COLD/HEAT INSULATED CONTAINER

摘要

The present invention provides a cold/heat insulated container (20) including: a container wall (1) that defines a space (10) capable of accommodating an article; a device (3) containing a reaction chamber (3a) that accommodates a thermal storage material, a condensing/evaporating chamber (3b) for condensing or evaporating a condensable component generated by an endothermic reaction of the thermal storage material, and a connection section (3c) that connects the reaction chamber (3a) and the condensing/evaporating chamber (3b) so as to allow the condensable component to move between the reaction chamber (3a) and the condensing/evaporating chamber (3b); a valve (5) provided in the connection section (3c); a temperature sensor (7) that detects the temperature in the space (10); and a control section (9) that controls opening/closing of the valve (5) on the basis of the temperature in the space (10) detected by the temperature sensor (7). When the valve (5) is in the closed state, between the reaction chamber (3a) and the condensing/evaporating chamber (3b), the device (3) is in a non-equilibrium state. When the valve (5) is turned from the closed state to the open state by the control section (9), between the reaction chamber (3a) and the condensing/evaporating chamber (3b), the device (3) is shifted toward an equilibrium state from the non-equilibrium state, and the space (10) is heated or cooled.
