Abstract:
(EN) Provided is a latent-heat storage material containing a supercooling inhibitor which, when contained in an aqueous inorganic-salt solution containing sodium chloride, can separate out as crystals without fail upon cooling to inhibit supercooling and the inclusion of which little lowers the melting point or the quantity of latent heat. The latent-heat storage material contains an aqueous sodium chloride solution and comprises: the aqueous sodium chloride solution having a eutectic concentration; and disodium hydrogen phosphate contained in an amount not less than the saturation concentration at 0°C in the aqueous sodium chloride solution having the eutectic concentration. Due to this, the use of the latent-heat storage material containing the supercooling inhibitor, which can separate out as crystals without fail upon cooling to inhibit supercooling and the inclusion of which little lowers the melting point or the quantity of latent heat, makes it possible to keep cool by means of sufficient quantity of latent heat while inhibiting supercooling.
(FR) L'invention concerne un matériau de stockage de chaleur latente contenant un inhibiteur de surfusion qui, lorsqu'il est contenu dans une solution aqueuse de sel inorganique contenant du chlorure de sodium, peut se séparer sous la forme de cristaux sans défaillance lors du refroidissement en vue d'inhiber la surfusion et dont l'inclusion diminue peu le point de fusion ou la quantité de chaleur latente. Le matériau de stockage de chaleur latente contient une solution aqueuse de chlorure de sodium et comprend : la solution aqueuse de chlorure de sodium présentant une concentration eutectique ; et du phosphate d'hydrogène disodique contenu dans une quantité qui n'est pas inférieure à la concentration de saturation à 0 °C dans la solution aqueuse de chlorure de sodium présentant la concentration eutectique. En raison de cela, l'utilisation du matériau de stockage de chaleur latente contenant l'inhibiteur de surfusion, qui peut se séparer sous la forme de cristaux sans défaillance lors du refroidissement en vue d'inhiber la surfusion et dont l'inclusion diminue peu le point de fusion ou la quantité de chaleur latente, permet de maintenir le froid au moyen d'une quantité suffisante de chaleur latente, tout en inhibant la surfusion.
(JA) 塩化ナトリウムを含む無機塩水溶液に添加することで冷却時に確実に結晶が析出して過冷却を抑制でき、かつ添加による融点低下や潜熱量減少が小さい過冷却抑制剤を添加した潜熱蓄熱材を提供する。塩化ナトリウム水溶液を含む潜熱蓄熱材であって、共晶濃度の塩化ナトリウム水溶液と、前記共晶濃度の塩化ナトリウム水溶液に対して、0℃における飽和濃度となる量以上の量のリン酸水素二ナトリウムと、を含む。これにより、冷却時に確実に結晶が析出して過冷却を抑制でき、かつ添加による融点低下や潜熱量減少が小さい過冷却抑制剤を添加した潜熱蓄熱材を用いて、過冷却を抑制しつつ十分な潜熱量により保冷することができる。
