することにより蓄熱する。[Prior Art] Conventionally, heat storage agents that utilize the latent heat of phase transition are known as heat storage agents that store heat and take it out again. This type of heat storage agent has a large amount of latent heat storage, and is usually made of a hydrated salt such as sodium acetate trihydrate or sodium sulfate decahydrate, and a carrier for this hydrated salt such as xanthan gum, which has a suitable usage temperature range.
Those made of hydrophilic polysaccharides such as guar gum and locust bean gum, or thickening agents such as starch and polyacrylic acid are known, and are heated above the melting point (transition temperature) of the heat storage agent stored in an insulated container. After absorbing heat, it is cooled to a temperature below the melting point and stored in a liquid phase state in which sensible heat is released.

At this time, the heat storage agent comes into contact with the outside air, which may cause the temperature to change or deteriorate due to the intrusion of airborne particles such as dust, bacteria, and spores, which shortens the life of the heat storage agent. .

方法が（シＩられる。[Means for Solving 1 Problem] According to the present invention, a heat storage agent having a supercooling property sealed in a container is heated to a temperature above the melting point by a heating means to substantially become a liquid state, and then heated to a temperature below the melting point. After cooling and releasing sensible heat, a stimulus for activation is applied to the heat storage agent in the supercooled liquid state to crystallize seed crystals of the heat storage agent, thereby crystallizing the heat storage agent. In the method for releasing supercooling of a heat storage agent having a supercooling property of releasing latent heat, a Peltier element having a cooling end and a heat generation end is provided at the bottom of the container, and heat is transferred from the heat storage agent in the container to the cooling end.

れるものではない。That is, the present invention provides a method for inducing release of supercooling from a supercooled heat storage agent by growing seed crystals in a part of the heat storage agent at a temperature at which the heat storage agent spontaneously forms a solid phase. By this, the remaining heat storage agent is produced in a solid phase, and the released latent heat is stored in the heat medium in the release container so that this latent heat can be easily utilized. Here, in the present invention, the heat storage agent is mainly composed of sodium acetate trihydrate,

過冷却解除方法。A heat storage agent with supercooling properties sealed in a container is heated to a temperature above its melting point by a heating means to substantially make it into a liquid state,
Subsequently, after cooling to below the melting point to release sensible heat, a stimulus for activation is applied to the heat storage agent in the supercooled liquid state,
In the method for canceling supercooling of a heat storage agent having a supercooling property in which the heat storage agent is crystallized by crystallizing seed crystals of the heat storage agent and releases latent heat, a cooling end and a heat generation end are provided outside the container. and a heat conductive member that conducts heat from the heat storage agent in the container to the cooling end, and a heat dissipation container housing a heat medium in the heat generating end, and the Peltier element in the heat storage agent is provided. It has a supercooling property characterized by cooling a part of the heat storage agent near the heat conductive member to a supercooling temperature or lower by an element, thereby releasing latent heat from the heat storage agent and storing the heat in the heat medium. How to release supercooling of heat storage agent.
