Hydrated calcium-chloride material accumulating heat by phase changing at a temperature of about 24.5 degrees C.

摘要

1. Material based on calcium chloride hydrate accumulating heat by means of a phase change, characterized in that it consists of a eutectic which has a determined solid-liquid phase change temperature of 24.5 degrees C +- 0.6 degrees C which is made up of : 47.7% +- 0.5% by weight of calcium chloride (CaCl2 ), 44% +- 0.5% by weight of water, 3.4% +- 0.3% by weight of ammonium chloride (NH4 Cl), 4.5% +- 0.3% by weight of potassium chloride (KCl), and between 0.1% and 1% of sodium chloride (NaCl).
