Title: Heat storage system with variable storage cycle - has steel pipe system and uses different media depending on storage cycle
Inventor: SIEWERS HEINRICH DIPL PHYS DR
IPC: F28D17/02
Filed: 1974-09-16
Abstract: The thermal energy storage accommodates thermal daily, weekly, monthly and annual cycles. This thermal energy storage requires relatively little steel which improves its efficiency. The thermal energy is supplied and removed by a heat carrying medium in a pipe system. The thermal energy storage medium can have a vapour pressure which is lower than that of the water. For example gravel can be used as a thermal energy storage medium. Alternatively sand, eutectic salt mixtures and liquids such as water can be used. Gaseous heat carriers can also be used. The steel tubes of the storage system form a square lattice and the spacing of the pipes depends on the required storage cycle period. Similarly the heat storage material is selected in relation to the storage cycle.
