HEAT-STORAGE GEL MATERIAL, USES THEREOF, AND PRODUCTION PROCESS THEREFOR

摘要

Provided are: a heat-storage gel material which in a sheet form can be prevented from deforming when vertically placed and which can be repeatedly used based on latent heat attributable to a phase transition; and a process for producing the heat-storage gel material. The heat-storage gel material comprises: a heat-storage liquid that comprises water and a heat-storage main ingredient dispersed therein and has a given phase transition temperature; and a shape-retaining material that has a network structure due to organic molecules and has been formed from agar or the like used in an amount of 0.2 wt% or more with respect to the heat-storage liquid. Due to this, the heat-storage gel material in a sheet form can be prevented from deforming when vertically placed and can be repeatedly used based on latent heat attributable to the phase transition. Furthermore, the heat-storage gel material can be produced from easily available, inexpensive materials.
