Abstract
A method is disclosed for increasing the cycle stability of a latent heat accumulator medium consisting essentially of a pure or saturated sodium sulfate salt melt. The cycle stability is increased by adding sulfuric acid to the latent heat accumulator medium in an amount of from 0.5 to 3%, by weight, based on the weight of the latent heat accumulator medium. The pH value of the latent heat accumulator medium is lowered without precipitation of impurities or the occurance of supercooling in the latent heat accumulator medium.
