HEAT STORAGE CONTAINER AND TEMPERATURE RETENTION COMPARTMENT

The purpose of the present invention is to provide a heat storage container or a temperature retention compartment which has a high temperature retention capacity and is capable of efficiently cooling a latent heat storage material. The heat storage container (100) comprises: an enclosed space region (1) of a prescribed volume; a heat transfer region (10) which is disposed on an inner wall of the enclosed space region and transfers heat in order to control the temperature inside the enclosed space region (1); a latent heat storage material (3) disposed in the heat transfer region; and heat transfer region exposure sections (6) wherein the latent heat storage material (3) is not disposed and wherein the heat transfer region (10) is exposed. A refrigerator (501) comprises: a heat exchanger (537) which generates cold air with a temperature lower than the ambient temperature; a blower (506) which generates cold blasts by subjecting the cold air to forced convection and which blows the cold blasts; and a latent heat storage material (503) which is disposed in such a manner as to be directly exposed to the cold blasts or in such a manner that the cold from the cold blasts which directly strikes a heat receiving section is indirectly transmitted via the heat receiving section and which accumulates or releases thermal energy through phase transitions.
