Abstract: An object of the present invention is to inhibit the phase separation of a salt hydrate used as a main component of a heat storage material. The inventors have made the present invention based on findings that when added to a heat storage material including a salt hydrate and a supercooling inhibitor, graphene oxide can inhibit the phase separation of the salt hydrate. The present invention is directed to a heat storage material including: a salt hydrate as a main component; a supercooling inhibitor that promotes solidification of the salt hydrate; and graphene oxide. The technical features help to inhibit the phase separation of salt hydrates.

Abstract: An object is to sufficiently lower the melting point of a heat storage material that includes sodium acetate trihydrate as a main component and to sufficiently narrow the range of a melting peak while ensuring a sufficient heat storage density. A heat storage material contains sodium acetate trihydrate that serves as a main component 21 and a melting point adjuster that is any one of potassium nitrate, potassium chloride or sodium nitrate. The content of the melting point adjuster in the heat storage material is equal to or greater than 10% by weight. The present inventors have confirmed that by setting the content of the melting point adjuster to be equal to or greater than 10% by weight, the range of a melting peak serving as a melting temperature range can be sufficiently narrowed.

Abstract: An object of the present invention is to sinter a MOF sufficiently firmly at a low temperature while ensuring the MOF sufficient adsorption performance. The present inventors have found that if a binder having a hydroxy group is mixed with a MOF having a terephthalic acid-based ligand, a sufficiently firm MOF can be obtained by sintering at a low temperature while ensuring sufficient adsorption performance, and thus the present invention has been completed. The MOF sintered body of the present invention contains a MOF having a terephthalic acid-based ligand and a binder having a hydroxy group OH. According to the present aspect, the sufficiently firm MOF can be obtained by sintering at a low temperature while ensuring sufficient adsorption performance.

Abstract: To adsorb an adsorbate rapidly on a heat storage material with good energy efficiency. A chemical heat storage device includes an adsorbate, a heat storage material, and a sprayer. The adsorbate is in a liquid state at normal temperature. The heat storage material releases heat of adsorption in response to adsorption of the adsorbate on the heat storage material and stores the heat of adsorption in response to desorption of the adsorbate from the heat storage material. The sprayer sprays the adsorbate on the heat storage material in a heat release period of causing the heat storage material to release the heat of adsorption. With the above-described configuration, it is possible to increase a speed of diffusion of the adsorbate in the heat storage material through spraying of the adsorbate on the heat storage material.
