A method and apparatus for storing heat
University of Kalmar, School of Pure and Applied Natural Sciences.
1980 (English)Patent (Other (popular science, discussion, etc.))
Abstract [en]

The invention relates to a method and apparatus for storing heat in a heat-of-fusion storage medium, e.g. a salt hydrate, and the heat exchange and mixing in conjunction with the taking of heat from the storage medium. In a closed system including a vapor chamber (5) and a chamber for a solid/liquid phase, the storage medium (2, 4) is brought into direct contact with a substance, i.e., a heat transfer medium (3) having the capacity of taking up heat from the storage medium by being vaporized. The vapor travels to the vapor chamber (5), and when heat is removed from the vapor, the vapor is caused to condense and the condensate returns to the storage medium. The substance has insignificant solubility in the storage medium and a density which is higher, or equal to the density of the storage medium in its liquid phase. Suitable combinations of storage medium and substance include calcium chloride hexahydrate and trifluorotrichloroethane or Clauber's salt and octafluorocyclobutane.
