HEATING MEANS FOR STORING

摘要

A storage medium is intended to store thermal energy in a high capacity manner with relatively high heat transfer. The medium includes activated alumina and an aqueous medium and the storage medium may be usable at low temperatures and up to about 200 DEG C. Heat exchange with the storage medium utilises the specific heat of the medium and enthalpy arising out of reversible endothermic and exothermic chemical changes to give high thermal storage capacities which can be enhanced if the range includes a phase change. The thermal storage medium can be used in storage systems such as air conditioning and in systems where the thermal energy is utilised at locations remote from the charging station.
