PURPOSE:To carry out such a pretreatment that a nucleating agent is added to a latent heat-type heat storage material followed by heating to specified temperatures and then cooling to solidify said material once, thus preventing supercooling in the heat release and ensuring ready solidification at temperatures near the melting point to make the absorption and release of the latent heat smooth. CONSTITUTION:The objective pretreatment is carried out in such a manner that a nucleating agent (pref. sodium tertiary phosphate) is added to a latent heat-type heat storage material (pref. sodium acetate trihydrate) followed by heating to 85-110 deg.C and then cooling, thus solidifying said material once.
