurality of film packs configured to accommodate a phase change material, the phase change material configured to use phase change latent heat as a heat medium of room temperature (0°

C. or more);

a heat storage tank configured to accommodate the at least one latent heat storage module, the heat storage tank having water flowing therein; and

a plate disposed in the heat storage tank and configured to form a channel in which the water flows.

12. The latent heat storage apparatus according to claim 11, wherein the at least one latent heat storage module is a plurality of latent heat storage modules, and

the heat storage tank includes a channel flowing between the plurality of latent heat storage modules in a horizontal direction.

13. The latent heat storage apparatus according to claim 11, wherein the at least one latent heat storage module further comprises a guide configured to fix the plurality of film packs.
