Title:
化学蓄熱システム、及び蓄熱方法
Document Type and Number:
Japanese Patent JP7474441
Kind Code:
B2
Abstract:
To provide a chemical heat storage system and a heat storage method that can suitably advance a heat storage operation of a chemical heat storage material by restraining decrease in an absorption rate of water vapor caused by deliquescence of an absorbing material.SOLUTION: A chemical heat storage system 11 comprises a recovery flow passage L1 for sending water vapor to a recovery device 13 from a heat storage device 12. The chemical heat storage system 11 comprises a condenser 14 for condensing water vapor by using a cooling medium, a condensate flow passage L2 for sending water vapor to the condenser 14 from the heat storage device 12, and an opening/closing control unit 32 for controlling opening/closing of the recovery flow passage L1 and opening/closing of the condensate flow passage L2. The opening/closing control unit 32 is constituted so as to perform control for switching from a condenser operation step for closing the recovery flow passage L1, opening the condensate flow passage L2, and operating the condenser 14, to a recovery device operation step for closing the condensate flow passage L2, opening the recovery flow passage L1, and operating the recovery device 13, during a heat storage operation of a chemical heat storage material HM.SELECTED DRAWING: Figure 1
