Description
JAERI has been developing a hydrogen storage type high temperature chemical heat pump not only to amplify thermal energy of the temperature 373 K to 1273 K as well as store mass hydrogen energy, but hydrogen transportation to remote side. To testify the concept of this type of heat pump, heat pump element test facility was constructed and has been testing its performance. Heat conversion from 773 K to 1173 K was achieved with high heat exchanged coefficient by helium cooling technique. Present paper reports the recent tests results of the facility, including R and D on metal-hydride and structural materials for this system. (author)
