Abstract
L'utilité de l'hexahydrate de chlorure de calcium comme fluide accumulateur est améliorée par addition, comme formateur de germes (our éviter le phénomène de surfusion), du carbonate de baryum, du carbonate de strontium, du fluorure de baryum, du fluorure-hydrofluorure de baryum et /ou du fluorure de strontium. Application aux pompes à chaleur, chauffage solaire.
