ABSTRACT:
A thermal energy storage system for storing heat from a solar collector in which latent heat transitions are used to store energy. Ternary systems are disclosed wherein the addition of a third compound gives an additional degree of freedom in controlling crystallization conditions. More specifically, the third compound is used to reduce the amount of incongruent melting found in binary systems of salt hydrates. Preferably, the compounds selected produce a composition whose crystal density approximately equals the liquid density in order to further reduce the segregation of the crystalline phase during the crystallization cycle. Preferred compositions of the storage medium are selected from the hydrates of sodium sulfate, sodium carbonate and dibasic sodium phosphate.
