PURPOSE:A heat storing material, prepared by adding potassium acetate, ammonium acetate, sodium acetate and calcium acetate in specific amounts to acetic acid, operable in a desirable temperature range, chemically stable with little corrosion, and having flame retardancy and a large heat storing capacity. CONSTITUTION:A heat storing material, prepared by adding one or more of 10.05-15% potassium acetate, 10.05-18% ammonium acetate, 10.05-27% sodium acetate, 10.05-17% calcium acetate to acetic acid, and having a low melting point. For obtaining a low-melting point and freezing point, a salt, consisting essentially of potassium acetate having a high melting point depressing action may be added thereto. In case the freezing and melting step are carried out at a constant temperature and the flame retardancy and anticorrosion are required, a salt consisting essentially of sodium acetate may be added. EFFECT:Worakble in a temperature range of 5-20 deg.C. USE:Heat storing materials for cooling apparatuses. |
