Abstract
The present invention relates to a latent heat storage material composition comprising 70 to 90 wt % of sodium sulfate decahydrate, 3 to 17 wt % of ammonium chloride, 1 to 13 w % of sodium chloride and 1 to 13 wt % of ammonium sulfate. The composition can be frozen with cooled water of 4.degree. to 5.degree. C., has a melting point of 10.degree. to 13.degree. C., has large latent heat at the melting point and exhibits excellent long-term performance.
