Latent heat storage module and latent heat storage apparatus
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.
1. A latent heat storage apparatus comprising:
a plurality of latent heat storage modules each 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 plurality of latent heat storage modules, 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,
wherein each of the plurality of latent heat storage modules further comprises:
a guide configured to fix the plurality of film packs and having a hollow open at one end of the guide and a protrusion extending from another end of the guide, the protrusion being received in a hollow of an adjacent latent heat storage module among the plurality of latent heat storage modules;
a ballast configured to be fixed to the guide and prevent the film packs from floating on water; and
a hot plate disposed on a surface of at least one of the plurality of film packs and configured to suppress deformation of the at least one of the plurality of film packs,
wherein the ballast is arranged inside the hollow of the guide, and
wherein the hot plate has a plurality of hills and valleys formed thereon, so as to form channels between the plurality of hills and valleys of the hot plate and the plurality of film packs.
2. The latent heat storage apparatus according to claim 1 , wherein
the heat storage tank includes a channel flowing between the plurality of latent heat storage modules in a horizontal direction.
3. The latent heat storage apparatus according to claim 1 , wherein the ballast is arranged in the hollow of the guide, separately from the plurality of film packs.
4. The latent heat storage apparatus according to claim 1 , wherein the hot plate has the plurality of hills and valleys with respect to a direction in which the plurality of film packs are fixed to the guide.
