Latent heat regenerating apparatus

A latent heat regenerating apparatus includes a regenerative tank wherein a latent heat regenerative material is housed. The material has a phase transition temperature and a supercooling-release temperature and is capable of maintaining a supercooled-state in a temperature range between the temperatures. A thermoelectric cooling element is located in the regenerative material so as to control supercooling of the material. The element has a heat radiating portion for radiating heat into the material and a heat absorbing portion for absorbing heat from the material, thereby cooling that portion of the material near the absorbing portion to a temperature lower than the supercooling-release temperature.
