【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、潜熱蓄熱材に関する。更に詳しくは。[Detailed description of the invention] [Industrial application field] The present invention relates to a latent heat storage material. For more details.
過冷却状態を安定化させた潜熱蓄熱材に関する。This invention relates to a latent heat storage material that stabilizes the supercooled state.

冷却液体と接触させ、固化せしめる構造を有している。The present applicant has previously proposed various devices for the arbitrary assimilation of supercooled liquids, which solidify the latent heat storage material in a supercooled state as necessary and make it possible to release the latent heat at a predetermined temperature. No. 63-6389, No. 63-14089, No. 63-14090, No. 63-135789, and No. 64-46582). All of these solidification devices have a structure in which a solid heat storage material or a nucleating agent-contact heat storage material is housed in the device, and is brought into contact with a supercooled liquid at a desired time using appropriate means to solidify it. .
また、過冷却液体を封入した柔軟性材料製密封容器の変

所望の時期に固化せしめる装置も提案されている（実願
昭６３−１５３３９０号）。Furthermore, an apparatus has been proposed in which the supercooled liquid is solidified at a desired time using a spring that deforms with the deformation of a sealed container made of a flexible material containing the supercooled liquid (Utility Application No. 153390/1982).
このような過冷却液体の任意固化装置において。 In such an optional solidification device for supercooled liquids.
所望の時期に固化せしめる迄は、過冷却液体がその状態
に安定化されていなければならないという当然の要求が
存在する。There is a natural requirement that the supercooled liquid must be stabilized in that state until solidification occurs at the desired time.
本発明の目的は、酢酸ナトリウム・３水和物系の潜熱蓄
熱材において、その過冷却状態を安定化せしめたものを
提供することにある。An object of the present invention is to provide a sodium acetate trihydrate-based latent heat storage material whose supercooled state is stabilized.

り、過冷却状態を安定に保持することができる。This object of the present invention is achieved by adding zinc acetate or lead acetate to sodium acetate trihydrate.6 Sodium acetate trihydrate CH3COONa 3H20
(melting point 58℃) is 0 to -20℃ even in supercooled state.
Because assimilation begins in the vicinity, it will solidify naturally in sub-zero environments, making it impossible to collect the latent heat when necessary using the various optional solidification devices mentioned above. However, to this, zinc acetate (anhydrous or dihydrate) or lead acetate (anhydrous or trihydrate) is added at a ratio of about 0.5 to 30% per sodium acetate trihydrate.
By adding % by weight, preferably about 1 to 20% by weight, a supercooled state can be stably maintained.

ラス転移してしまう程である。By adding zinc acetate or lead acetate to sodium acetate trihydrate, the supercooled state of sodium acetate trihydrate can be stabilized, and the degree of stabilization is limited to 160°C. However, the supercooled liquid does not solidify, and the supercooled liquid undergoes a glass transition.
次に、実施例について本発明を説明する。 Next, the present invention will be explained with reference to examples.
