<p>Method and apparatus for storing heat in a heat-of-fusion storage medium, e.g. a salt hydrate, and heat exchange and mixing in conjunction with taking 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 (3) having the capacity of taking up heat from the storage medium by being vaporized. Vapor goes over to the vapor chamber (5), and when taking out heat from the system, the vapor is caused to condense and the condensate to return to the storage medium. The substance shall have insignificant solubility in the storage medium and a density which is higher, or equal to the density of the storage medium liquid phase. Suitable combinations of storage medium and substance are such as calcium chloride hexahydrate and trifluorotrichloroethane or Glauber"s salt and octafluorocyclobutane. </p> |
