ABSTRACT:
This invention concerns the storage and conveyance of thermal energy at low temperature, by using the latent heat produced by a substance during changes of state.
This substance consists of a salt producing considerable latent heat during change of state, such as Na.sub.2 SO.sub.4, 10 H.sub.2 O, combined closely with a nucleating agent such as borax and dispersed in an oil to which an emulsifying agent has been added.
This product is particularly suitable for storage of solar energy at low temperature and for heating of enclosed areas.
