Abstract

Official abstract text for this publication.

A chemical heat storage device includes a reactor which has a heat storage material which generates heat by a chemical reaction with a reactive medium and desorbs the reactive medium by heat absorption, and a receptacle which houses the heat storage material therein; a reservoir which stores the reactive medium; a connecting pipe through which the reactor and the reservoir communicate with each other and the reactive medium is allowed to flow between the reactor and the reservoir, wherein the reactive medium is ammonia, the receptacle is made of a metallic material (for example, stainless steel), and at least a portion of an inner surface of the receptacle which comes into contact with the ammonia is formed with a nickel layer containing 90% nickel by mass or more.

First claim

Opening claim text (preview).

The invention claimed is: 1. A chemical heat storage device comprising: a reactor which has a heat storage material which generates heat by a chemical reaction with a reactive medium and desorbs the reactive medium by heat absorption, and a receptacle which houses the heat storage material therein; a reservoir which stores the reactive medium; and a connecting pipe through which the reactor and the reservoir communicate with each other and the reactive medium is allowed to flow between the reactor and the reservoir, wherein the reactive medium is ammonia, the receptacle is made of a metallic material, and at least a portion of an inner surface of the receptacle which comes into contact with the ammonia is formed with a nickel layer containing 90% nickel by mass or more. 2. The chemical heat storage device according to claim 1 , wherein the nickel layer is formed by a nickel plating process. 3. The chemical heat storage device according to claim 1 , wherein the receptacle is manufactured using a clad material formed of a plate material made of the metallic material and a plate material made of nickel, and the nickel layer is formed of the plate material made of nickel in the clad material. 4. The chemical heat storage device according to claim 1 , wherein the metallic material is stainless steel. 5. The chemical heat storage device according to claim 1 , wherein the reactor has the plurality of heat storage materials and a plurality of heat exchange sections, and the plurality of heat storage materials and the plurality of heat exchange sections are alternately laminated.
