It is an object of the present invention to provide a thermal energy storage member having sufficient dissipation capabilities and a storage container using the same, and a refrigerator using the same. A thermal energy storage memberincludes: a thin-plate outer shape having an opposing upper faceand lower face; a thermal energy storage materialfilled in the inside of a package material; and a thermal conduction amount adjusting portionthat, in a case where difference occurs between temperature at the upper faceside and temperature at the lower faceside, reduces difference in thermal conduction amount per unit of time at the upper faceand the lower face

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.

It is an object of the present invention to provide a heat storage capsule capable of being readily produced and a heat storage member using the same. A heat storage capsuleincludes a heat storage materialreversibly changing into a hydrate of a salt and an aqueous solution of the salt and also includes a capsule coatingencapsulating the heat storage material. The capsule coatingincludes an inner sub-coatingand an outer sub-coating. The inner sub-coatingis a hydrogenated oil layer. The outer sub-coatingis made of a hydrophilic gel. The heat storage capsulehas a W/O/W three-layer structure.

An object is to provide a storage container including latent heat storage materials that provide a high cold insulation effect. A storage containerhas an electric cooling function and stores an object. The storage containerincludes at least one storage chamberthat stores the object; a first latent heat storage material A that is disposed in the storage chamberand has a predetermined phase change temperature; and a second latent heat storage material B that is disposed in the storage chamberand has a phase change temperature higher than the phase change temperature of the first latent heat storage material A.

An object of the present invention is to provide a readily produced and easily handled heat storage member. The heat storage memberhas a rectangular plane surface of, for example, 15 (cm)&#xd7;20 (cm), and has a thickness of, for example, 10 to 15 mm. The heat storage memberincludes a gelatinous latent heat storage material, and a large number of highly heat conductive fillersdispersed in the latent heat storage material. The highly heat conductive fillersare mixed in the latent heat storage materialwith a bias in dispersion density. In the rectangular plane surface of the heat storage member, a periodic pattern is formed in combination of cellular (cell-like) regions, which are demarcated by, for example, hexagonal contour linesand which are periodically arrayed in the vertical and horizontal directions.

A storage container can maintain a temperature inside a storage room not to cause a temperature distribution for a certain time even if the operation is stopped. In a storage containerstoring preserved goods and having an electrical cooling function, the storage containerincludes a container bodyand a door. A space enclosed by the container bodyand the doorforms a storage room. The container bodyand the doorhave respectively heat insulating portionsand heat accumulating portions. The heat accumulating portionsare each made of at least one type of material that causes liquid-solid phase transition at a temperature between a controllable temperature inside the storage roomand a living environmental temperature. A value obtained by dividing temperature conductivity of the material by an amount of the material used per unit area of a wall surface of the storage roomis smaller in the heat accumulating portionsarranged near a first area where a temperature is more apt to come closer to the living environmental temperature under a temperature distribution that is formed inside the storage roomwith changes over time after stop of cooling, than in the heat accumulating portionsarranged near a second area where a temperature is less apt to come closer to the living environmental temperature thereunder.
