Heat-driven cooling generation method and apparatus using a metal hydride

摘要

PURPOSE: To continuously remote refrigerating cold of a low temperature by enhancing a pressure of operating hydrogen when the cold of metal hydride is generated. ;CONSTITUTION: Two sets of metal hydride containing vessels in which three types of metal hydrides of MH₁, MH₂, MH₃ of lower equilibrated hydrogen pressures are sequentially sealed as metal hydrides are employed. While hydrogens are moved from the MH₃ to the MH₂, the MH₁ in one set and moved from the MH₂, the MH₁ to the MH₃ in the other set, cooling for occluding the hydrogen of the MH₁ of the one set is conducted by using cold generated by hydrogen dissociation from the MH₃ of the other set. An operation for removing refrigerating cold to be generated by hydrogen dissociation from the MH₁ of the other set is alternately repeated between the two sets thereby to continuously remove the cold.;COPYRIGHT: (C)1993,JPO&Japio
