Latent-heat storage media acting by solid-liq. phase transition comprise 78-82 wt.% H2O, 18-22 wt.% KCl, 0.2-1 wt.% NH4Cl and 2-6 vol.% glycerol. The compsns. freeze rapidly (within 17 hr.) in domestic freezers and are easier to prepare than prior art compsns. (cf. DE 2846988). The compsns. pref. comprise 79.89 wt.% H2O, 19.56 wt.% KCl, 0.55 wt.% NH4Cl, 3 vol.% glycerol and opt. 0.05-1 wt.% of a nucleating agent, e.g. Al2O3 or MgO.
