Abstract

A hydrogen-hydride absorption system comprising two reactor systems for chemically forming two hydride components, means for supplying heat to, and removing heat from, the component systems, means for partial thermal energy recovery from reactors in each of the systems, and means for conveying hydrogen between component reactor systems. A method for deriving refrigeration includes the steps of dehydrating the hydride of a first component reactor using a relatively low temperature thermal source and conveying the hydrogen to a second component reactor to be absorbed, and rejecting heat, decreasing the pressure of both component reactors along with partial heat recovery, supplying heat as a refrigeration load to dehydride the second component reactor and conveying the hydrogen to the first component reactor, and pressurizing both reactors through partial heat recovery and further heating. A method for deriving heat pump effects includes the steps of absorption of hydrogen conveyed from a second component reactor to a first component reactor with the subsequent release of heat at a high temperature, depressurizing both component reactors, dehydriding a first component reactor and conveying the hydrogen to a second component reactor with rejection of heat at a low temperature, and pressurizing the component reactors.
