New cascades for thermo-chemical refrigeration

A diagrammatical approach for the design of new thermo-chemical cascades for heat management purposes is proposed. The two key elements of this approach are: a method to automatically generate system architectures and a general approach to selecting appropriate materials. It is based on establishing an explicit correspondence between the exergy balance around a thermo chemical system, the properties of the reactants and the operational system parameters. A new auto thermal configuration involving two thermally coupled single effect processes is proposed and suitable materials for its implementation are identified. The method is illustrated for the design of an experimental installation for the testing of a thermo-chemical refrigeration system operated at distance from a heat source.
