HEAT RECOVERY TYPE HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To allow a compact and high-output heat storage system to quickly perform warm-up when starting a vehicle and recover surplus heat existing in a heat source inside the vehicle after the warm-up to provide for the next warm-up.

SOLUTION: A heat recovery type heating device includes an ammonia buffer 12 constructed to enable fixation and desorption of ammonia as a chemical reaction medium, and chemical heat storage reactors 14 provided with a chemical heat storage material 24 that generates heat through a chemical reaction with ammonia supplied from the ammonia buffer 12, and that desorbs ammonia by means of surplus heat from the heat source and returns the ammonia to the ammonia buffer 12.
