A chemical heat pump using dehydration of sodium carbonate decahydrate for generating cold heat is proposed as a method contributing to the load leveling of electricity. Experiments on the dehydration of decahydrate in a packed bed reactor showed the generation of cold heat with sufficiently low temperature. The heat pump characteristics measured were simulated by use of dehydration kinetics of a single particle. Improvement of the heat‐transfer rate in the bed is a key factor for creating an efficient system.
