HEAT STORAGE DEVICE

摘要

The invention provides a heat storage device including two or more reactors including a first reactor having a heat storage material containing a physical adsorbent that stores heat when water vapor is desorbed and radiates heat when the water vapor is immobilized by physical adsorption, and a second reactor having a heat storage material containing a chemical heat storage material that stores heat when water vapor is desorbed and radiates heat when the water vapor is immobilized by a chemical reaction; and a water vapor pipe connecting the two or more reactors to cause the water vapor to flow between the two or more reactors, wherein the water vapor desorbed from one of the reactors is immobilized by the other reactor by using a difference in water vapor pressure between the two or more reactors.
