Heat storage type heater and method of controlling input and output of heat of the same

A method of controlling the input and output of heat to and from a heat-storing material comprising the steps of:

• externally supplying thermal energy to the heat-storing material capable of being supercooled and filled into a plurality of small containers together with a phase-segregation preventive agent by use of means for supplying heat, whereby the heat-storing material is melted;
• maintaining the heat-storing material in the supercooled state after the emission of sensible heat;
• and
• releasing the supercooled state of the heat-storing material by use of means for releasing the supercooled state of the heat-storing material, when the release of the stored heat energy is required, whereby the heat at the melting point is generated,
• wherein the time at which the supercooled state of the heat-storing material in the plurality of small containers is released is individually controlled for the small containers.

A method of controlling the input and output of heat to and from a heat-storing material comprising the steps of:

• externally supplying thermal energy to the heat-storing material capable of being supercooled and filled into a plurality of small containers together with a phase-segregation preventive agent by use of means for supplying heat, whereby a first emission of heat from the thermal radiation surface of the heat-storage type heater and melting of the heat-storing material are carried out;
• maintaining the heat-storing material in the supercooled state after the first emission of sensible heat;
• and
• allowing the heat-storing material to be spontaneously solidified when the heat-storing material decreases to a predetermined temperature, whereby the heat at the melting point is generated to perform a second emission of heat from the thermal radiation surface to an object to be heated.

• wherein the period from the first time at which the means for supplying heat to the heat-storing material is stopped after the emission of heat from the thermal radiation surface of the heat-storage type heater and the melting of the heat-storing material are carried out by use of the means for supplying heat, till the second time at which the heat-storage type heater starts to be spontaneously solidified is set by using a heat transfer coefficient from the heat-storage type heater to the outside, and the thermal characteristics, mass, and temperature of the heat-storing material as parameters.
