Development of media for dynamic latent heat storage for the low-temperature range. Part 1: thermal analyses of selected salt hydrate systems
Technical Report

OSTI ID:5744923
Phase-change temperatures and phase-change enthalpies of seventeen salt hydrates, three double salts, and four eutectics were measured thermodynamically and the results reported herein. Good results were obtained, especially for congruently melting salt hydrates. Incongruently melting salt hydrates appear less suitable for heat storage applications. The influence of the second phase - water, acid and hydroxide - to the latent heat is described. From these results, basic values of the working temperatures and storage capabilities of various storage media compositions may be derived.
