PURPOSE:To avoid the occurrence of troubles such as the failure of the action of a supercooling preventive material due to the rise of the temperature of a latent heat storage material during the heat storage by a heater, supercooling during the heat releasing period, etc., by a method in which the arranging density of the corresponding portion of a container to be covered with a heat insulator with high probability is made higher for a temperature sensor wire to be provided. CONSTITUTION:In a temperature sensor wire 7, the arranging density of the corresponding portion of containers 3-A and 3-B on the end portion of the device is made higher, but that of the corresponding portion of the central container 3-C of the device is made lower. In such a constitution, when the heat insulator 9 on the container 3-A is covered with a heat insulating material 10 such as a cushion, etc., when heat is stored in a latent heat storage material 1 by a heater 5, the heat amount to be released from the heat insulator 9 is reduced and the temperature is raised. However, since impedance is varied tangentially and a contributory rate to all impedance becomes greater, the supply of electric current to the heater 5 is controlled by the controller 8 at temperatures below the heat resistance temperature of a supercooling preventive material 2 and thereby the occurrence of supercooling is prevented. |
