The composition based on calcium chloride hexahydrate for the storage of heat by change of phase and for its preparation

摘要

The composition contains, relative to the weight of calcium chloride, from 2 to 15% by weight of a potassium nitrogen compound and from 2 to 15% by weight of ammonium chloride, the weight relationship between the potassium nitrogen compound and ammonium chloride being preferably between 0.4 and 2. The composition, which has a melting point of 19 to 22 DEG C. is suitable, in particular, for heat conditioning of dwellings and of covered cultivation installations.
